Abstract

The invention discloses a backlight module and a display device with the same. The backlight module comprises a frame, an optical film set, a light component and a reflecting sheet, a first light guide plate and a second light guide plate which are placed in the frame in sequence. The backlight module is characterized in that the first light guide plate contains at least two independent carriers with equal areas; light of the light component is emitted from the light inlet end by the first light guide plate to form a first backlight area; the light of the light component is emitted from the light inlet end by the second light guide plate and divided into a second backlight area and a third backlight area which are independent and equal in area. Through multi-screen and multi-area display of the backlight module, more comfortable man-machine interaction experience is brought to a user, and operation is simple and fast; meanwhile, compared with the prior art, through alternate execution of the two light guide plates of the backlight module at different times, rapid aging of the backlight module can be avoided, and the service life of the backlight module and the display device is prolonged.

Description

technical field [0001] The invention relates to a backlight module and a display device including the backlight module, which can effectively increase the capacity of screen information, bring more comfortable and pleasant operation experience to users, and are simple and quick to operate. Background technique [0002] With the popularization of mobile devices such as smart phones and tablet computers in daily life, small and medium-sized products, especially portable information products such as smart terminals, have made great progress. While constantly pursuing high-resolution, high-contrast, narrow-frame, and ultra-thin display devices, users pay more attention to the comfort, convenience, and humanization of mobile devices. Most of the existing mobile devices have a single display screen. In any application scenario, the only display screen needs to be turned on for operation. For more detailed and comprehensive information, for confidentiality or other reasons, custome...
