A wavelength conversion unit arrangement, comprising:
- a carrier;
- and
- a wavelength conversion unit, comprising a first wavelength conversion layer and a filter layer, the wavelength conversion unit being attached to the carrier by the filter layer, the filter layer having a first surface facing the carrier and a second surface facing away from the carrier;
- wherein the first surface and the second surface have different textures.
A method of manufacturing a pixel module, comprising:
- providing a light-emitting element, the light-emitting element having a light-exiting surface;
- providing a wavelength conversion unit arrangement, the wavelength conversion unit arrangement comprising a carrier and a wavelength conversion unit arranged on the carrier, the wavelength conversion unit comprising a first wavelength conversion layer and a filter layer, and the filter layer having a first surface facing the carrier and a second surface facing away from the carrier;
- and
- transferring the wavelength conversion unit to the light-exiting surface and exposing the first surface;
- wherein the first surface after the transferring step and the second surface before the transferring step have different textures.
A light-emitting component, comprising:
- a chip, having a light-exiting surface;
- and
- a light reflecting layer, surrounding the chip and exposing the light-exiting surface;
- wherein the light reflecting layer has an upper surface, and the upper surface has a texture extending from the light-exiting surface.
