Photosensitive matrix with two diodes per dot without specific resetting conductor

摘要: The disclosure concerns matrices of photosensitive elements. To prevent the need for a resetting light source in using, as dot, photodiode series with capacitor between row conductor and column conductor, dot is proposed, formed by reading diode it being possible to put into forward or reverse conduction. read photoelectrical charges generated, pulse, which makes conductive, applied. then reset potential floating node A, at accumulate, constant starting level, pulse applied, thus making conductive (but this time conduction).
