Abstract

The invention discloses a touch display panel and a display apparatus. Lead terminals corresponding to pins of a touch driving chip in the touch display panel are arranged in a matrix, and at least one second terminal corresponding to a touch signal line is arranged in each row or column of the lead terminals, so that first terminals corresponding to data lines and the second terminals corresponding to the touch signal lines are arranged in a mixed way, and leads corresponding to the data signal lines and leads corresponding to the touch signal lines are arranged on a same layer. Compared with the prior art, a layer of metal and a corresponding fabrication process do not need to be additionally added for fabricating the leads corresponding to the touch signal lines separately, so that the fabrication cost can be reduced; and meanwhile, the problems of various bad phenomena and relatively large occupied space of wiring caused by additional metal routing can be solved, so that the product yield is increased.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch display panel and a display device. Background technique [0002] With the thinning and lightening of the touch panel, the research on the integration of the touch panel and the liquid crystal display substrate is becoming more and more popular. Among them, the in-cell touch solution, which embeds the function of the touch panel into the liquid crystal display substrate, has attracted widespread attention. At present, the implementation scheme of the self-contained embedded touch panel is: divide the transparent electrode layer used as the common electrode on the display substrate into several electrode squares as the touch electrodes, and connect one end of the touch signal line to the touch electrodes , and the other end is connected to the touch driver chip, so as to realize the transmission of the touch signal, and then determine the position where the touch...
