Tohoku Univ. Technology: High-Resolution Liquid Crystal Spatial Light Modulators for Electronic Holography : T23-075
Realizing wide viewing-zone angles For electronic-holography 3D displays
・ Electronic holography for displaying three-dimensional (3D) information is required for entertainment, industrial design, measurement, and head-up display for automobiles. ・3D information is displayed by reconstructing an image through a spatial light modulator(SLM). SLM cannot narrow the pixel pitchbecause the electric field leaks out to adjacent pixels, resulting in a narrow viewing-zone angles. ・Therefore, the invention introduces a liquid crystal driving system in a lateral electric field by a continuous potential difference and fine ground electrodes into the SLM. ・As a result, the electric field leakage is reduced, the pixel pitch of less than 1 μm is achieved for the first time. ・Using the pixel pitch of 1μm, it is possible to achieve practical viewing-zone angels of 30°. invention is expected to enlarge electronic holography application field.
