Abstract
A display device including: a display panel configured to display an image on a first surface thereof; a first sound generating device configured to provide a first sound; and a second sound generating device configured to provide a second sound, wherein the first sound generating device is attached to a second surface of the display panel, the second surface being opposite to the first surface, and wherein the first sound generating device is a vibration generating device configured to vibrate the display panel in accordance with a first sound signal to generate the first sound.
Claims20
A display device comprising:
- a display panel configured to display an image on a first surface thereof;
- a first sound generator attached to a second surface of the display panel to vibrate the display panel in accordance with a first sound signal to generate a first sound;
- a second sound generator attached to the second surface of the display panel to vibrate the display panel in accordance with a second sound signal for generating a second sound;
- a third sound generator configured to provide a third sound in accordance with a third sound signal;
- and
- a circuit board on which the third sound generator is disposed,
- wherein in a high frequency band, a sound pressure level of the first sound or a sound pressure level of the second sound is higher than a sound pressure level of the third sound,
- wherein in a low frequency band and a medium frequency band, the sound pressure level of the first sound or the sound pressure level of the second sound is lower than a sound pressure level of the third sound,
- wherein the medium frequency band is between the high frequency band and the low frequency band.
A display device comprising:
- a display panel configured to display an image on a first surface thereof;
- a panel bottom member configured to dissipate heat emitted by the display panel and being disposed on a second surface of the display panel, the second surface being opposite to the first surface;
- a first sound generator configured to provide a first sound;
- a second sound generator configured to provide a second sound;
- a display circuit board connected to the display panel;
- and
- a main circuit board electrically connected to the display circuit board, wherein:
- the first sound generator is attached to the panel bottom member;
- the second sound generator is disposed on the main circuit board;
- the first sound generator is a vibration generator configured to vibrate the display panel in response to a first sound signal;
- and
- the second sound generator is one of a speaker, an eccentric rotating mass, a linear resonant actuator, or a piezoelectric actuator.
A display device comprising:
- a display panel configured to display an image on a first surface thereof;
- a first sound generator attached to a second surface of the display panel to vibrate the display panel in accordance with a first sound signal to generate a first sound;
- a second sound generator attached to the second surface of the display panel to vibrate the display panel in accordance with a second sound signal for generating a second sound;
- a third sound generator configured to provide a third sound in accordance with a third sound signal;
- and
- a circuit board on which the third sound generator is disposed,
- wherein:
- each of the first sound generator and the second sound generator is a vibration generator configured to vibrate the display panel in response to a first sound signal;
- and
- a fundamental frequency of the first sound is higher than a fundamental frequency of the second sound.
