Patent ID: 8054297

Claim:
A touch display panel, comprising: a first substrate; a second substrate; a third substrate, wherein the first substrate, the second substrate, and the third substrate are disposed in parallel, and the second substrate is disposed between the first substrate and the third substrate; a liquid crystal layer, disposed between the second substrate and the third substrate; a pixel array, disposed between the liquid crystal layer and the third substrate; an opposite electrode, disposed between the second substrate and the liquid crystal layer; a plurality of color filter patterns, wherein the plurality of color filter patterns and the opposite electrode are respectively disposed on opposite sides of the second substrate, and parts of the plurality of color filter patterns are piled to form a plurality of touch points; a first sensing electrode, disposed on the first substrate and facing the second substrate; and a second sensing electrode, covering the plurality of touch points and parts of the plurality of color filter patterns, wherein a height of the plurality of touch points is less than a gap between the first substrate and the second substrate.
