Abstract

The invention discloses a display panel, a preparation method thereof and a silicon-based organic light-emitting micro-display. The display panel comprises an underlayment substrate which is provided with at least one pixel area and a non-pixel area surrounding the pixel area on the surface thereof; a pixel limiting layer which is located on the underlayment substrate, covers the non-pixel area and exposes the opening of the pixel area; and an organic light-emitting layer and an isolation structure which are located on the underlayment substrate. The organic light-emitting layer is located in the pixel area, the isolation structure is located on the surface, away from the underlayment substrate, of the pixel limiting layer and located in the non-pixel area, and the surface, away from the underlayment substrate, of the isolation structure is a plane. According to the invention, the effect of accurately disconnecting the continuous non-pixel area part in the organic light-emitting layer is achieved.

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...
