Abstract

The display screen (5) has a plurality of cells (2). Each cell (2) has a pixel (P) for modulation of light from a light source (4), a photosensitive device (D) for converting optical display signals (Li) into an electrical signal (I) to control the modulation by the pixel (P), a storage capacitance coupled in parallel to the photosensitive device (D) and a storage reset switch (SR) for providing a storage reset voltage (VR) to the storage capacitance.
