The past two years have marked the beginning of the layout of large-size LED conference all-in-one machines. Since last year, market demand has exploded, and large sizes have become a high ground for manufacturers. For the LED display industry market, the LED all-in-one machine has brought new increments. With the full application of large-size LED all-in-one machines in the industry, it will create a new round of LED display growth.
For this reason, the editor of the Digital Audiovisual Engineering Network has drawn up three topics about "LED all-in-one", and specially invited three companies in the industry, Unilumin Technology, Corrent, and Shijue Guangxu, to participate in research, express opinions and discussions to understand The latest progress in the development of LED all-in-one!
1. In the past two years, LED all-in-one is one of the hottest topics in the LED display industry. Because of the popularity of this product, many companies have converged on a battlefield. Why is this? What do you think is the advantage of Led all-in-ones compared with LCD all-in-ones?
Zhouming Technology: First of all, LCD and LED have their own advantages and disadvantages, and user evaluation is the most objective. From the perspective of product design and technical application level, the LED conference all-in-one is suitable for conference terminal displays of more than 100 inches. Its self-luminous working principle makes the LED conference all-in-one better than LCD conference panels in terms of brightness, gray scale and color performance. , Size splicing and scheme integration are flexible, and the screen linkage is strong. Unilumin conference all-in-one machine inherits genetic advantages in many aspects.
Corent: With the development of the industry, the small-pitch LED technology and technology used in the manufacturing of conference all-in-one machines have been relatively mature, and LED displays have also accelerated their penetration into commercial display and other fields. In the past two years, the main market for LED all-in-ones is the conference market, but traditional projectors in the conference market still occupy a monopoly position. Although LCD is increasing its application scale in the commercial display field, its expansion speed is not limited by the size and price of the flat panel. Not satisfactory.
In the traditional conference market, more projectors and LCD screens are used, but the projectors have relatively high requirements for indoor environment and light, which can easily create small dark rooms, and the conference will appear more depressing, and the LCD screen is only limited. In the market below 90 inches, compared with LCD all-in-ones, Led all-in-ones also have the advantages of large size, higher brightness, light and thin, easy to install, easy to maintain, display color performance, and high image quality; so in the past 2 years , The emergence of LED all-in-ones has ushered in a new situation in the conference market, which has doubled the market, and the new trend of sales growth in the LED display industry. At the same time, with the outbreak of the epidemic in 2020, the conference market will push the conference all-in-one to a climax. Mobile office, remote office, online education, etc. have accelerated and stimulated the development of this trend.
Shijue Guangxu: In the era of information technology, LED displays are like rising stars. With their absolute advantages such as high brightness, high definition, and arbitrary splicing, they have become the world's most watched information display technology after CRT, LCD, and 0LED. , The application market continues to expand, and is widely used in the field of large screens. The LED all-in-one machine is spliced by each LED display unit, which can easily achieve a large screen of 100 inches or more, without visual seams, which can meet multiple people's viewing; small spacing display, ultra-wide viewing angle, viewing from any angle from left to right, no Reflective and no color deviation. With excellent display effect, the picture is clearer and the color is more delicate. Moreover, the LED all-in-one machine is lighter and thinner, which is convenient to move, install and disassemble.
2. Due to the technical characteristics and the pain points of market demand, LED all-in-ones have room for imagination in the fields of enterprises, institutions, governments, and hospitals. What is your company's LED all-in-one machine's application positioning in the industry? What is its leading position and how is its price performance? At present, what is the maximum size of the corresponding product?
Zhouming Technology: We have always positioned itself in the full-scene all-in-one machine and solution in the conference market. As a commercial or even civilian product, we are in a leading position in the industry with many ease-of-use advantages such as convenient installation design, unique UI interaction, energy saving and high efficiency, and independent software development and application features. Based on the general environment of the epidemic and the fluctuation of raw materials in the upstream supply chain this year, our Unilumin maintains stable prices with large-scale standard products, mature and advanced manufacturing supplies, and technological innovation. In the long run, the price trend of LED conference all-in-ones is inevitable! At present, the largest size all-in-one can reach 217-inch 2K conference display applications.
Corrent: Corrent’s LED all-in-one concept and products came out relatively early in the industry, starting in 2015, and first defined "high density", "standardization", "internetization" and "user-level" as commercial display products. , The difference between LED all-in-one products and conventional special display products is divided. Corrent's LED all-in-one products have developed to the fourth generation; in fact, our products have been developed to the present in government and enterprise units, hospitals, education, exhibitions, There are developments in fields such as live broadcast, and our products are currently building a scene-based intelligent ecology. Not only LED all-in-one products, but also integrated solutions and services such as scene peripheral audio and video, and central control are being brought to customers. So we The product definition of Shangxian has added two more points from 2019: "scene" and "interactive experience".
At present, Corrent LED all-in-one products have many industry leaders in structure, function application, and scenario solutions. In terms of structure, the industry's first segmented splicing, foldable lifting, ultra-light and ultra-thin elevators can be easily transported and other features; In the application of functions, there are many special functions such as eye protection, energy saving, intelligent brightness adjustment, AI voice control, electronic whiteboard, etc.; in terms of scenes, Corrent has already started from the meeting scene to create a full range of scene-based solutions. Immediately, there will be party building scenes, live broadcast scenes, exhibition display scenes, smart theater scenes, and smart medical scenes that will be improved one after another to meet the needs of more customers. In terms of product positioning, we have always positioned the mid-to-high-end market, and established our own brand on the basis of ensuring product quality, stability, and user experience.
For the maximum size of the LED all-in-one machine, it is currently possible to seamlessly splice products with different pitches on the basis of 4K resolution, not only the previous 108”, 135”, 163”, and 216” single products, but within the 4K resolution range , Multiple units of this resolution can be seamlessly spliced and controlled together, and a maximum of four 216" products can be seamlessly spliced and displayed, so that it can be used in more larger scenes such as lecture halls, command centers, auditoriums, etc. .
Shijueguangxu: According to market matching analysis, Shijueguangxu's LED display all-in-one machine can be more used in the meeting rooms of government, enterprises and institutions. Shijue Guangxu LED display all-in-one is ultra-light and ultra-thin, saving space, controllable size, and perfect customization. Compared with similar products, Segère’s 110-inch LED all-in-one is lighter and thinner, and can achieve an average weight of 0.7 kg per inch of display size, and the product thickness is only 29.5 mm. Using the components that meet the highest quality standards, the display effect is better, the service life is longer, and the cost performance is higher. Sightseeing LED conference all-in-one machine has a variety of sizes to choose from. The recommended sizes are 2.4x1.35m, 3x1.68m and 3.6x2.02m. The display resolution can reach 2K and 4K.
3. From the beginning of 2020 to now, you can see LED display companies get together to launch new LED all-in-one products, focusing on the conference market. From the general small pitch to Mini LED to Micro LED, because of the different technologies used, the selling points of each product are different. What technical route does your company's LED all-in-one machine take, what advantages does it have, and how small the spacing can be?
Zhouming Technology: We are not limited to a certain technical route, but provide more suitable products based on the user's value proposition and the advantages of different pixel packaging. Our application in MinLED products has matured and been marketed. In terms of spacing, we can mass produce conference screens with a 0.9mm pitch. The 0.7mm pitch is already in the mass trial production stage, and it will take a long way for users to popularize.
Corrent: The current route taken by Corrent is mini 4-in-1+GOB or SMD+GOB and other technical solutions. In terms of spacing, it also achieves mass production with the smallest P0.9 spacing, which is mainly based on the current customer needs and industry environment. Product technical solutions, product maintainability, product cost estimation, product practicability and other aspects have been comprehensively considered to locate the technical route. Of course, we have been investing in research and development for COB, flip-chip COB, P0.7, etc. Verification, if the customer needs it right away, we can also get it right away.
Shijue Guangxu: Shijue's small-pitch product QM series adopts COB packaging micro-display technology maturely, without seams, which can make the screen have more extraordinary color expression. Effectively reduce light radiation, suppress moiré, anti-glare, and the near-screen viewing experience is almost perfect, providing an excellent conference display solution for government, enterprise, education, medical and other applications. The minimum spacing of QM-COB series can be 0.9mm.
To sum up: Although the technologies of each company are different, the small-pitch LEDs of the three companies can now achieve a pitch of 0.9mm. Last year, under the catalysis of the epidemic, the demand for remote office and cloud video conferencing increased sharply, which accelerated the development process of LED all-in-ones in meeting scenarios, and further emerged for all-in-ones that are more suitable for meeting scenarios. Today, with the increasing number of new entrants from all parties, such as home appliance companies, LCD interactive flat panel companies, splicing screen companies, etc., the LED all-in-one market will gradually become a new battlefield for companies to grab.
