Abstract

An input-sensor-integrated liquid crystal display panel has a first substrate, a second substrate, and a liquid crystal layer. The first substrate has at least one pixel controlling circuit, and the second substrate has a touch-detecting circuit. A color filter layer is formed between the first and second substrates, and the liquid crystal layer is filled in space formed by the first and second substrates.

Claims

1. An input-sensor-integrated liquid crystal display panel, comprising:

a first substrate having at least one pixel controlling circuit;

a second substrate having a touch-detecting circuit and being positioned on top of the first substrate; and

a liquid crystal layer filled between the space formed by the first substrate and the second substrate.

2. The input-sensor-integrated liquid crystal display panel of claim 1 wherein the first substrate further comprises a color filter.

3. The input-sensor-integrated liquid crystal display panel of claim 1 wherein the second substrate further comprises a color filter.

4. The input-sensor-integrated liquid crystal display panel of claim 3 wherein the color filter is formed on the touch-detecting circuit.

5. The input-sensor-integrated liquid crystal display panel of claim 3 wherein the color filter and the touch-detecting circuit are formed on different sides of the second substrate.

6. The input-sensor-integrated liquid crystal display panel of claim 1 wherein the touch-detecting circuit is positioned on an inner side of the second substrate facing the first substrate.

7. The input-sensor-integrated liquid crystal display panel of claim 1 wherein the touch-detecting circuit is positioned on an outer side of the of the second substrate.

8. The input-sensor-integrated liquid crystal display panel of claim 1 wherein the first substrate dis-coincide with the second substrate and has at least one protrusion.

9. The input-sensor-integrated liquid crystal display panel of claim 8 wherein the protrusion includes a plurality of signal connecting contacts.

10. The input-sensor-integrated liquid crystal display panel of claim 1 further comprising a polarizer.

11. The input-sensor-integrated liquid crystal display panel of claim 10 wherein the touch-detecting circuit is positioned between the second substrate and the polarizer.

12. The input-sensor-integrated liquid crystal display panel of claim 1 wherein the touch-detecting circuit is a resistance detecting circuit, capacitance detecting circuit, sound wave detecting circuit, or optical detecting circuit.
