With the continuous development of upstream chip and packaging technology, the process of direct plug-in products has become very mature. Direct-plug products have good weather resistance, but their display performance cannot meet the requirements of end customers; surface-mount products have excellent display performance, but their weather resistance and other aspects are unsatisfactory. If there is a product that can meet the two conditions of excellent display performance and excellent weather resistance at the same time, it will definitely change the industry landscape.
The background of the three-in-one direct-plug display
Faced with the challenges of surface-mount products, manufacturers of direct-plug display screens with mature technology did not sit still. On the one hand, they used lamp beads with smaller radius to make outdoor display products with smaller spacing; on the other hand, companies represented by Jinhuaguang Technology improved the direct-plug technology and sealed three RGB chips into a direct-plug lamp, and developed outdoor three-in-one direct-plug products. Using this packaging method, the direct-plug LED display can achieve a smaller density without changing the production process, and is extremely competitive in price.
Xu Pei, manufacturing director of Shenzhen Jinhua Optical Technology Co., Ltd. (hereinafter referred to as Jinhua Optical Technology), revealed to reporters: "As we all know, direct-plug products originally adopted a three-lamp separate packaging structure of red, green, and blue, with each pixel having 6 lamp pins. Later, we began to consider whether we could reduce the lamp pins while giving the product the same display performance and weather resistance. Through simulation drawings, we found that the solution of packaging three chips together was initially feasible. OK. After more than a year of research, we completed the mold opening of the lamp bead bracket, the selection of the chip, and the final sample. After a long and arduous period of research and development, we continued to improve under the pressure of various doubts and criticisms, and conducted repeated testing and verification in mold opening, samples, and research and development. After half a year, the display performance and stability of the outdoor direct-plug three-in-one product finally met the requirements. "
According to Jinhuaguang Technology General Manager Guo Jianliang, the three-in-one direct plug is an upgraded product of current direct plug products. It does not change the packaging process of traditional direct plug lamps, but it makes a breakthrough in product structure and combination by packaging three RGB chips in one lamp and using four lamp pins. Compared with the traditional full-color display that requires three single lamps as one element point, now only one single lamp is needed to achieve the same effect, which greatly reduces production and material costs and makes the product highly competitive in price. At the same time, the outdoor direct plug three-in-one solves the dilemma of display performance and weather resistance. Guo Jianliang confidently told reporters: "On the one hand, innovation must improve performance, and on the other hand, it must also reduce customers' usage costs. If innovation cannot be converted into actual economic benefits, such innovation is meaningless."
Features and advantages of direct-plug three-in-one products
In recent years, Jinhuaguang Technology has continuously invested in R&D and innovation, achieving breakthroughs in the fields of LED packaging and LED display applications. The independently developed DIP-JH570 packaging process has been upgraded, and the LED display product line has been further improved. It has realized the configuration of multiple product specifications such as P6, P6.67, P6.944, P8, P8.33, P10, etc., meeting the different needs of customers and receiving good response in the market.
