Patent ID: 8647727

Claim:
An optical assembly comprising: a liquid crystal display assembly; a backlight source comprising light emitting diodes; a first translucent substrate; a second translucent substrate; a first layer of adhesive bonded to the first translucent substrate, the first layer of adhesive being configured for diffusive effects; and a second layer of adhesive bonded to the second translucent substrate, the second layer of adhesive being configured for diffusive effects, wherein the second layer of adhesive includes particles, the particles being patterned in association with placements of the light emitting diodes of a backlight, the particles being provided so that diffusion is greater in the second layer of adhesive at areas that are closer to a light emitting diode of the light emitting diodes; and a third layer of adhesive being configured to bond the LCD adhesive assembly to the next optical layer or optical component of the optical assembly; wherein the first layer of adhesive, the second layer of adhesive, and the third layer of adhesive each have different diffusion characteristics, and the first layer of adhesive has a transmissiveness level that is less than a transmissiveness level of the second layer of adhesive.
