Eye glasses device with liquid crystal shutter and its control method

摘要: PURPOSE: To find that power source is turned on when a switch of glasses by interrupting liquid crystal shutter for fixed period and thereafter opening it. CONSTITUTION: An oscillation circuit 6 starts operation, one chip microcomputer consisting system control 2 becomes regular operation mode from stand-by mode. Further, 10 the 2. Thus, voltage supplied to reception 3 drive 8. At this time, instruction (e.g. signals Sr, Sl are high level also) so parts R, L left/right 5 become closed state (the light transmissivity low) also sent 8 an eye device opened state, user finds on.
