Abstract

A portable terminal, including a first housing including opposing first and second sides, a second housing including opposing first and second sides, a hinge connecting the first sides of the first and second housings, a flexible display including a first end disposed in the second side the first housing, a second end disposed in the second side of the second housing, and a driver configured to drive the display, wherein the first housing and the second housing are configured to rotate on the hinge to form an angle in therebetween such that a corresponding portion of the display is exposed, and the driver is configured to output driving signals corresponding to the angle to the flexible display, such an image is displayed on the exposed portion of the flexible display.

First claim

What is claimed is:

1. A portable terminal, comprising:
a first housing comprising opposing first and second sides;
a second housing comprising opposing first and second sides;
a hinge connecting the first sides of the first and second housings;
a flexible display comprising a first end disposed in the second side of the first housing, a second end disposed in the second side of the second housing; and
a driver configured to drive the flexible display,
wherein the first housing and the second housing are configured to rotate on the hinge to form an angle therebetween such that a corresponding portion of the flexible display is exposed,
wherein, when the angle between the first and second housings is zero (0) degrees, a center portion of the flexible display is disposed on at least a portion of outer surfaces of the second sides of the first and second housings, and
wherein the driver is configured to output driving signals corresponding to the angle to the flexible display, such an image is displayed on the exposed portion of the flexible display.

2. The portable terminal of claim 1 , wherein the driver is configured to output driving signals corresponding to a year, date, day of the week, time, and weather, when the angle between the first and second housings is zero (0) degrees.

3. The portable terminal of claim 1 , further comprising:
a first driving axle disposed in the second side of the first housing and connected to the first end of the flexible display; and
a second driving axle disposed in the second side of the second housing and connected to the second end of the flexible display.

4. The portable terminal of claim 3 , wherein the first driving axle and the second driving axle are configured to rotate in first and second directions, to thereby wind and unwind the flexible display.

5. The portable terminal of claim 3 , wherein each of the first driving axle and the second driving axle comprises an elastic body to bias the rotations thereof in one of the first or second directions.

6. The portable terminal of claim 5 , wherein the hinge comprises:
a first hinge axle connected to the first housing;
a second hinge axle connected to the second housing; and
a hinge body connecting the first and second hinge axles, wherein the first and second housings are configured to respectively rotate on the first hinge axle and the second hinge axle.

7. The portable terminal of claim 6 , wherein the first hinge axle and the second hinge axle are configured to have frictional forces greater than the biasing forces of the elastic bodies.

8. The portable terminal of claim 1 , further comprising:
a recess formed in an outer surface of the second housing;
a support member disposed in the recess; and
a rotation member connecting a first side of the support member to the recess, wherein the support member is configured to rotate on the rotation member to be selectively extended from the second housing.

9. The portable terminal of claim 8 , wherein the first side of the support member is disposed adjacent to the second side of the second housing.

10. The portable terminal of claim 9 , wherein the support member is configured to rotate on the rotation member and configured to protrude out to support the second housing when the angle between the first and second housings is greater than about 90 degrees.

11. The portable terminal of claim 1 , wherein edges of the second sides of first and second housings that contact the flexible display are curved, to reduce bending of the flexible display.

12. The portable terminal of claim 1 , further comprising a timing controller configured to receive an angle information corresponding to the angle between the first and second housings and output corresponding image signals to the driver, wherein the driver is configured to generate the driving signals in response to the image signals.
