ABSTRACT:
An eyewear type viewer having left and right LCD panels for the left and right eyes is arranged so that both LCD panels are driven and controlled by a single LCD drive circuit and a single timing control circuit, to reduce the weight and cost of the viewer. The timing control circuit controls the timings of the left and right LCD panels synchronously by sending a common timing control signal to both of the left and right panels, or controls the left and right panels individually by producing a first timing control signal for the left panel and a second timing control signal for the right panel. The timing control circuit may include a comparator which receives a composite control signal composed of a first component representing a write/hold signal, and a second component representing a quasi vertical synchronizing signal, and which separates the write/hold signal from the quasi vertical synchronizing signal.
