So, my goal is to create a display that I can place flat on my desktop surface and possibly stick an IR or other touch enabling device on top of. It wouldn't be inlaid into the desk surface so it needs to be as thin as possible.
I was looking for laptop displays and the best options I could find from amazon/ebay were 17-21" 1920x1080 for decent prices.
$36.27 1920x1080 17.3" https://www.ebay.com/itm/Dell-Inspiron-17-5748-7746-AUO-17-3-1920x1080-FHD-LED-LCD-Panel-Screen-MM77H/132290188584
$48.91 1920x1080 17.3" https://www.amazon.com/dp/B01N9JEW5A/?coliid=I30JX6MBYGUIX7&colid=1VY2I8P14GPJP&psc=1&ref_=lv_ov_lig_dp_it
$25.49 1920x1080 21.5" https://www.amazon.com/dp/B07HPFWKQF/?coliid=I2RTUFZ5RRBRCZ&colid=1VY2I8P14GPJP&psc=0&ref_=lv_ov_lig_dp_it
I also found these options from alibaba but I'm not sure exactly what's up with these as they sound too good to be true almost.
21.5" 1920x1080 $20-50 https://www.alibaba.com/product-detail/21-5-inch-1920-1080-M215HGE_60750962243.html?spm=a2700.7724857.normalList.93.35e615ad5cRLrD
17.3" 3840x2160 $20-50 https://www.alibaba.com/product-detail/LED-Screen-Display-LCD-Panel-17_50040626565.html?spm=a2700.7724838.2017115.57.596bea16pKCIeR
(There are a lot more 380x2160 options on aliexpress but again, something seems fishy about those)
As far as connecting the laptop displays to my actual computer I know there are a ton of controller boards for ~$15 from ebay that I would get along with a panel.
I thought I might as well see if anybody here could provide some answers to some other questions I had as well.
Are there better places to get laptop displays for cheaper? (other than ebay, amazon, or alibaba)
Are there types of relatively inexpensive display panels that could be modded to use an HDMI/DP that would also be thin (and possibly larger).
Are there any 2560x1440 or even 3840x2160 laptop or other panels that would be available for decent prices? (still not sure about the alibaba option here)
Does anybody have an idea if a normal monitor panel could be modified to work similarly to laptop panels or do they usually have more stuff connected to the back that's non-removable?
Also, I don't have a super strict budget but if I could keep the total cost under or close to $100 that would be great. If there are larger/higher res displays that are priced well that might be a reason to increase the budget a little. (max display size would be about 32")
Thanks for any advice or help with this project
