LIGHT EMITTING DISPLAY DEVICE WITH MECHANICAL PIXEL SWITCH

摘要

A display device comprising a first and a second set of electrod es (2, 5), and a plurality of light-emitting elements (3), arranged between said sets of electrodes. The display further comprises an electromechanically operable foil (6), located between said light-emitting elements (3) and said second set of electrodes, with a conducting layer facing the light-emitting elements (3). The foil (6) is arranged to place the conducting layer (7) in contact with selected ones of said light-emitting elements (3), thereby closing a circuit from said first set of electrodes (2), via said elements (3), to said conducting layer (7). Thus, the foil acts as a plurality of "switches", connecting selected light-emitting elements to the conducting layer. This function can be used for controlling the light-emitting elements with a higher degree of accuracy.
