Abstract

The invention provides a touch display panel. The touch display panel comprises: a signal transmission wiring layer, wherein the signal transmission wiring layer comprises a plurality of signal transmission lines, the signal transmission lines are arranged in the first direction, and each signal transmission line extends in the second direction; and a touch electrode wiring layer, wherein the touch electrode wiring layer is arranged on one side of the signal transmission wiring layer, and the touch electrode wiring layer comprises a plurality of touch units which are arranged in an array mode, the orthographic projection of the part, corresponding to one touch control unit, of the signal transmission line on the touch control electrode wiring layer is partially overlapped with the corresponding touch control unit.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch display panel. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode, organic light emitting diode) due to light weight, self-illumination, wide viewing angle, low driving voltage, high luminous efficiency, low power consumption, fast response and other advantages, the application range is more and more extensive. In existing OLED touch display panels, touch circuits are directly deposited on the encapsulation layer instead of an external touch screen, thereby saving costs. [0003] However, the current encapsulation layer is thicker and has more particles, and since the signal transmission line of the self-capacitive touch circuit is at the lower end of the touch unit, it is very easy to cause a short circuit between the signal transmission line and the touch unit at the particle, resulting in abnormal touch.
