Abstract

A touch screen, a method of manufacturing the same, and a mobile terminal having the same for minimizing a border area of the mobile terminal are provided. The touch screen includes a flexible display panel including an active area in which an image is displayed and a wiring area including signal lines for transmitting data corresponding to the image, and a flexible touch panel attached to a front surface of the display panel and including a touch detection area at which touch sensors for detecting a touch are positioned and a wiring area at which signal lines for transmitting a touch signal are positioned, wherein the wiring area of the display panel and the wiring area of the touch panel are bent so as not to be parallel to the active area and the touch detection area.

Claims (34)

1. A touch screen, comprising:

a flexible display panel comprising an active area in which an image is displayed and a wiring area comprising signal lines for transmitting data corresponding to the image;

a flexible touch panel attached to a front surface of the display panel and comprising a touch detection area at which touch sensors for detecting a touch are positioned and a wiring area at which signal lines for transmitting a touch signal are positioned; and

a bracket positioned at a lower end portion of the flexible display panel and for flatly fixing the flexible display panel,

wherein the wiring area of the display panel and the wiring area of the touch panel are bent so as not to be parallel to the active area and the touch detection area, and

wherein the bracket comprises a groove for inserting the wiring area of the display panel and the wiring area of the touch panel.

2. The touch screen of claim 1 , further comprising:

a protection window attached to the flexible touch panel and for protecting the flexible touch panel.

3. The touch screen of claim 1 , wherein the wiring area of the display panel and the wiring area of the touch panel are positioned between an outer side surface of the bracket and an inner side surface of a case of the touch screen.

4. The touch screen of claim 1 , wherein the protection window comprises a groove for inserting the wiring area of the display panel and the wiring area of the touch panel.

5. The touch screen of claim 1 , wherein the protection window and the bracket are made of a flexible material.

6. The touch screen of claim 1 , wherein in the flexible touch panel, a driving channel for recognizing the abscissa and a detecting channel for recognizing the ordinate are formed with a metal mesh.

7. A mobile terminal in which a flexible touch screen is installed, wherein the touch screen comprises:

a flexible display panel comprising an active area in which an image is displayed and a wiring area at which signal lines for transmitting data corresponding to the image are positioned; and

a flexible touch panel attached to a front surface of the display panel and comprising a touch detection area at which touch sensors for detecting a touch are positioned and a wiring area at which signal lines for transmitting a touch signal are positioned,

wherein the wiring area of the display panel and the wiring area of the touch panel are bent so as not to be parallel to the active area and the touch detection area,

wherein the touch screen further comprises a bracket positioned at a lower end portion of the flexible display panel and for flatly fixing an active area of the flexible display panel, and

wherein the bracket comprises a groove for inserting the wiring area of the display panel and the wiring area of the touch panel.

8. The mobile terminal of claim 7 , wherein the touch screen further comprises a protection window attached to the flexible touch panel and for protecting the flexible touch panel.

9. The mobile terminal of claim 7 , wherein the wiring area of the display panel and the wiring area of the touch panel are positioned between an outer side surface of the bracket and an inner side surface of a case of the mobile terminal.

10. The mobile terminal of claim 7 , wherein the protection window comprises a groove for inserting the wiring area of the display panel and the wiring area of the touch panel.

11. The mobile terminal of claim 7 , wherein the protection window, the bracket, and a case of the mobile terminal are made of a flexible material.

12. The mobile terminal of claim 7 , wherein in the flexible touch panel, a driving channel for recognizing the abscissa and a detecting channel for recognizing the ordinate are formed with a metal mesh.

13. A method of manufacturing a touch screen, the method comprising:

stacking a flexible display panel comprising an active area in which an image is displayed and a wiring area at which signal lines for transmitting data corresponding to the image are positioned and a flexible touch panel comprising a touch detection area at which touch sensors for detecting a touch are positioned and a wiring area at which signal lines for transmitting a touch signal are positioned;

bending the wiring area of the display panel and the wiring area of the touch panel so as not to be parallel to the active area and the touch detection area;

disposing a bracket for fixing the display panel at a lower end portion of the display panel; and

bending the wiring area of the display panel and the wiring area of the touch panel at a side surface of the bracket,

wherein the bracket comprises a groove for inserting the wiring area of the display panel and the wiring area of the touch panel.

14. The method of claim 13 , wherein the bending of the wiring area of the display panel and the wiring area of the touch panel so as not to be parallel to the active area and the touch detection area comprises:

stacking the bracket comprising both side end portions at a lower end portion of the display panel; and

inserting the wiring area of the display panel and the wiring area of the touch panel into the groove of the bracket.

15. The method of claim 13 , further comprising:

attaching a protection window for protecting the touch panel to an upper end portion of the touch panel.
