Abstract
An objective of the present disclosure is to adjust the degree of light-shielding of a transparent display according to a surrounding situation. A transparent display device according to an embodiment of the present disclosure includes a transparent display, a camera, and a controller configured to recognize a user located in front of the transparent display on the basis of an image captured through the camera and increase in transparency of the transparent display when an absence of the user is sensed during a first time after the recognition of the user.
Claims10
A transparent display device comprising:
- a transparent display;
- a camera;
- and
- a controller configured to:
- recognize a user located in front of the transparent display based on an image captured through the camera;
- increase transparency of the transparent display when an absence of the user is sensed during a first time after the recognition of the user;
- obtain direction information regarding a direction in which the transparent display device is placed, time zone information regarding a time zone, and season information;
- adjust the transparency of the transparent display based on one or more of the direction information, the time zone information, or the season information when a presence of the recognized user is continuously sensed after the recognition of the user;
- gradually decrease the transparency of the transparent display when a front surface of the transparent display faces north, and the time zone moves from morning to noon;
- and
- gradually increase the transparency of the transparent display when the front surface of the transparent display faces north, and the time zone moves from noon to afternoon.
A method for operating a transparent display device, the method comprising:
- recognizing a user located in front of a transparent display based on an image captured by a camera;
- increasing transparency of the transparent display when an absence of the user is sensed during a first time after the recognition of the user;
- obtaining direction information regarding a direction in which the transparent display device is placed, time zone information regarding a time zone, and season information;
- and
- adjusting the transparency of the transparent display based on one or more of the direction information, the time zone information, or the season information when a presence of the recognized user is continuously sensed after the recognition of the user,
- wherein adjusting the transparency of the transparent display comprises:
- gradually decreasing the transparency of the transparent display when a front surface of the transparent display faces north, and the time zone moves from morning to noon;
- and
- gradually increasing the transparency of the transparent display when the front surface of the transparent display faces north, and the time zone moves from noon to afternoon.
