Abstract: A matrix display device comprises a matrix of optically addressable pixels (Pij) which comprise a light sensitive element (LSij) and a pixel light generating element (LGij). The light generating element (LGij) will produce a pixel light (LMij) with a brightness which depends on the state of the light sensitive element (LSij). The state of the light sensitive element (LSij) depends on the amount of light impinging on it. The actual brightness of the pixel light generating element (LGij) may further depend on a voltage across it. The pixels (Pij) are constructed such that a portion of the pixel light (PLMij) generated by the pixel light generating element (LGij) reaches the associated light sensitive element (LSij) of the pixel (Pij). The light sensitive element (LSij) is sensitive to the portion of the pixel light (PLMij) to obtain a feedback of the portion of the pixel light (PLMij) to the light sensitive element (LSij).

Abstract: A matrix display device comprises a matrix of optically addressable pixels (Pij) with a light sensitive element (LSij) which receives data light (Lj) to control a state of the light sensitive element (LSij) depending on the data light (Lj), and a pixel light generating element (LGij) which generates an amount of pixel light (LMij) depending on the state of the light sensitive element (LSij). A select driver (SD) supplies select voltages (SVi) to lines (LRi) of the pixels (Pij), the select voltages (SVi) having a level which does not allow the amount of pixel light (LMij) of the pixel light generating elements (LGij) to be substantially changed for not selected lines (LRi), the select voltages (SVi) having a level which does allow the amount of pixel light (LMij) of the pixel light generating elements (LGij) to be changed for a selected one of the lines (LRi). At least one data light generating device (ALj; LAS) directs the data light (Lj) to the light sensitive element (LSij).
