Abstract

The present invention relates to a light path layout structure of a high-definition naked-eye portable stereoscopic video display and a light path circuit which enables the user to watch a stereoscopic video without wearing the stereoscopic glasses. Two video signals that are output from the stereoscopic video playing circuit board are synchronously displayed on a left liquid crystal display screen and a right liquid crystal display screen respectively. Sights from the left eye and the right eye of a person pass through a left eyepiece and a right eyepiece to a left eye reflector and a right eye reflector respectively. Images played on the left liquid crystal display screen and the right liquid crystal display screen are viewed via the left eye reflector and the right eye reflector respectively.
