ELECTROLUMINESCENT DISPLAY DEVICES

摘要

An active matrix display device has pixels each with a light-sensitive device (84) for optical feedback functions. Each pixel has a light blocking structure (100) formed from the thin film layers of the display substrate in the proximity of the light­-sensitive device (84) and substantially at the level of an input surface of the light sensitive device. This structure prevents the passage of light (g) to the light­ sensitive device from a substantially lateral direction.
