Embodiment Construction

[0012] see figure 1 , is a schematic cross-sectional view of a curved display screen 10, including a front polarizer 20, a front glass plate 30, a color filter film 40, a liquid crystal layer 50, a thin film transistor matrix 60 composed of a plurality of thin film transistors (TFT) 62, and a rear glass plate 70 and rear polarizer 80.

[0013] The color filter film 40 , the liquid crystal layer 50 , and the TFT matrix 60 are packaged between the front glass plate 30 and the rear glass plate 70 , and the liquid crystal layer 50 is located between the color filter film 40 and the TFT matrix 60 . The front polarizer 20 and the rear polarizer 80 are attached to the outer sides of the front glass plate 30 and the rear glass plate 70 respectively.

[0014] The front glass plate 30, the rear glass plate 70, the front polarizer 20, and the rear polarizer 80 are all curved surface structures. Shaped by stretching. When the two glass plates are stretched, the area occupied by the thi...

Abstract

The invention discloses a curved display screen, which comprises a front polarizer, a front curved glass plate, a color filter, a liquid crystal layer, a thin film transistor matrix consisting of a plurality of thin film transistors, a rear curved glass plate and a rear polarizer, wherein the color filter, the liquid crystal layer and the thin film transistor matrix are packaged between the front and rear glass plates; the liquid crystal layer is positioned between the color filter and the thin film transistor matrix; the front polarizer is attached to the outside of the front glass plate, and the rear polarizer is attached to the outside of the rear glass plate; each of the front and rear glass plates is formed by extending a flat glass plate; and the thin film transistors are subjected to pre-compression before the extension of the front and rear glass plates, and a compression ratio of the pre-compression is determined to be an inverse ratio of the extension ratio according to an extension ratio of each thin film transistor after the extension of the flat glass plates to the curved glass plates. The invention also provides a method for manufacturing the curved display screen.

Description

technical field [0001] The invention relates to a display screen, in particular to a curved display screen and a method for manufacturing the curved display screen. Background technique [0002] The current display screen is a planar structure. With the increase of outdoor advertisements, it is more and more common to hang the display screen outside the building for advertising. However, the planar display screen is generally embedded on the flat outer wall. , it is not suitable for some buildings with large radians. In addition, the angle of view of the advertisement displayed on the flat-panel display is also small. Contents of the invention [0003] In view of this, it is necessary to provide a curved display screen and a method for manufacturing the curved display screen. [0004] A curved display screen, the curved display screen includes a front polarizer, a curved front glass plate, a color filter film, a liquid crystal layer, a thin film transistor matrix composed...
