Embodiment Construction

[0021] The following examples are further explanations and supplements to the present invention, and do not constitute any limitation to the present invention.

[0022] Such as Figure 1 ~ Figure 4 As shown, the packaging structure of the novel LED display screen of the present invention includes a PCB board 10 , LED lamp beads 20 , a first packaging filler 30 and a second packaging filler 40 . The main gist of the present invention is that a second packaging filler 40 is provided between the LED lamp beads 20, and the second packaging filler 40 can block light, which can prevent the light emitted by two adjacent LED lamp beads 20 from being reflected on the display screen. Form a bright white line on the screen, and prevent the light emitted by the lamp beads at the edge from forming a bright white line at the edge of the display screen, thereby avoiding bright white lines at the joint when the packaging structure of multiple new LED displays is assembled. Streak phenomenon,...

Abstract

A packaging structure of a novel LED display screen comprises a PCB and a plurality of LED lamp beads arranged on the PCB in an array arrangement mode, first packaging filler is arranged between the LED lamp beads, and the first packaging filler, the LED lamp beads and the PCB are combined together. And second packaging filler is arranged on the first packaging filler, the second packaging filleris combined with the first packaging filler and is separated from the LED lamp beads and the PCB to form an integrated structure, and the second packaging filler is distributed among the LED lamp beads to enclose the LED lamp beads within the range of the second packaging filler. According to the invention, the second packaging filler for blocking light is arranged between the LED lamp beads, andthe LED lamp beads are respectively surrounded in the second packaging filler by utilizing the second packaging filler, so that the LED lamp beads at the edge position are blocked from emitting lightoutwards to avoid the phenomenon of light emitting, and two adjacent LED lamp beads are blocked from emitting light towards each other to avoid the phenomenon of interference. The novel packaging structure of the LED display screen has the advantages of being easy to machine and uniform in display.

Description

【Technical field】 [0001] The invention relates to a packaging structure of a novel LED display screen. 【Background technique】 [0002] The packaging structure of the new LED display usually includes a PCB board and LED lamp beads arrayed on the PCB board. After the LED lamp bead is packaged on the PCB board, it is usually sealed with epoxy resin glue, and the LED lamp bead is wrapped inside the epoxy resin glue to protect the LED lamp bead. In the prior art, the package structure of the new LED display screen is an integrated structure formed by combining PCB board, LED lamp beads and resin glue. When the LED lamp beads of the packaging structure of this new type of LED display are lit, the edge position will emit light. When the packaging structures of multiple new LED displays are spliced ​​together, bright white luminous lines will appear at the splicing places, which will greatly affect the display effect. 【Content of invention】 [0003] The purpose of the present i...
