Novel liquid crystal display module with cooling block

Abstract

The invention discloses a novel liquid crystal display module with a cooling block. The novel liquid crystal display module comprises a backboard, a reflector, a light guide plate, an optical film material, a plastic frame, a liquid crystal display panel, an outer frame, a cooling device and an LED (light-emitting diode) lamp strip, the reflector is mounted on the backboard, the light guide plateis arranged on the upper portion of the reflector, the optical film material is arranged on the upper portion of the light guide plate, the plastic frame is arranged on the backboard in a sleeving manner, the liquid crystal display panel is mounted on the plastic frame and positioned above the optical film material, the outer frame is arranged on the plastic frame in a sleeving manner, the coolingdevice is mounted between the side edge of the backboard and the plastic frame and comprises the cooling block and a plurality of cooling plates, the cooling block is abutted to the backboard, the cooling plates are mounted on one side, far away from the backboard, of the cooling block and abutted to the plastic frame, a light guide through hole is formed in the side edge of the backboard and corresponds to the light guide plate, and a mounting groove is formed in the cooling block and corresponds to the light guide through hole. The novel liquid crystal display module is convenient to use and excellent in cooling effect.

Description

Technical field [0001] The present invention relates to the technical field of liquid crystal display, in particular to a novel liquid crystal display module containing a heat dissipation block. Background technique [0002] In modern society, liquid crystal display technology has been widely used. The liquid crystal display module has many advantages such as thin body and power saving, and is widely used in handheld computers, computer screens and notebook screens. In the prior art, the LED light bar is placed on the inner side of the back plate, and the heat of the LED light bar is dissipated through thermal conduction. The outer frame and the plastic frame cooperate to fix the liquid crystal display panel, which will generate a lot of heat when the LED light bar is working. The heat is concentrated on the inside of the back plate and is difficult to effectively dissipate. The continuous high temperature will not only affect the normal operation of the light bar, but also easil...

AI Technical Summary

Problems solved by technology

In the prior art, the LED light bar is placed inside the back panel, and the heat of the LED light bar is dissipated through heat conduction, and the outer frame and the plastic frame are fixed to fix the LCD panel, and a large amount of heat will be generated when the LED light bar is working. , the heat is concentrated on the inner side of the back plate and it is difficult to dissipate effectively. The continuous high temperature will not only affect the normal operation of the light bar, but also easily cause the light guide plate to expand due to heat, which will seriously affect the overall use effect and life of the LCD module. Therefore, the display module still exists. a lot of room for improvement
