In one embodiment, a display panel driver is provided that includes a dithering section configured to receive first m-bit image data and configured to generate second image data by performing dithering on the first image data with n-bit dither values each selected from elements of a dither table, and a driver circuit configured to drive the source lines of a display panel in response to the second image data. In generating the second image data corresponding to first pixels belonging to a first pixel column, the dither values are selected from elements in a first column of the dither table, while the second image data corresponding to second pixels belonging to a second pixel column adjacent to the first pixel column, the dither values are selected from elements in a second column of the dither table.

摘要： A clock data recovery (CDR) circuit is provided with a circuit that updates a locked oscillation frequency, with a small loop gain, after phase lock based on a phase-locked loop circuit for a frequency-locked frequency is completed by a frequency-locked loop circuit or during a phase lock operation. Since the locked oscillation frequency is updated with a small loop gain, it is possible to correct a fluctuation in a frequency of an oscillation circuit in the frequency-locked loop circuit without oscillating a phase-locked loop undesirably even during a phase lock operation.

摘要： A gate oxide film is formed in a region having a MOSFET on a semiconductor substrate formed therein, and a first polysilicon film serving as a gate electrode of the MOSFET is further formed. Thereafter, a charge storage three-layer film is formed by opening a region having a MONOS type FET formed therein, exposing a semiconductor surface of the semiconductor substrate, and sequentially depositing a first potential barrier film, a charge storage film, and a second potential barrier film. In this case, before the charge storage three-layer film is formed, an anti-oxidation film is formed on the first polysilicon film.

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.
