摘要： Provided is a touch sensor panel which can increase the detection sensitivity of a touch relatively readily. The touch sensor panel controller supplies drive electrodes of a touch sensor panel with a high-voltage AC drive signal with its low level set to a negative voltage and drives them. The time of change of a drive waveform supplied to the drive electrodes of the touch sensor panel is shifted relative to the time of change of a drive waveform supplied to a display scan electrode. The touch sensor panel controller uses a charge pump in synchronization with clock signals of more than one phase to produce a high drive voltage to activate drive electrodes of the touch sensor panel, and the clock signals of more than one phase are initialized each time the drive electrode is subjected to AC pulse driving.

摘要： Overdrive over multiple frames is made more efficient in a display device drive circuit that drives a display device so slow in response that target brightness is not reached even after overdrive is performed for one frame. When a display gray scale is changed from a first gray scale to a second gray scale, a display driving device varies overdrive driving voltage according to the number of frames since the point of time of the change. This makes it possible to obtain high-speed luminance response. When the number of frames for which an identical image is continuously displayed is known beforehand, the number of frames is set in a display pattern setting register and a function of detecting timing of a change of images is provided. This enables efficient overdrive. At low temperature, further, a display image is updated once for several frames according to temperature information. This enhances the visibility of the image.

摘要： In a display device such as a liquid crystal display, a processing for compressing a range of display data (grayscale) to a low grayscale side (a grayscale range where response is fast) except for a high grayscale side (a grayscale range where response is slow) at a predetermined compression ratio to conduct display according to response characteristic of transition between grayscales and a temperature state and a processing for increasing a light amount of a backlight to compensate for luminance change due to the compression are performed, for example, in a liquid crystal panel of TN liquid crystal. Thereby, response can be made fast even at a low temperature time.
