    摘要: A liquid crystal layer is formed by filling a space between alignment films provided on both glass substrates with a ferroelectric liquid crystal material having a spontaneous polarization. This ferroelectric liquid crystal exhibits a monostable state in which the average molecular axis of the liquid crystal molecular director is present in substantially one direction in the absence of an applied voltage. When a voltage of a first polarity is applied, the average molecular axis tilts from the monostable position to one side at an angle corresponding to the magnitude of the applied voltage, while, when a voltage of a second polarity having the opposite characteristic to the first polarity is applied, the average molecular axis tilts from the monostable position to a side opposite to the application of the voltage of the first polarity. A maximum tilt angle in the application of the voltage of the first polarity is not less than 35°, more preferably not less than 450°. With the use of a liquid crystal material having a large spontaneous polarization, a high-speed response is realized even when the applied voltage to the liquid crystal material is low.

    摘要: When a photopolymerization compound (molecular weight: not less than 300) having at least two ultraviolet light sensitive portions in its molecular structure is mixed with ferroelectric liquid crystal and an exposure to ultraviolet light is performed, a continuous structure is formed over almost whole length between two glass substrates, and a continuous twisted structure is formed between the glass substrates in the state of liquid crystal molecular orientation. Before the exposure to ultraviolet light, the photopolymerization compound does not exhibit satisfactory compatibility with the ferroelectric liquid crystal to be mixed, but exhibits phase separation in the mixed state. The ferroelectric liquid crystal has a bookshelf layer structure.

    摘要: In a liquid crystal display device which is constructed by sealing a liquid crystal having spontaneous polarization in an active matrix panel including a coloring member and displays an image on a frame by frame basis by repeating a data writing process and a data erasing process for the active matrix panel, the frequency in the data writing process is set at least twice higher than a frame frequency and the data writing process and the data erasing process are completed within one frame time so that time taken for transmission of light through the coloring member is not more than a half of one frame time. The coloring member is in a non-light-transmitting state during a period of not shorter than a half of one frame, and the blurred outline section of a moving image is reduced.

A back light disposed at the back of the liquid crystal panel and guides red, green, and blue light to the surface thereof; an image memory for storing pixel data PD to be displayed on the respective pixels; an inverted data generating circuit for generating inverted pixel data #PD of the respective pixel data PD; and a control signal generating circuit and a data driver wherein first scanning for writing the pixel data PD with respect to individual pixels of the liquid crystal panel during each period in which red, green, and blue light are emitted in time-sharing manner, and second scanning for writing the inverted pixel data #PD with respect thereto are carried out in this order. Such problems that crosstalk occurs easily, besides response speed thereof is comparatively slow, so that it is not suitable for display of moving picture despite manufacturing cost of STN type display unit is comparatively inexpensive, while because TFT-TN type display unit requires a highly luminous back light, its power consumption is high, viewing angle is narrow, adjustment is difficult in color balance and the like are solved.

    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.
