  1. Nah I will probably just use glasses more. Incandescent lights blow in my house (though the power company is finally putting in new poles) and even then I like a lot of lights on and the power consumption is not acceptable to me. Switching to LED save me FUCK TONS in usage electricity usage since I love brightly lit rooms. I like fluorescent lights a lot, but I have a friend that can see their 60Hz flicker which triggers headaches, even migraines sometimes I try to keep them to a minimum to not be a dick. (One of those people that wears sunglasses indoors) They're also not quite as power efficient. Led lights are fine for me, I keep them warm in color and it's a lot more mild in terms of blue light. Its still there, and I turn lights off at night more than I used to as a result, but there's really nothing I can do about it and it never feels particularly intense to me. I do have one room on with big warm fluorescent shop lights and it's kinda better on the eyes after a long day but not really enough to matter. It's the street lights and car headlamps I hate. LED is not as bad if you get to choose the type you want. I mean sunlight has blue light as well lol
  2. Apple's claiming their headquarters is worth only $200

    This is either fraud or transparent stalling to hold up their taxes in legal proceedings. Either way, there's a difference between paying the least amount of taxes you are legally liable to, which every company has the 'responsibility' to do, and whatever the fuck this practice is. Kinda really scummy.
  3. @LAwLz@dalekphalm I haven't just abandoned the thread. I figured the fair thing to do would be test it. Was at a point where you clearly know your monitors, and I don't know the concepts behind light well enough to properly explain any further on the filtering, and testing is way better than me sounding like a know-it-all asshole, because I really don't I'm not an expert or anything. I bought a cheap spectroscope last week and got it Friday but I've been busy. It did show a light signature on ccfl that was different than led (seperate lines and not a spectrum on full white), matched the fluorescent lights in my house. It also showed some really interesting things on some of my screens when testing certain colors. I'll be writing a nice detailed post with lots of tests you can replicate (it's like 8$ and it's really cool). If possible, I'd like you to add to it eventually since you have a ccfl ips monitor. With more research on monitors (especially on laptops) I plan to write a separate thread on the subject and show how to test after I have more time to research this and learn more about what kinda of monitors are out there, expecially in laptops. Here's the one I bought https://www.amazon.com/gp/product/B00B84DGDA/ It's not perfect obviously, but it gives a great general idea. The scale has a tad bit of a paralax effect so you wont get the exact number, but the actual spectrum it shows is very clear with bright light bulbs, and works decently for screens. My phone can't focus on it and it's really hard to hold both this and my camera and focus while not scratching my lens lol. I'll need to set up a tripod with the spectroscope attached to it and experiment for consistent pics. The sensor had a difficult time reacting to this refracted light as well for some reason, made a really interesting lens flare as well if I didn't get it at the right angle. Here's some preview pics to show at least one ccfl vs led case, my next pics will be much better. (These were all dark room only screen on). The LED backlight TN is the Acer XB2h1H and the CCFL one is an old LG W2361V. Neither really have any adjustments. LED Backlight, TN panel, #FFFFFF LED Backlight, TN Panel, #FF0000. Note the blue that comes through, though camera had trouble focusing on it. I've also seen this on my laptop, which has no adjustments obviously. CCFL Backlight TN Panel, #FFFFFF. Note the breaks in the spectrum. CCFL Backlight, TN Panel #FF0000. The blue light is still there, but less of it. Both red pictures the camera had trouble capturing the blue light. Ill work on that. I promise this weekend I'll work on this and get you lots of different test pics on different screens using more colors and hopefully more consistent pictures. I'll also add lights to it and test each of these screens with flux as well as different settings if I can. Ill also filter it with some blue light glasses, see what happens As for the laptop being less of a strain on my eyes even on max brightness, next to a ccfl monitor it's clear it is a lot harder to focus on (I've never had thees in the same room really, I dont use the old monitors much anymore), BUT it's smaller than the other led monitors I have, and I think that has a lot to do with it. I did test it quickly, and it does put off a decent amount of blue light on pure red. I've noted my tendency to turn 2 of my monitors off in my 3 setup at the end of the day, and I'm going to take one of my 27 inch screens that really burn me and next time I watch a movie I'll put cardboard over part of it and see how it feels. I didn't think about this because I put the one laptop right next to my face on my chest in bed when I watch stuff on it, but im sure the actual amount of light is less. I've also noticed I keep one on high brightness at work, and the 27 inch screen next to it is way dimmer, but they seem equal as far as eye strain go with those settings. I'll experiment with this, itll be personal opinion of course, but I think I'd be able to tell since it strains my eyes so much. It's never so apparent at first but after a long day I can basically tell by looking. I discovered this all some years ago because I couldn't figure out why the fuck some screens were a strain and others were not. At first I had thought I was just on computers more than normal, but decreasing use between semesters of college didn't help. Sometimes, its was at the point that I wanted to zoom in to read, but I eventually noticed moving it to the old screen I had in my setup at the time I could read fine. I first thought it was because the new screen was too bright, but after adjustment it still strained me and I thought it was just the screen. Up to that point shit like "gaming glasses" had been overlooked as a gimmick to me, but on recommendation I got some cheapo blue light glasses with zero expectation and was very surprised when they help immensely, and more than flux. It was then that I looked up stuff related to it, I had also acquired more screens and noticed a pattern of when I used the glasses. This isn't nocebo as I had the problem and the pattern long before I assigned a reason, there's plenty of studies on this including one that came out last week about the mechanisms of the damage which made the front page of reddit. In addition, plenty mention backlights. https://utnews.utoledo.edu/index.php/08_08_2018/ut-chemists-discover-how-blue-light-speeds-blindness https://www.nature.com/articles/s41598-018-28254-8
  4. I was wrong about my current laptop, and well get to that its interesting. I'm misunderstanding screens, you're not understanding light. 2 visible lights appear to be a color when combined. Im trying to find what part of this are you not getting so I can provide a source. Here's a source for the next parts I will quote, it's about the mechanisms of visible blue light from LEDs damaging our eyes. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4734149/ You can produce two further apart wavelengths that are perceived as the color on the middle. This isn't about what our eyes see it as, but the actual wavelength inside the visible spectrum. This is important because Instead of producing the actual wavelength of a color, you can produce 2 wavelengths on opposite "extremes" of a color and get the same color, at least as we perceive it. Making yellow with red and green doesn't make a yellow wavelength, you still have the higher frequency green wavelengths hitting your eyes. This is how leds work, and why they produce more blue light. ..... All 3 lights, according to this source, look the same, but those are the different wavelengths they produce. Additive color. "Gaming" glasses subtract blue, so that's more like how combining paint or printer ink works. Sunglasses help to, but at that point its no different than lowering brightness a ton. Whats important relevant to eye damage is not the color we see, but the total amount of light our eyes receive in the smaller blue wavelength range, as it's those short waves that cause damage, just as UV light, to the left of this spectrum all the way down to 10nm causes damage to our eyes even though we dont see it. In a sense, LEDs fake colors by combining other colors. Also this is good to note Below this, this source talks about light our eyes receive in the non visible range being responsible for things like our circadian order. I have circadian rythem disorder, and my sleep cycles are never based on light very much, so the study of how visible and non visible blue light from leds affects sleep is not of much concern to me. I'd like to re-enforce the fact that mixing spectrums to make a visible color and producing the real wavelength is not the same thing. Think about the color magenta or colors close to it. It's technically a Non-spectral color, and it doesn't have a wavelength, it's not technically a real color. It's really just our perception of the combination of red and blue, which are on the opposite ends of the spectrum. In the same way, if you produce a red wavelength and green wavelength and combine them, we see yellow, but ti's just two wavelengths superimposed. It's not actually a yellow wavelength on the spectrum. Back to screens, because I'm way wrong on what backlights were offered and how commonly, and I should start saying led burn and not IPS burn for sure. I've mentioned the acer predator is LED. I forgot I had the MNs in my signature, I looked on my amazon history for that one. I've mentioned that it is indeed more comfortable than say the asus ones on the one im using now next to my laptop, but still burns me. Same as the PS TV, sans the glossy plastic panel seriously fuck that thing. The PLS and AVHA panels I mentioned are the korean monitors I may have in my signature. I think I'm wrong about how common IPS CCFL and LED TN are. Almost every laptop I still own I know are CCFL, but this one, the dell precision (I have two of these actually), is a 2011, and I assumed it was because TN. I just assumed laptops still had inverters on the low end, but I was wrong. I looked it up (m4600) and it was offed with an LED-IPS screen as well, so popping the front panel off, it has no inverter I see. I've always considered this laptop intensely bright on white, but it doesn't burn me if you know what I mean, and while I never game on it or anything I have watched some movies and used to read a lot at night on it no problem. I used flux sometimes, but it still is not the same, even at high brightness, and I was using it because I was already fatigued from using a screen all day. I wonder why that is, because it's clearly lED backlight and its seriously one of the only screens that doesn't strain my eyes quickly, and right now its up very bright compared to the monitor next to it. Im sure if I sit it next to a ccfl I can tell the difference, but its really not that bad for some reason. There appears to be a spot for an inverter, and I think some precisions from slightly before this had one. I know I've replaced them on other precisions with the same body and newer laptops than this, but keep in mind for the longest time people advertised "beautiful hd panels" and gave tn 1366x768 screen, the lowest resolution panel in that size you can buy, and I bet it's a combination of cheap and old stock that kept these in use for a few more years. I fixed a lot of cheap laptops. Some had inverters, some didn't like I know some of the cheap ass hps from this time dropped them, and I really didn't think about that. I remember not liking that, as those early cheap silver plastic body hps bunred inverters like no ones business, and I was disappointed I stopped getting a steady stream of them to repair all of the time. The other screens Im not home for, but most if not all Im pretty sure were bought before LED-LCD was even a common thing. The 23" LG one has been fixed a couple of times before (it just wants to retire) and I know the ccfl back-light is dying in it, you can see it sometimes flicker like a dying tube light. The dell ones, some are older 5:4 ones, one is a 17 inch 1440x900 one, silver bezel not much newer than the 5:4 ones. They're all very thick and more power hungry than newer led based screens, hotter too. The rest of my monitors are even older, a couple extra 5:4 ones (seriously every business had them) and some like 1024x768 ones. I even have an e-machines lcd somewhere...shudder at that thought. I bought that one new. I assume the crts mns dont matter? I've just looked up an old latitude I had, and it lists LED for all options, but I know it has an inverter and I found parts for it. e6400 P/N MT581, I'll get back to you on that. I've always been a desktop guy until college and work, so I never really bought laptops new, had a ton from fixing them and business dumps. Aside from the macbook, the 2011 precisions are my newest laptop. Out of all of the screens listed, my total viewtime is highest on the korean monitors (they are at my place of work now) and the 23" lg. The LG was my primary monitor for consoles for years, and it still gets some use. It has to be 10 years old at this point. There is also a CCFL backlit tv I gave a way a a couple of weeks ago, it was really old and 1366x768. Wouldn't even interpret a 1080 signal. Yes it was easy on my eyes but holy crap it was a bad tv.
  5. An LED light at 6504k would put off more blue light than a ccfl at the same temperature, that's the entire point. CCFL IPS screens are very rare, and really only early IPS screens had this. In fact, the only ones I know of are from when IPS was new and they were still 1000$ or more for a screen. For TN panels with LED backlights, it's less rare, but it's recent. All TN screens I own except a newer 144hz screen I bought 2 years ago and another well mention later are CCFL. This said, every single laptop I've come across with a TN screen is CCFL. Granted, I stopped fixed laptops a few years ago and I'm sure LED TN on a laptop exists, but I was still doing it when were were getting a lot of ips laptops. The one I'm typing on is ccfl. It can be a surprisingly compact technology, and the inverts are about the size of a pencil. Yes I've made a generalization, and that's why I pointed out the types of backlights specifically in a later post, because I had made the assumption that anyone who moved from TN to something else went from CCFL to LED, as most people didn't buy a newer TN monitor within the past few years when IPS is so cheap. Im not home so I cant give mns, but I own the following screens that burn my eyes. Feel free to ask m/ns for any of these and Ill get it later 3 24" Asus IPS screens An LG ultrawide, ips A 27 inch samsung PLS panel A 27 inch (LG?) AHVA panel A PlayStation TV (well get back to this one, its important) acer XB241H , LED, TN, burns me less but still does. My TV My early 2018 macbook Phones I guess These dont burn my eyes 3 17 inch older dell TN monitors somewhat middle aged dell TN screen. This one has a blue tint I dont like, but is CCFL and doesn't burn, just irritates. LG tn 23" monitor that I got in around 2008 and still use daily 2 dell precision laptops with matte 1080p screens, TN. Using one now. Bright as hell, doesn't bother me. A few other laptops I dont use much, a few dell latitudes, some old hp, etc 2 CRT security tvs A smaller CRT TV (I dont use this much) A crt dell monitor (I play older games on) Any old devices and monitors I used to use but no longer do- a shelf in the garage with screens, shit like a psp lol The playstation TV (no, I didn't buy one new, I got it like this year for 80$) is important because it's one of the only examples of older LED TN monitors I can point to. This was typical of 3d screens, I can only assume for the flickering it does, or "240Hz" as the box calls it. It does burn me, but not nearly as bad as IPS screens. I'd say it's like an IPS screen with flux on low. Same goes for my TN acer 144Hz screen. Also the PS tv is stupid, dont buy one, not even for 80$. So yes you're right I can't make that generalization, but that's why I did, and I don't have a complete misunderstanding of how they work. I will still argue most people would have ccfl tn panels, and IPS eye strain is more talked about among pc users as it is since a lot of people got their first LED backlight in the form of an IPS screen. Literally in my house I have such a huge sample size that I figured a pattern and looked into why I was irritated by my IPS or similar screens more, and it's the LED backlight. To make an LED backlight that wouldn't have excessive UV light, it would basically be warm-orange color. Some leds that are closer to soft white than daylight still put off a lot of blue. LEDs in monitors are pure white, a lot of blue. I know minor differences can be made up (color temp settings wouldn't exist otherwise) but I have to assume the base light cannot be really warm, like 2700k? That's stupid warm, there's no way that would work right? This is also where the TN being a bit less burn than IPS regardless of backlight type comes in. Washed out, warmer colors change the backlight a little. Same effect with flux though, and the LED light is still there, making all that blue A CFL bulb of the same temperature would likely have to be much brighter to give the same amount of blue light off, particularly in the area close to the UV side. Notice how there's 2 focused spikes closer to the middle and less in the edges. The blue light, as far as total quantity not the highest spike, has more output in the 500nm is range, light blue. I dont know what temp of bulb this graph is for, but it's a fairly similar story across all temps for CFL, with it shifted a bit. So again, no. The blue light is still there, it still penetrates your eyes more, and still carries the risk of macular degeneration. Light on the blue side of the spectrum interacts with your eyes in a different way completely, and the shorter wavelength penetrates more, and I'm not talking about UV, visible blue light does this. This is additive color, not subtractive color. The red and the green wavelengths in this picture dont stop existing, this isn't mixing paint or something. How the backlight makes the color is important, not just the pretty much even R-G-B from the subpixels. This is why studies on the effects of leds and blue light on your eyes often specifically mention led tvs. This is also why flux can help, but doesn't solve the problem like glasses do.
  6. No, not really. Did you not read my post? It's the difference between LED and CCFL backlights. The cool temp leds used in the backlights put of way more blue light. The CCFL bulbs, even the ones with a cool temp, not so much. Its just how it is. The variance you see in eye strain monitor to monitor with LED backlights is mostly brightness and flicker- being that if you are sensitive to the flicker from ccfl lights- especially some do pretty bad with brightness not at 100%- you might be better off with LED. PWM flicker is at a much higher rate with LEDs I think, at least with regular lights they are. I've never really looked into that since I'm not bothered by flicker. There are some color temp variances with the backlights, but mostly anything that would give you significantly less blue light would also have a bad picture. Since I'm sensitive to blue light, all IPS screens, since they have led backlights, are a strain. This of course applies to anything with that type of backlight, I have an AHVA panel that does the same to me. Actually that one is really bad because it's brighter than the sun at full brightness, I think I use it at less than 50%.
  7. This is not right. IPS eye strain is a thing. IPS screens put off way more blue light than a TN panel. I almost never use a screen with the lights off. My office at home and at work is very bright. The only time I'm likely to do anything in the dark is games or watching stuff, both of which I make sure to do on tn and have no problem. This is the entire reason people use flux or wear those 'gaming glasses'. Blue light isn't good for your eyes and some people are much more sensitive than others. I used to think I never had problems with it, but I eventually found out my line is somewhere between CCFL and LED lol. If I do filtering glasses, I have no problem with it. Flux helps too, but even when putting off orangeish colors ips still puts off a lot of blue so glasses re the best solution. Blue light goes beyond the monitor too. I've had people tell me they got rid of blue led ambient light in their room for this reason or simply had to switch to soft white color temperature. As I've mentioned earlier in this thread I cannot stand daylight bulbs, so all of the cfl and LED bulbs I eventually switched to are soft white. Anything really 5000k or beyond I do not like. I prefer less than 3000k. Unfortunately, most LEDs are daylight or more blue. First couple gens of leds did have a blue tint, but even today most put of a lot of blue because a more true white is what a lot of people want for some reason. All leds give of more blue light than other shades. The amount of blue light proportion to the total light is on the up for everyone, and we're being exposed to more and more blue light. My TN screens use an LCD backlight, and this is what makes them better on my eyes. The CCFL backlight is much easier on my eyes, even ones that flicker (some do have a sensitivity to the flicker) LED based backlights have a huge amount of blue light, as a warm white led would not make for a good picture. The CCFL backlight would look like fluorescent graph, and they put off very intense spikes of specific wavelengths depending on temperature. I dont like daylight CFL bulbs, but they irritate me far less as well. This is why TN hurts my eyes less. IPS screens are not only LED backlit with leds on the cool side, they have a more color accurate picture as well, both factors blasting me with blue light. Flux only solves the later, but not the backlight. Blue light affect peoples eyes to varying degrees, but its universally not-a-good-thing-in-excess. It also is more likely to affect things like sleep. 10 years ago, my whole house was incandescent, all of my devices were ccfl, and even the street lights were like sodium vapor lights and other orange light types, and there was no problem. Now as soon as my eyes hit led street lights, they start to adjust like I'm driving through bright daylight, and that's not a good thing. So all that said if you ever experience darkening or eye strain, I encourage you to experiment with both the type of screen you use and the lighting around you. Myself I'm getting my eyes checked out soon, as I think I need my first pair of glasses, and I might get ones with a slight uv filter, not like yellow like the glasses I wear to reduce eye strain, but take a bit of the edge off. @dalekphalm for comment
  8. I mean bad for how my eyes react using them, darkening blurring is more or less a non problem compared to IPS. Bad in general? Yah probably. They do give me headaches sometimes. Not a good sign. I dont really use crts much anymore aside from retro games so not really much of an issue. I pretty much avoid CRT tvs in favor of crt monitors for the most part now too since unlike the monitors they put off a whine that's the same pitch as my tinnitus. Double headache.
  9. I dont think you understand the difference between TN and IPS for me. I can use a TN screen from the time I wake up until I drop and I will be pretty much fine, IPS I will make it 8-10 hours before wanting to zoom stuff in or use flux or something else. It literally feels like my eyes are burning. Laptop Im typing it on now, TN matte panel, fine for me 100%. Flux does a decent job for me with an IPS screen (still puts off a lot of blue even with flux), but yellow glasses solve the problem more directly. It's also been proven that yes, blue light is bad very bad for your eyes. Screens are bad too, just not the the extent that people say, and reading a book has the same effect.
  10. crts aren't bad, but I dont like the flicker after a while. I've been using TN LCDs since idk I think my first one was 800x600. I held on to TN as a primary screen until like 2014 I think, still had one on my main desktop until 2016. I know IPS doesn't cause the problem, but it does have enough blue light to trigger the eye strain for me. So I get to join that group of people with flux installed, yellow glasses, and grumbling about streetlights switching to daylight bulbs.
  11. My prediction: Wells Fargo will fail some more, then eventually be simply renamed.

  14. Electronics Ru-furbishing Business?

    Soldering tools BGA station, infrared if you can. Other ones are just a glorified heat gun on a stick, not worth it unless you can get it cheap. (tons of stencils too) A reflow oven. You can get cheap a starter by taking a toaster oven and making your own temp controller with an arduino or something. Those wont be big enough for some boards though. A parts stockpile, you'll know what you need as you get some experience. Stuff like game consoles is easy, laptops and phones are harder Insurance. Gonna need that. You're gonna want security bits and regular bits that are LONG, meaning the bit extends enough to reach into holes without hitting the screwdriver.
