AI Technical Summary

Problems solved by technology

This color display method of the existing liquid crystal screen is called spatial color technology in the industry, and has defects such as low color saturation, narrow color gamut, and low light transmittance.
[0003] In addition, due to the limitations of the thin film transistor (TFT) process, it is difficult to make the area of ​​the active matrix LCD screen large, and the existing indoor and outdoor large-area display screens can only be manufactured with light-emitting diodes (LEDs).
LED screens generally have the defects of high power consumption, uneven light emission and easy aging

Embodiment 1

[0031] Embodiment 1. A display screen suitable for display in public places

[0032] The main technical indicators of the display screen are:

[0033] The total display area is 1024mm×1024mm; the total number of pixels: 64×64=4096; the display area of ​​a single liquid crystal box: 128mm×128mm; the pixel pitch: 16mm; the pixel capacitor, capacitor switch and shift register are integrated in an area of ​​1mm× In a 1mm monocrystalline silicon chip, 32 pixel drive pins are arranged on the surface of the chip, the pin pitch is 0.1mm×0.1mm, and the pin area is 0.1mm×0.1mm.

[0034] The total manufacturing process is divided into two steps, display unit manufacturing and overall screen manufacturing. When manufacturing the display unit, the TN-type independent dot-matrix liquid crystal cell is first manufactured according to the conventional method, and the number of pixels in each liquid crystal cell is 8×8, a total of 64. The pixel pitch is 16mm, and each pixel is individually l...

Embodiment 2

[0036] Embodiment 2. A display screen suitable for displaying in a family room

[0037] The main technical indicators of the display screen are:

[0038] The total display area is 1536mm×864mm (69 inches); the total number of pixels is 1920×1080; the pixel pitch is 0.8mm; the driver chips are arranged at the upper and lower ends of the display area.

[0039] First, print parallel 0.5mm wide conductive lines on one side of a large glass plate with a thickness of 0.8mm, and cut it into glass strips with a width of 5mm and a length of 1000mm; stack 1920 of the above glass strips and paste them , Polished to make a glass plate, used as a glass plate of the liquid crystal box. Then, together with another plate glass printed with ITO film, a TN type liquid crystal cell is manufactured by a conventional method. In this way, a liquid crystal cell with a pixel size of 1920×1080 and a pixel pitch of 0.8mm is completed. After carrying out the high-density design of the single crystal ...

Abstract

The invention discloses an LCD television, in particular a field-sequential laser-activated color LCD flat-panel television, which comprises the production methods of an LCD, a digital interface circuit, a video interface circuit, an audio interface circuit, an infrared remote receiving circuit and a manual control circuit. The LCD comprises an LCD panel and a tricolor back lighting system. The tricolor back lighting system adopts three-color lasers, red (R), green (G) and blue (B), or common non-laser light sources. The invention also discloses a tricolor back lighting system, an LCD panel and a display which are used for the LCD television. The technical proposal of the invention can effectively increase image brightness displayed, and the color saturation and the color gamut of the pictures displayed by the LCD television.

Description

technical field [0001] The invention relates to video image display technology, in particular to a liquid crystal television, a three-color backlight lighting system, a liquid crystal display and a display. Background technique [0002] At present, the display screen of a liquid crystal flat-panel TV generally adopts an active matrix (Active Matrix, AM) liquid crystal screen, which drives and displays all the pixels in a picture by row scanning. Each pixel is further divided into three sub-pixels R, G, and B, and each sub-pixel surface is pasted with a tape (ie, a filter) of a corresponding color. The display drive circuit outputs the luminance values ​​of the three sub-pixels R, G, and B to the corresponding pixel electrodes to change the light transmittance of the liquid crystal between the electrodes. When the white light passes through, the dye on the tape absorbs other color light, and only passes through three kinds of light, red, green and blue, to realize color disp...
