Abstract

A flexible display device includes a flexible display panel including a first side and a second side, wherein the first side is opposite to the second side; a roll-up mechanism including a master shaft for rolling up and unrolling the flexible display panel, wherein the first side of the flexible display panel is fixed to the master shaft; a support mechanism including a plurality of supporting members, wherein the supporting members are articulated each other; wherein the supporting members are stored under the flexible display panel, when the flexible display panel is rolled up; wherein the supporting members are leaned to a backside surface of the flexible display panel, when the flexible display panel is unrolled.

Claims (42)

1. A flexible display device comprising:

a flexible display panel comprising a first side and a second side, wherein the first side is opposite to the second side;

a roll-up mechanism comprising a master shaft for rolling up and unrolling the flexible display panel, wherein the first side of the flexible display panel is fixed to the master shaft;

a support mechanism comprising a plurality of supporting members, wherein the supporting members are articulated each other;

a housing for receiving the roll-up mechanism;

wherein the supporting members are stored under the flexible display panel, when the flexible display panel is rolled up;

wherein the supporting members are leaned to a backside surface of the flexible display panel, when the flexible display panel is unrolled;

wherein a surface of the support mechanism comprises a guiding groove, and a bottom of the housing is sliding inlaid in the guiding groove, wherein the flexible display panel is rolling up and unrolling in response to sliding movements, in the guiding groove, of the housing.

2. The flexible display device of claim 1 , wherein a side wall of the housing comprises an opening which allows the flexible display panel to pass through, and the roll-up mechanism further comprises:

a slave shaft, disposed on a side of the opening to guide the flexible display panel between the slave shaft and the support mechanism when rolling up and unrolling the flexible display panel.

3. A flexible display device, comprising:

a flexible display panel comprising a first side and a second side, wherein the first side is opposite to the second side;

a roll-up mechanism comprising a master shaft for rolling up and unrolling the flexible display panel, wherein the first side of the flexible display panel is fixed to the master shaft;

a support mechanism comprising a plurality of supporting members, wherein the supporting members are articulated each other;

wherein the supporting members are stored under the flexible display panel, when the flexible display panel is rolled up;

wherein the supporting members are leaned to a backside surface of the flexible display panel, when the flexible display panel is unrolled;

wherein a surface of the support mechanism comprises a guiding groove, and a guiding wheel is disposed at the second side of the flexible display panel, the guiding wheel is sliding inlaid in the guiding groove;

wherein the flexible display panel is rolling up and unrolling in response to sliding movements, in the guiding groove, of the guiding wheel.

4. The flexible display device of claim 3 , further comprising a housing for receiving the roll-up mechanism and the support mechanism, wherein a side wall of the housing comprises an opening which allows the flexible display panel and the support mechanism to pass through;

wherein the roll-up mechanism further comprises a slave shaft, disposed on a side of the opening to guide the flexible display panel between the slave shaft and the support mechanism when rolling up and unrolling the flexible display panel.

5. The flexible display device of claim 1 , wherein a surface of the support mechanism comprises adsorbing micro-pores.

6. A mobile terminal comprising a flexible display device, wherein the flexible display device comprises:

a flexible display panel comprising a first side and a second side, wherein the first side is opposite to the second side;

a roll-up mechanism comprising a master shaft for rolling up and unrolling the flexible display panel, wherein the first side of the flexible display panel is fixed to the master shaft;

a support mechanism comprising a plurality of supporting members, wherein the supporting members are articulated each other,

a housing for receiving the roll-up mechanism;

wherein the supporting members are stored under the flexible display panel, when the flexible display panel is rolled up;

wherein the supporting members are leaned to a backside surface of the flexible display panel, when the flexible display panel is unrolled;

wherein a surface of the support mechanism comprises a guiding groove, and a bottom of the housing is sliding inlaid in the guiding groove, wherein the flexible display panel is rolling up and unrolling in response to sliding movements, in the guiding groove, of the housing.

7. The flexible display device of claim 1 , wherein the support mechanism comprises a first supporting member and a second supporting member;

when the flexible display device is in the storage state, the second supporting member is stacked with the first supporting member.

8. The flexible display device of claim 3 , wherein the support mechanism comprises a first supporting member and a second supporting member;

when the flexible display device is in the storage state, the second supporting member is stacked with the first supporting member.

9. The flexible display device of claim 3 , wherein a surface of the support mechanism comprises adsorbing micro pores.

10. A mobile terminal comprising a flexible display device, wherein the flexible display device comprises:

a flexible display panel comprising a first side and a second side, wherein the first side is opposite to the second side;

a roll-up mechanism comprising a master shaft tor rolling up and unrolling the flexible display panel, wherein the first side oi the flexible display panel is fixed to the master shaft;

a support mechanism comprising a plurality of supporting members, wherein the supporting members are articulated each other;

wherein the supporting members are stored under the flexible display panel, when the flexible display panel is rolled up;

wherein the supporting members are leaned to a backside surface of the flexible display panel, when the flexible display panel is unrolled;

wherein a surface of the support mechanism comprises a guiding groove, and a guiding wheel is disposed at the second side of the flexible display panel, the guiding wheel is sliding inlaid in the guiding groove;

wherein the flexible display panel is rolling up and unrolling in response to sliding movements, in the guiding groove, of the guiding wheel.
