    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: 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.
