Embodiment 1

[0056] An embodiment of the present invention provides an array substrate, referring to figure 1 As shown, the array substrate includes: a fingerprint identification unit 1 disposed on the non-display area 20 of the array substrate; the fingerprint identification unit 1 includes: an electrode layer 3; a protective layer 4 and a plurality of monitoring electrodes 5 located on the electrode layer 3 in sequence And the first insulating layer 6, wherein at least two monitoring electrodes are arranged in one fingerprint period, and all monitoring electrodes are on the same level; wherein, the electrode layer 3 is used to form an electric field with the finger, and the monitoring electrode 5 is used to output potential.

[0057] It should be noted that there are valleys and ridges in the finger skin, and the continuous interlaced distribution of valleys and ridges constitutes a fingerprint. Refer to figure 2 As shown, for a finger, the protruding part of the fingerprint is the ridg...

Embodiment 2

[0078] An embodiment of the present invention provides a display device, including any one of the array substrates provided in Embodiment 1. The display device integrates the fingerprint identification module on the array substrate, avoiding the need to separately manufacture the fingerprint identification module, and has high integration and low cost. low feature. The display device can be a display device such as a liquid crystal display, an electronic paper, an OLED (Organic Light-Emitting Diode, organic light-emitting diode) display, and any product or component with a display function such as a TV, a digital camera, a mobile phone, a tablet computer, etc. that include these display devices .

[0079] Optionally, the above display device further includes: a detection circuit; the detection circuit is electrically connected to each monitoring electrode of the fingerprint recognition unit, and is used to measure the potential of each monitoring electrode when the finger is p...

Abstract

The invention provides an array substrate and a display device, which relate to the field of display technology. The display device integrates a fingerprint identification module on the array substrate, avoids separately manufacturing the fingerprint identification module, and has the characteristics of high integration and low cost. An array substrate includes: a fingerprint identification unit arranged in a non-display area of ​​the array substrate; the fingerprint identification unit includes: an electrode layer; a protective layer sequentially located on the electrode layer, a plurality of monitoring electrodes and a first An insulating layer, wherein at least two monitoring electrodes are provided in one fingerprint cycle, and all the monitoring electrodes are on the same level; wherein, the electrode layer is used to form an electric field with the finger, and the monitoring electrodes are used to output potential. The present invention is applicable to the fabrication of array substrates and display devices including the array substrates.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display device. Background technique [0002] In recent years, due to the increasing demand for confidentiality of personal information, biometric technology has emerged as the times require. Because there are different biological characteristics among different biological individuals, and the biological characteristics are difficult to be copied and stolen by others, such as fingerprints, voices or irises. Therefore, technologies that use biometric features to distinguish identities, such as fingerprint recognition technology, voiceprint recognition technology and iris recognition technology, have gradually become the mainstream of emerging protection technologies. [0003] Among them, fingerprint identification technology is widely used, especially mobile phones, notebooks, and tablets with fingerprint identification are sought after by consum...
