LED lamp panel and production process

Abstract

The invention relates to the field of a small-spacing LED display screen. The invention relates to an LED lamp panel and a production process. According to one scheme of the LED lamp panel, the LED lamp panel comprises a circuit board, LED lamp beads and dry film layers, wherein the circuit board comprises a first line layer and an insulation layer; the LED lamp beads are in conductive connectionwith the first line layer; the dry film layers are fixed on the circuit board; the LED lamp beads and the dry film layers are positioned on the same side of the insulation layer; and a height by whichthe LED lamp beads protrude out of the insulation layer is smaller than a height by which the dry film layers protrude out of the insulation layer. The LED lamp panel solves the technical problem that in the prior art, LED lamp beads are easy to damage by collision in the carrying and assembling process, and achieves the technical effects of convenient and economic protection structure of the LEDlamp beads and capacity of effectively protecting the LED lamp beads.

Description

technical field [0001] The invention relates to the field of small-pitch LED display screens, in particular to an LED lamp board and a manufacturing process. Background technique [0002] Small-pitch LED display refers to the indoor LED display with LED dot pitch below P2.5, mainly including P2.5, P2.0, P1.8 and P1.5 LED display products, with the small-pitch LED display With the rapid development of screens, due to the need for splicing, the LED light panels are designed with a frameless structure. After the display splicing is completed, the LED light panels located at the edge of the cabinet are vulnerable to bumps or impacts, resulting in damage or fall-off of the LED lamp beads. The maintenance and replacement of LED lamp beads is very difficult. If the pad is damaged, the LED lamp beads there cannot be repaired and replaced.

AI Technical Summary

Problems solved by technology

[0002] Small-pitch LED display refers to indoor LED displays with LED point spacing below P2.5, mainly including P2.5, P2.0, P1.8 and P1.5 LED display products. With the small-pitch LED display With the rapid development of screens, due to the need for splicing, the LED light panels are designed with a frameless structure. After the display splicing is completed, the LED light panels located at the edge of the cabinet are vulnerable to bumps or impacts, resulting in damage or fall-off of the LED lamp beads. The maintenance and replacement of LED lamp beads is very difficult. If the pad is damaged, the LED lamp beads there cannot be repaired and replaced.

[0003] There are not many LED displays equipped with protective light devices in the existing market, and some only adopt the method of adding accessories for protection, that is, install a protective edge on the LED light panel during the handling process, and then remove the accessories during the splicing process of the display screen. The operation process of this measure is cumbersome and will lead to an increase in labor costs. Therefore, it is necessary to design and develop a convenient and economically feasible LED light panel protection structure
