Abstract
The present invention provides a display panel and a manufacturing method of the display panel. In the present invention, an adjustment structure is arranged on the light-emitting layer, and black photosensitive particles are arranged in the adjustment structure. When the display panel is in a bright state, light emitted by the light-emitting unit illuminates the black photosensitive particles, and the black photosensitive particles move toward positions corresponding to first gaps. Therefore, brightness at the light-emitting units is increased, and brightness at the first gaps is decreased. Accordingly, a contrast ratio of the display panel is increased.
Claims20
A display panel, comprising:
- a substrate;
- a light-emitting layer disposed on the substrate, wherein the light-emitting layer comprises a plurality of light-emitting units, and a first gap is defined between each two of the light-emitting units;
- and
- an adjustment structure arranged on one side of the light-emitting layer away from the substrate, wherein the adjustment structure comprises a plurality of black photosensitive particles in the adjustment structure;
- wherein when the display panel is in a bright state, light emitted from the light-emitting units illuminate the black photosensitive particles, and the black photosensitive particles move to positions corresponding to the first gaps.
A manufacturing method of a display panel, comprising the following steps:
- producing a light-emitting layer on a substrate, wherein the light-emitting layer comprises a plurality of light-emitting units, and a first gap is defined between each two of the light-emitting units;
- and
- producing an adjustment structure on one side of the light-emitting layer away from the substrate, wherein the adjustment structure comprises a plurality of black photosensitive particles, wherein when the display panel is in a bright state, light emitted from the light-emitting units illuminate the black photosensitive particles, and the black photosensitive particles move to positions corresponding to the first gaps.
