Abstract:
Device and method for an antireflective coating to improve image quality in an image display system. A preferred embodiment comprises a first high refractive index layer overlying a reflective surface of an integrated circuit, a first low refractive index layer overlying the first high refractive index layer, a second high refractive index layer overlying the first low refractive index layer, and a second low refractive index layer overlying the second high refractive index layer. The alternating layers of high refractive index material and low refractive index material form an optical trap, allowing light to readily pass through in one direction, but not so easily in a reverse direction. The dual alternating layer topology improves the antireflective properties of the antireflective layer and permits a wide range of adjustments for manipulating reflectivity and color point.
