GRATING DRIVE CIRCUIT, DRIVE METHOD, AND AUTOSTERESCOPIC 3D DISPLAY

摘要

The present disclosure relates to a grating driving circuit, including: a grating including a plurality of grating elements, each having an on/off state controlled by a grating driving signal; a viewpoint tracker for determining a viewing distance S of a viewer; a plurality of grating control electrodes with each configured to control the on/off state of a corresponding grating element in the grating according to a grating driving signal; a grating driving signal generator for generating a plurality of sets of grating driving signals with each set corresponding to a viewing distance and including a plurality of grating driving signals; and a grating driving controller for determining a set of grating driving signals corresponding to the viewing distance, and forming grating periods corresponding to the viewing distance, each grating period including a plurality of grating control electrodes that correspond to the plurality of grating driving signals in a one-to-one relationship.
