    摘要: On a matrix form display panel which realizes a display device with a high image quality, the return circuits of condensers, connected to picture elements in the last row among picture elements arranged in a matrix form, are connected to a common line independently of the return circuits of the condensers in the other rows, a common electrode driving circuit is provided, and a common electrode driving voltage is applied, whereby the effective values of driving voltages applied to the picture elements in the last row are equalized to the effective values of driving voltages applied to the picture elements in the other rows. Thereby, all the picture elements forming the panel are equal in optical transmissivity, and as a result the displayed image quality is improved. Additionally, since the last scanning line can be used for displaying, the utility factor of display panel is enhanced.

    摘要: 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.
