Latest Patents

One of Torizuka’s latest patents, “Liquid Crystal Display System,” describes an eyewear-type viewer with separate LCD panels for the left and right eyes. A single LCD drive circuit and timing control circuit operate both panels, helping reduce the viewer’s weight and cost. The timing circuit can synchronize the panels using a shared signal or control them independently with separate signals.

The patent also describes a comparator that separates a write/hold signal from a quasi-vertical synchronizing signal within a composite control signal. This supports the timing control of the display panels.

Another patent, “Head-Mounted Image Display Apparatus,” concerns a display designed to be worn like eyeglasses. Its left and right shutoff switches allow a user to display a black image on one LCD while showing a test pattern on the other. This arrangement helps users adjust focus and image width without external input or keeping one eye closed. The apparatus also includes audio earphones, a circuit that detects three-dimensional image signals, and surround-audio processing that operates in response to those signals.

Career Highlights

Torizuka’s listed inventions focus on head-mounted displays and liquid-crystal display systems. The described features address practical design considerations, including device weight, cost, image adjustment, and integration of audio functions.
