Curved liquid crystal panel structure

Abstract

The invention provides a curved liquid crystal panel structure, which comprises a TFT base plate (1), a CF base plate (3), spacing objects (5), a liquid crystal layer (7) and a sealing glue layer (9), wherein the CF base plate (3) is in arrangement corresponding to the TFT base plate, the spacing objects (5) are arranged between the TFT base plate (1) and the CF base plate (3), the liquid crystal layer (7) is arranged between the TFT base plate (1) and the CF base plate (3), the sealing glue layer (9) is arranged between the TFT base plate (1) and the CF base plate (3) and is positioned at the edge, in the bending direction of a curved liquid crystal panel, the CF base plate (3) is provided with a middle region (31) and two side regions (33) positioned at two sides of the middle region, the stress born by the middle region (31) is greater than that born by the two side regions (33), and the spacing object (51) positioned in the middle region (51) is set to be capable of bearing higher stress than the spacing object (53) positioned at two side regions (33), so the equal gap is maintained between the CF base plate (3) and the FT base plate (1), and the integral box thickness consistency of the curved liquid crystal panel is ensured.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a curved liquid crystal panel structure. Background technique [0002] A liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as a thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or laptop screen, etc. [0003] Generally, a liquid crystal display device includes a housing, a liquid crystal panel disposed in the housing, and a backlight module disposed in the housing. Among them, the structure of the liquid crystal panel is mainly composed of a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), a color filter substrate (Color Filter, CF), and a liquid crystal layer ( Liquid Crystal Layer), its working principle is to control the rotation of liquid crystal molecules in the liquid crystal ...

Problems solved by technology

The spacer 300 is arranged between the TFT substrate 100 and the CF substrate 200 in the manner of equal height, equal density, equal CD (Critical Dimension) value, that is, equal size. The curved TFT substrate 100 and the CF substrate 200 will slide relative to each other, and the curved liquid crystal panel will generate left and right sliding stress with the center as the base point, and the stress will gradually decrease from the center to both sides. At the same time, the TFT substrate 100 The stress of mutual extrusion with the CF substrate 200 also gradually decreases from the center to both sides, and the stress on the middle area of ​​the curved liquid crystal panel is greater than that on the two sides, but the spacer 300 has the same height, the same density, and the same CD value. The method is set to cause the deformation of the middle area of ​​the curved liquid crystal panel to be greater than the deformation of the two sides, so that the cell thickness of the middle area is smaller than that of the two sides, resulting in uneven distribution of liquid crystal layer thickness, and the difference between the middle area and the two sides The light transmittance and response time are inconsistent, resulting in blurred images displayed on the curved LCD panel and a decrease in optical quality
