  • Patent number: 11355083
    Abstract: [Object] To reduce the amount of data used for performing correction for a display device. [Solution] There is provided a correction device (2) including a correction-value calculation unit (6) that divides a display area of a display device into a plurality of unit areas and that calculates a correction value of luminance for each of the plurality of unit areas, a prioritized-area determination unit (8) that designates each of the plurality of unit areas as one of a prioritized area and a non-prioritized area in accordance with the calculated correction value, a recording unit (10) that records in a memory unit (M) a piece of data of the correction value for the prioritized area, and a correction unit (12) that corrects luminance for the prioritized area in accordance with the piece of data recorded in the memory unit and that uniformly corrects luminance for the non-prioritized area.

  • Patent number: 10984742
    Abstract: A display control device comprises an output unit that outputs an inverted polarity of an AC signal in a constant cycle, based on a signal of the constant cycle; a stop control unit that stops the reversal of the polarity of the AC signal in the output unit, based on a stop signal; a rewrite control unit for outputting a display data rewrite signal; and a transmission control unit for controlling the rewrite control unit. The stop signal stops the reversal of the polarity of the AC signal during a period in which the display data rewrite signal is output. The AC signal stopped by the stop signal maintains a polarity before the stop of polarity reversal. The output unit inverts and outputs the polarity of the AC signal, based on the signal of the constant cycle, after a period in which the display data rewrite signal is output.

  • Patent number: 10937349
    Abstract: [Object] To realize a drive circuit where settling time (stabilization time) is shortened, without incurring marked increase in electric current consumed and marked increase in manufacturing costs. [Solution] A source drive circuit (1) has a digital gradient input converter (2) that converts gradient values of multiple image data (D1 through Dn) that are gradient 1 into multiple gradient values, where the number of the multiple source amps (AM1 through AMn) to which a gradient reference voltage (V1) corresponding to gradient 1 is supplied, is reduced, and supplied to a DAC circuit (23).

  • Publication number: 20190108150
    Abstract: A semiconductor device in which, in principle, plural interrupt request signals can be inputted to a single interrupt terminal is provided. In the semiconductor device, peripheral devices output interrupt request signals of mutually different waveforms. When an interrupt request signal outputted from one of the peripheral devices is received, a microcomputer unit identifies the one of the peripheral devices based on the waveform of the received interrupt request signal. When an interrupt request signal is outputted from any one of the peripheral devices, the interrupt request signal is also inputted to the other ones of the peripheral devices. When one of the peripheral devices receives an interrupt request signal outputted from another one of the peripheral devices, the one of the peripheral devices can output an interrupt request signal of its own only after elapse of a predetermined output inhibition time.

  • Patent number: 6271685
    Abstract: A semiconductor integrated circuit includes a pass transistor logic circuit and an output buffer. The output buffer compensates for an output level of the pass transistor logic circuit. Preferably, the output buffer includes a bootstrap circuit with a capacitor. The capacitor is preferably connected between a gate of an output transistor and an output terminal. Such an arrangement allows for the obtaining of a high voltage at the output terminal.
