Abstract
Provided is a display apparatus including a substrate, a plurality of light emitting devices arranged in a two-dimensional (2D) matrix on the substrate, a power supply comprising a plurality of power lines configured to provide power to the plurality of light emitting devices, and a controller configured to control the power supply to turn on and off each power line of the plurality of power lines a plurality of times in one frame.
Claims17
A display apparatus comprising:
- a substrate;
- a plurality of light emitting devices arranged in a two-dimensional (2D) matrix on the substrate;
- a power supply comprising a plurality of power lines configured to provide power to the plurality of light emitting devices;
- and
- a controller configured to:
- control the power supply to turn on power to each power line at least four times in one frame, and turn off power to each power line of the plurality of power lines at least four times in the one frame, wherein a total time in which power is turned on to each power line across an entirety of the one frame is less than a total time in which the power is turned off to each power line across the entirety of the one frame.
A method of controlling a display apparatus including a substrate, a plurality of light emitting devices arranged in a two-dimensional (2D) matrix on the substrate, and a power supply comprising a plurality of power lines configured to provide power to the plurality of light emitting devices, the method comprising:
- controlling the power supply to turn on power to the plurality of power lines at different times;
- and
- controlling the power supply to turn on power to each power line at least four times in one frame, and turn off power to each power line of the plurality of power lines at least four times in the one frame, wherein a total time in which power is turned on to each power line across an entirety of the one frame is less than a total time in which the power is turned off to each power line across the entirety of the one frame.
A display apparatus comprising:
- a plurality of light emitting devices;
- a power supply comprising a plurality of power lines configured to provide power to the plurality of light emitting devices;
- and
- a controller configured to:
- control the power supply to turn on power to each power line at least four times in one frame, and turn off power to each power line of the plurality of power lines at least four times in the one frame, wherein a total time in which power is turned on to each power line across an entirety of the one frame is less than a total time in which the power is turned off to each power line across the entirety of the one frame;
- and
- control the power supply to turn on power to each power line of the plurality of power lines for a same period of time.
