摘要： A load driving circuit that generates a desired voltage waveform to drive a load includes a target voltage waveform output section that outputs a target voltage waveform to be applied to the load. Power supply sections generate electrical power with voltage values different from each other. Negative feedback control sections between the power supply sections and the load supply electrical power from the corresponding power supply sections to the load and execute negative feedback control of a value of a voltage applied to the load for matching the voltage value and the target voltage waveform. A power supply connection section selects one of the power supply sections based on the value of the voltage applied to the load or the voltage value of the target voltage waveform and connects the selected power supply section to the load and disconnects the rest of the power supply sections from the load.

摘要： An aspect of the invention provides an image display apparatus that displays a plurality of input pixels which form input image data on a display section. In that case, each input pixel can be displayed in such a manner that display pixels having gradation values differing from the gradation value of the input pixel are combined. For example, when a pixel having a particular gradation value exists as an input pixel, the pixel is not displayed on the display section as it is being kept at the gradation value, but instead, is displayed in such a manner that a plurality of display pixels having gradation values differing from the gradation value of the input pixel are combined. As a result, the same gradation value is not displayed continuously. Therefore, this results in that the occurrence of crosstalk, which is problematical particularly in a TFD liquid-crystal panel, is reduced. Accordingly, the invention can remove crosstalk which is likely to occur in a TFD liquid-crystal panel by controlling the gradation level of a display image.

摘要： A liquid crystal display device wherein scanning voltages are applied to a plurality of scanning electrodes and signal waveforms are applied to a plurality of signal electrodes. The polarity of the voltages applied to the signal and scanning electrodes is inverted during predetermined periods. As the effective voltage of the display element is changed, correcting voltages are applied to the signal electrodes in order to reduce the contrast problem associated with changes in the effective voltage of adjacent display elements.
