    Abstract: A liquid crystal matrix display device has a plurality of display elements arranged in an X-Y matrix pattern. Vertical transmitting lines are connected to all of the display elements of each column, and horizontal transmitting lines are connected to each of the display elements of each row. Each of the vertical lines is connected through an input switching element to an input circuit to receive a video input signal and a horizontal pulse generator provides sequential pulse signals to control terminals of the input switching elements. In order to improve the resolution without sacrifice of contrast, the vertical transmitting lines are arranged into groups of a predetermined number of such lines, and the input switching elements associated with the lines of each such group have their control electrodes coupled together to a respective output of the horizontal scanning pulse generator. The input circuit includes time-demultiplexing circuitry, for example, formed of sample/hold circuits, to present respective sampled versions of the input signal, staggered with respect to one another, to input electrodes of respective ones of the input switching devices of each of the groups.

    Abstract: A sense amplifier (11) includes two cross-coupled field effect transistors (M1, M2) coupled by capacitors (C1, C2) to respective bit lines (BL2, BL1) from a memory cell. During a precharging operation, the capacitors (C1, C2) are charged to precharged voltages indicative of the threshold dispersion voltage between the two transistors (M1, M2). Thereafter, during a sensing operation, the precharged voltages are applied to the gates (G1, G2) of the transistors (M1, M2) to compensate for the threshold dispersion voltage.

    Abstract: A liquid crystal matrix display device has a plurality of liquid crystal display elements arranged in an X-Y matrix pattern. Vertical transmitting lines are connected to all of the display elements of each column, and horizontal transmitting lines are connected to each of the display elements of each row. Each of the vertical lines is connected through an input switching element to an input circuit to receive a video input signal and a horizontal pulse generator provides sequential pulse signals to control terminals of the input switching elements. In order to compensate for crosstalk that occurs because of parasitic capacitance between the vertical transmitting lines and the liquid crystal display elements, auxiliary lines are provided for the columns of such display elements, and each has a predetermined compensating capacitance relative to its associated liquid crystal display elements. A compensating signal, which is an inverted version of the video signal, is applied in succession to the auxiliary lines to compensate for any crosstalk.

    Abstract: A signal translating circuit is disclosed in which an input signal is supplied to a source follower transistor, a bootstrap capacitive component is presented between the gate and source of the source follower transistor, the signal from the source follower transistor is supplied through a first transmission gate to a next stage, and also led out to an output terminal. Further, the circuit formed of the source follower transistor and the first transmission gate is sequentially connected and the source follower transistor and the first transmission gate are alternately driven with different phases to each other whereby the input signal is sequentially transmitted at each stage. Furthermore, a second transmission gate is connected between the output terminal of the source follower transistor and the ground in which after the output signal at the output terminal rises up and falls down once, the second transmission gate is turned on by the signal relating to the output from the stages following the succeeding stage to thereby make the level of the signal when the output signal at the output terminal falls down stable. Thus, undesired potential fluctuation is not generated on the output line.
