Embodiment Construction

[0038] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0039] At present, the leakage current lead-out structure in the display panel in the prior art has relatively high resistance, and is generally designed as a mesh structure covering the entire display area. The voltage drop at different positions of the leakage current lead-out structure is different, which will cause leakage in the middle of the display area. The derived leakage current capability of the flow-leading structure is different from that of the leakage current-leading structure at the edge of the disp...

Abstract

The embodiment of the invention provides an organic light-emitting display panel and an organic light-emitting display device. The display panel comprises a substrate; a plurality of organic light-emitting units, wherein each organic light-emitting unit comprises a first electrode, a light-emitting function layer and a second electrode layer which are sequentially stacked in the direction away from the substrate; a plurality of block-shaped leakage current leading-out structures, wherein the block-shaped leakage current leading-out structures cover the plurality of organic light-emitting units, each block-shaped leakage current leading-out structure comprises a conductive layer with a plurality of light-transmitting areas, the conductive layers are in contact with the light-emitting function layer, and the light-transmitting areas are overlapped with the light-emitting areas of the organic light-emitting units; and a plurality of signal line, wherein one end of each signal line is connected with one block-shaped leakage current leading-out structure, the other end of each signal line is connected with a driving end, and the driving end provides driving voltage signals for the block-shaped leakage current leading-out structures. By the adoption of the scheme, electrical crosstalk between the adjacent light-emitting units is reduced, and the display effect is improved; and the brightness / chromaticity uniformity of the organic display panel is improved, the energy consumption is reduced, and the energy is saved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel and an organic light emitting display device. Background technique [0002] Existing organic light-emitting display devices, the pixel size can reach the micron level, and can be used to form micro-displays. Microdisplays have a broad market space, and are especially suitable for display devices of wearable devices. They provide an excellent solution for near-eye applications and are expected to set off a new wave of near-eye displays. [0003] With the reduction of the pixel size of the display device, the problem of electrical crosstalk between adjacent units will be caused. When a certain pixel unit has a display signal, part of the display current will be transmitted to the adjacent pixel unit, so that the pixel unit cannot display Predetermined pixel grayscale, which affects the display effect. In the prior art, a leakage cu...
