摘要： A high-speed scanning method uses a K(K.gtoreq.3)-number of semiconductor switch elements each having a first main electrode responsive to an input signal, a second main electrode, and a control electrode responsive to a control signal for controlling the transmissive and intransmissive states of said input signal from the first main electrode to the second main electrode; and capacitive loads connected respectively with the second main electrode of each of said K-number of semiconductor switch elements, for shifting one of the K-number of semiconductor switch elements sequentially with a predetermined period from the transmissive state to the intransmissive state or vice versa, wherein, the time, for which an arbitary L(K>L.gtoreq.2)-number of semiconductor switch elements of adjacent scans are rendered transmissive, and the time, for which the L-number of semiconductor switch elements are rendered intransmissive, are included in at least one frame period, to elongate the period for which the scanning signals fluctuate, thereby permitting use of low-frequency semiconductor switches.

摘要： 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.

摘要： A reflective-type display device having a light modulating layer, including a host dispersed with light scatterers, which is held between two transparent electrodes; and a light absorbing layer disposed in back of the light modulating layer. The size of each light scatterer or the nearest distance between the adjacent light scatterers is nearly equivalent to the wavelength of incident light at least in two-dimensional directions. The refractive index ratio relative to incident light between the light scatterers and host is changed from 1 to 1.5 or more depending on the magnitude of a voltage applied across the electrodes.

摘要： A liquid crystal active matrix display device includes a first substrate having a thin film transistor formed thereon. A light-screening film 1 is located on the first substrate in a manner to be overlapped with an ITO. The display device includes a second substrate having a color filter and a light-screening film 2 formed thereon. The second substrate is opposed to the first substrate. The light-screening film 2 extends from the uncontrollable area by a certain value depending on a voltage from the external, resulting in improving a numerical aperture.

The display circuit for generating the display voltages is composed of an image signal processing circuit for dividing an input digital image signal into plural bit groups, a first display voltage generating circuit for generating the display voltages corresponding to the first bit group obtained by the division, a second display voltage generating circuit for generating the display voltages corresponding to the second bit group obtained by the division, and a line-at-a-time timing circuit. The first and second display voltage generating circuits are operated in parallel to combine the outputs thereof with one another, thereby to generate a gray scale displaying voltage.

The region where the display condition is to be erased is designated in the liquid crystal display panel. The X and Y electrodes in that region are impressed with the X electrode non-selecting voltage, the other Y electrodes are impressed with the Y electrode selecting voltage, the other X electrodes are impressed with an erasure holding voltage having a continuously repetitive pulse waveform including one cycle of the Y electrode non-selecting voltage and three cycles of Y electrode selecting voltage, so that the liquid crystal cells in the designated region are supplied with the erasure voltage and the other liquid crystal cells are supplied with the holding voltage, thus erasing the designated region alone.
