Abstract

A portable electronic device includes a casing, a flexible display panel, a cushion, an inflatable pad, a gas transportation device and a sensing unit. The flexible display panel is embedded in the casing and including a movable region. The cushion is attached on a bottom surface of the movable region. The inflatable pad is attached on a bottom surface of the flexible display panel and covers the cushion. The gas transportation device is in communication with the inflatable pad and electrically connected with the sensing unit. When the sensing unit is touched by a user, a first driving signal is transmitted from the sensing unit to the gas transportation device, in response to which the gas transportation device inflates the inflatable pad again to raise the cushion, so that the movable region corresponding to the cushion is raised.

First claim

What is claimed is:

1. A portable electronic device, comprising:
a casing;
a flexible display panel coupled with the casing and comprising a movable region;
a cushion attached on the movable region of the flexible display panel;
an inflatable pad attached on a bottom surface of the flexible display panel and covering the cushion;
a gas transportation device disposed within the casing and in communication with the inflatable pad to transfer gas to the inflatable pad so that the inflatable pad is inflated and supporting the flexible display panel; and
a sensing unit electrically connected with the gas transportation device, wherein when an external contact force is sensed by the sensing unit, the sensing unit transmits a first driving signal to the gas transportation device, wherein in response to the first driving signal, the gas transportation device transfers gas to the inflatable pad to expand the inflatable pad and make the inflatable pad raise the cushion, so that the movable region of the flexible display panel corresponding to the cushion is raised.

2. The portable electronic device according to claim 1 , wherein the flexible display panel comprises a sensing layer and a displaying layer, wherein the displaying layer is located over the sensing layer.

3. The portable electronic device according to claim 2 , wherein the flexible display panel further comprises a covering layer located over the displaying layer.

4. The portable electronic device according to claim 1 , wherein a key is embedded in a lateral side of the portable electronic device, and a gas bag is located under the key and in communication with the gas transportation device, wherein when the external contact force is sensed by the sensing unit, a second driving signal is transmitted from the sensing unit to the gas transportation device, wherein in response to the second driving signal, the gas transportation device transfers gas to the gas bag to expand the gas bag, so that the key is raised by the gas bag.

5. The portable electronic device according to claim 4 , wherein the portable electronic device further comprises at least one communication pipe, wherein the at least one communication pipe is in communication between the gas transportation device and the inflatable pad or in communication between the gas transportation device and the gas bag.

6. The portable electronic device according to claim 1 , wherein the gas transportation device comprises:
a gas inlet plate;
a resonance plate having a central aperture;
a piezoelectric actuator; and
a gas collecting plate comprising a recess, a fiducial surface and a perforation, wherein the piezoelectric actuator, the resonance plate and the gas inlet plate are stacked on each other sequentially and accommodated within the recess, wherein a gas-collecting chamber is concavely formed on a bottom surface of the recess, the gas-collecting chamber is in communication with the perforation, and the piezoelectric actuator is located over the gas-collecting chamber to seal the gas-collecting chamber,
wherein a temporary storage chamber is formed between the resonance plate and the piezoelectric actuator, wherein when the piezoelectric actuator is actuated, the gas is sequentially fed into the gas inlet plate, transferred through the resonance plate, introduced into the temporary storage chamber, transferred to the gas-collecting chamber, and discharged from the gas collecting plate through the perforation, so that the gas is continuously transferred by the gas transportation device.

7. A portable electronic device, comprising:
a casing;
a display panel coupled with the casing and comprising a pliable display region;
a cushion attached on the pliable display region of the display panel;
an inflatable pad attached on a bottom surface of the display panel and covering the cushion;
a gas transportation device disposed within the casing and in communication with the inflatable pad to transfer gas to the inflatable pad so that the inflatable pad is inflated and supporting the display panel; and
a sensing unit electrically connected with the gas transportation device, wherein when an external contact force is sensed by the sensing unit, the sensing element transmits a first driving signal to the gas transportation device, wherein in response to the first driving signal, the gas transportation device transfers gas to the inflatable pad to expand the inflatable pad and make the inflatable pad raise the cushion, so that the pliable display region of the display panel corresponding to the cushion is raised.

8. The portable electronic device according to claim 7 , wherein the display panel comprises a sensing layer and a displaying layer, wherein the displaying layer is located over the sensing layer.

9. The portable electronic device according to claim 8 , wherein the display panel further comprises a covering layer located over the displaying layer.

10. The portable electronic device according to claim 7 , wherein a key is embedded in a lateral side of the portable electronic device, and a gas bag is located under the key and in communication with the gas transportation device, wherein when the external contact force is sensed by the sensing unit, a second driving signal is transmitted from the sensing unit to the gas transportation device, wherein in response to the second driving signal, the gas transportation device transfers gas to the gas bag to expand the gas bag, so that the key is raised by the gas bag.

11. The portable electronic device according to claim 7 , wherein the gas transportation device comprises:
a gas inlet plate;
a resonance plate having a central aperture;
a piezoelectric actuator; and
a gas collecting plate comprising a recess, a fiducial surface and a perforation, wherein the piezoelectric actuator, the resonance plate and the gas inlet plate are stacked on each other sequentially and accommodated within the recess, wherein a gas-collecting chamber is concavely formed on a bottom surface of the recess, the gas-collecting chamber is in communication with the perforation, and the piezoelectric actuator is located over the gas-collecting chamber to seal the gas-collecting chamber,
wherein a temporary storage chamber is formed between the resonance plate and the piezoelectric actuator, wherein when the piezoelectric actuator is actuated, the gas is sequentially fed into the gas inlet plate, transferred through the resonance plate, introduced into the temporary storage chamber, transferred to the gas-collecting chamber, and discharged from the gas collecting plate through the perforation, so that the gas is continuously transferred by the gas transportation device.
