After the preset backlight brightness matrix is obtained, for convenience of subsequent calculation, one column of data needs to be selected as sample data, and the first column of the sample data may be selected, or the data of the second column or other columns of the sample data may be selected. Taking the selection of the first column of data as an example, the preset target backlight matrix is shown in the following table:

TABLE 2 Preset target backlight matrix

Step S101, obtaining a preset target backlight brightness matrix.

In this embodiment, after the preset target backlight luminance matrix is obtained, the next step is waited for.

Step S102a, sorting the brightness values in the preset target backlight brightness matrix in order from small to large to obtain an intermediate backlight brightness matrix.

In order to determine the lowest brightness value, the highest brightness value, and the intermediate brightness value, the brightness values in the preset target backlight brightness matrix need to be sorted, so that the lowest brightness value, the highest brightness value, and the intermediate brightness value are conveniently obtained.

Step S102b, respectively determining a minimum brightness value and a maximum brightness value in the intermediate backlight brightness matrix, setting the minimum brightness value as the minimum brightness value and the maximum brightness value as the maximum brightness value, and setting the brightness value between the minimum brightness value and the maximum brightness value as the intermediate brightness value.

After the preset target backlight brightness matrix is sorted, the lowest brightness value, the highest brightness value and the middle brightness value can be obtained for the use of the subsequent steps.

Step S102, calculating density values of luminance values in the preset target backlight luminance matrix according to a first preset rule and the preset target backlight luminance matrix to obtain a first group of sample density values, where the first preset rule includes a sample density calculation formula.

In this embodiment, after the preset target backlight luminance matrix is obtained, the density value of each luminance value in the preset target backlight luminance matrix needs to be calculated according to a first preset rule, so as to obtain a first group of sample density values. As can be known from step S101b, the luminance values in the preset target backlight luminance matrix are composed of three parts, which are the lowest luminance value, the highest luminance value and the middle luminance value, so that the first set of sample density values can be composed of the initial density value, the ending density value and the middle density value, wherein the middle density value is calculated according to the sample density calculation formula, and the first preset rule can further include a first preset sub-rule in addition to the sample density calculation formula, the first preset sub-rule is used for obtaining the initial density value and the ending density value.

The first predetermined sub-rule is used to set the starting density value and the ending density value, which may be a preferred value selected according to the conventional dot design experience of the diffuser plate, in this embodiment, the starting density value may be 0.2, the ending density value may be 0.5, the starting density value corresponds to the lowest luminance value, and the ending density value corresponds to the highest luminance value. The sample density calculation formula is used to calculate the intermediate luminance value, which may be (luminance value to be calculated-lowest luminance value)/(highest luminance value-lowest luminance value) × (end density value-start density value) +0.2, for example, a density value with a luminance value of 312 is calculated as follows: (312 + 280)/(340 + 280) ((0.5-0.2) + 0.2) ═ 0.420588235, i.e. the density value with the luminance value of 312 is 0.420588235, for the sake of calculation convenience, two bits after the decimal point are taken, i.e. the density value with the luminance value of 312 is 0.42, the corresponding density values are calculated for other intermediate luminance values in the preset target luminance matrix by using the sample density calculation formula, and the following table can be obtained:

brightness value	Density value
		287	0.2
294	0.26
		312	0.42
312	0.42
		320	0.49
321	0.5
		321	0.5

The density values in the table are the first set of sample density values.

In an embodiment, as illustrated in fig. 2, the first preset rule further includes a first preset sub-rule, the first set of density values includes a start density value, an end density value, and an intermediate density value, and the step S102 may include steps S201-S202.

Step S201, obtaining a pre-configured start density value and an end density value, and corresponding the start density value to the minimum luminance value and the end density value to the maximum luminance value.

In this embodiment, the start density value and the end density value are pre-configured, and in this embodiment, the start density value is 0.2, and the end density value is 0.5, which may be other values, and after determining the start density value and the end density value, only the lowest luminance value in the preset target backlight luminance matrix needs to be corresponding to the start density value, and the maximum luminance value needs to be corresponding to the end density value, so as to calculate the density value of the intermediate luminance value in the following process.

Step S202, calculating an intermediate density value of the intermediate luminance values according to the sample density calculation formula so as to form the first set of sample density values with the start density value and the end density value, wherein the intermediate density values correspond to the intermediate luminance values one to one.

The sample density calculation formula is specifically described in step S102, and is not described here, and in this step, only the intermediate density value of the intermediate luminance value needs to be calculated according to the sample density calculation formula.

In one embodiment, as illustrated in FIG. 3, the step S202 may include steps S301-S302.

Step S301, obtaining the lowest brightness value, the highest brightness value, the start density value, and the end density value.

The sample density formula includes a minimum brightness value, a maximum brightness value, an initial density value and an end density value, and therefore, the minimum brightness value and the maximum brightness value in the preset target backlight brightness matrix and the initial density value and the end density value obtained in the previous step need to be obtained first, so as to perform the subsequent steps.

Step S302, obtaining an intermediate brightness value to be calculated, and substituting the lowest brightness value, the highest brightness value, the start density value, and the end density value into the sample density calculation formula to calculate a density value of the intermediate brightness value to be calculated.

As can be seen from table 2, the middle luminance value includes 9 luminance values, which are 287, 294, 312, 320, 321, and 321, respectively, a luminance value to be calculated, which may be 312, needs to be obtained first, and then the lowest luminance value 287, the highest luminance value 321, the start density value 0.2, and the end density value 0.5 are substituted into the sample density calculation formula to calculate the density value with the luminance value of 312, which includes the following specific calculation processes: (brightness value-lowest brightness value to be calculated)/(highest brightness value-lowest brightness value) (end density value-start density value) +0.2, namely (321 + 280)/(340 + 280) ((0.5-0.2) + 0.2) ═ 0.420588235, namely, the density value with the brightness value of 321 is 0.420588235, and two digits after the decimal point are taken, namely, the density value with the brightness value of 321 is 0.42. And after the density value with the brightness value of 321 is calculated, continuously acquiring the brightness value to be calculated, and then calculating according to a sample density calculation formula until all the intermediate brightness values are calculated.

And 103, performing curve fitting on the first group of sample density values according to a preset corresponding relation to obtain a fitting density calculation formula.

In this embodiment, the sample density calculation formula calculates the intermediate brightness value according to the brightness value of the lamp bead, the initial density value and the final density value to obtain the first set of sample density values. The preset corresponding relationship may be a relationship between a value of X and the density value, for example, when the value of X is 0, the density value is 0.2, and when the value of X is 1, the density value is 0.26, and the specific corresponding relationship may refer to the following table:

value of X	Density value
			0	287
1	294
		2	312
3	312
		4	320
5	321
		6	321

TABLE 3

Performing curve fitting on the corresponding relationship between the value of X and the density value in table 3 to obtain a fitting density calculation formula, which is a functional relationship between Y and X, in this embodiment, the fitting density calculation formula is:

Y＝0.2194x⁶-4.0917x⁵+28.944x⁴-95.958x³+145.34x²-67.45x+287，

wherein, Y is the density value, that is, the density value of the brightness value is converted into the functional relation between Y and X.

And step S104, obtaining a mesh point side length formula according to an actual density calculation formula and the fitting density calculation formula.

In the present embodiment, the mesh point of the diffuser plate is generally composed of many small squares, each square has a certain distance therebetween, as shown in fig. 4, there are four squares with a side length of R in fig. 4, which are respectively squares O1, square O2, square O3 and square O4, wherein point O1, point O2, point O3 and point O4 are respectively midpoints of squares O1, O2, O3 and O4, a rhombus a is obtained by connecting midpoints of each square, as can be seen from the figure, four vertexes of the rhombus a are respectively located among squares O1, O2, O3 and O4, and a portion where the rhombus a coincides with squares O1, O2, O3 and O4 is exactly equal to the area of a square with a side length of R, therefore, the area of the middle portion to be filled by the formula enclosed by four squares and the area of the rhombus can be found out, that is, the square area formula in this embodiment is the square of the side length, i.e. R ^2, and the diamond area formula is the multiplier of the diagonal divided by 2, i.e. Px Py/2, so the density Y ^2/Px Py/2, and the fitting density formula in step S103 is:

Y＝0.2194x⁶-4.0917x⁵+28.944x⁴-95.958x³+145.34x²-67.45x+287，

therefore, through the actual density formula and the fitting density formula, a formula of the side length of the square, namely a formula of the side length of the mesh point, namely:

R^2/Px*Py/2＝0.2194x⁶-4.0917x⁵+28.944x⁴-95.958x³+145.34x²-67.45x+287，

and Px and Py are constants, so that a functional relation between the net point side length and X can be obtained, and the functional relation is a net point side length formula.

And S105, calling target software according to the network point side length formula to output a network point diagram.

In this embodiment, after the dot length formula is obtained, the formula may be input into the designated software, so that the software may simultaneously output the corresponding dot images according to the dot length. For example, the VBA program in the CAD software may be used to put the dot side length formula as a code into the VBA program, so that the dot map may be automatically generated.

In one embodiment, as illustrated in FIG. 5, the step S105 may include steps S501-S502 b.

Step S501, the target software is called.

After the dot side length formula is obtained, target software can be called for subsequent operation.

Step S502, configuring the mesh point side length formula in a pre-configured code, and configuring the code configured with the mesh point side length formula in the target software to obtain a mesh point diagram, wherein the pre-configured code comprises a central coordinate of the target software, and the central coordinate is used for matching with the mesh point side length formula to obtain the mesh point diagram.

For example, in the CAD software, the CAD may have a default X axis, Y axis, and origin, and the coordinate of the origin needs to be determined, so that the CAD generates a dot diagram according to the dot side length formula and the origin coordinate, inputs the dot side length formula into the target software, for example, into the CAD, and automatically generates the dot diagram by using a VBA program in the CAD.

Step S502a, executing the target software to cause the target software to run the preconfigured code to output the mesh graph.

After the pre-configured code is input into the target software, the target software can be operated, so that the target software outputs a network diagram.

Step S502b, acquiring a mesh point diagram output by the target software.

After the target software outputs the mesh point diagram, the mesh point diagram can be directly acquired so as to facilitate other subsequent operations of the user.

The embodiment of the invention obtains the mesh point side length formula by replacing the three formulas of the sample density formula, the fitting density formula and the actual density formula, and connects the mesh point side length formula with the function, wherein the mesh point side length formula is only related to the density, and the density is related to the backlight brightness value, so that the mesh point can be obtained only by obtaining the backlight brightness value, and meanwhile, when the mesh point design drawing needs to be replaced, the new mesh point design drawing can be obtained only by obtaining the new backlight brightness value again, the design period is short, and meanwhile, the complicated optical simulation process is not needed.
