Touch display panel, method for manufacturing the same, and display apparatus

A display apparatus, comprising a touch display panel and a power supply component electrically connected to the touch display panel;

• wherein the touch display panel comprises:
• a display substrate and a touch layer;
• wherein
• the display substrate comprises a display region and a non-display region surrounding the display region;
• and
• the touch layer comprises a plurality of touch units and a plurality of touch lines;
• wherein
• the plurality of touch units are arranged in an array on the display substrate and at least partially disposed in the display region;
• the plurality of touch lines are disposed on the display substrate, and each touch line of the plurality of touch lines is connected to at least one of the plurality of touch units and configured to electrically connect a touch unit connected thereto to a touch integrated circuit;
• the plurality of touch lines at least comprise a first trace and a second trace which are disposed in the non-display region;
• and
• the display substrate comprises a conductive layer disposed in the non-display region;
• wherein at least one first through hole and at least one second through hole are defined in the conductive layer, the first through hole being within an orthographic projection of the first trace on the conductive layer, the second through hole being within an orthographic projection of the second trace on the conductive layer, and a total opening area of the first through hole in per unit area of the first trace being greater than a total opening area of the second through hole in per unit area of the second trace.

A method for manufacturing a touch display panel, comprising:

• providing a display substrate, wherein the display substrate comprises a display region and a non-display region surrounding the display region, the display substrate comprises a conductive layer disposed in the non-display region, and at least one first through hole and at least one second through hole are defined in the conductive layer;
• and
• forming a touch layer by forming a plurality of touch units and a plurality of touch lines on the display substrate, wherein the plurality of touch units are arranged in an array on the display substrate and disposed in the display region;
• each touch line of the plurality of touch lines is connected to at least one of the plurality of touch units and configured to be connected to a touch integrated circuit;
• and the plurality of touch lines at least comprise a first trace and a second trace which are disposed in the non-display region, the first through hole being within an orthographic projection of the first trace on the conductive layer, the second through hole being within an orthographic projection of the second trace on the conductive layer, and a total opening area of the first through hole in per unit area of the first trace being greater than a total opening area of the second through hole in per unit area of the second trace.
