ABSTRACT:
In a LC matrix display with an internal reflector and an internal measuring reticle metal electrodes made of chromium, nickel, aluminum or some other metal are used as the internal reflector. By a special configuration of electrodes it is achieved that the measuring reticle is formed in the LC layer itself as a consequence of the optical effects in the liquid crystal. By building in an internal reflector and an internal measuring reticle any parallax is removed when observing the signal curve as well as the measuring reticle and, additionally, a maximum viewing angle is assured.
