Front K860i has brought us a new machine out of the box and evaluation, in the course of experience, the phone screen displays made a profound impression. From Lenovo official parameters, K860i uses AH-IPS (3 generation) screen, resolution up to 1280 * 720, screen brightness, 450nit, contrast is 1000:1, color saturation is 72%, using standard RGB pixel arrangement, but the angle up to 178 ° viewing angle. Prior to the K860i, although there are a variety of products made of AH-IPS material of the screen, but not many information, question as to how this material has characteristic? Might as well about science.
AH-IPS known as the Advanced High Performance In-Plane Switching, that is, “high resolution hard screen”, which is being developed by LG Display company applied to the advanced LCD technology for smartphones. The technology to high color accuracy, high resolution and good energy-saving characteristics known. Jack Spade iPhone 5 case
In the test of power consumption in comparison with AMOLED, AH-IPS power has always been a constant in the 624mW of the screen, while Samsung’s Super AMOLED PLUS screen 1130mW, almost twice times the AH-IPS screen. Of course, this does not mean that mobile phones overall battery life will improve for twice times, here is the data is only for reference.
Color characteristics, AH-IPS Smartphone is used to color accuracy (Color Accuracy) and color uniformity of color properties take full advantage. AMOLED in a dark color, contrast, and color gamut (Color Gamut) dominant in the two indicators. AMOLED style is gorgeous, but not real, and AH-IPS is relatively closer to the true color. Data does not explain everything, of course, many users love the gorgeous AMOLED screen effect, regardless of the parameter.

Image display quality, the AH-IPS displays an image more clear and natural, in light of the color contrast (Contrast), clarity (Sharpness), particularly on the aspects of readability and overall picture quality. Still has the advantage of wide viewing angle screen viewing angle 178 °/178 ° visual range.
Back to Lenovo K860i top, intuitive experience, we feel that the screen’s color temperature is too warm, and millet 2 results looked, but not as obvious as m 2; and Samsung Amoled screen of cool effects is distinct from and vivo X1 cold white contrast, contrast is also apparent. Overall, this screen the effect is relatively modest, slightly warm tones in daily reading in applications such as Internet, eyes not fatigue, for more wide range of users.
Other than the addition to Lenovo K860/K860i, LG screen for its variety of models are made of AH-IPS material, such as the LG Optimus 4X HD. AH-IPS as an extension of IPS products, will directly compete with Samsung’s AMOLED screen. Jack Spade iPhone case
