Abstract
A matrix-display panel such as a liquid crystal display panel is composed of row and column electrodes and liquid crystal interposed between both row and column electrodes. Pixels formed at each intersection of the electrodes are driven by imposing composite voltages consisting of scanning voltages supplied to the row electrodes and image data voltages supplied to the column electrodes. Pixels aligned along one row electrode are alternately connected to two or three neighboring row electrodes in a zigzag manner, and an interlaced scanning is performed by jumping one or two row electrodes at a time, thereby reducing a flicker frequency to an invisible level and making a line-scroll invisible. The pixels may be driven by switching a transistor connected to each pixel.
Claims2
A matrix-display panel comprising:
- n row electrodes;
- m column electrodes disposed perpendicularly with respect to the n row electrodes;
- an electro-optical material disposed between the row electrodes and the column electrodes;
- and
- n×m pixels formed at each intersection of the row and column electrodes together with the electro-optical material, the pixels being arranged in a matrix, wherein:
- each pixel is divided into a pair of sub pixels;
- each sub pixel includes a pixel electrode and a semiconductor switching element having a gate electrode for selectively supplying voltages to the sub pixel electrode;
- and
- gate electrodes of switching elements corresponding to a pair of sub pixels located along a row electrode are connected to the row electrode, and gate electrodes of switching elements corresponding to a subsequent pair of sub pixels located along the row electrode are connected to an adjacent row electrode, so that all subpixel pairs are connected to the row electrodes in an alternating manner.
