    摘要: The display device includes display drivers including first and second ones operable to output, based on display data, gradation signals to source lines of display panel regions. The display device is arranged to be able to suppress the variation in output voltage between display drivers while minimizing the increases in chip area of the display drivers and in wiring area of a display panel and keeping high noise resistance. Each display driver can generate gray scale reference voltages for producing gradation signals corresponding to display data. The first display driver can sequentially transmit gray scale reference voltages generated by itself to the second display driver. Based on the transmitted gray scale reference voltages, the second display driver makes the first display driver execute calibration for decreasing the absolute value of difference between gray scale reference voltages generated by the first and second display drivers, or executes the calibration by itself.

    摘要: A display device is arranged so as to be able to conduct a touch detection action for sensing a region where a touch operation on a touch panel has been performed, to stop the touch detection action in the touch panel, and to specify a touch-detection-stop region. The display device includes an image-display-direction register. A processor writes parameters designating an image-display direction into the image-display-direction register based on a result of detection by a tilt detector. On condition that parameters stored in the image-display-direction register have been changed, the display device changes the touch-detection-stop region based on the parameters. The above function is mounted on a semiconductor integrated circuit device included in the display device.
