Problems solved by technology

However, due to the semi-transmissive semi-reflective liquid crystal display panel of the double-gap design, the steps of making the dielectric layer 22 in the reflective area 181 must be added, which will not only increase the process time and cost, but also affect the yield. More importantly, the reflective The drop at the junction of the area 181 and the penetrating area 182 will also make the alignment of the liquid crystal molecules difficult, thereby reducing the display quality of the picture.
In addition, although the existing transflective liquid crystal display panel is designed with a single liquid crystal gap, the method is to use different control circuits to drive the reflective area and the transmissive area respectively, which not only increases the layout complexity of the array substrate, but also The driving method is also more complicated

Abstract

The semi-penetration semi-reflection LCD panel comprises: a couple of parallel substrates, a couple of polarizing pieces set on substrate surface respectively, and the macromolecular dispersion LC layer arranged between substrates. Wherein, the LC molecule can only generate reflection and penetration to incidence light when forcing voltage.

Description

technical field [0001] The invention relates to a semi-transmissive and semi-reflective liquid crystal display panel, in particular to a liquid crystal display panel in which the liquid crystal molecules have dual functions of penetration and reflection by using a network polymer. Background technique [0002] According to different sources of illumination light, liquid crystal displays can be divided into three types: transmissive, reflective, and transflective. The transmissive liquid crystal display usually has a backlight for generating light, and the light generated by the backlight passes through the liquid crystal panel to allow the user to watch the image display of the liquid crystal display. The reflective liquid crystal display is provided with a reflective electrode. When the reflective liquid crystal display displays a picture, the ambient light enters the liquid crystal display from the user's observation surface, and after entering the liquid crystal panel, th...
