Light-emitting diode display
This disclosure discloses a display including a first carrier, a second carrier, a light-emitting unit, a frame, and a protective layer. The first carrier includes a first electrode and a second electrode. The second carrier is arranged below the first carrier and includes a first connection pad and a second connection pad arranged on a side of the second carrier close to the first carrier. The light-emitting unit is arranged on the first carrier. The frame surrounds the light-emitting unit, and the protective layer covers the light-emitting unit. A distance between the first electrode and the second electrode is smaller than that between the first connection pad and the second connection pad.
1. A display unit, comprising:
a first carrier comprising a bottom contact layer;
a first electrical contact layer embedded in the first carrier, wherein the first electrical contact layer and the bottom contact layer are arranged on opposite sides of the first carrier;
a second carrier formed on the first carrier, and comprising a top surface, a bottom surface opposite the top surface, and a first connection pad arranged under the bottom surface in a configuration of connecting to the first electrical contact layer through a conductive material; and
a pixel unit arranged on the top surface of the second carrier and electrically connected to the first electrical contact layer for emitting different color lights, and comprising two or more light-emitting units, and a protective layer covering the light-emitting units.
2. The display unit of claim 1 , further comprising a frame surrounding the light-emitting units.
3. The display unit of claim 2 , wherein the frame comprises an opaque material.
4. The display unit of claim 2 , wherein the frame directly contacts the protective layer, and has a topmost surface higher than the light-emitting units.
5. The display unit of claim 1 , further comprising a second electrical contact layer embedded in the first carrier.
6. The display unit of claim 5 , the second carrier further comprises a second connection pad arranged under the bottom surface in a configuration of electrically connecting to the second electrical contact layer.
7. The display unit of claim 6 , wherein each of the light-emitting units comprises a first electrode and a second electrode connected to the second carrier.
8. The display unit of claim 7 , wherein the first connection pad and the second connection pad are separated from each other by a distance larger than a distance between the first electrode and the second electrode.
9. The display unit of claim 1 , wherein the different color lights comprises a red light, a green light, and a blue light.
10. The display unit of claim 1 , wherein the conductive material comprises solder, anisotropic conductive film (ACF) or anisotropic conductive paste (ACP).
