Problems solved by technology

[0003] However, in the curved liquid crystal display, since the curved liquid crystal display is curved, for the user's sight, the phase retardation (retardation) of the part of the liquid crystal layer in the center of the display screen is different from that of the part of the liquid crystal layer on both sides of the display screen. Different amounts of phase retardation lead to abnormal display of curved liquid crystal displays, such as yellowing on both sides of an all-white screen, light leakage on both sides of an all-black screen, etc.

Abstract

The curved display curved along an axis as curvature centerline is provided. The curved display includes a first substrate, data lines, scan lines, active devices, pixel electrodes, a second substrate and a liquid crystal layer. Each of the pixel electrodes has a first keel, a second keel and branches electrically connected to each other. A pixel region which a pixel electrode located in is divided into a first domain, a second domain, a third domain and a fourth domain having different liquid crystal alignment orientations. The pixel electrode includes a first pixel electrode and a second pixel electrode respectively located in two sides of the axis. A sum of areas of branches of a first domain and a fourth domain of the first pixel electrode is a1. A sum of areas of branches of a second domain and a third domain of the first pixel electrode is b1. A sum of areas of branches of a first domain and a fourth domain of the second pixel electrode is a2. A sum of areas of branches of a second domain and a third domain of the second pixel electrode is b2. (a1 / b1) and (a2 / b2) are different.

Description

technical field [0001] The present invention relates to a display, and in particular to a curved display. Background technique [0002] When the user watches the flat-panel display, the distance from the center of the display screen of the flat-panel display to the user is not equal to the distance from the two sides of the display screen to the user, resulting in distorted images viewed by the user. Therefore, curved displays have been proposed. When the user watches the curved display, since the distance from the center of the display screen of the curved display to the user is close to the distance from the sides of the display screen of the curved display to the user, the images viewed by the user can be more realistic and reduce viewing fatigue. [0003] However, in the curved liquid crystal display, since the curved liquid crystal display is curved, for the user's sight, the phase retardation (retardation) of the part of the liquid crystal layer in the center of the ...
