Active matrix display device and scanning circuit |
摘要 |
An active matrix display device has a number of pixels arranged in matrix form, signal lines for supplying display signals to the pixels, and a driver circuit for driving the signal lines. The driver circuit includes a frequency divider circuit for frequency-dividing input multi-phase clock signals, a synchronous counter circuit for frequency-dividing part of the input multi-phase clock signals, and a decoder circuit for selecting a desired one of the signal lines based on outputs of the frequency divider circuit and the synchronous counter circuit.
