Abstract

The invention discloses an edge-lit type light-emitting diode (LED) backlight module and a television and achieves a technical effect that a liquid crystal display panel is more uniform in display luminance. The edge-lit type LED backlight module comprises a back plate, a light guiding plate, N sets of LED light sources and a liquid crystal display panel. The light guiding plate is arranged on the surface of the back plate and N corner portions of four corner portions of the light guiding plate are wedge-shaped. An i set of LED light sources and an i corner portion of the N corner portions are correspondingly arranged, and i is an arbitrary integer from 2 to N. Incident lights which are produced by the i set of LED light sources enter into the light guiding plate from the i corner. The liquid crystal display panel is arranged on the surface of the light guiding plate. The i set of LED light sources of the N sets of LED light sources comprises a first set of LED light sources and a second set of LED light sources which is connected with the first set of the LED light sources. A first incline angle is located between the first set of LED light sources and a first lateral edge of the light guiding plate. A second incline angle is located between the second set of LED light sources and the first lateral edge of the light guiding plate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a side-light LED backlight module and a TV set. Background technique [0002] With the development of electronic technology, more and more electronic devices have been produced, among which, many electronic devices have liquid crystal display screens. Usually, liquid crystal display screens include liquid crystal panels and backlight modules. The liquid crystal panels are composed of two layers A liquid crystal layer is sandwiched between the glass backplane. Since the liquid crystal panel itself does not emit light, it needs to provide a uniform light source system through the backlight module. [0003] In the prior art, the LCD panel can be provided with a light source system through a direct-type backlight module or an edge-type backlight module. In this case, please refer to figure 1 , the side-type backlight module includes the following structure: [0004] Backplane 101;...
