At present, Mini LED backlight display technology is developing rapidly, lighting up a variety of application scenarios:
Consumer Electronics:
According to incomplete statistics, nearly 50 Mini LED backlight TV and MNT products have been launched this year, and they are developing in two directions: "high-end" and "high cost performance".
Vehicle display:
The development of new energy smart vehicles is on the rise, and many well-known car manufacturers such as General Motors, Ford, BMW, and Mercedes-Benz are promoting Mini LED in-vehicle displays.
VR display:
Due to the excellent brightness and high contrast ratio, well-known VR manufacturers such as Varjo, Meta, and Skyworth VR are also gradually launching new VR products equipped with Mini LED backlight technology.
In the face of increasingly widening application fields, if Mini LED backlight products want to accelerate market penetration, a balance must be struck between cost and technology, among which the choice of Mini LED backlight packaging technology is particularly critical. In this context, POB and COB are always on the cusp of the game of Mini LED backlight technology due to their own advantages and disadvantages.
On November 24, at the 2022 Gaogong LED Display Annual Conference and Gaogong Golden Globe Awards Ceremony, Liu Fabo, Chief Engineer of the R&D Department of Nationstar Optoelectronics Components Division, focused on POB and COB packaging technologies, and shared the latest Mini LED backlight technology with the guests on site. solutions and development trends.
Cost + process Mini POB technology
The "best choice" for industrialization
Mini POB is one of the Mini LED backlight technology solutions promoted by NATIONSTAR. The module business department has been deeply involved in technology and pioneered innovations. Through the unique light source structure design, the Mini POB solution of Nationstar Optoelectronics has achieved light output within a super-large viewing angle range, which can meet the needs of light and thin modules, high image quality and low cost; at the same time, the solution is in Under the same area of the backlight module, the number of lamp beads required is greatly reduced, the production yield is high, the mass production is strong, and the price competitiveness is outstanding.
In terms of application fields, NATIONSTAR Mini POB has covered various large-size TVs such as 55 inches, 65 inches, 75 inches, and 86 inches, monitors such as 27 inches, 31.5 inches, 34 inches, and 49 inches, and vehicle backlight displays. There are three options for the driving mode: "light driver separation", "PM type light driver integration" and "AM-Micro IC type light driver integration". Customized technical solutions can be provided according to customer needs.
Performance + Effect Mini COB Technology
"Potential stocks" for all-field applications
Different from Mini POB, the Mini COB backlight solution belongs to the chip-level mounting solution, which proposes higher technology for key processes such as printing, die bonding, rework and packaging, as well as materials and indoor video wall equipment such as PCB, chips, packaging glue, fixtures and equipment. Require.
At present, the Component Business Department has given full play to its own advantages and actively promoted the development of NATIONSTAR Mini COB in the direction of high brightness, high consistency, high reliability and high cost performance: it adopts full array of high-efficiency chips + package lightening treatment to solve the problem of insufficient screen brightness Problems: Through special die-bonding algorithm combined with packaging optimization, the consistency of the light color of each light source in the array is realized; the experiment of high temperature, high humidity and cold punching ensures the high reliability of the product; based on packaging optical optimization, the light mixing performance is improved, and the realization of Similarly, the backlight module pulls down a large LED pitch to reduce the number of required light source points, so as to achieve the goal of optimizing the cost of the light source.
In terms of application fields, NATIONSTAR Mini COB can be applied to TVs, monitors, notebook computers, and PADs, and its OD can reach above 0mm. There are three options for the driving mode: "light driver separation", "PM type light driver integration" and "AM-Micro IC type light driver integration", all of which are packaged through an optical lens, and customized technical solutions can be provided according to customer needs .
The two-wheel drive of "innovative technology + high-quality products" has won the market. At present, NATIONSTAR has established strategic partnerships with many internationally renowned manufacturers for its Mini POB and Mini COB backlight products. "Quality improvement and cost reduction + production capacity expansion" dual-engine attack leads the development. With the put into use of the advanced production line of Nationstar Optoelectronics, it will further improve the mass production yield of products, reduce costs, and help the company respond to market demand more quickly. The commercialization of LED backlight has injected strong impetus.
