초록 ▼

An active flat-design video screen is described, having signal line means arranged in lines and columns, these signal line means, at their crossing points, defining picture elements of the video screen, in which case the lines that are arranged in columns are developed as electrodes and the signal line means that are arranged in lines are developed by means of optical waveguides into which, on the input side, a modulated light signal is coupled and which, at each crossing point, have a device for the coupling-out of the respective light signal. In comparison to conventional active flat-design video screens, the video screen according to the invention distinguishes itself particularly by a good picture resolution and a good contrast range, connected with a good regeneration rate.

대표청구항 ▼

An active flat-design video screen comprising: signal line means, arranged in groups of lines and columns, which, at their crossing points, define picture elements of the video screen; a control and signal processing means for controlling picture information supplied to the signal line means; light element means for emitting modulated light, which is modulated corresponding to the picture information, wherein one of the groups of signal line means is formed by optical waveguides having an input side into which the modulated light signal is coupled; coupling-out means at each of the crossing points, and responsive to said control and signal processing means, for coupling-out an optical signal in said optical waveguide, in a direction extending substantially perpendicular with respect to a plane of the video screen, and for coupling-out light from the optical waveguides in the area of each individual picture element as a function of said control and signal processing means of another group, other than said one group, of signal line means.
