    IPS vs AH-IPS

    These below were all developed by Hitachi Super TFT (IPS) - 1996 Wide viewing angle 100/100 Base level Most panels also support true 8-bit per channel color. These improvements came at the cost of a slower response time, initially about 50 ms. IPS panels were also extremely expensive. Super-IPS (S-IPS) - 1998 has all the benefits of IPS technology with the addition of improved pixel refresh timing. Advanced Super-IPS (AS-IPS) - 2002 Improves substantially on the contrast ratio of traditional S-IPS panels to the point where they are second only to some S-PVAs. IPS-Provectus (IPS-Pro) - 2004 The latest panel from IPS Alpha Technology with a wider color gamut and contrast ratio matching PVA and ASV displays without off-angle glowing. IPS alpha (IPS-Pro) - 2008 High contrast ratio Next generation of IPS-Pro IPS alpha next gen (IPS-Pro) - 2010 High contrast ratio Technology transfer from Hitachi to Panasonic These below were all developed by LG Horizontal IPS (H-IPS) - 2007 Improves contrast ratio by twisting electrode plane layout. Also introduces an optional Advanced True White polarizing film from NEC, to make white look more natural. This is used in professional/photography LCDs. Enhanced IPS (E-IPS) - 2009 Wider aperture for light transmission, enabling the use of lower-power, cheaper backlights. Improves diagonal viewing angle and further reduce response time to 5ms. Professional IPS (P-IPS) - 2010 Offer 1.07 billion colours. More possible orientations per sub-pixel (1024 as opposed to 256) and produces a better true colour depth. Advanced High Performance IPS (AH-IPS) - 2011 Improved colour accuracy, increased resolution and PPI, and greater light transmission for lower power consumption
