Autostereoscopic pixel emitting unit and 2D/3D auto-conversion display device

An autostereoscopic pixel emitting unit comprises a plurality of pixel units, a substrate, and an optical package structure. The specific chip is designed to emit light in a time-sequenced manner to the direction of right and left eyes of observer which is then combined in one's brain to provide the 3D perception. The autostereoscopic pixel emitting unit differentiates itself with prior arts by minimizing the size of the autostereoscopic display device to a component level. By using the autostereoscopic pixel emitting unit, a large-sized glasses-free 3D display maybe be assembled into a variety of configuration with the functions of 2D/3D auto-conversion and showing 2D and 3D contents in various area of the screen simultaneously. The present invention has multiple advantages such as free from panel optical lens, any large-sized screen area, flat or curved surface installation, cost-effective, and easy maintenance.
