Abstract

The embodiment of the invention discloses a touch display panel and a display device. The touch display panel comprises a plurality of multi-path selection units, wherein the input end of one multi-path selection unit and one touch source line are correspondingly arranged and electrically connected, the multi-path selection unit is provided with m output ends, and the m output ends of one multi-path selection unit are electrically connected with the touch line sets corresponding to the m adjacent touch electrode blocks in one column respectively. A non-display area further comprises m common voltage source lines and m common voltage switch control lines, and the ith common voltage switch control line controls transmission paths of multiple common voltage line sets corresponding to the ithcommon voltage source line and the (km + i)th row of touch electrode blocks to be conducted or cut off at the same time. In the touch stage, at least one touch line group transmits a touch signal, andat least one common voltage switch control line controls the common voltage source line corresponding to the touch line group to transmit a first voltage signal to the common voltage line group. Theembodiment of the invention realizes a narrow frame.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to a touch display panel and a display device. Background technique [0002] With the rapid development of display technology, touch display devices have gradually penetrated into everyone's life. Common touch display devices include smart phones, tablet computers and other touch display devices. [0003] The touch display device integrates a touch function and a display function. According to the structure of the integration mode of its touch function, touch display devices can be at least divided into plug-in type and built-in type. The embedded In cell touch display device integrates the touch electrodes inside the display panel. In order to achieve thinning, the common electrode layer is usually divided into multiple touch electrode blocks, and the display function is realized in the display stage and realized in the touch stage. touch function. [0004] At pr...
