LCD matrix for computerised light transmission control e.g. for office or TV illumination - has transparent passive transducer elements of different size, thickness and shape applied to surface with e.g. colour layers and optical and thermal sensors.

摘要

The transducer matrix allows the position, the intensity and the colour tone of the light passed through a transparent object of large surface area, e.g. a window pane, to be regulated. The transducer elements are integrated in a matrix layer (1) applied to the surface of the object and controlled via a microprocessor. Pref. the passive optoelectronic transducer elements have differing sizes, shapes and thicknesses, with a number of separate or overlying layers. USE - For providing test pattern on LCD image screen or monitor, for controlling light entering building, through windows, for photography, film or medical radiation therapy and diagnostic appts..
