Problems solved by technology

Especially when the color filter is pixelated in the liquid crystal-on-silicon panel (patterned color filter is made on the chip), the DC charge may be non-uniformly distributed on the built-in color filter, resulting in internal electric field Inhomogeneity, so that the rotation of the liquid crystal molecules is not complete, causing defects such as water ripples (mura)

Abstract

For a panel of a silicon liquid crystal display device, a colorful light filter which is arranged inside is unevenly accumulated and distributed with residual direct current charges, so the inner electric field which controls the arrangement of liquid crystal molecules is not even. In order to reduce the residual direct current charges to make the inner electric field even, the present invention provides a panel structure of a display device, which comprises a plurality of shield layers, and the shield layers are used for surrounding the corresponding colorful light filters; wherein, each shield layer is communicated with a corresponding pixel electrode by wires.

Description

technical field [0001] The invention relates to a display panel structure, and in particular to a liquid crystal on silicon (LCoS) panel structure. Background technique [0002] Residual DC charge is an unresolved problem in liquid crystal display devices due to the accumulation of ionic components on the pixels of the device. For example, in existing twisted nematic liquid crystal display (LCD) devices, residual DC charge accumulates at the alignment layer interface of each pixel, and the resulting residual DC voltage causes a liquid crystal configuration across the pixel and between the transparent electrode. Causes after-image phenomenon. Methods for solving this problem, such as using a low-resistance alignment layer, have been disclosed, for example, in Japanese Patent Application Laid-Open No. 8-54631. [0003] For liquid crystal on silicon, the problem of residual DC charge may be more serious. Since different types of electrodes (eg, indium tin oxide (ITO) transpa...
