Claims18
A display device, comprising:
- a display panel, including a substrate and a frame;
- a vibrator, disposed on the frame, wherein a portion of the frame is disposed between the substrate and the vibrator;
- an intermediary frame covering the vibrator and a surface of the display panel;
- an outer frame covering the intermediary frame;
- an adhesive layer, disposed between the frame and the vibrator, wherein a part of the adhesive layer contacts the frame, and another part of the adhesive layer contacts the vibrator, wherein the adhesive layer has an upper layer contacting a bottom of the frame, and a lower layer contacting a top of the vibrator, wherein the vibrator is connected with the frame by the adhesive layer, the vibrator vibrates the display panel to provide tactile feedback when the vibrator vibrates at a frequency larger than or equal to 1 Hz and smaller than or equal to 250 Hz, and the vibrator vibrates the display panel to provide acoustic function and generate sound capable of being concentrated inside the display panel when the vibrator vibrates at a frequency larger than or equal to 20 Hz and smaller than or equal to 20 KHz, and wherein the vibrator has a first thickness, the frame has a second thickness, and a ratio of the first thickness to the second thickness is between 50% to 70%;
- and
- a touch panel and a glass covering shield, wherein the display panel is disposed below the touch panel and the glass covering shield is disposed above the display panel and the touch panel.
