Abstract

The invention provides a backlight module and a display device. The backlight module is provided with an in-plane opening and further comprises a light source device and a light guide body; the lightsource device comprises a first light source and a second light source which are independently driven and controlled; the light guide body is arranged on the hole wall of the in-plane opening, is opposite to the first light source, and is used for providing light emitted by the first light source to the area of the in-plane opening under a preset condition. Compared with the prior art, the backlight module has the advantages that the in-plane opening only serves as a receiving and transmitting channel of ambient light of a camera device below the in-plane opening, no light source provides brightness, the problem that the in-plane opening in the backlight module of a liquid crystal display device in the prior art has no light source to provide brightness is solved, and therefore the in-plane opening of the backlight module with brightness under preset conditions is achieved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a backlight module and a display device. Background technique [0002] With the advent of the information age, displays have become the standard interface for man-machine communication. More than 80% of human beings obtain information from the outside world comes from vision. Therefore, display devices with rich colors, moderate brightness, energy saving and environmental protection play a very important role in human production, life and various human-computer interaction occasions. In recent years, with liquid crystal (Liquid Crystal Display, abbreviated as LCD), light display (Digital Light Processing, abbreviated as DLP) rear projection, plasma and other display technologies are gradually improved. [0003] Liquid crystal is a substance between solid and liquid. It is an organic compound with regular molecular arrangement. If it is heated, it will appear in a ...
