Abstract
A display device including a display panel including a first substrate and a pixel array layer disposed on a first surface of the first substrate, a first sound generation device disposed on a second surface of the first substrate opposing the first surface, and configured to vibrate the display panel and output first sound, and a circuit board disposed on the second surface of the first substrate, in which the first sound generation device includes a bobbin fixed on one surface of the first substrate, a voice coil surrounding a side surface of the bobbin, a magnet disposed on the bobbin and spaced apart from the bobbin, and a plate disposed on the magnet and fixed to the circuit board.
Claims23
A display device comprising:
- a display panel including a first substrate and a pixel array layer disposed on a first surface of the first substrate;
- a first sound generation device disposed on a second surface of the first substrate opposing the first surface, and configured to vibrate the display panel and output first sound;
