ABSTRACT:
The present invention relates to a sunlight readable computing device, especially, to a full color direct-view and projection-view computing device. When the computing device works in the direct-view mode, the display panel tilt up to the conventional display position and it has a wide, open viewing angle; when the computing device works in the projection view mode, the display panel tilt down and forms a projection image via a mirror plate with a sufficient high contrast ratio and superior readability even directly under sunshine. The solar ambient light can be utilized as the lighting source in both direct-view and projection-view display modes, thus remarkably reduces the power consumption and substantially prolongs the operation time of the computing device.
