Any embodiment described herein as exemplary is not necessarily to be construed as preferred or advantageous over other embodiments. The following description is presented to enable any person skilled in the art to make and use the invention. In the following description, details are set forth for the purpose of explanation. It will be apparent to one of ordinary skill in the art that the present invention may be practiced without these specific details. In other instances, well-known structures and processes are not shown in detail to avoid obscuring the description of the present invention with unnecessary detail. Thus, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles disclosed herein.

It should be noted that the first direction and the second direction mentioned in the embodiments of the present application are perpendicular to each other, the first direction may be a column direction or a row direction, similarly, the second direction corresponds to a row direction or a column direction, and the first direction and the second direction may be interchanged in practical application. When the first direction is the x direction of the marks in fig. 1-7, that is, both the first LED lamp bead row and the second LED lamp bead row are a row of LED lamp beads, the second direction is the y direction of the marks in fig. 1-7, that is, the third LED lamp bead row is a row of LED lamp beads, the x direction in fig. 1-7 is the row direction, and the y direction is the column direction.

Referring to fig. 1, fig. 1 is a schematic diagram of an LED arrangement structure in the prior art. As shown in fig. 1, a plurality of light-emitting pixels 20 with the same structure are arranged on a PCB 10 in an array manner, each light-emitting pixel 20 is composed of three LED beads with different light-emitting colors, that is, a red LED bead, a blue LED bead and a green LED bead form one light-emitting pixel 20, so that the LED beads and the light-emitting pixels 20 are arranged on the PCB 10 in an array manner. Common-pole ends of all the LED lamp beads in each row of the light-emitting pixels 20 are electrically connected on the surface layer of the PCB board 10 to form a row scanning line, and non-common-pole ends of the LED lamp beads with the same light-emitting color in each row of the light-emitting pixels 20 are electrically connected on the inner layer or the bottom layer of the PCB board 10 through the through holes 101 in the PCB board 10 to form a row data line. The gate chip scans the pixels on the PCB 10 line by line through the scan lines 30, and the driving chip applies different currents through the data lines 40 to obtain different colors in each of the light emitting pixels 20, thereby obtaining a complete image on the PCB 10.

As can be seen from fig. 1, the number of the via holes 101 on the PCB 10 is determined by the number of the LED beads, and each light emitting pixel 20 needs three via holes 101 to implement the data line 40 to the inner layer or the bottom layer of the PCB 10.

Referring to fig. 2, fig. 2 is another schematic diagram of an LED arrangement structure in the prior art. As shown in fig. 2, a plurality of light-emitting pixels 20 with the same structure are arranged on the PCB 10 in an array manner, each light-emitting pixel 20 is composed of three LED beads with different light-emitting colors, i.e., a red LED bead, a blue LED bead and a green LED bead form one light-emitting pixel 20, so that the LED beads and the light-emitting pixels 20 are arranged on the PCB 10 in an array manner. The common-pole ends of all the LED lamp beads in each row of light-emitting pixels 20 are electrically connected to the inner layer or the bottom layer of the PCB board 10 through the via holes 101 on the PCB board 10 to form a row scan line, and the non-common-pole ends of the LED lamp beads with the same light-emitting color in each column of light-emitting pixels 20 are electrically connected to the surface layer of the PCB board 10 to form a column data line 40.

As can be seen from fig. 2, in order to avoid the problem of crossing between the scan line 30 and the data line 40, two data lines 40 in each column of light-emitting pixels 20 need to pass through between the positive and negative electrodes of one or more LED lamp beads. Although each light-emitting pixel 20 in fig. 2 only needs one via hole 101, due to the constraint of the wiring rule of the PCB board 10, the data line 40 passing through the space between the positive electrode and the negative electrode of the LED lamp bead will tend to increase the size of the LED lamp bead, thereby causing a sharp increase in cost. Taking a conventional COB chip 0408 (4 mil × 8 mil) as an example, the distance between the positive and negative electrodes of the COB chip is only 75um, and the pitch of the pads designed on the PCB 10 is smaller than the pitch of the pads on the COB chip to prevent the misalignment, so the value is generally 70um. According to the process level of the PCB 10, the line width and the line distance of the general routing lines are both 100um, and if two data lines 40 penetrate between the positive and negative electrodes of the COB chip, the distance between the positive and negative electrodes of the COB chip is at least 500um, and at this time, the COB chip must be far larger than the original 75um design size of the diode, so that the diode becomes very large, and the manufacturing cost rises sharply.
