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： In a matrix display device, a signal drive circuit comprises selection means for sequentially selecting at least one of display information signals corresponding to a plurality of signal electrodes when at least one of a plurality of scan electrodes is selected, hold means for holding the display information signal selected by the selection means until selection of at least corresponding scan electrode is completed, and voltage conversion means for selecting one of a plurality of voltage levels in accordance with the display information signal held by the hold means and supplying the selected voltage level to the signal electrodes. Since the display information signal is held by the hold means until the selection of at least corresponding scan electrode is completed, one of the plurality of voltage levels is always applied to the signal electrodes and the switching elements do not assume the high impedance state. Accordingly, ununiformity in display image is prevented and a large size matrix display device is provided.

摘要： In a liquid crystal display in which the region around a display region is reduced, a black matrix BM is made of a colored organic resin. Substantially all over the periphery of a seal member SL, there are formed portions in which the seal member SL and the black matrix BM are and are not overlapped. A shielding tape TAPE is stuck to that portion of the lower face of a lower transparent glass substrate SUB1, which corresponds to the non-overlapped portion, to prevent the leakage of light from the seal portion.
