Liquid crystal display module and liquid crystal display device

Abstract

The invention discloses a liquid crystal display module. The liquid crystal display module comprises a liquid crystal display screen and a backlight module. The backlight module comprises a first surface and a second surface opposite to the first surface, and the liquid crystal display screen is attached to the first surface of the backlight module. The liquid crystal display screen comprises a lower polarizer, a CF screen, a TFT screen and an upper polarizer, wherein the lower polarizer, the CF screen, the TFT screen and the upper polarizer are sequentially laminated. The backlight module comprises an iron frame, a rubber frame, a reflecting film, a light guide plate, an optical film material and lightproof rubber, wherein the reflecting film, the light guide plate, the optical film material and the lightproof rubber are sequentially laminated, and the liquid crystal display screen, the reflecting film, the light guide plate, the optical film material and the lightproof rubber are arranged inside the rubber frame; the iron frame is arranged outside the rubber frame, the rubber frame is provided with metal powder, and a magnetic thin film is arranged on the second surface of the backlight module. The invention further provides a liquid crystal display device with the liquid crystal display module. By means of the liquid crystal display module, deformation of the rubber frame in the temperature test can be avoided, the liquid crystal display module is easy to assemble, the corrugated problem of the film material can be solved, and the liquid crystal display module is further easy to repair.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display module and a liquid crystal display device. Background technique [0002] With the continuous development of electronic technology, liquid crystal display devices such as tablet computers are becoming more and more large-screen. For example, tablet computers have developed from 7 to 8 inches in the past to 10.1 to 12 inches now, and the size of the screen will continue to increase in the future. the trend of. [0003] All liquid crystal display devices include a liquid crystal display module. see figure 2 The traditional liquid crystal display module 200 usually includes a liquid crystal display 210 and a backlight module 220. The liquid crystal display 210 includes a lower polarizer 2101, a CF screen 2102, a TFT screen 2103, and an upper polarizer 2104 stacked in sequence. The backlight module The group 220 includes an iron frame 2201 , a plastic...

AI Technical Summary

Problems solved by technology

In the first solution, the iron frame 2201 and the plastic frame 2202 are fixed by buckles. Due to the design and manufacturing tolerances in practical applications, the plastic frame 2202 still has a certain deformation in the temperature test. It is verified by the test that there is still a film slight wrinkling of the film material; in the second solution, by adding double-sided adhesive 22011 on the iron frame 2201, the deformation of the plastic frame 2202 can be slightly prevented, and the problem of wrinkling of the film material can be partially solved, but this solution is difficult to repair. In addition, the double-sided The thickness of the glue 22011 is generally only 0.6-1mm, it is not easy to punch and stick, and it is easy to cause the backlight module 220 to be dirty
