Abstract
A unit pixel and a displaying apparatus including the unit pixel are provided. The unit pixel includes a transparent substrate, a plurality of light emitting devices arranged on the transparent substrate, a light blocking layer disposed between the transparent substrate and the light emitting devices, and having at least one window, and a semi-transmissive layer disposed between at least one of the plurality of light emitting devices and the transparent substrate to overlap with the window at least partially.
Claims20
A unit pixel, comprising:
- a transparent substrate;
- a plurality of light emitting devices disposed on the transparent substrate;
- a light blocking structure disposed between the transparent substrate and the light emitting devices and having at least one window;
- and
- a semi-transmissive structure disposed between at least one of the plurality of light emitting devices and the transparent substrate, the semi-transmissive structure arranged to overlap with at least a part of one of the at least one window, wherein the semi-transmissive structure further comprises an island pattern located within the one of the at least one window, and wherein the semi-transmissive structure extends from the window and is arranged to cover at least a portion of an upper surface of the light blocking structure.
A unit pixel, comprising:
- a transparent substrate;
- a plurality of light emitting devices disposed on the transparent substrate, a light emitting device comprising a light emitting structure and an electrode pad;
- a light blocking structure disposed between the transparent substrate and the light emitting devices and having at least one window;
- a semi-transmissive structure disposed between at least one of the plurality of light emitting devices and the transparent substrate, the semi-transmissive structure arranged to overlap with at least a part of one of the at least one window, wherein the semi-transmissive structure further comprises an island pattern located within the one of the at least one window, and wherein the semi-transmissive structure extends from the at least one window and is arranged to cover at least a portion of an upper surface of the light blocking structure;
- and
- an insulation layer disposed between the light emitting structure and the electrode pad, wherein the insulation layer includes a first distributed Bragg reflector and the semi-transmissive structure includes a second distributed Bragg reflector.
A displaying apparatus, comprising:
- a circuit board having pads;
- a plurality of unit pixels disposed on the circuit board;
- and
- bonding materials for bonding the plurality of unit pixels to the pads, each of the unit pixels, comprising:
- a transparent substrate;
- a plurality of light emitting devices disposed on the transparent substrate;
- a light blocking layer disposed between the transparent substrate and the light emitting devices, and having at least one window;
- and
- a semi-transmissive structure disposed between the light blocking layer and the transparent substrate, the semi-transmissive structure at least partially overlapping with one of the at least one window, wherein the semi-transmissive structure further comprises an island pattern located within the one of the at least one window.
