Abstract
A cover plate structure is provided. The cover plate structure includes a refractive layer that has a first refractive index and is divided into multiple refractive regions. There are multiple first protrusions on the first side of the refractive layer, and each refractive region corresponds to one first protrusion. The cover plate structure further includes at least one refraction structure disposed on the second side of the refractive layer and having a second refractive index. The second side is opposite the first side, and the second refractive index is different from the first refractive index.
Claims19
A cover plate structure, comprising:
- a refractive layer having a first refractive index and divided into refractive regions, wherein there are first protrusions on a first side of the refractive layer, and each of the refractive regions corresponds to one of the first protrusions;
- and
- at least one refraction structure disposed on a second side of the refractive layer and having a second refractive index, wherein the second side is opposite the first side, and the second refractive index is different from the first refractive index.
A display panel, comprising:
- a circuit substrate defining pixel regions;
- micro light-emitting chips disposed on the circuit substrate, wherein each of the pixel regions corresponds to at least one of the micro light-emitting chips;
- a refractive layer covering the pixel regions and having a first refractive index, wherein the refractive layer is divided into refractive regions that correspond to the pixel regions, and there are first protrusions on a first side of the refractive layer that is away from the circuit substrate, and each of the refractive regions corresponds to one of the first protrusions;
- and
- at least one refraction structure disposed on a second side of the refractive layer facing the circuit substrate and having a second refractive index, wherein the second refractive index is different from the first refractive index.
