Abstract

The invention discloses an LCD backlight module convenient to demount. The LCD backlight module comprises a fixing base and a reflector. A light guide plate is arranged on the reflector. A light-emitting module is mounted on the left of the light guide plate. An inverse-edge light-condensation piece is arranged on the light guide plate. An inverse-edge mirror surface is mounted on the lower portion of the inverse-edge light-condensation piece. A forward-edge light-condensation piece is arranged on the inverse-edge light-condensation piece. A prism surface is laid on the upper surface of the forward-edge light-condensation piece. An upper diffuser is arranged on the forward-edge light-condensation piece. Through holes are formed in the right edge of the fixing base. A fixing clamp is arranged on the left of each through hole. The fixing base comprises radiating windows. The LCD backlight module has the advantages that the structure of the LCD backlight module is reasonable and perfect by adding new functions and overcoming original defects, an optimized effect can be achieved, the LCD backlight module can be demounted and mounted conveniently, and work efficiency of people is increased greatly.

Description

technical field [0001] The invention belongs to the technical field of backlight modules, and in particular relates to a conveniently disassembled LCD backlight module. Background technique [0002] The LCD backlight module is one of the key components of the LCD panel. The function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. The so-called backlight is a light source located behind the liquid crystal display (LCD " "), and its luminous effect will directly affect the visual effect of the liquid crystal display module (LCM). Liquid crystal itself does not emit light, it displays graphics or characters as a result of its modulation of light. The development of backlight can be traced back to World War II. At that time, ultra-small tungsten filament lamps were used as backlights for aircraft instruments. This is the initial stage of backlight development. After half a century of development, backlight has b...
