摘要： Although portions of electrodes in proximity to a driver IC are covered with an insulating film, part of the electrodes is not covered with the insulating film. Thus, this insulating film absent region functions as an external voltage supply region that receives, from the outside, application of a voltage which is different from an output voltage from a driving unit. When the alignment of the initial state is disarranged, an alignment process is performed by short-circuiting all electrodes of the driving unit and applying a voltage from the outside, through the external voltage supply region, whereby the alignment is restored to the initial state with the driving unit being mounted on a liquid crystal panel.

摘要翻译： 尽管靠近驱动器IC的电极部分被绝缘膜覆盖，但是部分电极没有被绝缘膜覆盖。 因此，该绝缘膜不存在区域用作从外部接收与驱动单元的输出电压不同的电压的外部电压供给区域。 当初始状态的对准不均匀时，通过使驱动单元的所有电极短路并且通过外部电压供应区域从外部施加电压来执行取向处理，由此将对准恢复到初始状态， 所述驱动单元安装在液晶面板上。

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.

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： A display control method of a liquid crystal displaying apparatus for driving a liquid crystal panel comprising two substrates, and a liquid crystal layer therebetween. The driving means includes: pixel electrodes each corresponding to a pixel; and for time-division, emitting an LED (Light Emitting Diode) array for red, green, and blue as a back light within each display period, in synchronization with the on/off operation of the pixel electrodes. Each display period is divided into four. The LEDs in the LED array emit red, green, and blue lights in one of the divided periods. Then, one of the three colors is emitted again. This method solves the problem of the conventional control method for performing time-division color display in a liquid crystal displaying apparatus; namely, the insufficient emission intensity of LEDs makes the intensity of the entire liquid display apparatus insufficient, such that white is seen as somewhat grayish white to the human eye.

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.
