Abstract: A dial indicator display device according has a needle indicator; a needle moving means for moving the needle indicator; a display panel disposed behind the needle indicator and capable of displaying an image; and a drive control means for controlling the needle moving means and driving the display panel. The drive control means includes a scale display control means for displaying a scale in a scale display area on the display panel overlapping the range of needle movement in plan view, a needle position detection means for detecting the position of the needle indicator, and an information display means. The scale display control means segments the scale display area into a scale area and a no-scale area not including the scale area based on the needle position detected by the needle position detection means, and displays a scale for reading values indicated by the needle indicator only in the scale area, and the information display means displays information in the no-scale area.

Abstract: There is provided a method of driving an electrophoretic display device including a display unit that has a plurality of pixels and an electrophoretic element disposed between substrates forming one pair. The method includes setting an area that at least includes a pixel forming an image component that is formed to have a first gray scale and a pixel that is disposed to be adjacent to the pixel forming the contour of the image component and represents a second gray scale as an image removing area and selectively changing the pixels that constitute the image removing area to have the second gray scale.

Abstract: A drive method for an electrophoretic display device that has an electrophoretic device composed of a suspension fluid containing electrophoretic particles disposed between a common electrode and a plurality of pixel electrodes, a driver that drives the electrophoretic device by applying voltage between the common electrode and the plural pixel electrodes, and a controller that controls the driver. The control method has a display redrawing process that changes the displayed image by applying a common electrode drive pulse that repeats two different potentials to the common electrode, and applying either of the two different potentials to the pixel electrodes according to the updated display content.

Abstract: A drive method for a display device that displays by causing charged particles to migrate by applying an electric field, including a gray level drive step of causing the particles to migrate to a gray level that is not a saturation state in which migration of the particles is saturated. The gray level drive step changes the display by causing the particles to migrate to produce a display color difference.

Abstract: A dial indicator display device according has a needle indicator; a needle moving means for moving the needle indicator; a display panel disposed behind the needle indicator and capable of displaying an image; and a drive control means for controlling the needle moving means and driving the display panel. The drive control means includes a scale display control means for displaying a scale in a scale display area on the display panel overlapping the range of needle movement in plan view, a needle position detection means for detecting the position of the needle indicator, and an information display means. The scale display control means segments the scale display area into a scale area and a no-scale area not including the scale area based on the needle position detected by the needle position detection means, and displays a scale for reading values indicated by the needle indicator only in the scale area, and the information display means displays information in the no-scale area.

Abstract: The clock signal output device has a crystal oscillator for generating a reference clock signal and generating and outputting an output clock signal having a prescribed frequency on the basis of the reference clock signal. The device also has an atomic oscillator for generating a clock signal having higher precision than a crystal oscillator, an intermittent time management unit for intermittently driving the atomic oscillator, and a correction unit for receiving correction data for correcting the offset amount of the output clock signal on the basis of a clock signal each time the atomic oscillator is driven, and correcting the output clock signal on the basis of the correction data.

Abstract: An electronic component comprising a display panel having an image retention characteristic, and a decorative member disposed layered to the display panel. The decorative member passes the display state of at least a portion of the display panel so that the display can be seen.

Abstract: A wristwatch having a display unit with memory that retains the display state of a last preceding display update operation, and a solar cell for displaying operating power at least to the display unit with memory during the display update operation. The display unit with memory and the solar cell render a dial or a display panel.

Abstract: There is provided a clock signal output device that can improve the precision of a clock signal while avoiding an increase in the overall power consumption even if a high-precision oscillator with relatively high power consumption is used, as well as a control method thereof, an electronic apparatus, and a control method thereof. The clock signal output device has a crystal oscillator (41) for generating a reference clock signal (CL1) and generating and outputting an output clock signal (CL0) having a prescribed frequency on the basis of the reference clock signal (CL1).
