Abstract

An embodiment of the invention provides an array substrate, a touch control panel, a touch display device and a driving method of the array substrate and relates to the field of display and used for reducing border width of the display device. The array substrate comprises at least one driving circuit, one fingerprint unit arranged in a display area and multiple display units, the display units are arranged in array, and each row of the display units corresponds to one display grid line; the fingerprint unit comprises multiple fingerprint electrodes arranged in array and X fingerprint grid lines, and each row of the fingerprint electrodes corresponds to one fingerprint grid line; each driving circuit comprises N-level mutual cascaded driving units, any one level driving unit is connected with at least one display grid line, the X-level driving units are reused as X-level shared driving units, the j-level shared driving unit is connected with the j-level fingerprint grid line, and driving electric signals are provided through the fingerprint units; 1 is smaller than and equal to X smaller than and equal to N, 1 is smaller than and equal to j smaller than and equal to X, and j, X and N are positive integers.

Description

technical field [0001] The present invention relates to the display field, in particular to an array substrate, a touch panel, a touch display device and a driving method thereof. Background technique [0002] The uniqueness and invariance of the human body fingerprint make the security performance of the fingerprint identification stronger, and because of its simple operation, it is widely used in various fields, for example, the field of display technology. [0003] In the field of display technology, taking a mobile phone as an example, when unlocking or opening a specific application, it can be done through fingerprint recognition. [0004] However, fingerprint identification needs to add a corresponding driving circuit. In the prior art, the driving circuit is arranged in a non-display area of ​​the display device, thereby increasing the frame width of the display device. Contents of the invention [0005] Embodiments of the present invention provide an array substra...
