active matrix panel

Abstract

Abstract PURPOSE:To make it possible to operate a panel normally when at least one FET per picture element is normal, by providing two FETs per picture element electrode, writing data twice in one frame, thereby providing redundancy. CONSTITUTION:Color filters in red (R), green (G) and blue (B) colors are obliquely arranged in a mosaic shape. TFTs are arranged so as to drive every two picture elements having the same color in the oblique arrangement simultaneously. In the case of a black and white panel or a color panel having longitudinal stripes, the TFTs are arranged so as to drive the two longitudinally arranged picture elements simultaneously. The number of wirings on the Y side can be made twice, and the picture element can be selected one by one. However, the area of the opening for the picture element becomes small, and the wirings become complex. When Y1 is selected, not only the TFTs 1, 2 and 3 on the Y1 line, but also the TFTs 4, 5 and 6, which are connected to the picture electrodes on the Y2 line, are also turned ON. The signals are written in two picture elements at the same time.
