Abstract

A touch screen panel display device is provided. The touch screen panel display device includes a Y-touch sensor bonding pattern having a bonding portion bonded to a touch screen Flexible Printed Circuit Board (FPCB), an X-touch sensor bonding pattern positioned toward the touch screen FPCB further than the bonding portion of the Y-touch sensor bonding pattern and having a bonding portion bonded to the touch screen FPCB, and a touch screen FPCB having an X-contact point portion contacting the bonding portion of the X-touch sensor bonding pattern and a Y-contact point portion contacting the bonding portion of the Y-touch sensor bonding pattern. Thereby, an Anisotropic Conducting Film (ACF) swelling failure occurring as a heat is again applied to a location at which bonding is already complete can be prevented.

Claims

1. A touch screen panel display device, the device comprising:

a Y-touch sensor bonding pattern having a bonding portion bonded to a touch screen Flexible Printed Circuit Board (FPCB);

an X-touch sensor bonding pattern positioned toward the touch screen FPCB further than the bonding portion of the Y-touch sensor bonding pattern and having a bonding portion bonded to the touch screen FPCB; and

a touch screen FPCB having an X-contact point portion contacting the bonding portion of the X-touch sensor bonding pattern and a Y-contact point portion contacting the bonding portion of the Y-touch sensor bonding pattern.

2. The device of claim 1, wherein the touch screen FPCB comprises:

an X-contact point forming portion in which the X-contact point portion is formed; and

a Y-contact point forming portion protruded further than the X-contact point forming portion and in which the Y-contact point portion is formed.

3. The device of claim 2, wherein a U-shaped cut is formed between the X-contact point forming portion and the Y-contact point forming portion.

4. A touch screen panel display device, the device comprising:

an X-touch sensor bonding pattern having a bonding portion bonded to a touch screen FPCB;

a Y-touch sensor bonding pattern positioned toward the touch screen FPCB further than the bonding portion of the X-touch sensor bonding pattern and having a bonding portion bonded to the touch screen FPCB; and

a touch screen FPCB having an X-contact point portion contacting the bonding portion of the X-touch sensor bonding pattern and a Y-contact point portion contacting the bonding portion of the Y-touch sensor bonding pattern.

5. The device of claim 4, wherein the touch screen FPCB comprises:

a Y-contact point forming portion in which the Y-contact point portion is formed; and

an X-contact point forming portion protruding further than the Y-contact point forming portion and in which the X-contact point portion is formed.

6. The device of claim 5, wherein a U-shaped cut is formed between the X-contact point forming portion and the Y-contact point forming portion.

7. A touch screen panel display, the display comprising:

a display unit for displaying an image;

an Indium Tin Oxide (ITO) film arranged above the display unit;

a protector for protecting the touch screen panel display from the outside; and

a Flexible Printed Circuit Board (FPCB) arranged between the ITO film and the protector,

wherein the protector includes a Y-touch sensor bonding pattern arranged at a lower surface of the protector and having a bonding portion for bonding to a Y-contact point portion of the FPCB,

wherein the ITO film includes an X-touch sensor bonding pattern arranged at an upper surface of the ITO film and having a bonding portion for bonding to an X-contact point portion of the FPCB, and

wherein the bonding portion of the Y-touch sensor bonding pattern is spaced apart from the bonding portion of the X-touch sensor bonding pattern such that a line perpendicular to the bonding portion of the Y-touch sensor bonding pattern and passing through the bonding portion of the Y-touch sensor bonding pattern does not intersect the bonding portion of the X-touch sensor bonding pattern.

8. The display of claim 7, wherein the FPCB comprises a connector for connecting the FPCB to a controller.

9. The display of claim 8, wherein the bonding portion of the Y-touch sensor bonding pattern is disposed closer to the connector than the bonding portion of the X-touch sensor bonding pattern.

10. The display of claim 8, wherein the bonding portion of the X-touch sensor bonding pattern is disposed closer to the connector than the bonding portion of the Y-touch sensor bonding pattern.
