Problems solved by technology

However, since the transmission signal line and the reception signal line of the touch layer are connected to the signal terminals on the lower side of the display panel through both sides, and there is a display signal line between the transmission signal line and the reception signal line, resulting in a gap between the touch signal line and the display signal line. There is a parasitic capacitance between them, which will cause interference between the touch signal and the display signal, affecting the display effect and touch effect
[0003] Therefore, the existing Oncell display device has the technical problem of mutual interference between the touch signal and the display signal caused by the parasitic capacitance between the touch signal line and the display signal line.

Abstract

The invention provides an OLED display panel and an OLED display device. According to the OLED display panel, a touch binding terminal and a display binding terminal are arranged in two areas respectively, a touch binding terminal area is arranged outside the display binding terminal area, so that the touch binding terminal and the display binding terminal do not intersect; meanwhile, a touch signal line is connected with the touch binding terminal on one side corresponding to the touch binding terminal area, and the display signal lines are connected with the display binding terminals on the side corresponding to the display binding terminal area, so that the touch signal lines and the display signal lines do not intersect, stray capacitance between the touch signal lines and the display signal lines can be avoided, and interference between touch signals and display signals is avoided.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an OLED display panel and an OLED display device. Background technique [0002] With the development of display technology, in the existing mutual-capacitance Oncell (the touch layer is arranged between the light-emitting layer and the polarizer) OLED (Organic Light-Emitting Diode, organic light-emitting diode) display screen, the touch layer is arranged on the on the encapsulation layer to reduce the thickness of the display panel. Oncell display devices set the touch electrodes on the packaging layer, and the metal traces connecting the touch electrodes extend down to the signal terminals on both sides of the binding area through both sides, and then connect the touch chips with the signal terminals to realize touch control. function, and the driving circuit realizes the driving function by connecting with the driving chip, thereby realizing the touch control and dr...
