Liquid crystal module (LCM)

Abstract

The invention provides a liquid crystal module (LCM), comprising a film on glass (FOG) liquid crystal display screen and a backlight module arranged on the back of the FOG liquid crystal display screen, wherein the backlight module comprises a light guide plate; a reflector plate is arranged on the back of the light guide plate; a light bar (LB) is arranged at an incident light port of the light guide plate; a metal back plate having functions of supporting and protecting is arranged on the back of the backlight module; a U-shaped lampshade formed by bending is arranged at the edge position of the metal back plate; the reflector plate, the light guide plate and the LB are connected into the lampshade in a clamping way; a layer of polyethylene terephthalate (PET) gasket is arranged between the FOG liquid crystal display screen and the outer surface of the U-shaped lampshade. Compared with the prior art, the LCM is provided with the U-shaped lampshade formed by bending the metal back plate, thus improving the utilization rate of light, increasing the brightness of the product by 8%, reducing the energy consumption of the product and saving the cost; furthermore, the mechanical strength of the whole product is improved, and the problems of screen breaking, integrated circuit (IC) breaking, and heat dissipation of an IC driven by a backlight LB and an FOG are synchronously solved.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to an LCM liquid crystal display module. Background technique [0002] LCM liquid crystal display replaces the traditional CRT cathode ray tube display because of its clear and delicate image, no flicker, no eye injury, no radiation, low power consumption, lighter and thinner, and many other advantages, and is favored by consumers. At present, it is widely used in electronic watches, mobile phones, PDAs, handheld game consoles, learning machines, GPS navigators, digital cameras, digital video cameras, computer monitors and televisions. It is also used in automotive, medical, military and other fields with high reliability requirements. Among them, the better structural design and construction technology can save more energy in daily applications, better protect the liquid crystal display from the influence and damage of the external environment, play a very active r...

AI Technical Summary

Problems solved by technology

[0003] At present, the traditional liquid crystal display module LCM (Liquid Crystal Module) generally includes FOG liquid crystal display 1, light guide plate 2, reflector 3, LB (light bar) 4, plastic frame 5 and back plate 6, light guide plate 2, Reflector 3, LB4 and plastic frame 5 form a backlight module, and the assembly method of the overall structure is as follows: figure 1 As shown, but the product strength of this structure is relatively weak, and the LCM is easily broken by external force or the IC is broken. Assembled together on the opposite side, when the LCM continues to light up, the driver IC of the LCD screen and the LB4 of the backlight will both heat up at the same time, because the backlight plastic frame 5 is made of PC material, and the thermal conductivity is relatively poor, so it is difficult to conduct heat out. The stability and life of the product have a very large impact

The backlight LB is assembled on the plastic frame 5 of the backlight. Because the plastic frame 5 is made of PC, the plastic frame 5 is easily deformed when the product is continuously lit or works in a high-temperature environment, and there are often bad phenomena such as explosion and light leakage that are harmful to the LCM liquid crystal display module. Group visual effects are affected; affect the reliability of the product
