A combined image sensor and display device comprises an array of device elements (18), each of which comprises a display pixel (M4, C2, CLC). The display pixels have data inputs connected to column data lines (SL, 6,6'). The array includes sensor elements (10), each comprising a transistor (M1), an integrating capacitor (C1) and a photodiode (D1) connected together to an integrating node (11). The transistor (M1) is connected between column data lines (6,6'). The capacitor (C1) is connected to a control input (RS) which receives a first voltage during a sensing phase for switching off the transistor (M1) and a second voltage during a reading phase for enabling the transistor (M1).
