Abstract

There is disclosed a polio case including a back cover coupled to a rear surface of a mobile terminal, a quick cover connected to a predetermined portion of the back cover, to cover a front surface of the mobile terminal, a touch unit provided in an inner portion of the quick cover, the touch unit formed of a conductive material, wherein a touch sensor provided in the front surface of the mobile terminal contacts with the touch unit, when the quick cover is closed, and capacity of the touch sensor changes. The polio case may provide the display unit with a screen matching a shape of the quick cover.

First claim

What is claimed is:

1. A case for a mobile terminal comprising:
a back cover to couple to a first surface of the mobile terminal;
a quick cover to couple to the back cover, and a back surface of the quick cover contacting at least a portion of a second surface of the mobile terminal at a closed position;
a quick window at the quick cover;
at least one touch unit at the back surface of the quick cover, the at least one touch unit being formed of a conductive material; and
at least one ground unit at a front surface of the quick cover, the ground unit connected to the at least one touch unit via a ground line,
wherein when the quick cover is at the closed position, the at least one touch unit contacts a touch sensor at the second surface of the mobile terminal,
wherein when a body part of a user touches the at least one ground unit a capacity changes of at least one point of the touch sensor where the at least one touch unit contacted the touch sensor, and
wherein an arrangement of the at least one touch unit at the back surface of the quick cover includes information of a shape of the quick window.

2. The case of claim 1 , wherein the arrangement and a size of the at least one touch unit is based on at least one of a color of the quick cover and a design of the quick cover.

3. The case of claim 1 , wherein the at least one touch unit is provided around the quick window.

4. The case of claim 1 , further comprising:
a ground unit at the quick cover to couple to a ground of the mobile terminal.

5. The case of claim 1 , further comprising:
a ground unit at the back cover to couple to a ground of the mobile terminal.

6. The case of claim 1 , further comprising:
a ground unit at the quick cover to electrically connect to the touch unit,
wherein the touch unit is to be grounded when a touch member touches the ground unit and the capacity of the touch sensor at the mobile terminal changes.

7. The case of claim 1 , further comprising:
a ground unit at the back cover to electrically connect to the touch unit,
wherein the touch unit is to be grounded when a touch member touches the ground unit and the capacity of the touch sensor at the mobile terminal changes.

8. The case of claim 1 , wherein the touch unit includes user identity information.

9. The case of claim 1 , wherein each of the at least one ground unit connects to each of the at least one touch unit.

10. A mobile terminal comprising:
a case;
a display unit at the case, the display unit including a touch sensor and a screen; and
a controller to activate a first area of the screen and to inactivate a second area of the screen during the touch sensor senses at least a plurality of touch inputs,
wherein the at least a plurality of touch inputs placed at the second area;
wherein the controller determines a size, a shape, a color, a design and contents of the first area of the screen based on positions and total numbers of the plurality of touch inputs, and
wherein the controller controls the first area of the screen when a capacity of at least one point of the touch sensor where sensing the at least one of plurality of touch inputs changes.

11. The mobile terminal of claim 10 , wherein the controller to display content at the first area of the screen without displaying content at the second area of the screen when the touch sensor senses the plurality of touch inputs.

12. The mobile terminal of claim 10 , wherein the characteristics include positions and total numbers of the plurality of touch inputs.

13. The mobile terminal of claim 10 , further comprising:
a ground at the housing; and
a ground terminal to couple to the ground.

14. The mobile terminal of claim 10 , wherein the controller to implement a preset function based on a touch input at the touch sensor.
