    摘要: A level shift circuit having a latch function includes a precharging PMOS transistor MP1 which is turned on in a precharge period to interrupt a through current of an input stage, an NMOS transistor MN1 which inputs data and performs discharging in a data input period, and a transistor MP2 for holding data after level shifting. Thus, each of the transistors can have a minimum configuration. Since the level shift circuit has a latch function, it is possible to omit a circuit for latching input data, thereby reducing a circuit area.

    摘要: A signal line driving circuit includes an output section outN (where N is a natural number) for supplying an image-forming signal for red, green or blue to a sub-pixel of a display section, a voltage supply line SN connected to the output section outN, and a shorting line for electrically shorting output sections of the same color with each other during a predetermined period. By shorting output sections of the same color with each other, the charge stored in a panel-side load can be effectively redistributed to another panel-side load, thereby realizing a power conserving effect.

    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: If a display is subjected to n line dot inversion drive control, the polarity pattern of sub-pixels is shifted line by line in a cycle of n frames. Furthermore, in every n horizontal scanning periods in which the polarities of output terminals of a source driver are switched, at least two of the output terminals are short-circuited to carry out electrical charge recovery. By using these methods, it is possible to achieve a reduction in power consumption while improving image quality.
