Touch display panel and display device

A touch display panel, wherein the touch display panel performs touch control based on an active stylus, and the touch display panel comprises:

• a display substrate;
• and
• a plurality of touch conductive layers, located at a display side of the display substrate;
• wherein an orthographic projection of the plurality of touch conductive layers on the display substrate is divided into a plurality of touch units arranged in an array along a first direction and a second direction, one touch unit of the touch units comprises a plurality of touch sub-units arranged in n rows by n columns, wherein n is an integer greater than or equal to 2;
• the first direction intersects with the second direction, an extension direction of each row of the touch sub-units is the first direction, and an extension direction of each column of the touch sub-units is the second direction;
• a width h1 of one touch sub-unit of the touch sub-units in the first direction, a width h2 of the touch sub-unit in the second direction, and a tip diameter D of the active stylus satisfy:
