A kind of privacy display solution is developed using dual cell stack up, which can achieved switchable function between share mode and privacy mode. First we build the lighting-field display model in theory by dual cell LCD device, then extract data require by dual image generate algorithm, so can get dual cell image by deep learning algorithm. Meanwhile we simulate to evaluate the privacy mode, and assemble the dual cell sample to verify the result. By calculating and comparing the difference between side view images and original image, the view angle can has obviously anti-peep effect if SSIM <0.2. The actual sample experiment is basically consistent with the above result. According to the experiment, can verify the dual cell image multiplication mode following the principle of lighting field theory. The view angle over 45° can get the chaos image and achieve privacy display condition.
