Curved LCD panel structure

Abstract

The present invention provides a structure of a liquid crystal panel, which includes a TFT substrate (1), a CF substrate (3) opposite to the TFT substrate (1), spacers (5) arranged between the TFT substrate (1) and the CF substrate (3), a liquid crystal layer (7) disposed between the TFT substrate (1) and the CF substrate (3), and an enclosing sealant layer (9) arranged between and located along a periphery of the TFT substrate (1) and the CF substrate (3). In a curving direction of the curved liquid crystal panel, the CF substrate (3) includes middle zone (31) and two side edge zones (33) at two opposite sides of the middle zone. The middle zone (31) bears a stress greater than stresses born by the two side edge zones (33). The spacers (51) that are located in the middle zone (31) are arranged to bear a stress that is greater than stresses born by the spacers (53) that are located in the two side edge zones (33) so as to maintain a constant distance between the CF substrate (3) and the TFT substrate (1) and achieve the consistency of cell thickness in the entirety of the curved liquid crystal panel.

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 FilmTransistor Array Substrate, TFT Array Substrate), a color filter substrate (ColorFilter, CF), and a liquid crystal layer (Liquid Crystal) arranged between the two substrates. Layer), its working principle is to control the rotation of liquid cryst...

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
