Abstract
A display device includes: a net power control circuit configured to analyze a screen load from an input image signal to generate a load signal including a load value corresponding to the screen load; and an overcurrent protection circuit configured to set a set current value at a predetermined ratio with respect to a global current value corresponding to the load value included in the load signal, and to determine whether or not the display device is powered off based on the set current value.
Claims20
A display device comprising:
- a net power control circuit configured to analyze a screen load from an input image signal to generate a load signal including a load value corresponding to the screen load;
- and
- an overcurrent protection circuit configured to set a set current value at a predetermined ratio with respect to a global current value corresponding to the load value included in the load signal, and to determine whether or not the display device is powered off based on the set current value.
A driving method of a display device, comprising:
- analyzing a screen load from an input image signal;
- selecting a load value corresponding to the screen load;
- selecting a global current value corresponding to the selected load value;
- and
- setting a set current value of an overcurrent protection circuit corresponding to the selected load value,
- wherein whether the display device is powered off is determined based on the set current value.
