In this paper, we propose an effective real-time image enhancing technology for transparent displays based on polymer-dispersed liquid crystal (PDLC). The image enhancing technology consists of both global and local enhancement functions. It not only removes the affected haze but also sharpens the edge regions for transparent PDLC displays. This technology can improve the image quality such as contrast, brightness, color saturation, and gamma correction for transparent PDLC displays. The experimental results indicated that our proposed method can effectively enhance the visibility and remove the affected haze in the transparent PDLC display.
