HF coupling type controller for display panel - uses array of integrated phototransistors with resonant circuit elements providing light output when one is excited by incident light
The device uses resonance between two coupled resonators in a solid state grid with each point activated by high frequency electromagnetic waves in optical wavelengths. The integrated circuit has each grid point made up of a phototransistor with associated resonant components and these activate an integrated light emitting diode when excited by incident light, giving an amplified light output at a particular point. The device can be used for stationary or moving pictures, controllable displays, and optical control of multiple devices. The columns of the display have the integrated circuit components manufactures so the whole column is responsive to a given frequency and an integral switch transistor associated with each grid row gives access to a partic. point.
