Abstract

The invention relates to a method for addressing pixels of an optical device, wherein the pixel is activated, and with this, the energy status of that pixel is raised resulting in said addressing of the pixel. The improvement of the method is in that on said pixels to be addressed, a combination of electric and optical effects is applied and the raised energy status being necessary for said addressing is reached by simultaneous presence of said electric and optical effects. At the same time, the invention also relates to an optical device which utilises this method of addressing and which has at least one pixel, the pixel being connected to at least one addressing lead and the lead being connected to an electronic commanding unit. Therein, the improvement according to the invention is in that a photosensitive layer (3) is arranged between the pixel (2) and the addressing lead (4), and the photosensitive layer (3) is electrically insulating in its basic condition and it is electrically leading when in addressed condition by being illuminated by light.
