摘要： A driving device for driving an image display system, which sequentially receives input image data corresponding to gradation of each pixel of a display image and outputs a driving voltage signal includes: an operation section for obtaining output image data of which a bit number is smaller than a bit number of the input image data based on input image data of a target pixel to be processed and input image data of a pixel in vicinity of the target pixel; a reference voltage generation section for generating a plurality of reference voltages of different levels; and a reference voltage selection section for selecting one of the plurality of reference voltages. The operation section is configured to obtain output image data of the target pixel so that a difference between the input image data and output image data of the target pixel and a difference between the input image data and output image data of the pixel in vicinity of the target pixel cancel out each other.

摘要： A time required for an output voltage of a source follower to rise from Low to a predetermined voltage depends on a bias voltage. Therefore, by setting a converged voltage of an output voltage to be high by increasing the bias voltage, the time required to rise up to the predetermined voltage can be reduced. Therefore, a first source follower which is biased so that the converged value of the output voltage becomes a predetermined Hi voltage when an input data signal goes from Low to Hi, and a second source follower which is biased so as to become the Hi voltage after a period of one clock when an input data signal goes from Low to Hi, are used. The two source followers are operated with appropriate timing.

摘要： A delay element generates a delayed clock signal which transitions with a delay from a rising (or falling) of a reference clock signal by a delay amount determined based on an output of a loop filter. A signal generation circuit generates two signals which complementarily change according to rising and falling of the reference clock signal and a transition of the delayed clock signal. A charge pump circuit performs on the loop filter, according to these two signals, a push (or pull) operation during an interval extending from a rising (or falling) of the reference clock signal to the transition of the delayed clock signal and a pull (or push) operation during an interval extending from the transition of the delayed clock signal to a falling (or rising) of the reference clock signal.
