Micro light-emitting diode displays having color correction films applied thereto
Micro light-emitting diode displays having color correction films applied thereto and methods of applying color correction films to a display are described. In an example, a method of fabricating a micro light emitting diode display includes applying a color correction film to a flexible transparent backing film. The method also includes placing the flexible transparent backing film over a display with the color correction film facing the display. The method also includes applying a laser to a portion of the flexible transparent backing film to eject a patch of the color correction film onto the display.
1. A method of fabricating a micro light emitting diode display, the method comprising:
applying a color correction film to a flexible transparent backing film;
placing the flexible transparent backing film over a display with the color correction film facing the display, the display having a microgroove; and
applying a laser to a portion of the flexible transparent backing film to eject a patch of the color correction film into the microgroove of the display, the microgroove larger than the patch of the color correction film.
2. The method of claim 1 , wherein the flexible transparent backing film comprises a release layer, and applying the color correction film to the flexible transparent backing film comprises applying the color correction film to the release layer.
3. The method of claim 2 , wherein applying the laser to the portion of the flexible transparent backing film comprises laser ablating a portion of the release layer to eject the patch of the color correction film onto the display.
4. The method of claim 1 , wherein the color correction film comprises quantum dots.
5. The method of claim 1 , wherein the flexible transparent backing film is a continuous roll.
6. The method of claim 1 , wherein the color correction film is pre-shaped into a plurality of patches prior to applying the laser.
7. The method of claim 1 , wherein the color correction film is a continuous film.
8. The method of claim 1 , wherein the display comprises a pixel structure comprising a green micro light emitting diode device, a first blue micro light emitting diode device, and a second blue micro light emitting diode device.
9. The method of claim 8 , wherein the patch of the color correction film is ejected onto a portion of the display over the second blue micro light emitting diode device.
10. The method of claim 9 , wherein the patch of the color correction film converts blue light from the second blue micro light emitting diode device to red light.
11. A method of fabricating a micro light emitting diode display, the method comprising:
applying a color correction film to a flexible transparent backing film;
placing the flexible transparent backing film over a display with the color correction film facing the display, the display having a microgroove; and
locally heating a portion of the flexible transparent backing film to melt a patch of the color correction film into the microgroove of the display, the microgroove larger than the patch of the color correction film.
12. The method of claim 11 , wherein locally heating the portion of the flexible transparent backing film comprises heating with a laser.
13. The method of claim 11 , wherein the flexible transparent backing film comprises a release layer, and applying the color correction film to the flexible transparent backing film comprises applying the color correction film to the release layer.
14. The method of claim 11 , wherein the color correction film comprises quantum dots.
15. The method of claim 11 , wherein the flexible transparent backing film is a continuous roll.
16. The method of claim 11 , wherein the color correction film is pre-shaped into a plurality of patches prior to locally heating.
17. The method of claim 11 , wherein the color correction film is a continuous film.
18. The method of claim 11 , wherein the display comprises a pixel structure comprising a green micro light emitting diode device, a first blue micro light emitting diode device, and a second blue micro light emitting diode device.
19. The method of claim 18 , wherein the patch of the color correction film is ejected onto a portion of the display over the second blue micro light emitting diode device.
20. The method of claim 19 , wherein the patch of the color correction film converts blue light from the second blue micro light emitting diode device to red light.
