LIQUID CRYSTAL DISPLAY SYSTEM

摘要

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.
