Abstract

The embodiment of the invention provides a light guide plate and a preparation method thereof, a backlight module and a display device, and relates to the technical field of display. The component number of the backlight module can be reduced, and the poor deformation of the light guide plate is improved. The light guide plate comprises a light guide plate body and a reflecting layer, and the light guide plate body and the reflecting layer are integrally formed. The light guide plate body comprises a light emergent face, a bottom face and a plurality of side faces, wherein the bottom face is opposite to the light emergent face; the side faces are adjoined between the light emergent face and the bottom face; at least one of the side faces of the light guide plate body is a light incident face; the reflecting layer is arranged by clinging to the bottom face of the light guide plate body; the reflecting layer is made of a material with light reflection characteristics. The light guide plate is used for manufacturing the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a light guide plate and a preparation method thereof, a backlight source module and a display device. Background technique [0002] A Liquid Crystal Display (LCD for short) has become a mainstream product in flat panel displays due to its advantages of thinness, low cost, and electric drive. Since the liquid crystal itself does not emit light, it is necessary to install a backlight module in the LCD, and the thickness of the backlight module directly determines the thickness of the LCD. [0003] According to the position of the light source, the backlight module can be divided into direct type and edge type. [0004] Among them, the edge-lit backlight module can diffuse light to the entire display panel by setting a light source at the edge of the liquid crystal display panel and converting it into a surface light source by using a light guide plate. Compared with the direct-l...
