Abstract

A touch integrated panel includes a first substrate having a first outer surface and a first inner surface where a thin film transistor array is formed, a second substrate having a second outer surface and a second inner surface, and a liquid crystal layer sandwiched between the first inner surface and the second inner surface, wherein a touch sense pattern for sensing touch operations performed on the panel and a key sense pattern for sensing whether a function key is touched are formed on the first outer surface or the second outer surface.

Claims

1. A touch integrated panel, comprising:

a first substrate having a first outer surface and a first inner surface wherein a thin film transistor array is formed on the first inner surface,

a second substrate having a second outer surface and a second inner surface, and

a liquid crystal layer sandwiched between the first inner surface and the second inner surface,

wherein a touch sense pattern for sensing touch operations and a key sense pattern for sensing whether a function key is touched are formed on the first outer surface or the second outer surface.

2. The touch integrated panel as claimed in claim 1, wherein an edge of the second substrate protrudes with respect to an edge of the first substrate at the same side.

3. The touch integrated panel as claimed in claim 2, wherein the key sense pattern is formed on a protrusion area of the second substrate with respect to the first substrate.

4. The touch integrated panel as claimed in claim 3, wherein the extended length of the protrusion area of the second substrate with respect to the first substrate is 0.5-10 mm.

5. An electronic device, comprising:

the touch integrated panel as claimed in claim 1;

a backlight arranged at the side of the first outer surface or the second outer surface of the touch integrated panel; and

a housing covering the touch integrated panel and the backlight,

wherein a function key icon representing the function key is formed at a position of a surface of the housing corresponding to the position of

6. The electronic device as claimed in claim 5, wherein light emitted from the backlight passes through the touch integrated panel and the housing to illuminate the function key icon.

7. A method of manufacturing a touch integrated panel, comprising:

forming a thin film transistor array on a first substrate;

providing a second substrate;

injecting liquid crystal between a surface of the first substrate where the thin film transistor array is formed and an inner surface of the second substrate, and adhering the first substrate to the second substrate; and

forming a touch sense pattern and a key sense pattern on an outer surface of the first substrate which faces away from the second substrate or on an outer surface of the second substrate which faces away from the first substrate.

8. The method as claimed in claim 7, wherein for each touch integrated panel an edge of the second substrate protrudes with respect to an edge of the first substrate at the same side.

9. The method as claimed in claim 8, wherein the key sense pattern is formed on a protrusion area of the second substrate with respect to the first substrate.

10. The method as claimed in claim 9, wherein the extended length of the protrusion area of the second substrate with respect to the first substrate is 0.5-10 mm.
