Abstract

The embodiment of the invention provides an array substrate, a driving method thereof, a display panel and a display device, pertaining to the field of display technology. Therefore, the display device has a palmprint recognition function and a simple structure. The array substrate comprises multiple repeating units including multiple sub-pixels, each of which is provided with a display unit. One of the sub-pixels is provided with a palmprint recognition unit. The array substrate further comprises a touch electrode connected with touch electrode wires. Each display unit is connected with a first scanning line and data line, which is used for turning on or off each display unit under control of the first scanning line and inputting a data signal by the data line when the display unit is turned on. Each palmprint recognition unit is connected with a second scanning line, a control voltage terminal and a read signal line, which is used for acquiring a palmprint signal under control of the control voltage terminal and transmitting the acquired palmprint signal to the read signal line under control of the second scanning line. The array substrate is used for the display device with palmprint recognition function.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a driving method thereof, a display panel, and a display device. Background technique [0002] Liquid Crystal Display (LCD for short) has the advantages of low radiation, small size, and low energy consumption, and is widely used in electronic products such as tablet computers, televisions, and mobile phones. [0003] In addition, since the field of palmprint recognition technology was pioneered by the Hong Kong Polytechnic University and Tsinghua University in the late 1990s, it has been fully recognized by the academic community. It is of great significance for enhancing the security of electronic equipment and expanding its application range. [0004] However, most of the current liquid crystal displays do not have the palmprint recognition function, or achieve the purpose of palmprint recognition by adding an independent palmprint recognition c...
