Backlight module and liquid crystal display

Abstract

The invention relates to a backlight module which comprises at least one light tube, a plurality of transparent buffer elements and a light guide plate, wherein each transparent buffer element is provided with a light tube inserting surface and a first reflecting surface which is opposite to the light tube inserting surface, and both tail ends of each light tube are respectively inserted into two transparent buffer elements by the light tube inserting surfaces; and the light guide plate is provided with an incidence surface, and the light tubes are configured beside the incidence surface.

Description

technical field [0001] The present invention relates to a liquid crystal display, and in particular to a liquid crystal display with good display quality. Background technique [0002] The liquid crystal display device can be roughly divided into two components: a liquid crystal display panel and a backlight module. The backlight module is used to provide sufficient brightness so that the liquid crystal display panel can display images. [0003] Figure 1A is a schematic diagram of a known backlight module, and Figure 1B for Figure 1A The schematic diagram of the light guide plate and the lamp tube of the backlight module. Please also refer to Figure 1A and Figure 1B In order to improve the luminance performance of the backlight module 100 , a light guide plate 110 with a V-groove (V-groove or V-cut) is usually used to concentrate the light so as to improve the utilization rate of the light source. [0004] It should be noted that the groove direction of the light gui...

Problems solved by technology

Therefore, corresponding to the end of the lamp tube 120, the backlight module 100 is likely to form a vignetting angle B.

The existence of the dark area A and the dark corner B will not only affect the display quality of the liquid crystal display device, but also affect the visual taste and comfort of the viewer when viewing
