Abstract
The present disclosure relates to a transparent display having a variable light-shielding panel which may increase visibility by increasing ACR even in a bright room environment, and an image display device including same. The present disclosure may provide an image display device comprising: a transparent display including a transparent display panel and a variable light-shielding panel which overlaps one lateral surface of the transparent display panel; and a controller for performing control so that a portion of the variable light-shielding panel, which corresponds to a position of a video content being displayed in the transparent display panel, is in a light-shielding mode and the remaining portion is in a transparent mode.
Claims11
An image display device comprising:
- a transparent display comprising a transparent display panel and a variable shading panel overlaid on one side of the transparent display panel;
- and
- a controller configured to:
- control a portion of the variable shading panel related to a location of video content displayed on the transparent display panel to be in a shading mode;
- and
- control a remaining portion of the variable shading panel to be in a transparent mode,
- wherein the portion of the variable shading panel in the shading mode is determined by at least one of a plurality of image parameters of the video content, the at least one of the plurality of image parameters of the video content including at least one of contrast, brightness or sharpness of the video content, and
- wherein the portion of the variable shading panel in the shading mode is related to a region where the at least one of the plurality of image parameters of the video content is either greater than or equal to a predetermined value or smaller than the predetermined value.
A method of controlling an image display device, the method comprising:
- determining a display location of video content displayed on a transparent display panel;
- and
- controlling a portion of a variable shading panel overlaid on one side of the transparent display panel to be in a shading mode and a remaining portion of the variable shading panel to be in a transparent mode, wherein the portion of the variable shading panel is related to the display location,
- wherein the portion of the variable shading panel in the shading mode is determined by at least one of a plurality of image parameters of the video content, the at least one of the plurality of image parameters of the video content including at least one of contrast, brightness or sharpness of the video content, and
- wherein the portion of the variable shading panel in the shading mode is related to a region where the at least one of the plurality of image parameters of the video content is either greater than or equal to a predetermined value or smaller than the predetermined value.
