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

An embodiment of the present invention provides an organic light-emitting display panel and an organic light-emitting display device. The display panel includes a substrate; a plurality of organic light-emitting units, and each organic light-emitting unit includes a first electrode stacked in sequence along a direction away from the substrate; a light-emitting function layer and the second electrode layer; a plurality of block-shaped leakage current deriving structures, the block-shaped leakage current deriving structure covers a plurality of organic light-emitting units, the block-shaped leakage current deriving structure includes a conductive layer with multiple light-transmitting regions, the conductive layer and the light-emitting The functional layer is in contact, the light-transmitting area overlaps with the light-emitting area of ​​the organic light-emitting unit; a plurality of signal lines, one end of the signal line is connected to a block-shaped leakage current deriving structure, and the other end is connected to the driving end, and the driving end is a block The shape leakage current derivation structure provides the driving voltage signal. By adopting the solution, the electrical crosstalk between adjacent light emitting units is reduced, and the display effect is improved; at the same time, the luminance / chromaticity uniformity of the organic display panel is improved, and energy consumption is reduced to save energy.

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...
