Abstract
Provided are display devices and methods of driving the same. A display device may include: a display panel, a main sound generator and a sub-sound generator disposed on a surface of the display panel. The main sound generator outputs sound in a first directional mode, and each of the main sound generator and the sub-sound generator outputs sound in a second directional mode. Each directional mode may be a mode in which sound is directed towards a particular viewer's location.
Claims31
A display device comprising:
- a display panel;
- and
- a main sound generator, a first sub-sound generator, and a second sub-sound generator, each disposed on a surface of the display panel,
- wherein the main sound generator outputs sound in a first mode, the main sound generator and the first sub-sound generator output sound in a second mode, the main sound generator and the second sub-sound generator output sound in a third mode, and the main sound generator is disposed closer to a center of the display panel than the first sub-sound generator and the second sub-sound generator.

A method of driving a display device, the method comprising:
- capturing an image of an area in front of a display device using a camera sensor;
- and
- executing, by processing circuitry, operations comprising:
- determining the position of a user by analyzing the image captured by the camera sensor;
- controlling a main sound generator disposed within a central region of the display device to output sound when the user is located opposing the central region of the display device;
- controlling each of a first sub-sound generator, which is disposed closer to a first side of the display device than the main sound generator, and the main sound generator to output sound when the user is located opposing the first side of the display device;
- and
- controlling the main sound generator and a second sub-sound generator, which is disposed closer to a second side of the display device than the main sound generator, to output sound when the user is located opposing the second side of the display device.
5 more elements
A display device comprising:
- a display panel;
- and
- plural sound generators, laterally spaced from one another across a rear surface of the display panel and each vibrationally coupled to the rear surface of the display panel;
- and
- processing circuitry configured to activate selected ones of the sound generators to produce:
- (i) in a first mode, first sound that reaches a first location at a sound level higher than that reaching a second location;
- and (ii) in a second mode, second sound that reaches the second location at a higher sound level than that reaching the first location.
