Abstract
A display apparatus and a method of driving the same for performing local dimming that is suitable for displaying a three-dimensional (3D) image. The display apparatus receives a video signal containing a left-eye image and a right-eye image, processes the video signal, displays a three-dimensional (3D) image on the basis of the processed video signal, emits light to a display unit by local dimming, and controls the light source unit to be driven based on dimming information about at least one of the left-eye image and the right-eye image.
Claims26
A display apparatus comprising:
- a signal receiver which receives a video signal, the video signal including a left-eye image and a right-eye image;
- a signal processor which processes the received video signal;
- a display unit which displays a three-dimensional (3D) image on the basis of the processed video signal;
- a light source unit which emits light to the display unit;
- and
- a controller which transmits dimming information of at least one of the left-eye image and the right-eye image of the processed video signal to the light source unit and controls the light source unit to be driven on the basis of the dimming information.
A method of driving a display apparatus comprising a plurality of light emitting diodes (LEDs), and a light source unit emitting light by local dimming, the method comprising:
- processing a video signal, the video signal including a left-eye image and a right-eye image;
- providing dimming information about at least one of the left-eye image and the right-eye image to the light source unit;
- driving the light source unit based on the dimming information;
- and
- displaying a three-dimensional (3D) image based on the driven light source unit.
