Liquid crystal display with touch panel

Abstract

The invention has modified the conventional LCD structure, wherein a polarizing film is directly coated in the liquid crystal cell instead of the conventional polarizing plate, which is glued on the outer side of the liquid crystal cell. Then, the invention can prevent the direct contact between the polarizing film and the touch panel of film film (FF) type or in film plastic (FP) type. Thus, the touch panel on the LCD panel can adapt various technologies, so that the touch panel of FF type can be used without worrying about the damage on the polarizing film due to the pressure while a point touch is applied on the touch panel. Also and, for the touch panel of FP type, a conductive film can be directly coated on the panel substrate. The invention uses the coating polarizing film as an extraordinary mode (e-mode) polarizer. Also and, an ordinary mode (o-mode) polarizer can also be adapted, so as to expand the large viewing angle in good polarizing effect.
