20110175861 | DISPLAY DEVICE - To reduce power consumption of a display device with the use of a simple structure and a simple operation. The display device includes an input device. Input of an image signal to a driver circuit is controlled in accordance with an image operation signal output from the input device. Specifically, input of image signals at the time when the input device is not operated is less frequent than that at the time when the input device is operated. Accordingly, display degradation (deterioration of display quality) caused when the display device is used can be prevented and power consumed when the display device is not used can be reduced. | 07-21-2011 |
20110175874 | Display Device And Method For Driving The Same - A liquid crystal display device includes an optical sensor provided near an end portion of a liquid crystal display panel, a pixel provided in a display region of the liquid crystal panel, and a monitoring pixel. The optical sensor detects illuminance of light delivered from the liquid crystal display panel side. The pixel for which a transistor whose off-state current is low and the monitoring pixel are supplied with a potential to display a still image, at least light transmitted through a liquid crystal layer of the monitoring pixel is detected by the optical sensor, and the pixel in the display region of the liquid crystal display panel and the monitoring pixel are supplied again with a potential when a rate of change in illuminance reaches a predetermined value, so that the still image is kept being displayed. | 07-21-2011 |
20110175894 | METHOD FOR DRIVING DISPLAY DEVICE - An object is to provide a convenient display device which consumes sufficiently small amount of power and a method for driving such a display device. The display device can be in an off state with a still image displayed in a still image display mode in which a pixel electrode and a common electrode which are for applying a voltage to the display element are brought into a floating state so that a voltage applied to the display element is held, and a still image is displayed without further supply of a potential. The display device is put to an off state with a desired image displayed in the still image display mode, whereby the display device can have a higher level of security and can be more convenient. | 07-21-2011 |
20110175895 | METHOD FOR DRIVING DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE - The still image display mode includes a first period of writing the data of the image signal from the driver circuit portion into the pixel; after the first period, a second period of stopping supply of a signal or voltage for operating the driver circuit portion to the driver circuit portion; and after the second period, a third period of restarting the supply of a signal or voltage for operating the driver circuit portion to the driver circuit portion and writing the data of the image signal into the pixel from the driver circuit portion, so that the pixel keeps displaying a still image. A length of a period from the stop of the supply of the signal for operating the driver circuit portion to the driver circuit portion to the restart is set in accordance with a temperature of the display device. | 07-21-2011 |
20110181802 | DISPLAY METHOD OF DISPLAY DEVICE - A display method suitable for an image provided by a digital data file and/or a display method of a display device in which the image quality and power consumption are adjusted in accordance with the state of the display device or at user's request to display an image. The image is displayed on the display device in which a plurality of pixels having a pixel electrode connected to a switching element whose off-state current is reduced, using the image provided by the digital data file and data which is provided by the digital data file and is correlated to an operation of the display device. | 07-28-2011 |
20110241558 | Light-Emitting Device and Driving Method Thereof - It is an object to provide a light-emitting device whose light is not entirely turned off owing to disconnection (an insulation defect) in part of light-emitting elements and the whole of which can be driven by one constant current supply without causing variation in brightness. Further, it is an object to provide a light-emitting device in which brightness can be adjusted. In addition, it is an object to provide a light-emitting device in which change in properties of light-emitting elements over time due to the use thereof is less likely to appear as variation in brightness. In order to achieve the above object, a light-emitting device in which a plurality of light-emitting panels are connected to a constant current supply controlled by a light-emission control unit may be used, and each of the light-emitting panels may be sequentially driven, independently. The plurality of light-emitting panels provided in the light-emitting device may be used evenly so that difference in total operating time is not caused among them. | 10-06-2011 |
20110279992 | Electronic Apparatus and Method for Connecting Electronic Device - Electronic devices which are selected by a user are coupled together through a coupler to provide a portable electronic apparatus. At least one of the electronic devices is provided with a pair of first connection terminal groups whose polarities are symmetric with respect to one rotation axis. The coupler is provided with a second connection terminal group. In addition, since the electronic device is detachable from the spindle through the coupler, the electronic device can be coupled to the coupler after the electronic device is reversed by the rotation about one rotation axis. A plurality of electronic devices can be connected to each other through the first connection terminal group and the second connection terminal group of the coupler. | 11-17-2011 |
