Problems solved by technology

And in order to meet the lightweight requirements of future products such as thinner thickness and smaller volume, the light source generator 16 in the backlight module 10 is often installed in a narrow and small airtight space, so the heat energy generated during operation is often unable to It is emitted smoothly and accumulates continuously. Once the operation time is a little longer, it will easily cause the temperature near the lamp tube to be too high.

Abstract

The present invention relates to a sidelight type backlight module, including a light-conducting plate, at least a light source generator placed at side of said light-conducting plate and used for providing a light source and making said light source be entered into said light-conducting plate, at least a reflector placed around said light source generator relatively to the outside of said light-conducting plate and used for reflecting the light produced by said light source generator onto said light-conducting plate, a frame placed in the lower portion of said light-conducting plate and said reflector and used for covering outside of said reflector and a heat-dissipative pad placed between said reflector and said frame.

Description

technical field [0001] The invention relates to an edge light backlight module, in particular to an edge light backlight module with a high cooling effect. Background technique [0002] The backlight module is one of the key components of the liquid crystal display, and has been widely used in digital cameras, digital personal assistants (PDAs), computer monitors and flat-screen TVs. Generally speaking, the backlight module is arranged under a display panel, and has a light source and a light guide plate, which are used to provide a uniformly dispersed light to the display panel, and then control the pixel electrodes on the display panel to form appropriate of the image. Wherein, the backlight module can be divided into a direct type backlight module whose light source is directly below the display panel or an edge light type backlight module whose light source is near the side of the display panel according to the location of the light source. In addition, since the edge-...
