Abstract:
PCT No. PCT/EP93/00864 Sec. 371 Date Dec. 12, 1994 Sec. 102(e) Date Dec. 12, 1994 PCT Filed Apr. 7, 1993 PCT Pub. No. W093/20554 PCT Pub. Date Oct. 14, 1993.A selectively alterable optical data memory (10) has a liquid crystal display (12) with a nematic medium (22), which consists of a nematic phase and a solid dispersed in it, a first voltage source (26), a second voltage source (30) and a modulable laser (32). With the first voltage source (26), the entire display can be converted into the homeotropic state by producing a forming voltage. With the laser (32), an orientation pattern can be produced in display 12 that can be erased or altered at least partially by the application of the threshold voltage and simultaneous irradiation with the laser (32).
