Liquid crystal display module with LED lamp located at outside of backboard

Abstract

The invention discloses a liquid crystal display module with an LED lamp located at outside of a backboard. The liquid crystal display module comprises a display mechanism, a heat dissipation mechanism, a retroreflector and the LED lamp; the display mechanism comprises the backboard, a reflector, a light guide plate, an optical film material, a plastic frame, a liquid crystal display panel and anexternal frame; the reflector is mounted on the backboard, the light guide plate is mounted over the reflector, the optical film material is mounted over the light guide plate, the plastic frame is arranged on the backboard in the form of sleeving, the liquid crystal display panel is mounted on the plastic frame and located over the optical film material, the external frame is arranged on the plastic frame in the form of sleeving; a light guide through hole is arranged at a position, corresponding to the light guide plate, on the side edge of the backboard; a mounting groove is arranged on theplastic frame, the reflector is mounted in the mounting groove in the form of corresponding to a position of the light guide through hole; the heat dissipation mechanism comprises a heat dissipationblock and a plurality of mounting columns, the heat dissipation block is mounted in the mounting groove and located under the retroreflector, the heat dissipation block is provided with a heat dissipation slot opening downwards, and the mounting columns are mounted in the heat dissipation slot; and the LED lamp is mounted over the heat dissipation block. The liquid crystal display module with theLED lamp located at outside of the backboard has the advantages of steady structure, excellent heat dissipation effect, convenience in use, and so on.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a liquid crystal display module with LED lamps located outside the back plate. Background technique [0002] In modern society, liquid crystal display technology has been widely used. Liquid crystal display modules have many advantages such as thin body and power saving, and are widely used in devices such as handheld computers, computer screens, and notebook screens. 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 cooperate to fix the liquid crystal display 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 panel and is difficult to dissipate effectively. Continuous high temperature will not only affect the normal operation of the light ba...

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
