Abstract

The invention provides an OLED display panel and a display device. The OLED display panel comprises a substrate; a driving circuit layer; a planarization layer; a light-emitting function layer which comprises a pixel electrode layer, a pixel definition layer, light-emitting material layers and a common electrode layer, and packaging layers and a touch layer, wherein the pixel definition layer is patterned to form pixel definition areas and grooves, the grooves are formed between at least two adjacent pixel definition areas, the light-emitting material layers are formed in the pixel definitionareas, and the common electrode layer is flatly laid on the pixel definition layer and the light-emitting material layers; the thickness of packaging layers in groove areas is greater than the thickness of packaging layers outside the groove areas and outside the pixel definition area; the touch layer comprises a touch electrode, the touch electrode is of a grid structure surrounding the pixel definition area, and the projection of the touch electrode on the substrate at least partially coincides with the projections of the grooves on the substrate. Therefore, the distance between the common electrode and the touch electrode is increased, the parasitic capacitance between the common electrode and the touch electrode is reduced, and the touch reporting rate and the touch sensitivity of theOLED display panel are improved.

Description

technical field [0001] The present application relates to the display field, in particular to an OLED display panel and a display device. Background technique [0002] Capacitive touch screens are widely used in various electronic interactive scene devices due to their high durability, long life, and support for multi-touch functions. The working principle of the capacitive touch screen is to detect the specific position touched by the finger by detecting the change of capacitance at the position touched by the finger. [0003] Currently for flexible AMOLED (Active-matrix organic light-emitting diode, active-matrix organic light-emitting diode or active-matrix organic light-emitting diode) On-cell (integrated touch layer on the AMOLED cover) display screen, its touch The control electrodes are usually made directly on the upper surface of the thin film encapsulation layer. However, due to the thin film encapsulation layer (usually thickness <10um), the distance between t...
