As a world-renowned power electronics company, Delta Electronics has always followed the corporate mission of “Environmental Protection, Energy Conservation, and Love for the Planetâ€. In the emerging green environmental protection industry, focusing on the R&D and production of LED display, its quality and reputation also ranks among the world leaders. Today, we have the honor to interview Mr. Fu Jie, General Manager of Delta's Electronic Video Business Unit, to explain the current status and development direction of the LED display industry, and also provide guiding suggestions for customer purchase.
Based on technology, comprehensive experience, creating quality
"For LED display screens, Delta is not the first manufacturer to produce such a result. It is inseparable from Delta's strong design capabilities and production methods." Mr. Fu Jie said, "Delta Electronics is engaged in video display. For example, the R&D and production of the industry has more than 15 years of experience, and there are many advantages in controlling the color and quality of the picture. Meanwhile, the senior technical consultant of Delta Electronics has 30 years of experience in adjusting the screen display equipment. It can integrate the experience of the original large-screen display system, and can be extended to the application of display technologies such as LED and LCD, and provide more targeted products and solutions according to different customer needs.
Delta attaches great importance to the solid technical foundation. From the customer's point of view, it will consider the application needs of customers at the beginning of product development, and integrate the technical experience of Delta's existing products, such as DLP large-screen display system. LED light source, etc., research and development and production of LED splicing display equipment, and finally applied to indoor and outdoor advertising, stage and many other occasions.
Focusing on the LED splicing display screen, its biggest challenge lies in outdoor use. How to accept the wind and rain for a long time, the harsh environment with high and low temperature alternate is a problem that many LED manufacturers are troubled by. Delta Electronics takes the interests of its customers first, and all displays, including outdoor applications, have undergone rigorous and demanding testing and certification. In particular, the IP65 protection level is rare in the industry and can meet the needs of outdoor applications. Delta's outdoor LED large screen has been used as a full-time outdoor display during the Starlight Tour and the Global Astronomical Year. It has undergone a baptism of heavy rain, and its display effect has hardly been affected. It perfectly displays the colorful colors and the detailed and complete picture. .
Outdoor display wins advantage
As the world's largest supplier of switching power supplies, Delta's LED display products have a power efficiency of more than 90%, which not only saves energy, but also reduces system operating costs. At the same time, the PFC power supply is installed, and the 64-segment brightness control function is added, which can automatically adjust the brightness of the whole screen according to the change of ambient brightness, thereby achieving energy saving purposes. The improvement of power efficiency also contributes to heat dissipation of the product, thereby better ensuring system security.
Mr. Fu Jie pointed out that the reason why Delta's LED outdoor display can achieve the protection level of IP65 before and after is that it adopts integrated aluminum alloy packaging technology. In theory, there is no air convection inside and outside the box. Delta fixes the waterproof rubber ring with screws to minimize the gap to ensure isolation inside and outside the box. At the Shenzhen Photonics Exhibition in 2009, the experiment of rainwater spraying during the lighting process of Delta's LED display products impressed many exhibitors. Mr. Fu Jie said, “Delta LED display products are waterproofed from aluminum alloy cabinet structure to DVI line head and power supply to ensure its outdoor application.â€
In addition, the consistency of LED display products is difficult to guarantee and is a common problem in the industry. Due to the problem of the production process, even the same batch of LED light sources cannot guarantee the brightness and color temperature of the same batch. Mr. Fu Jie said, “Delta will perform point-by-point correction before each LED module leaves the factory to ensure the best display performance.†Delta introduced point-by-point correction optical equipment to shoot LED modules in the dark room. The data is synchronously transmitted to the control computer, and each pixel is analyzed and calculated by the application software, and the data is obtained, corrected, and transmitted back to the unit on the module, thereby ensuring that the brightness and color temperature of each point are consistent.
The development direction of LED display
According to the scope of application, LED display products can be roughly divided into three categories: pure outdoor, semi-outdoor and pure indoors. Different applications have different development directions. At present, pure outdoor display, due to the relatively large relative area, such as the stadium display, etc., generally uses a separate package. Because of its large area and long viewing distance, the distance between the dots is relatively large, ranging from 15mm to 25mm, which can be very perfect.
In the past, most of the semi-outdoor display products used in-line packaging, but nowadays more and more SMD RGB three-in-one surface mount integrated application direction. There are two reasons: First, LED display products using SMD package can achieve high brightness and high efficiency, and now have more than 1W lumens; second, semi-outdoor display viewing distance is relatively close, so the requirements for imaging Very high, LED display products packaged with SMD surface mounts are more expressive.
Pure indoor display, naturally with exquisite and delicate performance to win, Delta's current point design in pure household display is 6mm. At the same time, indoor LED display with 4mm dot pitch is also under development. In the future, according to the continuous improvement of LED technology, Mr. Fu Jie said, “Delta Electronics will further develop indoor LED display products with smaller spacing.â€
Mr. Fu said that Delta has a complete product line including DLP, LCD, LED and other display systems, so in the application of higher demand, if you need more delicate image quality, clearer display effect, Delta Alternatives will also be introduced depending on the occasion and the needs of the customer, such as LCD or DLP projectors with fine image quality. Delta will use different technologies according to the occasion, and design different products for customers to choose.
Delta LED display marketing strategy
In the research and development and production of LED display products, Delta Electronics adheres to the corporate mission of “energy saving, environmental protection and love of the earth†and pursues high quality performance. At the beginning of product development, Delta Electronics integrates its superior resources such as power efficiency and R&D capabilities in the field of video display, and utilizes its supply chain and production capacity in Asia through cost control and production process improvement. Accelerate the deep penetration of Delta's LED display products in China and provide more cost-effective products for domestic customers. This is the current positioning of Delta's products.
For consumers, both quality and price will have an impact when they choose a product. Nowadays, in the LED display market, there are also a small number of companies that cut corners and cut down on materials, and inferior products are manufactured with inferior raw materials. If customers are blindly guided by cost, regardless of product quality, they will easily lead to greater losses. In fact, as far as the market is concerned, many customers who buy LED displays care more about the added value brought by the products. For example, advertisers and stage lighting and sound controllers are profitable. Under such circumstances, product quality, maintenance costs, and service life have become more of a concern for customers. Therefore, high-quality, highly reliable LED display products have become the choice of most customers.
Mr. Fu Jie said that 2010 is the first year of Delta brand. For the LED display screen, Delta will follow the brand marketing strategy, and provide customers with perfect and convenient technical services while selling products. Through in-depth understanding of customer needs, it provides targeted installation, inspection, maintenance and other services. In the domestic market sales and service, Delta Electronics' subsidiary, Zhongda Dentsu, has been cultivating for nearly 20 years, and has 35 branches throughout the country. While ensuring spare parts in various parts, it can also reduce service response time. To the shortest.
