Abstract

The invention provides an OLED (Organic Light Emitting Diode) display panel and an OLED display device. The OLED display panel comprises a drainage wire, the drainage wire is arranged in an area between adjacent light-emitting units, the drainage wire is arranged on the side, away from a light-emitting layer, of a hole layer, and the drainage wire is connected with the hole layer. According to the light-emitting device, the drainage wires are arranged, the drainage wires are arranged in the areas between the adjacent light-emitting units, so that the drainage wires lead out leakage currents between the adjacent light-emitting units through the hole layer and the drainage wires, the closed light-emitting units are prevented from being lightened, and the drainage wires are arranged on the side, away from the light-emitting layer, of the hole layer; and the drainage wires are prevented from being contacted with the electronic layer to influence display.

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] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display devices are widely used due to the advantages of self-illumination and flexible display. In an OLED display device, the red, blue and green sub-pixels emit light by exciting different light-emitting materials, but during the display process, for example, when the red sub-pixel is excited, a part of the current in the red sub-pixel will pass through the hole layer Transferred to other sub-pixels, such as the blue sub-pixel, causing the blue sub-pixel to also emit light, resulting in abnormal display. [0003] Therefore, there is a technical problem that the leakage current in the existing OLED display device causes the turned-off sub-pixels to be turned on, thereby causing abnormal display.
