Abstract

The invention discloses an array substrate, a display panel and a display device. According to the invention, a fingerprint identification structure is arranged in the array substrate, and is not arranged at one side, far away from the display panel, of a backlight module in the prior art, so that in the embodiment of the invention, the backlight module does not need to be specially designed (suchas trepanning), the fingerprint identification device does not cause adverse effects on the uniformity of a backlight source provided by the backlight module, and the normal display of the display device can be ensured; and moreover, the embedded design of the fingerprint identification structure is realized, so that the thickness of the display device can be reduced, and the light and thin design is achieved while a fingerprint identification function is achieved. In addition, in the fingerprint identification process, the fingerprint identification device is closer to a fingerprint, and a signal received by the fingerprint identification device is stronger, so that the fingerprint identification device can perform identification quickly and accurately, and the efficiency and accuracy offingerprint identification are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an array substrate, a display panel and a display device. Background technique [0002] A liquid crystal display is a non-self-luminous device, which requires a backlight module, and uses the backlight provided by the backlight module to realize the display function. For liquid crystal displays, if the fingerprint recognition function is to be realized, a fingerprint recognition device needs to be installed, and in the current technology, the fingerprint recognition device is generally arranged on the side of the non-light-emitting surface of the backlight module, that is, the fingerprint recognition device is arranged on the backlight module. The side facing away from the display panel. [0003] However, in order to realize the fingerprint recognition function, openings need to be provided in the backlight module, so that the light reflected by the fingerprint can be incident ...
