Patent ID: 7688409

Claim:
A parallax-free transflective liquid crystal display (LCD) device comprising, a top linear polarizer layer and a bottom linear polarizer layer, a first transparent substrate coated with transparent indium-tin-oxide (ITO) electrode and alignment film on an inner surface of the transparent substrate; a second transparent substrate; a first half-wave retardation film and a first quarter-wave retardation film sandwiched between the top linear polarizer and the first transparent substrate; a second half-wave retardation film and a second quarter-wave retardation film sandwiched between the bottom linear polarizer and the second transparent substrate; a liquid crystal layer positioned above a multilayer dielectric transflector layer sandwiched between the first transparent substrate coated with ITO and the second transparent substrate, wherein the multilayer dielectric transflector layer further comprises alternating layers of a high refractive index material and a low refractive index material positioned between the second transparent substrate and a layer of indium-tin-oxide; a voltage source; and a backlight source positioned below the bottom linear polarizer layer that passes light through the liquid crystal layer and further through the top linear polarizer while incident ambient light passes through the top linear polarizer into the liquid crystal layer and a portion of the incident ambient light is reflected backward from the liquid crystal through the top linear polarizer, such that during operation of the LCD there is no parallax.
