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 liquid crystal display, electronic paper, OLED (OrganicLight-EmittingDiode, organic light-emitting diode) display and other display devices, as well as any products or components with display functions such as TVs, digital cameras, mobile phones, and tablet computers including 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 positioned ab...

Abstract

The invention provides an array substrate and a display apparatus, relates to the technical field of display, and is applied to manufacture of an array substrate and a display apparatus comprising the array substrate. The display apparatus integrates a fingerprint identification module on an array substrate so as to avoid individual manufacture of the fingerprint identification module and have the advantages of high integration and low cost. The array substrate comprises a fingerprint identification unit arranged at a non-display area of the array substrate. The fingerprint identification unit comprises an electrode layer, and a protective layer, multiple monitoring electrodes and a first insulation layer which are successively disposed on the electrode layer, wherein at least two monitoring electrodes are arranged in one fingerprint period, and all the monitoring electrodes are disposed at the same horizontal plane; and the electrode layer is used for forming an electric field with fingers, and the monitoring electrodes are used for outputting electric potential.

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...
