Abstract
Provided are a display device and an operating method thereof. The display device includes a wireless communication interface configured to receive image data from an external device, a display configured to output a screen of the external device by using the image data, and a controller configured to operate in a delay off mode or a delay on mode to minimize a delay of screen output while outputting the screen of the external device.
Claims17
A display device comprising:
- a wireless communication interface configured to receive image data from an external device;
- a display configured to output a screen of the external device by using the image data;
- and
- a controller configured to while outputting the screen of the external device, operate in a delay on mode or a delay off mode that minimizes a delay of screen output,
- wherein the controller is further configured to control a screen output speed of the external device, while switching from the delay off mode to the delay on mode, to be slower than a screen output speed of the external device in the delay on mode,
- wherein the controller is further configured to operate in the delay off mode or the delay on mode according to whether a user input back channel (UIBC) is activated, the UIBC being able to control the external device through a pointer.
