Latest Patents

Nakamura’s listed patents address display control and usability in wearable viewing devices.

- **Liquid crystal display system.** This invention describes an eyewear-type viewer with separate LCD panels for the left and right eyes, controlled by a single LCD drive circuit and timing control circuit. Sharing these components is intended to reduce the viewer’s weight and cost. The timing circuit can synchronize both panels using a common signal or control them independently with separate signals. It may also use a comparator to separate write/hold and quasi-vertical-synchronization components from a composite control signal.

- **Head-mounted image display apparatus.** This eyeglass-style apparatus uses left and right shutoff switches to support focus and width adjustments. When one switch is operated, the corresponding LCD displays a black image while the other displays a test pattern, allowing adjustment without external input or the need to keep one eye closed. The apparatus also includes audio earphones, a circuit that detects three-dimensional image signals, and surround-audio processing activated by those signals.
