As shown in fig. 8, in an embodiment, the projections of the LED circuits 20 on the flexible transparent substrate 10 at both sides of the flexible transparent substrate 10 overlap each other.

That is to say, the LED lamp bead lines on the two sides of the flexible transparent substrate 10 do not correspond. By the arrangement, different and various LED lamp bead circuits can be arranged on two sides of the flexible transparent LED display screen, so that display screens with different specifications can be obtained, and different use requirements can be met.
As shown in fig. 10 and fig. 11, the cross-sectional areas of the electrode wire 21 designed by the grid and the electrode wire 110 designed by the solid line of the same polarity satisfy the following conditions:
A=x（B1+B2+B3+…+Bn）,x∈[0.5，3]；
wherein,
a is the total cross-sectional area of the electrode wire 100 in the solid line design;
bn (n =1.2.3 …) is the cross-sectional area of a certain grid line 21a or border line 21B in the grid-designed electrode line 21, (B1 + B2+ B3+ … + Bn) is the total cross-sectional area of the grid-designed electrode line 21.
Specifically, the same polarity means that the grid-designed electrode line 21 and the solid-line-designed electrode line 100 are both a positive electrode line or a negative electrode line. Even if the electrode wire 21 designed in the grid refers to the electrode wire 21 designed in the present application, the electrode wire 100 designed in the solid line is the electrode wire defined in the conventional technical solution, and please refer to fig. 10 specifically. And x belongs to [0.5, 3] means that the value of x is not less than 0.5 and not more than 3, namely x is not less than 0.5 and not more than 3.
Here, there is only one cross section of the electrode wire 100 designed by the solid line, so the area of the cross section is the total cross sectional area designed by the solid line, and the cross sectional area of the electrode wire 100 designed by the solid line is a. Since the total cross-sectional area of the grid-designed electrode line 21 is obtained by adding the cross-sectional areas of the plurality of grid lines 21a and the boundary lines 21B, the cross-sectional area of the grid-designed electrode line 21 is (B1 + B2+ B3+ … + Bn).
From the law of resistance R = ρ L/S (R: resistance; ρ: resistivity; L: length of conductor; S: cross-sectional area of conductor), it is known that the resistance of conductor is related to the cross-sectional area of conductor when the resistivity and the length of conductor are constant. It is well known that electrical resistance affects the conductivity of conductors. Is a key factor of (1). And a = x (B1 + B2+ B3+ … + Bn), x ∈ [0.5, 3 ]; this formula expresses the cross-sectional area of the grid-designed electrode wire 21 in relation to the cross-sectional area of the solid-line-designed electrode wire 100, and thus the above formula essentially represents the difference in the electrical conductivity of the grid-designed electrode wire 21 and the solid-line-designed electrode wire 100.
This wherein, inject the value range of x in 0.5~3 this interval, can make the LED display screen that adopts this application technical scheme (being the electrode line 21 of grid design), compare in the LED display screen that adopts traditional design (being the electrode line 100 of solid line design), on the basis that improves the LED display screen light transmissivity, make the LED display screen power supply performance of this application technical scheme and the LED display screen of traditional design keep unanimous basically, and then can ensure the display effect and the job stabilization nature of adopting the flexible transparent LED display screen of this application technical scheme.
It should be noted that, the electrode wire 100 designed by the solid line has a uniform cross-sectional area at each position, so the cross-sectional position of the electrode wire 100 designed by the solid line is not limited; in order to meet the design requirement of the conductivity of the electrode wire 21 designed in the grid, the total cross-sectional area of the electrode wire 21 designed in the grid at any position should also meet the requirement of the above formula, and the cross-sectional areas of the electrode wire 100 designed based on the solid line at all positions are consistent, so that the cross-sectional position of the electrode wire 21 designed in the grid is not limited.
Optionally, x ∈ [0.8, 1.5], that is, x is not less than 0.8 and not more than 1.5, that is, 0.5 ≦ x ≦ 1.5. In the range, the flexible transparent LED display screen can be ensured to have good light transmission, and the flexible transparent LED display screen can be ensured to have good display effect and working stability.
