ABSTRACT:
A matrix-type display device capable of effecting color-displaying is constructed such that the mode of sampling neighboring RGB data can be optionally selected from two modes, e.g., three-point successive sampling mode and three-point simultaneous sampling mode. In the case of the three-point successive sampling mode, since pulses are generated successively so that each pulse is shifted by one-dot term .tau. from one another, the pulse terms of sampling pulses are shifted by one-dot term .tau. from one another. Accordingly, pixel signals supplied to respective three neighboring RGB pixels are shifted by one-pixel equivalent. On the other hand, in the case of the three-point simultaneous sampling, generated pulses all stay at high level at any time. Therefore, the pulse terms of sampling pulses are made coincident, so that pixel signals supplied to respective three neighboring RGB pixels are of data on an identical point.
