Problems solved by technology

The advantage of zonal dimming is that it can save power consumption and improve image quality. However, the existing backlight modules using light guide plates can only provide synchronous dimming in the whole area, so this kind of zonal dimming function cannot be realized.

Abstract

The invention discloses a spliced type light guide plate structure and a backlight module. The spliced type light guide plate structure comprises at least two light guide plate units, wherein each light guide plate unit comprises a first slope and a second slope and is matched with at least one illuminating unit; the first slope is arranged on one side of the light guide plate unit; the second slope is correspondingly arranged on the other side of the light guide plate unit; and the at least one illuminating unit is arranged under the first slope. According to the invention, the light guide plate is formed by splicing adjacent slopes, and the problem of limited length of the light guide plate is solved by changing the light propagation direction by the slope, so the spliced type light guide plate structure provided by the invention is fit for large-scale liquid crystal display and can realize light-dimming in areas.

Description

【Technical field】 [0001] The invention relates to a light guide plate structure and a backlight module, in particular to a spliced ​​light guide plate structure and a backlight module. 【Background technique】 [0002] Liquid crystal display (liquid crystal display, LCD) is a flat panel display device (flat panel display, FPD) that uses the characteristics of liquid crystal materials to display images. Power consumption and other advantages have become mainstream products in the entire consumer market. However, the liquid crystal material of the liquid crystal display cannot emit light by itself, and an external light source must be provided. Therefore, a backlight module is additionally provided in the liquid crystal display to provide the required light source. [0003] Generally speaking, backlight modules can be divided into side-type backlight modules and direct-type backlight modules. The side-type backlight module injects light from the side of the light guide plate, a...
