Abstract

The object of the invention is a method for transmission of visual information, wherein the organs (20) transmitting visual information from the source of information are connected with a first surface for transmitting information and a second surface for illustrating information, whose opposite outer surface most preferably forms a display surface, such as a picture screen, a display screen, an optic surface, or the like. An optically anisotropic medium, such as a liquid crystal or the like, is arranged between the said first and second surfaces. For application of the method, a closed structure is formed, in which preferably essentially plane-like said first and second surfaces are located preferably essentially in the same direction in a housing (70) or the like. The said structure is also fitted with organs for condensing the structure and organs for separating the said surfaces from each other. The method can be applied in television sets, video displays, computers, control devices and other electronic devices for display of pictures on one hand and for converting the pictures into electronic form on the other hand. The said organs (20) transmitting visual information are arranged to function optically, i.e. by means of light beams reflected from an illuminator. The said structure is arranged to be affected by organs controlling the transmission of information from between the said surfaces, whose function is at least partly based on changing the refractive index of the said medium mechanically, or acoustically.
