<p>An active matrix electrophoretic display device comprises an array of rows and columns of display pixels. Each pixel comprises a plurality of sensors for detecting movement of the electrophoretic display particles, different sensors detecting particle movement which reaches different regions within the pixel. The invention uses multiple in- pixel sensors, and determines the pixel optical state by using a relationship between the sensor outputs which is independent of ambient light. In this way ambient light compensation is carried out simultaneously with the addressing of the pixel, and without requiring dedicated ambient light sensors.</p> |
