The disclosure relates to a projector having an arrangement of polarizers and liquid crystal cells aligned on the axis of light in the order a first color polarizer colored in red, a first twisted nematic liquid crystal cell, a second twisted nematic liquid crystal cell, a second color polarizer colored in a green, a third twisted nematic liquid, a neutral polarizer and Guest-Host type colored in blue. Since, according to this, a polarizer having inferior color characteristics can be replaced by a Guest-Host type liquid crystal cell, the excitation purity and the scope of color reproduction are improved. Further, since the mixture of color is additive, the brightness of the reproduced color is also much improved.
摘要:
The liquid crystal is written with a laser beam. The laser beam generated by a laser source is applied through an optical control unit such as galvanometer mirrors to the liquid crystal. The intensity of the laser beam applied to the liquid crystal is controlled by a laser beam intensity varying unit. A writing control unit controls the mechanical displacement caused by the optical axis control unit and controls the laser beam intensity varying unit. The laser beam energy applied to the liquid crystal can be maintained constant, thus enabling a constant written line width even during acceleration and deceleration of the optical axis control unit.

The present invention prevents a moiré generated by the interference of two liquid crystal display panels in a display device capable of performing a three-dimensional display using two liquid crystal display panels. By arranging an upper lens array and a lower lens array between an upper liquid crystal display panel and a lower liquid crystal display panel, a moiré and smearing of an image can be prevented. Due to such a constitution, lowering of brightness and contrast can be suppressed.

A gray scale display, which is provided with a liquid crystal panel consisting of switching elements and a liquid crystal layer superposed thereon; a digital-time function transforming device for transforming digital signals including gray scale information into time function signals; and a time function-gray scale transforming device for sampling a brightness reference signal varying with respect to time, responding to the time function signals and generating gray scale signals corresponding to the signal voltage applied to the switching elements. The time function-gray scale transforming device, in which the brightness reference signal is inputted, samples the signal, responding to time function signals such as a pulse phase signal, a pulse width signal, etc., to obtain a signal voltage. In this way it is possible to reduce the size of a signal voltage generating circuit and to lower signal speed of the operation of the circuit.
