The embodiment of the present invention discloses a touch display panel and a display device. The touch display panel includes: the display area includes a plurality of touch signal lines and a plurality of touch electrode blocks arranged in an array, and a touch electrode block It is electrically connected with a touch wire group, and the touch wire group includes at least one touch signal wire; the non-display area includes a plurality of touch source wires, at least one common voltage source wire and a multi-way selection circuit, and the multi-way selection circuit includes multiple A multi-way selection unit is set corresponding to a touch source line, the multi-way selection unit has m output terminals, one output end of the multi-way selection unit is electrically connected to a touch line group, and the multi-way selection unit The first input end of the unit is electrically connected to the touch source line, and the second input end of the multiplexing unit is electrically connected to the common voltage source line. In the embodiment of the present invention, the common voltage source line and the touch source line transmit signals through the touch line group and the touch electrode block in time-sharing, thereby realizing 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...
