Embodiment Construction

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] It should be noted that, in all the embodiments of the present invention, the definitions of "thin film", "layer" and "pattern" and the relationship between them need to be clarified. Among them, "thin film" refers to a layer of thin film made of a certain material on a substrate by deposition or other processes. If the "film" does not require a patterning process during the entire production process, the "film" can also be c...

Abstract

The invention provides an OLED display device, and relates to the technical field of display. The OLED display device solves the problem that an existing OLED sub-pixel is uneven in light-emitting brightness. The OLED display device comprises an array substrate and a package substrate which are packaged together, the array substrate comprises a first electrode layer, a second electrode layer and a light-emitting function layer located between the first electrode layer and the second electrode layer. The first electrode layer comprises a plurality of pixel electrodes which do not make contact with one another. The OLED display device is characterized in that the second electrode layer comprises a plurality of second electrodes which do not make contact with one another, and each second electrode corresponds to at least one pixel electrode. The display device further comprises transmission leads, and each transmission lead corresponds to one second electrode so as to input electric signals into the corresponding second electrode.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to an OLED display device. Background technique [0002] The light-emitting principle of an OLED (Organic Light) βmittingαiode, organic light-emitting diode) display panel is: depositing an organic material between two electrodes, and applying direct current to the organic material through the two electrodes to make it emit light. OLED display panels can be rolled and folded because of their self-luminous display and are made of organic materials, and have a very wide range of applications. [0003] like figure 1 As shown, the OLED display device includes an array substrate 10 and an encapsulation substrate 20 that are packaged together. On the first display substrate 11 of the array substrate 10, a driving thin film transistor 100, a first electrode (pixel electrode) 12, a light-emitting functional layer ( organic material) 13 , pixel walls 14 and second electrodes ...
