Abstract

The invention provides a display device. The display device comprises a display panel, a first backlight module, a second backlight module, a light sensor and a visual angle regulation and control assembly. The first backlight module comprises an optical element, at least part of the area of the optical element is completely opposite to the display sensing area, and the optical element can realize switching between a fog state and a transparent state; the visual angle regulation and control assembly is arranged between the display panel and the light sensor and corresponds to the display sensing area; when the optical element is in the fog state, the visual angle regulation and control assembly is used for shrinking the emergent angle of backlight penetrating through the visual angle regulation and control assembly; and when the optical element is in the transparent state, external light rays penetrate through the visual angle regulation and control assembly and the first backlight module to enter the light sensor, the function of the light sensor is executed, on the premise that the function of the light sensor is not affected, the uniformity of the backlight visual angle of the first backlight module is improved, and the display effect is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Currently, liquid crystal displays (Liquid Crystal Displays, LCDs) are widely used in electronic devices such as high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, and digital cameras. Especially in the field of small and medium liquid crystal displays, under-screen sensor technology and transparent display technology have become a must for the industry. [0003] In the under-screen sensor technology, a special design for the backlight module is required. For example, a common backlight module is used with a transparent backlight module, so that the signal light can reach the under-screen sensor area through the transparent backlight module to realize the corresponding recognition function. However, when the transparent backlight module is only used to provide ba...
