Claim 5:
6. A touch display screen, comprising:
a display panel;
a touch electrode structure on a light-emitting side of the display panel; and
a bezel cover layer disposed on a side of the touch electrode structure facing away from the display panel; wherein:
the touch display screen has a display area and a bezel area, and the bezel area has a protrusion sub-area toward the display area;
the bezel cover layer is located in the bezel area;
the touch electrode structure comprises a plurality of leads, and the plurality of leads are arranged in the bezel area along an edge of the display area; and
a portion of each of the plurality of leads adjacent to the protrusion sub-area is a preset lead portion;
wherein the display panel further comprises an Organic Light Emitting Diode, OLED, display substrate and an encapsulation layer disposed on a light-emitting side of the OLED display substrate;
the display panel comprises a notch in an area corresponding to the protrusion sub-area; and
a side surface of the encapsulation layer close to the protrusion sub-area is a slope, and at least part of the preset lead portions are disposed on the slope;
wherein for preset lead portions disposed on the slope and with orthographic projections on the display panel not covered by the orthographic projection of the bezel cover layer on the display panel, an included angle between an upper surface of a side of each of said preset lead portions facing away from the display panel and a base surface of the OLED display substrate is within a preset range;
wherein a quantity of preset lead portions is N, and the N preset lead portions are arranged in sequence in a direction from the display area to the protrusion sub-area; wherein N is an integer larger than or equal to 2;
among the N preset lead portions, the orthographic projection of the bezel cover layer on the display panel covers an orthographic projection of x preset lead portions on the display panel, wherein x is an integer larger than or equal to 1 but smaller than N; and
each of (N-x) preset lead portions with an orthographic projection on the display panel not covered by the orthographic projection of the bezel cover layer on the display panel is a first preset lead portion, and a wire width of each first preset lead portion is smaller than a wire width of other portion, except the first preset lead portion, of a lead which each first preset lead portion belongs to.
