Lateral mounting type full-color LED package and LED transparent screen

Abstract

The invention relates to a lamp bar type LED transparent display screen, and provides a lateral mounting type full-color LED package and an LED transparent screen. Lateral mounting type LED packaged LED lamp beads are designed to be of a structure of a surface mount device (SMD), and each lateral mounting type LED packaged LED lamp bead comprises an electrode metal sheet, a main body frame, LED chips, multiple leads and package colloid. According to the full-color LED display device, the size is small, a lamp bar PCB of the LED transparent display screen is parallel to the sight line of the human eyes due to the fact that a lateral mounting mode is adopted, the penetration rate of a screen body of the LED transparent display screen is not limited by the size of the PCB and reaches a higher value, the point spacing distance specification can be smaller, and the reliability is higher; when display modules are assembled, high-speed automated mounting of an SMT can be achieved, the production efficiency is high, and quality control is easy to achieve.

Description

technical field [0001] The invention relates to the technical field of a light emitting diode (LED) display screen, in particular to a light bar type LED (Light-Emitting Diode) transparent display screen. Background technique [0002] In recent years, with the development of electronic circuit surface mount technology SMT (Surface Mount Technology), products related to surface mount SMD (Surface Mounted Devices) light-emitting diode (LED) displays have been widely used. Among them, LED transparent screens are favored by many commercial centers because of their decoration, display and good light transmission. LED display manufacturers have designed a variety of LED display screens based on the existing surface mount (SMD) LED packaging forms. Transparent screen, such as the Chinese patent application number 201410332313.7, the application date is July 14, 2014, the name of the invention is transparent screen, the main content relates to a transparent screen, including an oute...

AI Technical Summary

Problems solved by technology

[0003] refer to figure 1 , figure 1 It is a schematic diagram showing the technical process of the existing LED transparent screen. Since the light-emitting surface of the patch LED lamp beads used in the existing LED transparent screen products is relatively parallel to the patch surface of the PCB board, the patch surface needs to occupy the necessary PCB. Board space, two adjacent PCB boards, the distance between the patch LED lamps is greater than 14 mm to ensure the light transmittance of the transparent screen, therefore, the existing transparent screen is difficult to achieve a smaller spacing and the light transmittance is limited by the PCB board area limit

[0004] refer to figure 2 , figure 2 It is a schematic diagram showing the first improved technical process of the existing LED transparent screen. In order to improve the high light transmittance of the transparent screen, the first improved technical process adopts the method of reducing the area of ​​the strip PCB board as much as possible, but reduces the area of ​​the strip PCB. The area of ​​the PCB board will lead to a compact circuit design on the PCB board, causing problems such as circuit heat dissipation, which not only increases the difficulty of design, but also the slender strip PCB board is more likely to be bent and damaged during production and installation. Transparent screen products need to pass through Add light-transmitting panels to stabilize the strip PCB structure to prevent damage, which in turn increases the weight of the transparent screen structure and the difficulty of installation and maintenance, and it is difficult to adapt to various complex installation conditions and environments

[0005] refer to image 3 , image 3 It is a schematic diagram showing the second improved technical process of the existing LED transparent screen. The second improved technical process adopts the way that the strip PCB board is perpendicular to the light-emitting surface of the LED lamp, but this technical process is obviously difficult to integrate the SMD LED Lamp beads realize SMT high-speed automatic patching, which can only be welded by hand or using special fixtures, which leads to a significant reduction in production efficiency and difficulties in quality control
