Abstract:
1. An optical control device that does not use a color filter, the device comprising: a first substrate having a plurality of light output layers; a second substrate with a light transmitting function, positioned opposite to the first substrate; a liquid crystal sandwiched between the first and second substrates, first electrodes, on one of the first and second substrates, for applying multiple scan signals to the liquid crystal for an image display; second electrodes, on the other of the first and second substrates, for applying multiple signal voltages to the liquid crystal for an image display; and a layer with a light polarizing function on the first substrate, wherein: each of the plurality of light output layers corresponds to only one of the first electrodes and is arranged in stripes and extends in the same direction as the first electrodes; and the first substrate, the plurality of light output layers, the layer with a light polarizing function, the liquid crystal, and the second substrate are arranged in this order, and wherein all of the plurality of light output layers shine when a specified time has elapsed such that the liquid crystal between each of the first and second substrates is able to respond to the scan signals and signal voltages to modulate light intensity transmitted therethrough to a desired display intensity after a complete set of data signals for each scan line is transmitted to the first electrodes and extinguishes before a succeeding complete set of data signals for each scan line is transmitted.
