A backlight module, its control method, and a wearable device

Abstract

The invention discloses a backlight module, a control method, and a wearable device, and relates to the field of display technology, in order to improve the partition dimming performance of the backlight module, so that the image displayed by the display device has a better contrast between light and dark. The backlight module includes a light source and a light guide plate, the light guide plate includes a transparent substrate and a plurality of dimming units with reflection function, the light source is arranged on the side of the transparent substrate, and the plurality of dimming units are arranged on the transparent substrate On one surface, the dimming unit is used to adjust the output intensity of the light emitted by the light source on the surface of the transparent substrate away from the dimming unit. The method for controlling the backlight module is used for controlling the above-mentioned backlight module. The backlight module, the control method and the wearable device provided by the present invention are used to improve the contrast between light and dark of the picture.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a backlight module, a control method, and a wearable device. Background technique [0002] Virtual reality (Virtual Reality, abbreviated as VR) technology is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. System simulation of physical behavior immerses the user in the environment. [0003] In the prior art, VR glasses are a wearable display device that applies virtual reality technology to a display device, which makes the user experience an immersive feeling. When the display device in the VR glasses is a liquid crystal display device, due to the small size of the VR glasses, the partition dimming performance of the backlight module is relatively poor, resulting in poor light and dark contrast of the image displayed by the VR glasses, and it is impossible to distinguish the difference in imag...
