Abstract

High transmittance and excellent image quality are two crucial requirements for thin-film transistor liquid crystal displays (TFT-LCDs). This work presents a novel pixel structure utilizing a vertical alignment liquid crystal (VA-LC) to improve both transmittance and image quality. The new pixel structure, called TCL-pixel, features a unique transparent conducting layer (TCL) that constructs an electric field shielding layer and a large transparent storage capacitor, resulting in good stability and a large aperture ratio. The 55" 8 K product incorporating the TCL-pixel achieves high transmittance (3.87 %) and a high contrast ratio (5100:1), attributed to the large aperture ratio. Additionally, it exhibits negligible vertical cross talk (0.7 %), low color cross talk (3 ‰), low horizontal cross talk (JND 2.3), and enhanced variable refresh rate performance, confirming its good stability. Furthermore, the TCL-pixel demonstrates an improved viewing angle (CESI 0.03：65°) due to the multi-domain alignment produced by the transparent conducting layer.

高透光率液晶显示，图像质量优异

高透光率和优异的图像质量是薄膜晶体管液晶显示器（tft - lcd）的两个关键要求。本文提出了一种利用垂直对准液晶（VA-LC）的新型像素结构，以提高透光率和图像质量。这种新的像素结构被称为TCL-像素，它具有独特的透明导电层（TCL），它构建了电场屏蔽层和大型透明存储电容，从而具有良好的稳定性和大孔径比。采用tcl像素的55 ' 8 K产品具有高透光率（3.87 %）和高对比度（5100:1），这归功于大孔径比。此外，它具有可忽略的垂直串扰（0.7 %）、低彩色串扰（3 ‰）、低水平串扰（JND 2.3）和增强的可变刷新率性能，证实了其良好的稳定性。此外，由于透明导电层产生的多畴对准，tcl像素显示出改善的视角（CESI 0.03:65°）。
