Background

The LED display screen is composed of a plurality of lamp bodies integrated on the lamp panel module, each lamp body is integrated with three monochromatic lamp chips (red, yellow and blue) and a power supply chip, and when the LED display screen is used, different monochromatic lamps on each lamp body are driven to be lightened, so that various pictures can be displayed on the LED display screen. The LED display screen has strong competitive strength in the market by virtue of the advantages of high brightness, real color recovery, seamless splicing, point-by-point correction and the like, has more opportunity to enter high-end markets such as a control room, a television station studio, a command and dispatch center, a large conference center and the like, and even has the possibility of gradually replacing the market status of the traditional indoor DLP rear projection and LCD splicing wall in the future.

When designing a lamp panel in the prior art, in order to ensure the uniformity of three colors of red, green and blue on the whole screen surface, the direction requirements of each lamp body are consistent. According to the lamp panel principle, the three pins of RGB of the same row of lamps are respectively connected and connected to the driving signal end of the driving chip, and the power supply pins of the same row of lamps are all connected and connected to the row signals.

In the prior art, along with the fact that semiconductor technology and manufacturing process are mature day by day, the technology of the LED display screen is expanded continuously, and the pursuit of higher-level LED display products puts higher requirements on the manufacturing process, even approaches the technical limit of the manufacturing process continuously, so that the volume of the lamp body is smaller and smaller. Under the intensive condition of lamp body, the lamp face can't walk around the pad and walk the line safely, can only pass through the hole and trade the layer and link to each other. Because each lamp needs to make at least 4 through holes, the quantity and the density of the holes are huge, the holes are almost distributed on the whole lamp surface, and even if layers are changed, signals can not bypass the through holes. Effective line width and safe interval are walked the line and are linked to each other and receive the processing ability's of board factory restriction, make the lamp plate design degree of difficulty increase, can't accomplish even.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

The implementation of the present embodiment is described in detail below with reference to specific drawings.

As shown in fig. 1, the present embodiment provides an LED lamp panel module, which includes a lamp panel 1, a plurality of lamp bodies 2 are arranged on the lamp panel 1 in rows and columns, and via holes are formed (the via holes are mature structures in the prior art, and are not shown in the drawings).

As shown in fig. 3, the first monochromatic light 21, the second monochromatic light 22, the third monochromatic light 23 and the power chip 24 are sequentially arranged on each lamp body 2 in a clockwise direction, each of the first monochromatic light, the second monochromatic light, the third monochromatic light and the power chip corresponds to one pin, and the four pins are sequentially connected to form a rectangle. It should be noted that the first monochromatic light 21, the second monochromatic light 22, and the third monochromatic light 23 in this embodiment correspond to three colors of red, yellow, and blue, respectively, the first, second, and third are only used for distinguishing, and do not correspond to a color sequence one by one, for example, the first, second, and third may correspond to red, yellow, and blue in sequence, or may correspond to red, blue, yellow in sequence, or other corresponding manners.

For convenience of description, assuming that the direction in which the second monochromatic lamp 22 is directed toward the first monochromatic lamp 21 is the installation direction of the lamp body 2 (i.e., the direction indicated by the arrow in fig. 1), the angle between the installation directions of any two adjacent lamp bodies 2 on the lamp panel 1 is 90 ° or 180 °.

In fig. 1, different line filling patterns represent different monochromatic lamps, and it can be known from the observation of the distribution of the monochromatic lamps, because the included angle between the two lamp bodies 2 at the adjacent positions in the installation direction is not 0 °, that is, the monochromatic lamps and the power chip 24 at the two lamp bodies have different positions, when the included angle between the two lamp bodies in the installation direction is 90 ° or 180 °, like the two adjacent lamp bodies 2 at the upper left corner in fig. 1, the second monochromatic lamps 22 at the two lamp bodies are in an adjacent state, and the pins corresponding to the second monochromatic lamps 22 can be directly connected with each other through wires and share one via hole.

The same can be deduced, the relation between all other adjacent lamp bodies 2 on whole lamp plate 1. Due to the special property of the rectangle, as long as the installation direction included angle of the adjacent lamp bodies 2 is ensured to be 90 ° or 180 °, the adjacent relationship between the two is as follows:

1. one of the first monochromatic lamp 21, the second monochromatic lamp 22 and the third monochromatic lamp 23 is adjacent, and corresponding pins can be directly wired and connected with each other;

2. the respective power chips 24 are adjacent, and the corresponding pins can be directly wired and connected to each other.

According to the above inference, the stitches in fig. 2 can be understood corresponding to the distribution mode of fig. 1, fig. 1 is equivalent to the portion of the upper left 4 (lamp body 2) multiplied by 4 (lamp body 2) in fig. 2, it is possible to correspond two by two and route interconnection in the mode of illustration, it is only necessary to connect any stitch in the outside to connect to the chips corresponding to both simultaneously, the two stitches can share one via hole, the number of via holes is greatly reduced, not only the design difficulty and the processing difficulty of the via hole itself are reduced, but also fewer via holes mean that the lamp panel 1 has more effective areas, larger effective line width and safety space can be provided, the wiring is easy to design, and the design difficulty of the lamp panel is reduced.

Purely from the design, the installation direction of the lamp body 2 at the upper left corner shown in fig. 1 (i.e., the direction shown in fig. 3) is set to be 0 °, and on the premise that the arrangement mode is satisfied, the lamp body 2 of the lamp panel 1 can have three installation angles, namely, clockwise 90 °, counterclockwise 90 ° and 180 °, but in actual installation, the complexity of installation can be greatly improved in four installation directions, so that the design mode with only two angles is adopted in the embodiment, and the installation difficulty is reduced as much as possible on the premise that the beneficial effects are achieved. As shown in the figure, on lamp plate 1 of this embodiment, 2 installation directions of half lamp body are 0, and half is anticlockwise 90, and the two interval sets up.

As shown in fig. 1, according to the special property of the rectangle and the above rules, in the combination of four lamp bodies 2 which are arbitrarily located at four vertexes of the rectangle and adjacent to each other on the lamp panel 1, the installation direction included angle of the two lamp bodies 2 located at opposite angles is 0 °.

According to the deduction, the lamp body 2 at the center of the lamp panel 1 is provided with a pin and the adjacent lamp body 2 on four sides, the pins are connected with the adjacent lamp body 2 in a wiring mode and share a via hole, the lamp body 2 is located at the edge of the lamp panel 1, the pins on the outer side of the lamp body need to occupy a via hole independently, and the number of the via holes is smaller than that of the lamp bodies 2 on the whole and is larger than half of that of the lamp bodies 2. Through rough calculation, the number of the via holes of 3/8 can be saved approximately by adopting the mode in the embodiment, the area saved by the part is enough to route wires between two diagonal via holes, and the distance is increased by √ 2 times compared with the original distance, so that the wires have enough line width and keep safe distance with the via holes, and a decisive basis is laid for reducing the design difficulty of the whole lamp panel 1. So directly set up the signal line on lamp plate 1 in this embodiment, need not to improve current processing preparation level and can reach the designing requirement.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
