Abstract: A dot matrix display device includes a pixel redraw control unit and a decoder unit. The pixel redraw control unit generates a gate selection signal identifying an address in one direction, a source selection signal identifying an address in another direction intersecting the one direction, and image data which correspond to a pixel electrode part based on a serial signal including an address signal identifying an address of the pixel electrode part and an image signal supplied to the pixel electrode part. The decoder unit supplies a gate signal which activates a gate signal line corresponding to the pixel electrode part based on the gate selection signal, generates a source signal which activates a source signal line corresponding to the pixel electrode part based on the source selection signal, and supplies the image data to the pixel electrode part corresponding to the activated source signal line.

Abstract: Pixel electrodes in odd-numbered rows and even-numbered rows of a liquid crystal display panel are connected to source lines arranged on the left side of the pixel electrodes and source lines on the right side of the pixel electrodes, respectively. A DA converter switches between whether a potential higher than a common electrode potential is output from an odd-numbered output terminal and a potential lower than the common electrode potential is output from an even-numbered potential output terminal, and whether a potential lower than the common electrode potential is output from the odd-numbered potential output terminal and a potential higher than the common electrode potential is output from the even-numbered potential output terminal. A switch mechanism switches between whether a pixel electrode potential is set using the source line on the left side or is set using the source line on the right side.

Abstract: A power supply IC adjusts the frequency of a clock signal outputted from an EXT terminal such that the voltage inputted into a VFB terminal turns to a desired voltage. The power supply IC outputs a clock signal when the control signal inputted into the OE terminal is turned on. The control unit turns on the control signal only in a period that has a time length obtained by adding a slight allowance time to the period required for completion of pixel charge and turns off the control signal upon lapse of the time length. Thus, the power supply circuit outputs an analog voltage only in an initial part in one horizontal period and outputs no analog voltage in the remaining part of the one horizontal period.

Abstract: A gate driver selects a gate line of an odd-numbered row and a gate line of an even-numbered row subsequent thereto and sets the gate line of the even-numbered row to a selected-period potential with a delay of a predetermined time from a timing when the gate line of the odd-numbered row is set to the selected-period potential. After that, the gate driver sets the potential of the gate line set at the selected-period potential to a nonselected-period potential. A source driver switches polarities of pixels in each column every two rows, and sets potentials of respective source lines to potentials according to image data of respective pixels for one row, while making the polarities of the pixels in adjacent columns opposite to each other.
