Abstract

The invention discloses a display panel, a preparation method thereof, and a silicon-based organic light-emitting microdisplay. The display panel includes a base substrate, the surface of the base substrate is provided with at least one pixel area and a non-pixel area surrounding the pixel area; a pixel definition layer, the pixel definition layer is located on the base substrate, covers the non-pixel area, and exposes the pixel area The opening of the organic light-emitting layer and the isolation structure, the organic light-emitting layer and the isolation structure are located on the base substrate, wherein the organic light-emitting layer is located in the pixel area, and the isolation structure is located on the surface of the pixel definition layer away from the base substrate, and is located on the non-pixel area, the surface of the isolation structure away from the base substrate is a plane. The present invention achieves the effect of accurately disconnecting the continuity of the non-pixel region in the light-emitting machine layer.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a silicon-based organic light-emitting microdisplay. Background technique [0002] Existing organic light-emitting display panels, such as silicon-based organic light-emitting display panels, have a very small pixel pitch, because organic materials themselves are semiconductors and have certain charge transfer capabilities, especially hole injection materials. It is very small, and silicon-based micro-displays are vapor-deposited on a common mask, and the material has good continuity. Therefore, when one of the pixels is lit, part of the current is more likely to leak to adjacent pixels, and the It causes adjacent pixels to emit light slightly, which is the so-called crosstalk. Pixel crosstalk will cause the color coordinates to shift after lighting, and the color purity is poor. In severe cases, it c...
