Array substrate, color-film substrate and touch display device

Abstract

The invention provides an array substrate. The array substrate comprises a display region, a non-display region and a first fingerprint identifying unit, wherein the non-display region is provided with a plurality of gate lines, a plurality of data lines and a driving chip; the display region is provided with a common electrode layer; the gate lines and the data lines are intersected to one another in an insulated manner so as to define a plurality of pixel units which are distributed in an arrayed manner; each pixel unit comprises a pixel thin-film transistor and a pixel electrode; the common electrode layer comprises a plurality of first touch units which are insulated from one another; each first touch unit corresponds to a plurality of pixel units; and the first fingerprint identifying unit is used for identifying fingerprints. The array substrate comprises the fingerprint identifying unit. Compared with a simple fingerprint identifying device arranged in electronic equipment in the prior art, the array substrate with the fingerprint identifying device is high in screen occupation rate and is thin. The invention also provides a color-film substrate for identifying fingerprints and a touch display device of the color-film substrate.

Description

technical field [0001] The present invention relates to the display field, and more specifically, to an array substrate, a color filter substrate and a touch display device. Background technique [0002] With the continuous development of electronic equipment, fingerprint identification has become a major selling point of electronic equipment. Currently, 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. [0003] The combination of the semiconductor fingerprint sensing device and the display device can undoubtedly bring a series of advanced functions, for example, the fingerprint recognition device can be used to safely perform o...
