Abstract

Abstract : In order to solve the problem of the screen resolution degradation with the existing dual‐view technology, an improved solution is proposed and implemented Theoretical simulation and experimental results show that the display device have a wider viewport range and obtain better dual‐view display effect. It is worth mentioning that the resolution of the screen will not drop. The dual‐view display device is structured by LED backlight, light barrier, holographic diffuser and multi‐focus Fresnel lens.
