    摘要: The present invention aims to provide a monolithic driver-type display device capable of reducing circuit scale of a sampling circuit, and keeping low power consumption by directly driving a source driver with an externally provided video signal.In the monolithic driver-type display device having a display portion for displaying video and circuits for driving the display portion formed on the same insulating substrate, a plurality of sampling switches are provided in association with a plurality of pieces of bit data contained in externally inputted digital video signals. The sampling switches are opened/closed based on sampling signals, thereby sampling the digital video signals for each piece of the bit data and converting the signals into parallel format for output to data lines. The outputted digital video signals charge parasitic capacitances on the data lines and are held therein.

    摘要: A memory-type liquid crystal display device includes transistors (N1, N2), retention electrodes (MRY), refresh output control sections (RS1), and capacitors (Cb1). In a data retention period, an electric potential of each of the retention electrodes (MRY) is changed via a corresponding one of the capacitors (Cb1) by changing an electric potential level of a retention capacitor wire signal that is supplied to a corresponding CS line (CSL(i)). Each of the refresh output control sections (RS1) receives the electric potential thus changed of a corresponding one of the retention electrodes (MRY) via the input section and controls an electric potential of a corresponding pixel electrode (PIX) in accordance with the electric potential thus changed.

    摘要: A memory-type liquid crystal display device includes a liquid crystal panel including memory circuits, and conducts a refresh operation more than once during a display holding period after rewriting of a screen. The memory-type liquid crystal display device increases at least one of (i) a frequency at which the screen is rewritten and (ii) a frequency at which the refresh operation is conducted during the display holding period as an intensity of light received by the liquid crystal panel increases. This allows the memory-type liquid crystal display device to reduce power consumption while keeping its display quality.

    摘要: An object of the present invention is to provide a power supply circuit including a charge-pumping booster section which uses switching elements provided only by N-channel transistors yet does not have a problem of voltage drop by threshold value. In a booster section (11a), capacitors (C1) and (C2) have their respective first terminals connected with transistors (Q1, Q3) and (Q2, Q4) respectively. Each transistor has its gate terminal supplied with control signals generated in a driver section (11b). The driver section (11b) includes capacitors (C3, C4) connected with input terminals (Ti3, Ti4) for respective supply of clock signals DCK2, DCK2B each having a voltage alternating between −VDD and VDD (VDD represents an input supply voltage from outside), as level-shifted signals of clock signals DCK1, DCK1B which are supplied to second terminals of the capacitors (C1, C2) respectively. In this arrangement, the driver section 11b generates signals each having a voltage alternating between VDD and 3VDD, as the control signals.
