摘要： After rewriting the displayed image by applying a voltage corresponding to desired image data to a ferroelectric liquid crystal through TFTs at a predetermined cycle, the application of voltage to the ferroelectric liquid crystal is stopped, and the image displayed just before stopping the application of voltage is retained. In this memory display period, a gate-off voltage is applied to turn off the TFTs. In this memory display period, the emission intensity of a back-light is lowered compared to that in a normal display period. Before stopping the application of voltage to the ferroelectric liquid crystal, a voltage corresponding to an image to be displayed after stopping the application of voltage is applied. Before resuming the application of voltage corresponding to the image data to the ferroelectric liquid crystal, a voltage for causing all pixels to display black image is applied.

摘要： A voltage corresponding to desired image data is applied to a ferroelectric liquid crystal having a spontaneous polarization at a predetermined cycle to rewrite the displayed image (period A), and then, all voltages applied to the ferroelectric liquid crystal are removed (timing C) to retain the displayed image before the removal (period B). A gate selection period (voltage application period to the ferroelectric liquid crystal) t2 before stopping the voltage application is set longer than a gate selection period (voltage application period to the ferroelectric liquid crystal) t1 in the normal display. Increasing the voltage application period to the ferroelectric liquid crystal provides a sufficient response of the liquid crystal during the gate selection period, thereby realizing high memory ability.

摘要： In a sub-frame of each color, the time required for each data scanning is 25% of the sub-frame, and the time between two times of data scanning is also 25% of the sub-frame. In a sub-frame of each color, a back-light is turned on between the intermediate timing in the first (first-half) data scanning and the intermediate timing in the second (second-half) data scanning. The ON time of the back-light is 50% of the sub-frame, and the ratio of time (panel ON rate) in which a liquid crystal panel is in a transmission state (ON) to the time in which the back-light is turned on is 88%, and thus high light utilization efficiency is achieved.

摘要： A liquid crystal panel includes a glass substrate with pixel electrodes that are arranged in a matrix shape, TFTs that are connected to the pixel electrodes, and a glass substrate with an opposing electrode and color filters that are arranged in a matrix shape. A liquid crystal layer is formed in a space between the glass substrates by filling a ferroelectric liquid crystal into the space. When writing display data, and when deleting display data that has been written, a voltage, not including 0V, that becomes a voltage potential, or in other words, a voltage that is greater than a threshold voltage at which the optical characteristic of the filled ferroelectric liquid crystal changes is applied between the opposing electrode and pixel electrodes. An image is displayed over all gradation numbers, including the low-gradation side, and the display characteristic is improved.

摘要： In a field sequential display method the light emission intensities of the luminous colors are controlled to realize a plurality of color reproduction regions having different areas and make the color purity variable. In the case of high-resolution image display, a first control method is adopted in which in synchronism with the input of the pixel data of one of the luminous colors, the light of the one of the luminous colors is emitted and the lights of the other luminous colors are not emitted. In the case of coarse image display, a second control method is adopted in which in synchronism with the input of the pixel data of one of the luminous colors, the light of the one of the luminous colors and the lights of the other luminous colors are emitted. By the second method, the color purity is slightly decreased to suppress the visual irritation.

摘要： A liquid crystal display device comprising: a peripheral electrode 31 that is formed around the outside of a display region 1a on a liquid crystal panel 1 and that generates an orientation state that is equivalent to that of the display region 1a; and an inverted electrode 32 that is formed around the outside of the peripheral electrode 31 and that generates an orientation state that has polarity opposite to that of the display region 1a; wherein the peripheral electrode 31 and the inverted electrode 32 have bipectinate construction and are arranged on both sides of a non-oriented buffer region 33. Orientation defects that are generated in a seal are trapped inside the buffer region 33 due to the existence of the peripheral electrode 31 and inverted electrode 32 that have different growth directions, so the orientation defects do not intrude into the display region 1a.
