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.

System for evaluating displaying quality of transparent display and method thereof

A data correcting method is disclosed to implement an optimum picture quality according to surrounding conditions. The data correcting method includes: converting the input data into XYZ color space data; converting the XYZ color space data into JCh color space data by applying a reference illuminance parameter to a CIECAM02 forward algorithm; inversely converting the JCh color space data into the XYZ color space data by the illuminance by sequentially applying a plurality of illuminance parameters different from the reference illuminance, to a CIECAM02 backward algorithm; inversely converting the inversely converted XYZ color space data into an RGB color space to produce correction data of each illuminance; and making a look-up table by mapping the produced correction data of each illuminance to the input data.
