Touch display panel and driving method thereof

摘要

A touch display panel, including first electrode patterns, second electrode patterns, active elements, third electrode patterns and fourth electrode patterns is provided. The second electrode patterns and the first electrode pattern are set to form pixel areas. Each of the active elements is disposed in one of the pixel areas and electrically connected to the corresponding first electrode pattern and second electrode pattern. The third electrode patterns are arranged along a direction of an arrangement direction of the second electrode patterns and divide the second electrode patterns into groups, wherein each third pattern covers columns of the pixel areas. The fourth electrode patterns are electrically insulated to the third electrode patterns. Each fourth electrode pattern is disposed in one of the pixel areas and electrically connected to the corresponding active element. A driving method of a touch display panel is also provided.
