Abstract

The embodiment of the invention provides a light guide plate, a die thereof, a making method, a backlight module and a display device. The light guide plate conducts emergent light of a light source. The light guide plate comprises an incident light surface, and the incident light surface is fit with the emergent light surface of the light source. The light guide plate can be formed with the light source as a whole. The light guide plate die is used for making the above light guide plate. The light guide plate die comprises a bottom plate and a side plate, and the side plate at the incident light side is a circuit board comprising the light source. According to the light guide plate, the die thereof and the making method of the embodiment of the invention, the incident light surface of the light guide plate is fit with the emergent light surface of the light source, the gap between the light guide plate and the light source can be reduced and eliminated, light loss can be reduced, energy consumption is reduced, and the display effects are improved.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display technology, in particular to a light guide plate and its mold and manufacturing method, a backlight module and a display device. Background technique [0002] Conventional liquid crystal displays require a backlight module behind the liquid crystal display panel. The backlight module generally includes a light source, a light guide plate, and optical film materials. Due to the gap between the light guide plate and the light source, all the light emitted from the light source cannot be transmitted by the light guide plate to illuminate the liquid crystal display panel, which will cause light loss, increase energy consumption, and reduce display quality. Summary of the invention [0003] The embodiment of the present invention provides a light guide plate, a mold and a manufacturing method thereof, a backlight module, and a display device. [0004] According to the first aspect of the present...
