Abstract
The invention discloses a touch display substrate, a display panel and a display device. It belongs to the field of display technology and includes: a display area; the display area includes a plurality of pixels; the display area includes repeating units arranged repeatedly along a first direction; the repeating unit includes a first pixel column, a second pixel column, and a first The data line and the second data line; the display area includes a plurality of fingerprint identification electrodes, a plurality of fingerprint electrode lines and a plurality of control switches; wherein, the fingerprint identification electrode and the pixel electrode or the common electrode are arranged on the same layer, perpendicular to the touch display substrate In the direction of the fingerprint recognition electrode and the pixel electrode do not overlap; the fingerprint electrode line and the control switch are located in the area between two adjacent repeating units; the gate of the control switch is electrically connected to the gate line, and the source of the control switch The pole is electrically connected to the fingerprint electrode line, and the drain of the control switch is electrically connected to the fingerprint identification electrode. Compared with the prior art, it is beneficial to realize a full screen.
Description
technical field [0001] The present invention relates to the field of display technology, and more specifically, to a touch display substrate, a display panel and a display device. Background technique [0002] In a display device provided in the prior art, a fingerprint recognition function is integrated. When using the display device, the user can use the fingerprint identification function to make the display device perform a specific function. The fingerprint recognition function is convenient, fast, and highly secure, and is one of the research and development directions of the display device. [0003] However, in the display device provided by the prior art, an additional fingerprint recognition module needs to be added to realize the fingerprint recognition function. For example, please refer to figure 1 , figure 1 It is a structural schematic diagram of a display device provided by the prior art. figure 1 The shown display device includes a display panel 01 and a...
