Problems solved by technology

However, due to the uneven extrusion of the edge of the liquid crystal cell after bending, the hard birefringence of the glass panel, and the inconsistent deformation of the upper and lower surfaces, the brightness of the curved surface will be uneven, which will seriously affect the display effect of the curved liquid crystal display.

Abstract

The invention provides a curved liquid crystal display, comprising a liquid crystal display panel and a metal wire grid polarizer stacked on the liquid crystal display panel, the liquid crystal display panel includes a display surface, and the display surface includes a first display area and a first display area. A second display area connected to the first display area, the arc of the first display area is greater than the arc of the second display area; the surface of the metal wire grid polarizer is provided with several parallel and spaced wire grids, The metal wire grid polarizer includes a first polarizing area corresponding to the first display area and a second polarizing area corresponding to the second display area, and the wire grid duty ratio of the first polarizing area is smaller than that of the first polarizing area. The duty cycle of the wire grid in the two polarizing regions, wherein the duty cycle of the wire grid is the ratio of the width of one wire grid to the distance between two adjacent wire grids.

Description

technical field [0001] The invention relates to the technical field of display screens, in particular to a position-limiting thimble of a curved liquid crystal display and a curved liquid crystal display. Background technique [0002] As users have higher and higher requirements for the display effect of the display device and the diversified structure of the display screen, LCD curved surface display can give users a better experience visually, and is applied in the fields of vehicles, Mobile, TV, smart watches, etc. . In the existing LCD curved surface technology, the same aperture ratio and the same pixel design are generally adopted. The LCD display panel is formed into a box, and then the LCD display panel is bent to make a curved screen, so as to realize the curved surface display of the LCD display. However, due to the uneven extrusion of the edge of the liquid crystal cell after bending, the rigid birefringence of the glass panel, and the inconsistent deformation of...
