Patent ID: 7507438

Claim:
A method of establishing a diffuser surface coating on a substrate surface, said method comprising: providing a transparent substrate having a surface; providing an ultrasonic vibrating device; supplying a liquid coating material to said ultrasonic vibrating device; vibrating said ultrasonic vibrating device to atomize the coating material such that particles of the coating material are airborne; guiding said airborne particles via a low pressure air flow to guide said airborne particles onto the substrate surface to establish a coating of said coating material at said substrate surface, said low pressure air flow comprising an air flow of less than about 100 p.s.i; and curing said coating to form a durable diffuser coating at said substrate surface that provides reduced glare and that provides sufficient transparency and resolution when viewing through said coating and said transparent substrate when said diffuser coated substrate is used as a substrate for at least one of (a) a display device and (b) a touch screen device.
