[0020] The first sub-tapes 4 are connected to the inner surfaces of the first mother tape 1 and the second mother tape 2 respectively through the tape edge 3, the second sub-tape 5 is connected to the inner surface of the first sub-tape 4 through the tape edge 3, the inner wall of the tape edge 3 is provided with a second connecting edge 7, the inner wall of the tape edge 3 and the outer walls of the first sub-tape 4 and the second sub-tape 5 are provided with a first connecting edge 6, and the first connecting edge 6 and the second connecting edge 7 are made of the same material, and the first connecting edge 6 and the second connecting edge 7 are both semicircularly arranged, the rear walls of the first mother tape 1, the second mother tape 2, the first sub-tape 4 and the second sub-tape 5 are all integrally connected with a protruding edge 8, and the outer corner of the protruding edge 8 is set at a right angle, the mother tape and the sub-tape can be set to intercept the tape of the corresponding area according to the area of the display, so as to avoid waste caused by too large or too small display area;
[0021] The outer walls of the first mother tape 1 and the second mother tape 2 are both connected with heat dissipation aluminum strips 9. The heat dissipation aluminum strips 9 are evenly arranged on the outer walls of the first mother tape 1 and the second mother tape 2, and the heat dissipation aluminum strips 9 are "V"-shaped. The first mother tape 1 and the second mother tape 2 are connected by the heat dissipation aluminum strips 9.

[0022] Working principle: For this type of light-shielding tape for displays, first, when a large area of tape is used for the display, the first mother tape 1 and the second mother tape 2 can be connected to each other through a "V"-shaped heat dissipation aluminum strip 9. The principle is that the V"-shaped teeth allow the parts of the mother tapes to fit tightly together, which can increase the area of tape used for the display;
[0023] Then, when the display area is too small, the mother tape or the first sub-tape 4 or the second sub-tape 5 can be torn off through the protruding edge 8 to obtain a relatively smaller tape, and the remaining tape can continue to be used for a smaller part of the display;

It not only conducts heat, but also facilitates the rapid transfer of heat, thereby avoiding high temperatures in the display during use of the tape, and is beneficial to the durability of the display during use. At the same time, the black PET layer 15 can make the tape appear black as a whole to avoid light.
