摘要： A computer device, for instance a palmtop personal organizer, has a dual-orientation display device with both portrait and landscape modes of viewing the display. The keyboard is automatically disabled when the portrait mode is selected by a user. The display has two digitized regions separated by a workspace, which is preferably also digitized to provide input commands to a processor unit when touched. The display further includes indicia, such as icons or symbols shown on the display, which may be selected to activate a computer program, function or command. These icons are slanted and permanently fixed to the display, so they may be readily understood when viewed from either the portrait or landscape modes. A method is also provided of displaying indicia for viewing from two orthogonal directions. The invention further includes a way to use an analog touch-sensitive panel, having opposing resistive layers, to trigger an interrupt line used for returning the palmtop from a sleep mode. In addition, screen image rotation is accomplished by alternately configuring sets of LCD select lines either as column lines or row lines.

摘要： According to one or more embodiments, a variation is detected in light that is cast over a display interface of a computing device. A characteristic of the light variation is identified. From this characteristic, a determination is made as to whether the variation in light is to be interpreted as an input or to be ignored.

摘要： A mobile computing device comprises a power source, a display, a display driver and a control circuit. The power source is configured to provide a power signal. The display comprises a plurality of pixels. The display driver is configured to receive the power signal and to drive the pixels based on the power signal and display data. The control circuit is configured to periodically remove the power signal from at least a portion of the display driver.

摘要： A node to receive a first current and to couple a first or a second backlighting medium to the node. The first backlighting medium is to conduct the first current and the second backlighting medium to conduct a second current. A switch is coupled to the node and to the first or the second backlighting medium. The switch is to receive a control input signal and to conduct a third current if the second backlighting medium is coupled to the node.

摘要： A handheld computing device has a planar display and a superimposed, transparent digitizer. The combination is arranged to simulate writing or drawing with pencil on paper: the writing end of a passive stylus is pressed on and moved across the digitizer surface and a line on the display is produced directly under the stylus path. In order to complete the analogy to pencil and paper, display erasure is also provided. Under the display is located an inductive winding. The other end of the stylus contains a small permanent magnet. When the magnet end of the stylus is pressed against the digitizer and moved over a display line, a small voltage is induced in the inductive winding. This voltage is converted into a logic signal. The assertion of this signal together with a signal from the digitizer results in the erasure of display traces in the region inferred from the digitizer signal.
