Abstract
A display device operating in accordance with the reset principle provides an array of pixels formed by an array of picture electrodes on the facing surfaces of two substrates with an electro-optical display medium therebetween. A matrix of row and column electrodes apply selection and data signals to the pixels and a system of auxiliary electrodes arranged parallel to the column electrodes apply an auxiliary voltage to the pixels prior to the selection signals. The picture electrodes are electrically coupled to the column electrodes and to the auxiliary electrodes via a plurality of first and second switching units, respectively. The first and second switching units are arranged perpendicular and parallel, respectively, to the column electrodes whereby artifacts are prevented while a larger effective surface area of the pixels is also obtained.
