Patent ID: 8400430

Claim:
A flat panel liquid crystal display device comprising: a front transparent rigid base; a rear transparent base; a liquid crystal fluid layer sandwiched between the front and rear bases; a rear polarizer layer on the rear transparent base; and a touch panel integrated into the display device over the front transparent rigid base, the touch panel comprising: a transparent flexible membrane including a front polarizer layer, a first transparent conductive layer on a lower surface of the front polarizer layer; and a second transparent conductive layer on an upper surface of the front transparent rigid base; wherein the first and second transparent conductive layers are double-index matched; a plurality of spacer bumps between the lower surface of the transparent flexible membrane and the upper surface of the rigid base, wherein the spacer bumps are sized and positioned such that they do not obstruct an active pixel area; and bus bars and a tail connected to the conductive layers.
