Problems solved by technology

If the pixels are formed with a small gap between them to ensure a good aperture ratio of the pixels, the spacer column area is reduced, the strength of the fine metal mask is reduced, and the reliability of the deposition may be reduced
On the contrary, if the pixel is formed with a large gap to improve the reliability of the deposition, the spacer column area increases, the strength of the fine metal mask increases, but the aperture ratio of the pixel may decrease
[0006] In addition, the formation of spacer columns may cause contamination, impurities, particles and other process problems due to the contact between the spacer columns and the fine metal mask, which will reduce the reliability of deposition, and ultimately affect the display effect and the performance of the display panel.

Embodiment Construction

[0033] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. The subsequent description of the specification is a preferred implementation mode for implementing the application, but the description is for the purpose of illustrating the general principle of the application, and is not intended...

Abstract

The invention discloses a display panel and a display device therefor. The display panel comprises an array substrate and a package substrate, wherein the array substrate comprises a substrate, a plurality of subpixels located on the substrate and arranged in an array, and spacer columns; the plurality of subpixels include a plurality of first pixels of a first color, a plurality of second pixelsof a second color and a plurality of third pixels of a third color, wherein each third pixel comprises at least two third subpixels; the edge of each third pixel is provided with recesses toward the inside of the pixel at the adjacent sides of two third subpixels; and at least one part of each spacer column is located in the corresponding recess.

Description

technical field [0001] The present application relates to the field of display technology, in particular, to a display panel and a display device thereof. Background technique [0002] An organic light emitting display device is a self-emitting display device including an organic light emitting diode (OLED) including a hole injection electrode, an electron injection electrode, and an organic emission layer formed therebetween. The organic light emitting display device emits light when excitons generated due to a combination of holes injected from the hole injection electrode and electrons injected from the electron injection electrode drop from an excited state to a ground state. [0003] Self-emissive display devices do not require additional light sources. Organic light emitting display devices can be driven at low voltage, and may be lightweight and formed of thin film technology. In addition, organic light emitting display devices have high-quality features such as wid...
