Abstract: A display apparatus, comprising a display having a longitudinal edge and a latitudinal edge, where the longitudinal edge is longer than the latitudinal edge, a first supporting member having an upper end portion rotatably coupled to the display and a lower end portion rotatably coupled to a base, wherein the display is configured to be rotatable between a first position in which the longitudinal edge is substantially in parallel with the base and a second position in which the longitudinal edge is substantially perpendicular to the base.

Abstract: A display mode switching device and method automatically switches a display mode of a television set to an overscan mode or to an underscan mode depending on a content of a screen. In a case of connecting a television set to a computer, a call from an application for an API in an OS is detected by a device driver when a user starts playing a DVD or a game. Accordingly, an output mode for the television set is switched to the overscan mode. In this way, a motion video or a game is displayed on the television set in the overscan mode. Meanwhile, when the user finishes playing the DVD or the game, a call for the API to release resources is detected by the device driver, and the output mode is restored to the underscan mode. In this way, a computer screen is displayed on the television set in the underscan mode.

Abstract: An information processor includes a power-saver which switches a display memory to a power-saving state that causes image data to be lost and restores the display memory from the power-saving state. A storage area stores a predetermined activation condition and an activation routine mechanism activates a predetermined routine when the activation condition is satisfied. A routine termination mechanism ends the routine and an image data re-creation mechanism executes re-creation of the image data on the display memory when the routine is terminated. Provided are: an activation condition rewriting mechanism which rewrites the activation condition stored in the storage area so that the routine is activated when the display memory is switched to or restored from the power-saving state; and an activation condition restoration mechanism which restores the rewritten activation condition to the original condition after the routine is activated.

Abstract: In order to conserve power in a computer display, an apparatus is provided to switch the display to a power-saving mode when, for example, no operation has been performed on the computer for some predetermined time. In the power-saving mode, a full-screen black screen is displayed behind any currently active window. Information about window location and activity is acquired and maintained to improve efficiency. Power-saving mode may be exited explicitly or in response to activity. Window order and display may also be switched on the fly appropriately.

Abstract: The refresh rate of an LCD panel is changed as the brightness of the LCD panel changes. When the brightness of the LCD panel is decreased, the refresh rate is also decreased. In addition, whether the power source of the apparatus is AC or DC is determined based on whether an AC adapter is attached or not. When the DC power source is used, the brightness and refresh rate of the LCD panel is lowered with respect to when the AC power source is used.

Abstract: A computer system, display device, display controller, and image processing method are described which provide high visibility and usability. A portion of an image displayed on a display screen of the display device is enlarged in one direction and the enlarged image is displayed in a window. In one example, a portion of the image displayed in the display is enlarged in the vertical direction when the text runs along a horizontal direction.

Abstract: Disclosed are a display control unit and a control method therefor, for permitting images provided by a plurality of video image sources to overlie, whereby an area of an overlying image plane wherein an original video image source that is composed of lines and shade patterns is displayed by interpolating an original image, and whereby an area wherein an original video image source that is composed of video images is displayed non-interpolated without interpolation. According to the present invention, whether or not the interpolation on image data is required is determined for each pixel by employing a changed value of luminance for each pixel between scan lines, a color difference signal, and color data. Even when a computer image and a video image are displayed on the same screen at the same time, optimal display can be performed on the individual image planes.
