Abstract

A touch panel includes a substrate, a touch device, a white translucent pattern, a color filter pattern and a reflection pattern. The substrate has a transparent region and an opaque region surrounding the transparent region. The touch device is disposed on the substrate in the transparent region. The white translucent pattern is disposed on the substrate in the opaque region. The color filter pattern stacks on the white translucent pattern in the opaque region. The reflection pattern stacks on the color filter pattern in the opaque region.

Claims

1. A touch panel, comprising:

a substrate, having a transparent region and an opaque region surrounding the transparent region;

a touch device, disposed in the transparent region of the substrate;

a white translucent pattern, disposed in the opaque region of the substrate;

a color filter pattern, disposed in the opaque region of the substrate and stacking on the white translucent pattern; and

a reflection pattern, disposed in the opaque region of the substrate and stacking on the color filter pattern.

2. The touch panel according to claim 1, wherein an optical density of the white translucent pattern is substantially in a range of 0.5 to 5.

3. The touch panel according to claim 1, wherein the white translucent pattern has an inclined sidewall.

4. The touch panel according to claim 1, wherein the color filter pattern comprises at least one of a red color filter pattern, a green color filter pattern and a blue color filter pattern.

5. The touch panel according to claim 1, wherein the white translucent pattern has at least one opening, and the color filter pattern is disposed on the white translucent pattern and the at least one opening.

6. A touch display panel, comprising:

a display panel, having a display surface; and

a touch panel, comprising;

a substrate, having a transparent region and an opaque region surrounding the transparent region, wherein the substrate has a surface facing the display surface of the display panel;

a touch device, disposed on the surface of the substrate and in the transparent region;

a white translucent pattern, disposed on the surface of the substrate and in the opaque region;

a color filter pattern, disposed on the surface of the substrate and in the opaque region,

wherein the color filter pattern stacks on the white translucent pattern; and

a reflection pattern, disposed on the surface of the substrate and in the opaque region, wherein the reflection pattern stacks on the color filter pattern.

7. The touch display panel according to claim 6, wherein an optical density of the white translucent pattern is substantially in a range of 0.5 to 5.

8. The touch display panel according to claim 6, wherein the white translucent pattern has an inclined sidewall.

9. The touch display panel according to claim 6, wherein the color filter pattern comprises at least one of a red color filter pattern, a green color filter pattern and a blue color filter pattern.

10. The touch display panel according to claim 6, wherein the white translucent pattern has at least one opening, and the color filter pattern is disposed on the white translucent pattern and the at least one opening.
