Force dispersing device
One embodiment of the invention provides a force dispersing device for a display device. The display device has a casing, a backlight module and a display panel, the casing has a display opening, the backlight module is disposed in the display opening, and the display panel is disposed on the backlight module and in the display opening. The force dispersing device includes a fluid bag filled with a confined fluid and disposed between the casing and the backlight module.
1. A force dispersing device for a display device, the display device having a casing, a backlight module and a display panel, the casing having a display opening, the backlight module being disposed in the display opening, the display panel being disposed on the backlight module and in the display opening, and the force dispersing device comprising:
a fluid bag, filled with a confined fluid and disposed between the casing and the backlight module.
2. The force dispersing device as claimed in claim 1 , wherein the display device further comprises a keyboard, the keyboard has a raised portion, and the fluid bag overlaps the raised portion.
3. The force dispersing device as claimed in claim 1 , wherein the fluid bag has at least one separation structure to divide the fluid bag into multiple partitions.
4. The force dispersing device as claimed in claim 1 , wherein the fluid bag has at least one recess or hole.
5. The force dispersing device as claimed in claim 1 , wherein a gap between the casing and the backlight module has a thickness of smaller than 0.6 mm.
6. The force dispersing device as claimed in claim 1 , wherein the display device further comprises a frame, the frame is disposed on a periphery of the display opening, and the display panel and the backlight module are disposed on the frame.
7. A force dispersing device for dispersing a stress arisen from a stress concentration portion and imposed on at least one component inside a device, the force dispersing device comprising:
a confined fluid, pressing against the component to disperse the stress arisen from the stress concentration portion and imposed on the component, an area of the confined fluid being larger than a force exertion area on the component, and the stress concentration portion imposing the stress on the component via the force exertion area, wherein the stress concentration portion is a raised portion inside the device and the raised portion abuts against the component.
8. The force dispersing device as claimed in claim 7 , wherein the component has a first side and a second side opposite the first side, the stress concentration portion is on the first side, and the confined fluid presses against the component via the second side.
9. The force dispersing device as claimed in claim 7 , wherein the component is a display panel, and the confined fluid presses against the display panel via a backlight module interposed between the confined fluid and the display panel.
10. The force dispersing device as claimed in claim 7 , wherein the device is a display device, and the component is a casing, a frame, a backlight module or a display panel of the display device.
