Low-color-difference transparent display device

The invention provides a low-chromatic-aberration transparent display device in order to solve the problem that chromatic aberration easily occurs in polarization modulation stereoscopic display adopting a 1 / 4 wave plate. The low-color-difference transparent display device comprises a directional polarization light source, a reflector and a transparent liquid crystal display panel. The pixels on the upper portion of the 2D display panel are lightened in a time-division multiplexing mode and any time slice slot, light rays of the pixels are projected through the lens array and then reflected through the reflector, the polarization direction of the light rays is adjusted, and then the light rays penetrate through the transparent liquid crystal display panel to form viewpoints. The transparent liquid crystal display panel synchronously provides a parallax image corresponding to the viewpoint position. The sub-pixel value of any one lightened pixel on the 2D display panel is modulated to be a fixed value related to the included angle of the lens, so that colored light generated by the pixel is restored to be white light after being polarized by the polarizer, the polarization direction is adjusted by the 1 / 4 wave plate and the polarization of the analyzer. At the moment, a directional light source without chromatic aberration is provided for the transparent liquid crystal display panel, so that chromatic aberration introduced by the polaroid and the wave plate is reduced.
