Problems solved by technology

[0006] However, in the design of the known backlight module, there is no positioning member between the plastic frame and the lower cover for the X direction and the Y direction, and because of the necessity of the gap, the positioning effect between the components is indirectly caused. The components are easy to loosen, shake, or even be damaged and fall off. Therefore, the known backlight module will cause serious damage to the components due to the lack of positioning devices.

[0075] In addition, the first embodiment (vertical elastic positioning member), the second embodiment (transverse elastic positioning member) and the third embodiment (corner elastic positioning member) of the liquid crystal display of the present invention can exist in the lower cover of the same backlight module at the same time , to be used in conjunction with each other, and there is no limit to the number of its use. It can be selected and matched according to different conditions such as the size of the module, space utilization and configuration methods, so as to achieve the best positioning effect.

[0076] The liquid crystal display of the present invention can not only use elastic positioning members to solve the known positioning problems in the X direction and Y direction, but also retain the effect of the gap, and the positioning elastic member and the lower cover are integrally formed. Therefore, there is no need to spend extra processing, assembly procedures and ...

Abstract

The invention discloses a backlighting module, which includes a lower cover, a light guide plate, at least one optical mask and a light source. The lower cover includes a bottom part, a plurality of sides and a flexible position component, wherein, a plurality of sides are connected on the bottom so as to form a space in surrounding way, and the flexible position component is connected with a plurality of sides, and is extended towards the space. The light guide plate is arranged in the lower cover. The optical mask is arranged in front of the light guide plate. The light source is arranged in the lower cover in order to produce light beams, through the light guide plate and the optical mask, and then the light beams can be sent out from the backlighting module.

Description

technical field [0001] The invention relates to a backlight module. The backlight module has a positioning device to enhance the positioning effect between components. Background technique [0002] With the rapid advancement of science and technology, the quality of human life has also been improved. Traditional large-size, high-priced displays have been gradually replaced by today's lightweight, thin, low power consumption, high brightness, and low-cost liquid crystal displays. It is deeply loved and accepted by the public, allowing audio-visual users to enjoy a more perfect visual enjoyment. The backlight module is one of the main key components in the liquid crystal display. Since the liquid crystal itself does not emit light, the function of the backlight module is to supply sufficient brightness and uniform light distribution so that it can display images normally. [0003] see figure 1 The liquid crystal display 10 of the known technology includes a panel 101, a plas...
