    摘要: A portable computer system (e.g., a palmtop or hand-held computer system) with a universal interface module containing circuitry needed to connect with and operate a device such as a display device. The interface module is coupled between the display device and a printed circuit board (e.g., a central processing unit). The interface module can be coupled to the display device using a flexible circuit. In that case, the interface module is pivotable about the flexible circuit so that it can be positioned in different locations within the computer system, depending on space availability and the constraints of a particular computer system design. Thus, the combination of the interface module, the device, and/or the flexible circuit and can be universally implemented in different designs of portable computer systems, reducing development time and manufacturing costs.

    摘要: A method and system for enhancing the life of a battery within a portable or otherwise battery operated electronic device. The method and system provide user selectable display modes, e.g., from color to monochrome, that can be changed in order to enhance the life of the device's battery. The monochrome display mode can be selected by the user when the battery level is detected below a predefined threshold. In one embodiment, the electronic device is a hand held computer system with a display device. When the battery level is detected as below a preselected level, a message is generated on the computer display screen. The message informs the user that the display mode of the screen can be changed to enhance the battery life. If selected, the display mode can change from color to monochrome thereby saving power because the monochrome display does not utilize a back-lighting element. In one embodiment, color sequential techniques are used to provide a flat panel color display. Within the display, a transreflective layer provides reflective light for monochrome applications. When the battery energy returns to normal levels, the color display mode can be re-entered automatically. It is appreciated that the display mode changes can also be performed automatically if the battery level falls below certain critical levels.
