Abstract

An on-cell Touch Screen Panel (TSP) Active Matrix Organic Light Emitting Diode (AMOLED) structure is provided. The on-cell TSP AMOLED structure includes an AMOLED, a display driver for driving the AMOLED, a display driver reinforcing material positioned at an upper part of the display driver, and a window positioned at an upper part of the display driver reinforcing material, wherein a resin or Optical Clear Adhesive (OCA) is applied between an upper surface of the display driver reinforcing material and a lower surface of the window. Therefore, separation and twist of a display driver reinforcing material can be prevented.

Claims (34)

1. An on-cell Touch Screen Panel (TSP) Active Matrix Organic Light Emitting Diode (AMOLED) structure, the structure comprising:

an AMOLED;

a display driver positioned outside a peripheral edge in plan view of an encap glass of the AMOLED, for driving the AMOLED;

a display driver reinforcing material positioned at an upper part of the display driver;

a polarizing plate disposed on and essentially coextensive with an upper surface of the encap glass of the AMOLED, wherein the display driver reinforcing material contacts a peripheral edge of the polarizing plate and a peripheral edge of the encap glass, and wherein an upper surface of the polarizing plate and an upper surface of the display driver reinforcing material form one substantially planar surface;

a resin or Optical Clear Adhesive (OCA) disposed on the substantially planar surface and extending over the polarizing plate and the display driver reinforcing material; and

a window comprising glass or acryl and extending over an upper part of the display driver reinforcing material, the polarizing plate, and the encap glass, wherein a surface of the window is substantially parallel to the encap glass,

wherein the resin or Optical Clear Adhesive (OCA) is disposed between the substantially planar surface and a lower surface of the window, and

wherein the structure is configured such that a load of the window is dispersed to the display driver reinforcing material.

2. The structure of claim 1 , wherein the resin or OCA applied between the upper surface of the display driver reinforcing material and the lower surface of the window is also applied between an upper surface of the polarizing plate and the lower surface of the window.

3. The structure of claim 1 , further comprising a TSP Indium Tin Oxide (ITO) pattern formed between an upper surface of the AMOLED and a lower surface of the polarizing plate.

4. The structure of claim 1 , wherein the AMOLED comprises a Low Temperature Polycrystalline Silicon (LTPS) glass and the encap glass.

5. The structure of claim 4 , further comprising a Flexible Printed Circuit Board (FPCB) connected to a main board to transfer a control signal to the display driver, which is formed at an upper surface of the LTPS glass and at side portion of the display driver.

6. The structure of claim 4 , wherein the display driver is positioned at an upper surface of one side of the LTPS glass.

7. The structure of claim 1 , wherein the display driver comprises a Liquid Crystal Display (LCD) Driver Integrated circuit (LDI).

8. The structure of claim 1 , wherein the display driver reinforcing material comprises polyethylene terephthalate (PET).

9. The structure of claim 1 , wherein the window comprises one of glass and acryl.

10. The structure of claim 1 , further comprising a sponge disposed at a lower surface of the AMOLED.

11. An on-cell Touch Screen Panel (TSP) Active Matrix Organic Light Emitting Diode (AMOLED) structure, the structure comprising:

a window comprising glass or acryl;

an AMOLED including a Low Temperature Polycrystalline Silicon (LTPS) glass and an encap glass;

a polarizing plate disposed between the window and the encap glass, and essentially coextensive with an upper surface of the encap glass;

a display driver configured to drive the AMOLED and positioned outside a peripheral edge in plan view of the encap glass and at an upper surface of one side of the LTPS glass; and

a display driver reinforcing material positioned between the window and the display driver, a side of the display driver reinforcing material abutting a peripheral edge of the polarizing plate and a peripheral edge of the encap glass,

wherein an upper surface of the polarizing plate and an upper surface of the display driver reinforcing material form one substantially planar surface,

wherein a surface of the window is substantially parallel to and extends over the encap glass and the display driver reinforcing material,

wherein a resin or Optical Clear Adhesive (OCA) is applied between an upper surface of the substantially planar surface and a lower surface of the window, and

wherein the structure is configured such that a load of the window is dispersed to the display driver reinforcing material.

12. The structure of claim 11 , wherein the display driver reinforcing material contacts a peripheral edge of the polarizing plate.

13. The structure of claim 11 , further comprising a TSP Indium Tin Oxide (ITO) pattern formed between an upper surface of the encap glass and a lower surface of the polarizing plate.

14. The structure of claim 11 , further comprising a Flexible Printed Circuit board (FPCB) connected to a main board to transfer a control signal to the display driver, which is formed at an upper surface of the LTPS glass and at side portion of the display driver.

15. The structure of claim 11 , wherein the display driver reinforcing material comprises polyethylene terephthalate (PET).

16. The structure of claim 11 , wherein the window comprises one of glass and acryl.

17. The structure of claim 11 , further comprising a sponge disposed at a lower surface of the LTPS glass.
