In the related art, referring to the touch substrate shown in fig. 1, the first bridge 210 covers the substrate 100, the insulating layer 300 covers the first bridge 210, the second bridge 410 covers the insulating layer 300, the second bridge 410 has four turning points a, b, c, and d, the turning points a, b, c, and d are all right angles, and when an electrostatic current is generated, the current flows along the second bridge 410, and charge accumulation is likely to occur at the turning points a, b, c, and d, which causes the second bridge 410 to be subjected to electrostatic breakdown, so that the function failure occurs at the bridging position. The antistatic ability of bridging position is relatively poor, and touch substrate's life-span is lower, can not satisfy the requirement like longer products of replacement cycle such as on-vehicle display screen.
Based on this, referring to fig. 2 and fig. 3, a touch substrate according to an embodiment of the present invention includes a substrate 100, a first conductive layer 200, an insulating layer 300, and a second conductive layer 400, where the first conductive layer 200 includes a first bridge 210 and a plurality of first conductive blocks 220, two adjacent first conductive blocks 220 are connected through the first bridge 210, and the substrate 100 is covered with the first conductive layer 200; the insulating layer 300 covers one side of the first bridge 210 away from the substrate 100; the second conductive layer 400 includes a second bridge 410 and a plurality of second conductive blocks 420, two adjacent second conductive blocks 420 are connected by the second bridge 410, and projections of the second bridge 410 and the first bridge 210 cross each other in a direction perpendicular to the substrate 100.
Referring to fig. 3, a first inclined surface 310, a top surface 320 and a second inclined surface 330 connected in sequence are disposed on a side of the insulating layer 300 away from the first bridge 210, along a direction from the top surface 320 to the substrate 100, an end of the first inclined surface 310 away from the top surface 320 and an end of the second inclined surface 330 away from the top surface 320 both extend in a direction away from the top surface 320, the second bridge 410 includes a first inclined section 411, a connecting section 412 and a second inclined section 413 connected in sequence, the first inclined section 411 covers the first inclined surface 310, the connecting section 412 covers the top surface 320, and the second inclined section 413 covers the second inclined surface 330. Each turning point of the second bridge 410 is an obtuse angle, and when an electrostatic current occurs, the current flows smoothly along the second bridge 410, so that charge accumulation is not easy to occur, the antistatic capability of the bridging position can be improved, and the service life of the touch substrate is prolonged.
The first conductive layer 200 and the second conductive layer 400 may be made of indium tin oxide (ITO conductive layer), and the insulating layer 300 may be made of acrylic resin.
The sizes of the first bridge 210 and the second bridge 410 have a large influence on the appearance of the touch substrate, and if the sizes of the first bridge 210 and the second bridge 410 are too large, a user can see the structure at the bridging position with naked eyes, which affects the appearance of the touch substrate. Thus, the length of the projection of the second bridge 410 and the first bridge 210, which can be arranged in a direction perpendicular to the substrate 100, is less than 120 μm.
The smaller the included angle R1 between the first inclined surface 310 and the substrate 100 and the included angle R2 between the second inclined surface 330 and the substrate 100, the smoother the current flow along the second bridge 410, the less likely charge accumulation occurs, and the higher the antistatic capability of the second bridge 410 is; however, due to the size limitations of the first bridge 210 and the second bridge 410, the smaller the angle R1 between the first inclined surface 310 and the substrate 100 and the angle R2 between the second inclined surface 330 and the substrate 100 are, the thinner the insulating layer 300 is, the closer the distance between the first bridge 210 and the second bridge 410 is, and the closer the distance between the first bridge 210 and the second bridge 410 may cause charge interference between the first bridge 210 and the second bridge 410, and even cause the insulating layer 300 between the first bridge 210 and the second bridge 410 to be broken. Based on this, the included angle R1 between the first inclined surface 310 and the substrate 100 and the included angle R2 between the second inclined surface 330 and the substrate 100 may be 12 ° to 20 °, so as to improve the smoothness of the current flowing through the second bridge 410, and at the same time, avoid the occurrence of charge interference between the first bridge 210 and the second bridge 410, thereby improving the antistatic capability of the bridging position. The actual measurement shows that when the included angle R1 between the first inclined surface 310 and the base material 100 and the included angle R2 between the second inclined surface 330 and the base material 100 are both 12 ° to 20 °, the antistatic ability of the product can reach 25kV or more.
In order to ensure the coverage of the insulating layer 300 on the first bridge 210 and facilitate the arrangement and coating preparation of the insulating layer 300, referring to fig. 3, the bottom surface of the insulating layer 300 may be disposed to be attached to the substrate 100, and the first bridge 210 is embedded in the insulating layer 300. During production, the material of the insulating layer 300 is coated on the substrate 100 at the position of the first bridge 210 and is formed, so that the insulating layer 300 can be prepared, and the first bridge 210 can be completely covered.
In order to avoid interference between the first bridge 210 and the second bridge 410, referring to fig. 3, the width D of the top surface 320 of the insulating layer 300 is greater than the width D of the first bridge 210 along the width direction of the first bridge 210, and the second bridge 410 can completely cross the first bridge 210 without interfering with the first bridge 210, so as to improve the yield.
Referring to fig. 3, arc-shaped segments 414 may be disposed between the first inclined segment 411 and the connection segment 412, and between the connection segment 412 and the second inclined segment 413, so that the turns of the turns on the second bridge 410 are smooth, the second bridge 410 is prevented from being broken due to stress concentration, and the strength of the second bridge 410 can be ensured.
