Touch screen used in e.g. input device of motor car, has two polarization filters that are acted as upper and lower polarizers of screen plate, in which one filter is rotated with respect to reflective inner surface at Brewster angle

摘要

The touch screen (1) has a touch-sensitive plate (3) that is arranged on a screen plate (4) formed with imaging layers. The touch-sensitive plate is covered by a first polarization filter (5), and is provided with a touch-sensitive coating structure. The back (25) of the screen plate is covered by second polarization filter (6). The first polarization filter is acted as upper polarizer of screen plate. The second polarization filter is acted as lower polarizer of screen plate. The first polarization filter is rotated with respect to reflective inner surface (7) at Brewster angle.
