Abstract: The present invention relates to an apparatus for supplying power source for providing power source to a plurality of display devices. The apparatus for supplying power source includes a boosting circuit and a voltage adjusting circuit. The boosting circuit boosts a battery voltage to a first voltage, and supplies the first voltage to a first display device. The voltage adjusting circuit adjusts the first voltage to a second voltage, and supplies the second voltage to a second display device. The apparatus supplies a voltage outputted from a boosting circuit to a first display device, downs the voltage through a voltage adjusting circuit, and then supplies the downed voltage to a second display device. In other words, the apparatus of the present invention may provide voltages having different magnitude to a plurality of display devices, respectively.
Abstract: Detailed herein is a technology which, among other things, provides a touch screen interface for computer system which allows intuitive switching between several applications. In one approach to this technology, a touch screen display is used to display an interface for an application. A touch sensitive border region is defined at the edge of this display, and is associated with another application. Receiving input at the touch sensitive border region causes the touch screen display to display the interface for the second application.

Abstract: An image display device and a method of controlling an image display device are provided. The image display device may include a signal processor having a plurality of input/output ports to control a degaussing operation and a data download, a degaussing circuit connected a first port of the signal processor to perform the degaussing operation during a first mode, and a download interface connected to the first port of the signal processor to download data on the signal processor during a second mode.
Abstract: According to one embodiment, an information processing apparatus includes a display unit. A display portion is provided in the display unit. An antenna is provided in the display unit and radiates radio waves. When the display unit is used in a usage pattern where the antenna is located in a side of the display unit which side is closest to a user, a controlling unit controls a direction of an image displayed on the display portion not to correspond to a direction of the display unit.
Abstract: A liquid crystal display is provided, which includes: a plurality of pixels; a gray voltage generator generating a plurality of gray voltages; an image signal modifier that receives first, second, and third image signals for a pixel in three successive frames, generates a preliminary signal for the second image signal based on the first image signal, and generates a modified signal for the second image signal based on the preliminary signal and the third image signal; and a data driver converting the modified signal into a data voltage selected from the gray voltages and applying the data voltage to the pixel, wherein a range of the gray voltages is substantially equal to a range of target voltages for obtaining target luminance of the pixel, and a highest available value for the modified signal is equal to a highest available value of the image signals.
Abstract: A circuit and method for controlling a micro-electromechanical system is herein disclosed. In one embodiment of a micro-electromechanical system having top and bottom capacitor plates with a pixel plate movably positioned therebetween, a release voltage sufficient to overcome stiction forces adhering the pixel plate to one of the capacitor plates is applied to the pixel plate to cause the pixel plate to be attracted to the pixel plate opposite the capacitor plate to with which the pixel plate is in contact. After the pixel plate has moved a predetermined distance away from the capacitor plate to which it had been adhered by stiction forces, the release voltage is removed. Thereafter, an positional voltage is applied to the pixel plate to move the pixel plate to a desired location between the capacitor plates. Release and positional voltages are coupled to and decoupled from the pixel plate by one or more switching mechanisms.

Abstract: A voltage supply circuit which switches a first voltage supplied to an electrode to a second voltage and supplies the second voltage to the electrode including: a first voltage boost circuit including a switching element for generating a boosted voltage boosted by charge-pump operation; and a charge supply circuit for supplying a charge to the electrode. When the first voltage is switched to the second voltage, the charge supply circuit supplies a charge to the electrode so as to maintain the voltage of the electrode at the second voltage after the boosted voltage has been supplied to the electrode.
Abstract: The present invention relates to an organic electroluminescent device and driving method thereof. The method of driving an electroluminescent device having a plurality of pixels formed on emitting areas crossed by data lines and scan lines comprises detecting a gray scale of a data current according to a display data inputted from outside, and discharging the data lines to a discharging level corresponding to the display data according to the detected gray scale. The organic electroluminescent device and driving method thereof according to the present invention can emit the pixels as desired brightness independently of a gray scale by making the discharging circuit regulate the discharge level according to the gray scale.
Abstract: A plasma display apparatus and driving method thereof are disclosed. The plasma display apparatus comprises: a plasma display panel comprising scan electrodes and sustain electrodes, a scan driver for supplying a first pulse to the scan electrodes before a reset period of a first subfield, a first reset pulse gradually falling after maintaining a constant voltage to the scan electrodes during the reset period, and a second reset pulse having a voltage higher than the constant voltage of the first reset pulse to the scan electrodes during a reset period of a second subfield and a sustain driver for supplying a second pulse with a polarity opposite a polarity of the first pulse to the sustain electrodes corresponding to the first pulse before the reset period.
