摘要： An edge image extraction light modulator forms an edge portion image corresponding to a boundary between two optically equalized portions of a liquid crystal layer. Each portion has a different bistable state and an edge portion optically distinct from the two optically equalized portions. An optical image is written onto the light valve while applying a voltage between two transparent electrode layers of the light valve to effect switching between a first stable optical axis and a second stable optical axis. The light valve is illuminated and the edge portion of the written image is read. A first and a second polarizer are in crossed-Nicols position so that the two optically equalized portions comprise a portion having the written image except for the edge portion thereof and a non-written portion. The edge portion is not optically equal to the two optically equal portions and can thus be detected. A method of driving the edge image extraction light modulator includes writing an optical image onto the light valve by irradiating a photoconductive layer with light. A first pulse voltage is applied to erase and reset the light valve, and a second pulse voltage is applied, having a polarity opposite that of the first pulse voltage, to generate carriers diffusing in the photoconductive film to impart an electric field to the liquid crystal layer and form an enlarged image of the optical image in the light valve. A third pulse voltage, having the same polarity as that of the first pulse voltage, erases a part of the enlarged image except for an edge portion thereof to form an edge enhanced image in the light valve.

摘要： The present invention is concerned with point/output characteristics of a light input image having density gradation using a light writing type light valve comprising a combination of a hydrogenated amorphous silicon photoconductor and a ferroelectric liquid crystal. More specifically, the invention relates to a method of expressing continuous gradation using a light writing type ferroelectric liquid crystal light valve that has been difficult to realize. The expression of continuous gradation is made possible by superposing a DC bias voltage of from 0.1 V to 10 V on a rectangular-wave voltage or a bipolar pulse voltage that has theretofore been used as a driving voltage in order to strongly couple together the spontaneous polarization of ferroelectric liquid crystal and the polarity of the DC voltage, and by eliminating the bistability exhibited by the ferroelectric liquid crystal while developing a monostable condition.

摘要： In order to prevent signal distortion using a multiple line selection driving technique when using pulse width modulation to achieve a half-tone display in a liquid crystal display panel, respective bits of column signals are arranged in a descending pulse width order and a voltage generating circuit is used to lower level differences in adjacent bits. An orthonormal function generating circuit generates a plurality of row signals to drive a group of row electrodes through a vertical driver. A dot product computation circuit computes a dot product of the orthonormal functions and pixel display data to generate a column signal in the above manner. A horizontal driver applies the column signal to a group of column electrodes. Pixel data is stored in a frame memory, each datum being represented by a series of bits corresponding to a gray scale. The dot product computation circuit divides the pixel data into the respective bits, and individually carries out the dot product computation for each bit. The horizontal driver arranges the column signal components in order of descending pulse width. A voltage level circuit lowers the voltage level between the column components to reduce distortion caused by the high switching speed between the components and the low response time of the liquid crystal material.
