Abstract: A method of forming a self-cleaning film system includes depositing a photocatalytic material onto a substrate to form a first layer. The method also includes disposing a photoresist onto the first layer and then exposing the photoresist to light so that the photoresist has a developed portion and an undeveloped portion. The method includes removing the undeveloped portion so that the developed portion protrudes from the first layer. After removing, the method includes depositing a perfluorocarbon siloxane polymer onto the first layer to surround and contact the developed portion. After depositing the perfluorocarbon siloxane polymer, the method includes removing the developed portion to thereby form the self-cleaning film system.

Abstract: A display comprises a substrate. Sets of light emitting diodes (LEDs) are arranged on the substrate. Each of the sets of LEDs comprises a red LED, a green LED, a blue LED, and each of the sets of LEDs forming a pixel of the display. A sensor is embedded in each of the sets of LEDs. The sensor is arranged in a plane in which the red, green, and blue LEDs are arranged in each of the sets of LEDs. A cover including a dielectric material covers the sets of LEDs. The sensor is configured to sense at least one of ambient light and proximity of an object to the cover.
