  • Patent number: 9922613
    Abstract: In a liquid crystal display device, it is determined whether or not image data inputted from the outside has changed from image data of the previous frame by comparing those image data with respect to each line. As a result, when it is determined that the image data has changed, an entire screen is not rewritten, but image data from a top of a screen as a fixed position to a last line with the image data having changed are read from a frame memory and written into a pixel formation portion. Accordingly, of the screen for one frame, a screen from a top thereof to the last line where the image change has been detected is updated, and on subsequent lines, an image of the previous frame is continuously displayed.

  • Patent number: 9715940
    Abstract: A shift register is configured by connecting unit circuits 1 in multiple stages. An output transistor Tr1 switches between whether or not to output a clock signal CKA in accordance with a gate potential. A set transistor Tr2 switches between whether or not to provide an output of an on-potential output unit 2 to a gate terminal of Tr1 in accordance with an output of a set control unit 3. The set control unit 3 controls a gate terminal of Tr2 into a floating state in part of a period during which a high-level potential is provided to the gate terminal of Tr1. The gate potential of Tr2 is raised by being pushed up, whereby a high-level potential without a threshold drop is provided to the gate terminal of Tr1, and rounding of an output signal OUT is decreased when the output signal OUT shifts to a high level. Accordingly, an operation margin with respect to fluctuation of a threshold voltage of the transistor is increased.

  • Patent number: 9632527
    Abstract: A shift register is configured by connecting unit circuits 1 in multiple stages. An output transistor Tr1 switches between whether or not to output a clock signal CKA in accordance with a gate potential. A drain terminal of an initialization transistor Tra is connected to a gate terminal of the Tr1, and a source terminal thereof is connected to an output terminal OUT or a clock terminal CKA. The source terminal of the Tra is connected to a node which has a low-level potential at the time of initialization and has a potential at the same level as the clock signal when the clock signal having a high-level potential is outputted. Thus, at the time of outputting the clock signal having the high-level potential, application of a high voltage between the source and the drain of the Tra is prevented, and degradation and breakdown of the initialization transistor are prevented.

  • Patent number: 9230496
    Abstract: This display device has a demultiplexer (501) formed on a liquid crystal panel, the demultiplexer including three switching elements SW1 to SW3 for time-division drive, which are connected to video signal lines SL1 to SL3. Here, the number of switching control signal lines for transmitting switching control signals GS1 to GS6 to be provided to switching elements coupled to the video signal lines is six, which is twice the number of time divisions, and switching control signals (e.g., GS1 and GS4) with the same timing are individually transmitted by two switching control signal lines, so that the number of switching elements to be coupled to the switching control signal lines as loads can be halved, resulting in reduced waveform rounding of the control signals.

  • Patent number: 9076400
    Abstract: 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.

  • Patent number: 9070471
    Abstract: Provided is a shift register of a display-driving circuit which carries out simultaneous selection of a plurality of signal lines by using a simultaneous selection signal. A stage of the shift register includes (i) a set-reset type flip-flop and (ii) a signal generating circuit which generates an output signal of the stage by selectively outputting a signal in response to an output of the flip-flop. The output signal of the stage (i) becomes active due to an activation of the simultaneous selection signal and then (ii) remains active while the simultaneous selection is being performed, and the output from the flip-flop is inactive during a period in which a setting signal and a resetting signal are both being active. This makes it possible to quickly carry out the simultaneous selection of all the signal lines and the initialization of the shift register.
