Abstract: A system for evaluating a quality of a transparent display, the system including: a background including any one of a full white pattern, a full black pattern, and a circle white pattern; a light detector positioned a first distance away from the background to measure luminance of the full white pattern, the full black pattern and the circle white pattern; and a circle transparent pattern displayed on the transparent display by passing light from at least one of the full white pattern, the full black pattern and the circle white pattern, further the transparent display is positioned between the background and the light detector and at a second distance away from the light detector, further a purity of the transparent display is calculated based on luminance of the full white pattern, the full black pattern, and the circle white pattern as measured by the light detector through the transparent display.
