DISPLAY DEVICE WITH INTEGRAL TOUCH PANEL SURFACE

摘要

A touch panel (110) is integrated into a flat panel display device (180) having a visual display surface with a front polarizer layer (160), particularly a liquid crystal display device (180). The touch panel (110) comprises a flexible transparent membrane containing the front polarizer layer (160) and having a first transparent conductive layer (134) on a lower surface of the flexible transparent membrane and a rigid base (120) comprising the flat panel display device (180) and having a second transparent conductive layer (124) on an upper surface of the rigid base (120). At least one spacer (40B) separates the flexible transparent membrane from the rigid base, keeping the first and second transparent conductive layers in spaced-apart facing relationship. A bus bar (44) and tail (46, 48) communicate a signal from the touch panel to the flat panel display device (180).
