Embodiment Construction

[0025] As mentioned in the background, in the existing display devices with fingerprint recognition function, the fingerprint recognition device is usually directly built into the housing of the display device, which increases the thickness and volume of the display device and increases the cost.

[0026] Therefore, the present invention provides a color filter substrate, an array substrate and a display device. The color filter substrate integrates the fingerprint sensing layer on the upper or lower surface of its non-display area, the array substrate integrates the fingerprint sensing layer on the upper or lower surface of its non-display area, and the The display device integrates the fingerprint sensing layer into one of its opposite first board body and second board body. Regardless of the color filter substrate, array substrate or display device provided by the present invention, the touch recognition function can be realized without increasing the thickness (or volume) ...

Abstract

Provided are a color film substrate, an array substrate and a display device. The color film substrate or the array substrate comprises a substrate body and a fingerprint sensing layer, wherein the substrate body is provided with a display area and a non-display area; and the fingerprint sensing layer is located in the non-display area and used for sensing and recognizing fingerprints. The color film substrate further comprises a color film layer, and the color film layer is arranged in the display area and used for filtering the color of light. The color film substrate or the array substrate integrates the fingerprint sensing layer, and accordingly the display device adopting the color film substrate or the array substrate has a fingerprint sensing and recognizing function; besides, due to the fact that the fingerprint sensing layer is integrated on the substrate body of the color film substrate or the array substrate, the thickness of the display device is not increased, and the cost of the display device is reduced.

Description

technical field [0001] The present invention relates to the display field, in particular to a color filter substrate, an array substrate and a display device. Background technique [0002] Fingerprints are inherent invariable features of the human body. Fingerprints are made up of a series of valleys and ridges on the skin surface of the fingertips. Each person's fingerprint is unique and can be distinguished from other people's fingerprints, so fingerprints can be used for personal identity verification. [0003] Existing common fingerprint identification devices are usually optical fingerprint sensing devices and semiconductor fingerprint sensing devices. Optical fingerprint sensing devices are usually bulky, and their applications are limited. The semiconductor fingerprint sensing device has the advantages of low price, small size and high recognition rate, and is more and more used in various electronic devices. Among them, the combination of the semiconductor finger...
