ABSTRACT:
An arrangement for enhancing the observability of a multicolored liquid crystal display in a computer of the notebook type using an arrangement in which the top lid of the laptop is mechanically separated into a diffuser/reflective surface and the LCD in its frame, the diffusing/reflecting lid is attached through a slider and linkage arrangement permitting the diffuser/reflector to act as a flat field illuminator and to move in a plane, apart from, yet forming a dihedral angle with the plane of the LCD. The lid so positioned can opportunistically reflect ambient light through the plane of the LCD. Also, by causing the lid to project over the plane of the LCD, it secures a contrast-maintaining shadow otherwise bleached by light incident to the LCD viewing surface.
