Abstract: A half-tone liquid crystal display panel having half-tone pixels (50), each comprising a plurality of sub-pixels including first (31) and second (33) sub-pixels. Activation voltage is supplied to the first sub-pixel (31) from a TFT switch (18) and to the second sub-pixel (33) from the TFT switch through a coupling capacitor (39, 42). The second sub-pixel includes a storage capacitor (51, 53). Sensitivity of the activation voltage applied to the second sub-pixel resulting from capacitance non-uniformity across the panel is reduced by forming the coupling capacitor (39, 42) and the storage capacitor (51, 53) of the second sub-pixel with the same depositions utilizing a common dielectric layer (41). The capacitance (53) of the storage capacitor of the second sub-pixel is designed large compared to the capacitance (36) of the second sub-pixel.

Abstract translation: 一种半色调液晶显示面板，其具有半色调像素（50），每个半色调像素包括多个子像素，包括第一（31）和第二（33）子像素。 激活电压通过耦合电容器（39,42）从TFT开关（18）提供给第一子像素（31），并从TFT开关提供给第二子像素（33）。 第二子像素包括存储电容器（51,53）。 通过与第二子像素的耦合电容器（39,42）和辅助电容器（51,53）形成耦合电容器（39,42），使得通过面板的电容不均匀性产生的施加到第二子像素的激活电压的灵敏度被降低， 使用公共介电层（41）的相同沉积。 与第二子像素的电容（36）相比，第二子像素的存储电容器的电容（53）被设计得很大。
