Touch display panel, display device and touch panel

A display device, comprising a touch display panel, and a circuit board;

• wherein
• the touch display panel comprises:
• an array substrate and an opposite substrate, each including a base substrate;
• a plurality of block touch electrodes spaced apart from each other on the array substrate, or on the opposite substrate;
• a conductive shielding layer insulated from the block touch electrodes;
• wherein the conductive shielding layer is at a side, away from the array substrate, of the opposite substrate, or at a side, away from the opposite substrate, of the array substrate;
• and an orthographic projection of the conductive shielding layer on the base substrate is at least in a gap between orthographic projections of the block touch electrodes;
• the conductive shielding layer is connected with a control circuit of the circuit board;
• and
• the control circuit is configured to:
• control the conductive shielding layer to be grounded during a display period;
• and apply a control signal to the conductive shielding layer during a touch period, to avoid an interference signal except a touch signal.

A touch panel, comprising:

• an array substrate and an opposite substrate, each including a base substrate;
• a plurality of block touch electrodes spaced apart from each other on the array substrate, or on the opposite substrate, wherein the block touch electrodes are self-capacitance electrodes;
• and
• a conductive shielding layer on the base substrate, wherein the conductive shielding layer is insulated from the block touch electrodes,
• wherein the conductive shielding layer is at a side, away from the array substrate, of the opposite substrate, or at a side, away from the opposite substrate, of the array substrate, and an orthographic projection of the conductive shielding layer on the base substrate is at least in a gap between orthographic projections of the block touch electrodes.
