Abstract
A display device is provided that includes a plurality of sub-pixels. Each sub-pixel includes a light-emitting unit having an illumination area, wherein the illumination area is divided into a plurality of illumination regions, and each illumination region is configured to be illuminated independently. The light-emitting unit emits a light, and a gray level of the light is determined according to the total area of the illumination regions being illuminated.
Claims17
A display device comprising:
- a substrate;
- and
- a plurality of sub-pixels, wherein each of the plurality of sub-pixels comprises a light-emitting unit having an illumination area, wherein the illumination area is divided into a plurality of illumination regions, each of the plurality of illumination regions being configured to be illuminated independently;
- wherein the light-emitting unit emits a light, and a gray level of the light is expressed according to a total area of the plurality of illumination regions being illuminated
- wherein one of the plurality of light emitting units comprises:
- a first-type semiconductor layer disposed on the substrate;
- a light-emitting layer disposed on the first-type semiconductor layer;
- a second-type semiconductor layer disposed on the first-type semiconductor layer;
- a cathode electrode disposed on the first-type semiconductor layer;
- and
- an anode electrode disposed on the second-type semiconductor layer, wherein the anode electrode and the cathode electrode do not overlap with each other when viewed in a direction that is perpendicular to the substrate, and an area of the anode electrode is different from the cathode electrode.
