Abstract

The embodiment of the invention provides an array base plate, a driving method of the same, a display panel and a display device and relates to the technical field of displaying. The display device possesses a palmprint recognition function and simple structure. The array base plate comprises a plurality of repeat units. Each repeat unit is formed by a plurality of sub-pixels; each sub-pixel is provided with a displaying unit; one of the sub-pixel is provided with a palmprint recognition unit; the array base plate further comprises a touch control electrode connected with a touch control electrode line; the display unit is formed by a first scanning line and a data line to open or close the display unit controlled by the first scanning line; a data signal can be input by the data line when the displaying unit is opened; the palmprint recognition nit is connected with the first scanning line, a second scanning line, a voltage controlling end and a signal-reading line to collect the palmprint signal under the control of the second scanning line and the voltage controlling end, and to send the collected palmprint signal to the signal-reading line under the control of the first scanning line; and at the signal is sent to the displaying device having the 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 the purpose of palmprint recognition has been achieved by adding an independent palmprint rec...
