Estimating the term…
A matrix display comprises a matrix of optically addressable pixels (Pij). The pixels (Pij) comprise a light sensitive element (LSij) having a state depending on a brightness of control light (Lj) impinging on it. The pixels (Pij) further comprise a pixel light generating element (LGij) for generating pixel light (LMij) with a brightness depending on the state of the light sensitive element (LSij). The matrix display device comprises a sheet of transparent material (TS) positioned in front of the matrix of pixels (Pij), and a light source (LS) which couples source light into a side of the sheet of transparent material (TS). In use, the source light is substantially totally internally reflected in said sheet (TS). The control light (Lj) leaves the sheet (TS) at positions where the sheet (TS) is locally disturbed. This control light switches or changes the brightness of the pixels (Pij) at these positions, or provides touch position information.
