US 2015/0308951 A1 · SYSTEM FOR EVALUATING DISPLAYING QUALITY OF TRANSPARENT DISPLAY AND METHOD THEREOF

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.

A system for evaluating a quality of a transparent display, the system comprising:

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 and configured 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, wherein the transparent display is positioned between the background and the light detector and at a position with a second distance away from the light detector,
wherein a purity of the transparent display is calculated by the following equation 1:

A method for evaluating a quality of a transparent display, the method comprising:

positioning a background configured to represent any one of a full white pattern, a full black pattern, and a circle white pattern at a first distance away from a light detector;
aligning a center of the circle white pattern and a center of a receiving lens of the light detector onto an alignment axis;
positioning the transparent display between the background and the light detector and at a position with a second distance away from the light detector;
displaying a circle transparent pattern on a center of the transparent display;
aligning a center of the circle transparent pattern onto the alignment axis;
measuring a full white luminance of the full white pattern, a full black luminance of the full black pattern and a circle white luminance of the circle white pattern represented on the background, through the transparent display, with the light detector;
and
calculating a purity of the transparent display using the following equation 1:
