Abstract
Disclosed are a display device and a method for operating the same. The display device includes a memory, a display, and a processor configured to set a first video output clock frequency for an input signal and output a video based on the set first video output clock frequency, wherein the processor is configured to set at least one second video output clock frequency, calculate an optimal video output clock frequency based on device performance information according to each set video output clock frequency and set the calculated optimal video output clock frequency as a video output clock frequency for the input signal.
Claims12
A display device comprising:
- a memory;
- a display;
- and
- a processor configured to set a first video output clock frequency for an input signal and output a video included in the input signal,
- wherein the processor is configured to;
- set at least one second video output clock frequency in a background while simultaneously outputting the video based on the first video output clock frequency
- and determine one of the at least one second video output clock frequency as an optimal video output clock frequency based on a calculated device performance information including image quality data of an output video and data on a change in chip temperature and power consumption according to each of the at least one second video output clock frequency, and
- set the determined optimal video output clock frequency as a video output clock frequency for the input signal,
- wherein calculating the device performance information includes:
- setting priorities for image quality data of the output video and data on the change in chip temperature and power consumption and assigning weights according to the set priorities;
- and
- summing the weights of the image quality data and the data on the change in chip temperature and power consumption according to the at least one second video output clock frequency.
A method for operating a display device, comprising:
- detecting a change in resolution according to an input signal;
- setting a first video output clock frequency according to a changed resolution and outputting a video based on the set first video output clock frequency;
- setting at least one second video output clock frequency in a background while simultaneously outputting the video based on the first video output clock frequency;
- determining one of the at least one second video output clock frequency as an optimal video output clock frequency based on a calculated device performance information including image quality data of an output video and data on a change in chip temperature and power consumption according to each of the at least one second video output clock frequency;
- and
- setting the determined optimal video output clock frequency as a video output clock frequency for the input signal,
- wherein calculating the device performance information includes:
- setting priorities for image quality data of the output video and data on the change in chip temperature and power consumption and assigning weights according to the set priorities;
- and
- summing the weights of the image quality data and the data on the change in chip temperature and power consumption according to the at least one second video output clock frequency.
