ABSTRACT:
An improved portable notebook computer having a base (15) connected to a display unit (20) that folds along a spine (26). The display unit (20) is pivotally coupled to the base (15) for motion and houses a plurality of display components including a light source (85), light guide (80) and LCD (50). The display drive circuits (115), light source (85), power board (165) and related display components are relocated to the base (15) reducing the thickness and weight of the display unit (20). PWB's (115, 120, 125) used to control LCD (50) display functions are maintained on the display case back (70) to take advantage of available space within the display unit (20). A flexible circuit (330) extends from the base (15) to the display unit (20) to connect the display drive circuits (115) to the PCB's (115, 120, 125) for controlling LCD (50) display functions.
