Intelligent All-in-one LED Display’s Development and Opportunities

 As a new display technology that has emerged in recent years, the fine-pitch LED display has continued to heat up the market, and it has also shown a trend of rapid growth for several consecutive years. Since the pixel pitch of LED display screens crossed the P3 boundary in 2012 and entered the era of P2.5mm, the fine pitch of indoor LEDs has been like a broken bamboo, occupying half of the country in the field of large-screen splicing. Compared with traditional projection fusion, LCD splicing, DLP splicing and other display technologies, the fine pitch of LEDs has gained the market’s hard-core advantages such as independent light emission, high brightness, high color gamut, seamless splicing, unlimited size, and long life. It is generally recognized as the first choice for high-end application scenarios. According to a third-party report, from 2015 to 2020, the LED fine pitch will continue to maintain a growth rate of more than 30%. As of 2020, the domestic LED fine pitch product market has reached 12 billion yuan.

The rise of Intelligent all-in-one LED display

After several years of rapid development, LED fine pitch display has been widely used in various industries, but it is still limited to the professional display market. The main application scenarios are still command centers, monitoring centers and other scenarios. Its application has the characteristics of long project cycle, complex system architecture, and high requirements for users' professional capabilities. It may take half a year to a year or even longer for a project from the beginning of the requirements to the final landing. At the same time, the characteristics of project-based customization determine that each project is different and does not have batch replication. How to break through the restrictions of product form, transform from customized engineering projects to standardized products, penetrate from professional display market to commercial display market, and even consumer market, is a question that the LED fine-pitch industry has been thinking about, so the LED smart all-in-one machine came into being. .

Different from the project-based, customized, and system-integrated features of LED fine-pitch engineering screens, the LED intelligent all-in-one machine is developing in the direction of standardization, productization, high integration, and intelligent interaction, creating a standard size, standard resolution, Product forms with standard functions and standard prices are quickly introduced to the market through batch copying, which promotes the rapid penetration of LED fine pitches into conference rooms, multimedia classrooms and other scenes.

Under the catalysis of the new crown epidemic in 2020, LCD conference all-in-one products have also grown explosively against the trend. In 2020, the annual sales of LCD conference all-in-ones will increase by more than 36% year-on-year to close to 400,000 units. The conference shows that the market is a broader market. According to research, there are more than 60 million meeting rooms in the world, and more than 20 million meeting rooms in China. There are close to 1 million large and medium-sized meeting rooms suitable for the installation of LED smart all-in-ones. It is a market with hundreds of billions of capacity, full of imagination.

Advantages of LED smart all-in-one

Before the emergence of the LED smart all-in-one machine, the display screens in the conference room were mainly projectors, LCD liquid crystal all-in-one machines, and LCD splicing screens. Compared with these types of displays, the LED smart all-in-one has the obvious advantages of larger size, better display effect, highly integrated functions, and more convenient use.

1. Larger size

At present, the mainstream size of traditional LCD liquid crystal all-in-one is 65, 75, 86 inches, and the conventional size of commercial projectors is only 100 to 120 inches. According to a survey by the American Society of Motion Picture and Television Engineers, a viewing angle of 30°~40° can give people the best visual experience. The best screen width is 3 meters, and the converted screen size is 138 inches, while the best screen size for a larger conference room of 80 to 120 square meters is about 165 inches.

From another dimension, based on the physiological resolution of the human eye, it is generally believed that the ultimate resolution of the human eye is 1 arc minute (1/60 of an angle of 1 degree). 1 arc minute = 1/60 degree = 0.000291 radians, corresponding to a viewing distance of 5 meters away, the minimum point distance that the human eye can distinguish is about 1.5mm, when displaying the most conventional full HD image (1920*1080), it is required The screen size is 130 inches, which means that when the screen size is less than 130 inches, the human eye can no longer clearly distinguish the stroke boundaries of the fine text on the screen.

From the above two dimensions, it can be seen that the best display size for medium and large conference rooms is 138 inches to 165 inches, which has completely exceeded the upper limit of the LCD LCD all-in-one size. This is exactly the golden size of the LED smart all-in-one machine, and each company has launched products of similar size.

2. The display effect is better

Due to the principle of autonomous light emission of the LED display, its brightness, contrast, and color gamut range far exceed other conventional display technologies, and it has incomparable advantages in terms of display effects. Especially compared with the dim picture of traditional commercial projectors, the LED smart all-in-one has a bright picture, saturated colors, and will not be fatigued for long-term viewing. It also avoids the inconvenience of turning off the lights and closing the windows before the meeting. As shown in the comparison in Table 1 below, the LED smart all-in-one machine is leading the way in terms of image display parameters.

3. Function integration, easy to use

Compared with pure display conference room displays such as commercial projectors and LCD splicing, LED smart all-in-ones are more integrated and more powerful. The usual LED smart all-in-one machine integrates functions such as Android system, power on/off control, display screen, power amplifier audio, source access, wireless screen projection, etc. The user operation is simple, and complicated system connections are also omitted. The LEDHUB smart conference system launched by Ledman Optoelectronics has built-in Android and Windows dual systems and a high-precision large-size infrared touch screen, creating a smooth experience of seamless switching between dual systems and dual touches. It is these inherent advantages of the LED intelligent all-in-one machine that make this product develop rapidly as soon as it is launched.

According to a third-party report, as of the end of 2020, the market size of LED smart all-in-ones has exceeded 600 million, and the growth rate has increased by 160% year-on-year compared with 2019.
