Practical liquid crystal display module

Abstract

The invention discloses a practical liquid crystal display module, which comprises a back plate, a reflector, a light guide plate, an optical film, a plastic frame, a liquid crystal display panel, anouter frame, a reflecting mirror, a heat radiating block and an LED light strip. The reflector is mounted on the back plate, the light guide plate is mounted above the reflector, the optical film is mounted above the light guide plate, the plastic frame sleeves the back plate, the liquid display panel is mounted in the plastic frame and positioned above the optical film, and the outer frame sleeves the plastic frame. The lateral side of the back plate is provided with a light guide through hole corresponding to the light guide plate, the plastic frame is provided with a mounting groove at theposition of the lateral side of the back plate, and the light guide through hole is communicated with the mounting groove. A position, corresponding to the light guide through hole, of the reflectingmirror is obliquely mounted in the mounting groove, the heat radiating block is mounted in the mounting groove and positioned below the reflecting mirror, the LED light strip is mounted above the heatradiating block, and the lower portion of the heat radiating block is provided with a heat radiating groove. The practical liquid crystal display module is simple in structure and convenient to use,and integral heat radiating effects of the liquid crystal display module are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a practical liquid crystal display module. Background technique [0002] The liquid crystal display module has many advantages such as thin body and power saving, and is 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 backplane, and the LED light The heat of the strip is dissipated, and the outer frame and the plastic frame cooperate to fix the LCD panel. When the LED light strip is working, a lot of heat will be generated. The heat is concentrated on the inner side of the back panel and it is difficult to dissipate effectively. Continuous high temperature will not only affect the light strip. Normal operation will easily cause the light guide plate to expand due to heat, which will seriously affect the overall use effect and lifespan of the liquid crystal display mo...
