[0029] like Figure 3 and 4As shown, a binding alignment structure includes an alignment mark 10 and a plurality of binding pins 20, wherein the alignment mark 10 is arranged next to the plurality of binding pins 20, and the alignment mark 10 is composed of four right-angled fan-shaped blocks 101, wherein the four right-angled fan-shaped blocks 101 are arranged at four corners along a first direction and a second direction, and the right angles of the four right-angled fan-shaped blocks 101 are arranged relative to each other to form a cross-shaped gap 102.

[0030] The binding alignment structure of the utility model adopts four of the right-angled fan-shaped blocks 101 to form the alignment mark 10. When the display screen is bound to the circuit board, the cross-shaped gap 102 between the four right-angled fan-shaped blocks 101 is used as the alignment recognition area of ​​the CCD camera, that is, the alignment mark 10 actually provides the CCD camera with alignment recognition not the four right-angled fan-shaped blocks 101 but the cross-shaped gap 102. When the alignment recognition area is the same, the material required to make the four right-angled fan-shaped blocks 101 is less than that of the traditional cross-shaped alignment mark, which can reduce the cost of the product and bring about considerable profit increase when the display screen is mass-produced.

[0031] like Figure 2 and 5 As shown, assuming that the cross-shaped gap 102 has the same area as the traditional cross-shaped alignment mark, and both adopt the size specifications of length L=3mm, height H=3mm, and line width D=1mm, then the total area S1 of the four right-angle fan-shaped blocks 101 is S1=π*1 2 =3.14mm 2 , while the total area of ​​the traditional cross-shaped alignment mark is S2 = 1*3 + 1*3 - 1*1 = 5mm 2 It can be seen that the material cost required to make the four right-angle fan-shaped blocks 101 is reduced by 37.2%.

[0032] In this embodiment, there are two alignment marks 10 , and the two alignment marks 10 are respectively disposed on two opposite sides of the plurality of binding pins 20 .

[0033] Each of the right-angled fan-shaped blocks 101 includes a first straight side, a second straight side and an arcuate side, wherein one end of the first straight side is connected to one end of the second straight side, and the first straight side is perpendicular to the second straight side; one end of the arcuate side is connected to the other end of the first straight side, and the other end of the arcuate side is connected to the other end of the second straight side.

[0034] The binding pin 20 has a length direction and a width direction. The binding pin 20 has a first size in the length direction and a second size in the width direction. The first size is greater than the second size.

[0035] The length direction of the binding pin 20 is parallel to the first direction, and the width direction of the binding pin 20 is parallel to the second direction; a plurality of the binding pins 20 are arranged in sequence along the second direction.

[0036] Preferably, the first direction is perpendicular to the second direction. In this embodiment, the first direction is the long side direction of the display screen, and the second direction is the short side direction of the display screen.

[0037] In this embodiment, the right-angle sector block 101 may be, but is not limited to, an ITO block or a metal block. Embodiment 2

[0038] like Figure 6 and 7 As shown, a display screen includes a display area 101 and a non-display area 102, wherein the non-display area 102 is located outside the display area 101; the non-display area 102 is provided with a binding area 103 on one side edge of the display screen, and the binding alignment structure described in Example 1 is provided in the binding area 103.

[0039] The display screen further includes a circuit board 30 , and the circuit board 30 is bound and connected to the binding alignment structure of the binding area 103 .

[0040] Specifically, the CCD camera is first used to photograph and identify the alignment mark 10 of the binding alignment structure, and the cross-shaped gap 102 in the alignment mark 10 is identified. The cross-shaped gap 102 is used to complete the alignment between the multiple binding pins 20 and the circuit board 30, and then the ACF film is used to bond the circuit board 30 to the multiple binding pins 20, so that an electrical connection is formed between the circuit board 30 and the multiple binding pins 20.

[0041] The display screen further includes a driving chip 40 . The driving chip 40 is disposed on the non-display area 102 and located between the binding area 103 and the display area 101 .
