We have developed a new reverse dispersion retardation film with a thickness of 4 μm for IPS panels, which achieves excellent viewing angle performance, notably for oblique contrast ratio and color. HDR-IPS panels applied this reverse retardation film could achieve a significant improvement of the halo viewing from oblique angle.

研发反向色散液晶膜以改善高动态范围LCD的“光晕”

我们为IPS面板开发了厚度为4μm的新型反向色散延迟膜，该膜具有出色的视角性能，尤其是斜对比度和色彩方面。应用了这种反向延迟膜的HDR-IPS面板可以显着改善从倾斜角度观看的光环。
