Wherein the first unit is an LED unit in a first direction; the second unit is an LED unit in a second direction.
Specifically, the number of the first units is the number of the LED units in the first direction, the number of the first LEDs is the number of the LEDs in the first direction, the LED lamp panel includes at least one first unit in the first direction, the number of the LEDs in the first direction in each first unit is the third number, and the third numbers corresponding to the first units can be calculated according to the relationship that the sum of the numerical values of the third numbers corresponding to all the first units is equal to the numerical value of the first LED number, wherein the numerical values of the third numbers are within a first preset range and may not be completely equal.

And S240, arranging at least one LED unit on the LED lamp panel according to the size information, the third quantity and the fourth quantity of the LED lamp panel and forming an LED array.
On one hand, on the other hand, the numerical values of the third quantities are summed to obtain the quantity of the first LEDs in the first direction, then the first distance between the LEDs in the first direction can be calculated according to the length size of the LED lamp panel in the first direction, and the arrangement mode of the LEDs in the first direction can be determined according to the first distance and the third quantities; on the other hand, the numerical values of the fourth quantities are summed to obtain the quantity of the second LEDs in the second direction, the second distance between the LEDs in the second direction can be calculated according to the width size of the LED lamp panel in the second direction, and the arrangement mode of the LEDs in the second direction can be determined according to the second distance and the fourth quantities.
According to the embodiment of the invention, the third number of each first unit is calculated according to the first unit number and the first LED number in the first direction, the fourth number of each second unit is calculated according to the second unit number and the second LED number in the second direction, wherein the third number is the LED number in the first direction in the first unit, the fourth number is the LED number in the second direction in the second unit, and then the arrangement scheme of the LED array is generated according to the dimension information of the LED lamp plate, each third number and each fourth number; on the other hand, each unit corresponds to a fourth quantity in the second direction, wherein each fourth quantity can be a naturally selected integer, so that the quantity of the LEDs in each unit in the second direction can meet the requirement of being an integer.

The third number can be 5 through calculation, and the number of the LEDs in the first direction in the 24 first units in the first direction is 5, where the arrangement is as follows: 24 × 5 — 120, i.e., the third number is 5 and the first number of cells is 24 in the first direction.
Similarly, since the sum of the values of the fourth numbers corresponding to all the second units in the second direction is equal to the value of the second LED number, b can be set1The number of the first units of each LED is n1Having b of2The number of the first units of each LED is n2… … and so on, each fourth quantity can be calculated from the numerical equivalence of the second number of LEDs as a function of the sum of the products of the fourth quantity and the second number of elements having the same fourth quantity. Wherein the numerical value of each fourth quantity is within a second preset range, n1、n2The sum of … … is N.
For example, let the second unit number be 16, the second LED number in the second direction be 93, and the second preset range of the fourth number be [1,6 ]. The fourth number may be 6, the number of LEDs in the second direction in 15 second cells in the second direction is 6, and the number of LEDs in the second direction in 1 second cell is 3, which is obtained by calculation, in this case: 15 × 6+1 × 3 ═ 93, i.e., in the second direction, the arrangement is made according to a fourth number of 6, a second number of units of 15, and a fourth number of 3, a second number of units of 1, respectively.

The embodiment of the invention can be a naturally selected integer by not limiting the third quantity to be completely equal numerical values, so that the quantity of the LEDs in the first direction in each unit can meet the requirement of being an integer; on the other hand, the fourth numbers are not limited to be completely equal, but may be integers selected naturally, so that the number of LEDs in the second direction in each unit can satisfy the requirement of being an integer.

The first driving voltage of each LED unit may be determined according to the number of LEDs (third number) of each LED unit in the first direction, for example, according to a lookup table, where a corresponding relationship between the third number and the first driving voltage is recorded on the lookup table.
For example, in one LED unit, driving the LEDs in the LED unit with the first driving voltage may be as shown in fig. 4.

In addition, due to the fact that the fault range is small, time and labor are saved for troubleshooting of the fault LED.
In one embodiment, the LED unit includes a driving circuit and at least one second lamp group arranged along a second direction, and the second lamp group includes at least two LEDs arranged in series in the second direction, and the generating method in the embodiment of the present invention may further include: and determining a second driving voltage used by the driving circuit for driving the LED according to the fourth quantity.

The second driving voltage of each LED unit may be determined according to the number of LEDs (fourth number) of each LED unit in the second direction, for example, according to a lookup table, where a corresponding relationship between the fourth number and the second driving voltage is recorded on the lookup table.
For example, in one LED unit, driving the LEDs in the LED unit with the second driving voltage may be as shown in fig. 5. The LED unit 102 includes a driving circuit 104 and 4 second lamp groups 103 arranged along a second direction (a column direction in the figure), each second lamp group 103 includes 3 LEDs 101 connected in series, and the number of LEDs in the second direction (a fourth number) is 3, so that a second driving voltage when the fourth number is 3 can be determined according to a lookup table, and each second lamp group 103 is driven by the second driving voltage.

In addition, due to the fact that the fault range is small, time and labor are saved for troubleshooting of the fault LED.
In one embodiment, the driving method shown in fig. 4 may be applied to a part of LED units on the LED array, and the driving method shown in fig. 5 may be applied to another part of LED units on the LED array, where the driving method shown in fig. 4 is required to satisfy that the first lamp group includes at least two LEDs; when the driving method as shown in fig. 5 is adopted, it is necessary that the second lamp set includes at least two LEDs.

For example, assuming that the size information of the LED lamp panel is 211.14 × 140.76, where 211.14 is a length dimension in the first direction, 140.76 is a width dimension in the second direction, and the first number of LEDs is 120, then the first pitch is calculated as about 1.76 by dividing the length dimension by the first number of LEDs.
And S620, calculating a second interval of the LEDs according to the width size of the LED lamp panel in the second direction and the fourth quantity.
Wherein the second pitch is an LED pitch in the second direction. And summing the fourth quantities to obtain a second LED quantity, wherein the second LED quantity is the LED quantity in the second direction, and dividing the width size of the LED lamp panel in the second direction by the second LED quantity to obtain a second interval. For example, assume that the size information of the LED panel is 211.14 × 140.76, where 211.14 is the length dimension in the first direction and 140.76 is the width dimension in the second direction. The second number of LEDs is 93 and the length dimension is then divided by the second number of LEDs to obtain a second pitch, which is calculated to be about 1.52.
Step S630, generating an arrangement scheme of the LED arrays according to the first distance, the third numbers, the second distance, and the fourth numbers.
Specifically, the first pitch is a distance between the LEDs in the first direction, the third number is a number of LEDs in the first direction in the first unit, and the LED array in the first direction in each first unit can be determined according to the first pitch and each third number; the second pitch is a distance between the LEDs in the second direction, the fourth number is a number of LEDs in the second direction in the second unit, and the array of LEDs in the second direction in each second unit is determined according to the second pitch and each fourth number.
