Abstract
An abrasion resistant coating (206) is applied to a display (202) of a mobile device (200). In an embodiment, the coating (140) includes a first layer (106B) including siloxane; a second layer (106A) including siloxane, wherein the second layer has opposing sides and a hardness greater than the first layer; and a third layer (104) including an amorphous carbon selected from a diamond-like carbon and a diamond-like nano-composite. The first layer (106B) and third layer (104) are positioned on opposing sides of the second layer (106A). The third layer (104) has a hardness greater than the second layer (106A).
