The embodiment of the invention discloses a dotting method of an LED display screen, which can simplify the construction process of identification and improve the identification efficiency, and is favorable for accurately adjusting the identification method in the later period.
Example 1
Referring to fig. 1, fig. 1 is a schematic flow chart of a pointing method for an LED display screen according to an embodiment of the present invention. As shown in fig. 1, the method comprises the following steps:
step S1, designing a first-level software interface, wherein grid areas corresponding to the number and arrangement of LED chips on an LED lamp panel module are displayed on the first-level software interface, and carrying out first-level sequential numbering on grids of the grid areas; in specific implementation, the length of the grid area of the first-stage software interface is the number of each row of LED chips on the LED lamp panel module, and the width is the number of rows of the LED chips on the LED lamp panel module. As shown in the figure, the lattice area corresponding to the LED lamp panel module is 10 in length and 2 in width, and 20 LED chips are all arranged. The grid area is shown as: 20 grids, and are numbered in the order from the first row to the last row and from left to right, e.g., the first grid in the first row is numbered chip 1, the first grid is numbered chip 2, and so on, and the last grid in the last row is numbered chip 20.
And S2, designing a second-level software interface mapped with the LED chips on the LED lamp panel module, drawing color blocks corresponding to a certain LED chip, namely a bright spot area, on the second-level software interface, and lighting a lamp spot group on the LED lamp panel module controlled by the corresponding LED chip.
Step S3, according to the pin number and pin arrangement of the LED chips, drawing a bright spot area with the length of each row of pins of the LED chips and the width of each row of pins of the LED chips on a second-stage software interface by taking a coordinate origin as a starting point, mapping by a transmitter, so that all the lamp beads on an actual LED lamp panel module controlled by the LED chips are lighted, observing the lighted block positions of the lamp beads on the LED lamp panel module, and clicking the corresponding positions on a first-stage software interface according to the block positions, so as to realize the binding of the sequential addresses of the LED chips and the actual lighted addresses of the LED lamp panel module;
and S4, drawing out bright spot areas of the residual LED chips according to the number of chips and the chip placement sequence of the LED lamp panel module in a mode of the step S3 until the bright spot areas corresponding to all the LED chips on the LED lamp panel module are drawn out, observing the positions of blocks where the lamp beads on the LED lamp panel module are lighted, and clicking the corresponding positions on a first-stage software interface according to the positions of the blocks so as to realize the binding of the sequential addresses of the residual LED chips and the addresses where the LED lamp panel module is actually lighted.
Step S5, carrying out second-level sequential numbering on the LED lamp panel modules of which the bright spot areas are completely drawn according to the clicking sequence of the step S4 on the basis of the first-level sequential numbering;
in practical implementation, the LED chip is usually 16 pins, and the number of the pins in each row is 8, and the LED chip is divided into 2 rows; so according to this type of LED chip, a bright spot area having a length of 8 lattices and a width of 2 lattices should be drawn at the origin of the coordinates of the second level software interface, and the drawn bright spot area can be filled in with red for display at the second level software interface. Because the sequence of the LED chips produced by the lamp panel is fixed and the sequence cannot be known by normal means, when the bright spot area is drawn, human eyes are required to observe the position of a lighted block on the actual LED lamp panel module, and then click is carried out at the position corresponding to the position of the clicked block on the second-stage software interface; as shown in fig. 3, when the bright spot area of the first LED chip is drawn, the block position of the first row of the 6 th blocks, which is actually lit up on the LED lamp panel module, needs to be clicked at the position of the first level software interface, which is numbered as the chip 6, the position of the clicked chip 6 is displayed as "0", the "chip 6" represents the address where the LED lamp panel module is actually lit up, and the number "0" represents the sequential address of the first LED chip. Similarly, when the bright spot area of the second LED chip is drawn, the block position of the 10 th block of the second row needs to be clicked at the position of the chip 20 numbered on the first-level software interface, the clicked position of the chip 20 is displayed as "1", the chip 20 "represents the address where the LED lamp panel module is actually lighted, and the number" 1 "represents the sequential address of the second LED chip. Therefore, the binding of the sequence addresses of the remaining LED chips and the addresses of the actual lighting of the LED lamp panel module can be realized. We can record the order of the LED chips with the lamp panel module controller and exchange the chip addresses through this order in order to display a normal picture.
Step S6, firstly, acquiring coordinates corresponding to each pin of each LED chip according to the drawing sequence of the LED chips, wherein a coordinate calculation formula is as follows: x=l×m+n, where X represents a coordinate value, L represents a total pin number of the LED chip, M represents a second-stage sequential number corresponding to the LED chip, N is a pin number of the LED chip, and the second-stage sequential number starts counting from 0; all coordinates of all pins of the first LED chip are calculated, and then all coordinates of all pins of the remaining LED chips are calculated according to the drawing sequence, so that coordinate information of each lamp bead is obtained.
In specific implementation, assuming that the LED has 16 pins, after the first LED chip is drawn, the position of the lit block on the LED screen corresponds to the block labeled as "chip 2" on the first-stage software interface by observing manually, and then the coordinate value of the first pin of the first LED chip is x=16 (pin number) ×1 (counted from 0) +1=17, and the coordinate value of the last pin of the first LED chip is x=16×1+16=32. 17,18,19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29,30,31,32, for all pin coordinates corresponding to the first LED chip.
And S7, after the coordinates of the corresponding lamp points are assigned to all the chip pins, the calculated coordinate information of each lamp bead is sent to the lamp panel module controller at one time in a UDP (user datagram protocol) or serial port mode so as to realize the point tracing of the LED lamp panel module. In specific implementation, the lamp panel module controller may refer to an LED lamp panel with publication number CN112634813B, a module controller, a configuration method thereof, and a module controller in an LED display screen control system.
And S8, when the LED display screen is provided with a plurality of LED lamp panel modules, repeating the steps S1-S7 to trace points of the rest LED lamp panel modules so as to realize the tracing points of the whole LED display screen.
As described above, in the step S1, a software interface corresponding to the physical LED chip arrangement of the actual LED lamp panel module is designed so as to be in one-to-one correspondence when observed by human eyes; step S2, the related software interface is conveniently designed and mapped as the actual LED lamp panel module, so that the bright spot area can be conveniently drawn later; the step S3 and the step S4 are arranged, which block position on the LED lamp panel module is conveniently determined, which block position is actually controlled by all the LED chips, and the binding of the sequence address of the LED chips and the address which is actually lightened by the LED lamp panel module is determined by clicking the first-stage software interface. The setting in the step S5 can more intuitively display the position of the lighted block on the LED lamp panel module correspondingly controlled by a certain LED chip. And the setting of the step S6 is convenient for rapidly calculating the coordinates of the lamp points and improving the point tracing efficiency. And setting in the step S7 so as to store all the pin coordinate information, thereby realizing dotting.
