Touch display panel and touch sensing unit thereof

A touch display panel, comprising:

• a display panel, comprising a plurality of pixel region;
• a plurality of color filters disposed on the display panel;
• and
• a touch sensing unit, disposed on the display panel, the touch sensing unit comprising:
• a plurality of first sensing series disposed on the display panel, wherein each of the first sensing series comprises:
• a plurality of first transparent sensing pads disposed on the display panel along a first direction;
• and
• a plurality of non-transparent bridge lines disposed on the display panel along the first direction, each of the non-transparent bridge lines being respectively disposed between two adjacent first transparent sensing pads, each of the non-transparent bridge lines partially overlapping with two adjacent first transparent sensing pads, and each of the non-transparent bridge lines being electrically connected to two adjacent first transparent sensing pads, wherein a line width of each of the non-transparent bridge lines is substantially between 0.5 micrometers and 10 micrometers and an aperture ratio of the pixel region occupied by the non-transparent bridge lines is substantially between 0.1% and 5%;
• and
• a plurality of second sensing series disposed on the display panel along a second direction,
• wherein each of the color filters has a long axis and is located corresponding to one of the pixel regions, each of the non-transparent bridge lines and a part of the color filters partially overlap in a perpendicular projection direction, and each of the non-transparent bridge lines and the long axis of each of the color filters are disposed in a non-parallel manner with each other.
