Abstract

See full text

A color matrix display unit which has a screen having at least three sets pixels, all pixels in a same one of the three sets being of the same color among red, blue and green and all said pixels of a same one of said sets being distributed in a matrix arrangement comprising rows and columns. A plurality of column conductors each simultaneously addresses all pixels in a same column. A plurality of row conductors each simultaneously addresses all pixels in a same line. Each column conductor allocated to red or blue pixels addresses an overall pixel area that is about double the overall pixel area addressed by one of the column conductors allocated to a green pixel. A drive circuit connected to the column conductors addresses the green pixels with a time or space repetition period which is half the period for red and green pixels.
