Abstract
A display apparatus includes a display including a plurality of display modules, a display driver including a plurality of driving modules respectively connected to the plurality of display modules, a storage storing current information concerning a plurality of display modules, and a processor calculating a peak luminance level of each of a plurality of display modules based on individual power consumptions of each of a plurality of display modules and controlling a plurality of driving modules using the current information stored in the storage based on the calculated peak luminance level.
Claims19
A display apparatus, comprising:
- a display comprising a plurality of display modules, the plurality of display modules comprising;
- one or more display drivers;
- and
- a processor configured to:
- identify a power consumption corresponding to each of the plurality of display modules;
- identify a maximum power consumption from among a plurality of power consumptions respectively corresponding to each of the plurality of display modules;
- identify a reference display module consuming the maximum power consumption;
- identify a power increase rate by dividing a maximum power amount of the reference display module by the power consumption of the reference display module;
- identify current information corresponding to each of the plurality of display modules based on the power increase rate and luminance information of an input image;
- and
- control the one or more display drivers to control an input current to each of the plurality of display modules based on the identified current information for each of the plurality of display modules,
- wherein each of the plurality of display modules comprises light emitting diode (LED) pixels, and
- wherein the current information comprises current control information according to luminance of each of the LED pixels of the plurality of display modules.
A method for controlling a display apparatus including a display comprising a plurality of display modules and one or more display drivers, the method comprising:
- identifying a plurality of power consumptions respectively corresponding to the plurality of display modules;
- identifying a maximum power consumption from among the plurality of power consumptions respectively corresponding to each of the plurality of display modules;
- identifying a reference display module consuming the maximum power consumption;
- identifying current information corresponding to each of the plurality of display modules based on the maximum power consumption of the reference display module and luminance information of an input image;
- and
- controlling an input current to each of the plurality of display modules based on the identified current information for each of the plurality of display modules,
- wherein each of the plurality of display modules comprises light emitting diode (LED) pixels, and
- wherein the current information comprises current control information according to luminance of each of the LED pixels of the plurality of display modules.
