Abstract
A transparent display device and an operational method therefor are disclosed. The transparent display device comprises: a memory; at least one sensor unit; and a control unit for adjusting the transmittance of a panel transmission module with respect to incident light on the basis of the average picture level (APL) value of and input image and the illuminance of the incident light calculated through the at least one sensor unit.
Claims16
A transparent display device, comprising:
- a memory;
- at least one sensor;
- and
- a controller configured to adjust a transmittance of a panel transmission module of an incident light based on an illuminance of the incident light calculated through the at least one sensor and an average picture level (APL) value of an input image at a same time.

A method for operating a transparent display device, comprising:
- determining whether it is a transparent mode;
- deactivating a control operation set in a light-blocking mode when it is the transparent mode;
- calculating an illuminance of an incident light and an average picture level (APL) value of an input image;
- and
- controlling a transmittance of a panel transmission module for the incident light based on, at a same time, at least two or more of the calculated illuminance of the incident light average picture level (APL) value of the input image, and the luminance value of a panel, depending on whether a brightness control algorithm is in operation.
