LED display industry market analysis

LED display industry introduction

LED is a commonly used light-emitting device, through the combination of electrons and holes to release energy luminescence, can efficiently convert electrical energy into light energy, with high energy efficiency, strong monochromaticity, small size, long life and other advantages, is widely used in display, lighting and other scenes.

Before the development of LED display technology, the mainstream display technology in the market was LCD and DLP. Since the earliest popularization of single and double color LED display, LED display technology in the design, manufacturing, packaging technology continuous iteration driven, has gone through single and double color LED display, full-color LED display and based on smaller size light-emitting chip small-pitch LED display, Mini LED and Micro LED a total of 5 technical stages, downstream application scenarios have also expanded from outdoor advertising screens, door screens to indoor super large and ultra-wide displays, cinemas, TV, traffic and other scenarios.

?Industry market size

With the development of China's national economy and the upgrading of consumption structure, the proportion of the tertiary industry in the national economy has increased year by year, and the consumption expenditure of the cultural and sports industry has been increasing, which directly drives the demand for LED display in cultural and sports industries, and then drives the demand for LED display control and video processing systems.

With the development of LED material technology, the LED display industry has gradually incubated new LED display products such as Mini/Micro LED display, making the application scenarios of LED display expand from outdoor to indoor and consumer electronics. In the future, with the technical development and cost reduction of Mini/Micro LED display, the LED display market scale will continue to expand. In addition, as domestic enterprises have made major breakthroughs in epitaxial wafer materials, chip research and development, packaging design, application technology and other aspects, China's LED display manufacturers have also risen rapidly. The market size of China's LED display industry increased from 24.1 billion yuan in 2012 to 57.6 billion yuan in 2018. Under the background of the outbreak of the new crown epidemic in early 2020, the domestic LED display market size in 2020 decreased from 65.9 billion yuan in 2019 to 53.2 billion yuan. In 2021, the domestic LED display market will reach 57.6 billion yuan. It is expected that the market size will continue to grow to 82.5 billion yuan from 2021 to 2025.

Since the direct downstream of the video image display control industry is dominated by LED, LCD and other display manufacturers, therefore, LED display control and video processing system and LED display industry scale show a positive correlation, with the increase of LED display applications and the popularity of small pitch LED display, video image display control industry scale will maintain growth.

?Industry trends

1. The progress of chip technology and video image technology promotes the development of display control technology

The development of chip technology directly promotes the development of the industry in two aspects: first, the development of LED chip technology promotes the increasing pixel density of the display screen, the cost is getting lower and lower, and the small-pitch LED and Mini LED gradually enter the commercial market, and the application scenarios are constantly enriched; Second, the chip manufacturing process continues to improve, the process is getting smaller and smaller, the processing power of the chip is enhanced, the power consumption is reduced, and the size is reduced, and the performance and design of the video image display control system are enough to meet the needs of various professional, personalized, complex and refined application scenarios. Video image technology has experienced the development process of standard definition, high definition to 4K ultra high definition, and 8K ultra high definition. The technical advantages of ultra-high definition mainly lie in the greatly improved clarity, wide field of view and color gamut, high frequency and three-dimensional stereo. Its technology greatly improves the resolution, luminance color, frame rate, chromaticity, channel, sample rate and other indicators, doubling the amount of audio and video data, bringing a clearer, more realistic and immersive picture experience. The advancement of video image technology requires that display control is no longer simply transmitting the video signal that needs to be played to the display medium, but more deeply combining video processing technology and remote communication technology to build a more powerful video image display system for users.

2. Video processing equipment and transmitting equipment are gradually integrated

The display quality of video is not only closely related to the parameters of LED display, but also closely related to the optimization processing and transmission process of video information sources. In recent years, with the continuous improvement of people's requirements for the clarity and contrast of the display screen, as well as the continuous development of video processing and other related technologies, the way to improve the display quality has not only been limited to the update and iteration of the display, but also by reducing the distortion of the video signal in the transmission process and optimizing the video quality through processing technology to achieve the improvement of display quality. At present, equipment integration has become one of the main development trends of LED display control system, video processing equipment and transmitting equipment integrated solution can directly transmit signals to the receiving card through the video processing equipment, solve the existing video processing equipment and the transmission equipment incompatibility situation, reduce the transmission of video signals, reduce the possibility of distortion of video signals in the transmission process, while reducing replacement costs and hardware adaptation caused by failure rate.

3. The core position of video processing equipment will be further improved

The application field of the display screen continues to expand, inseparable from the support of video processing technology, mainly reflected in the user's requirements for the display effect continues to increase, 3D, HDR, 4K/8K ultra-high definition, AR/VR and other technologies not only require the display to support and adapt, but also require video processing equipment to have corresponding processing capabilities. Professional video processing equipment is the core component of application scenarios, and its core status will be further enhanced in the future with the diversification, complexity and specialization of application scenarios.

On the one hand, in some scenarios, the information that can be displayed by a single display screen can no longer meet the needs, and multiple different video sources need to be displayed on a large screen or multiple screens at the same time, and functions such as seamless stitching, free scaling, and arbitrary switching of each video signal can be realized. For example, in scenarios such as command and dispatch and remote meetings, you need to switch between video signals from different perspectives, different personnel, and different locations. Another example is the complex performing arts stageIn order to enhance the sense of layering and three-dimensionality, the background is usually composed of multiple movable, irregularly shaped, staggered LED displays, which not only need to coordinate and synchronize the display effect of the entire stage background, but also need to skillfully distribute the video signal to each display. On the other hand, providing more video information means that it is necessary to timely and efficiently process and transmit high-definition and even ultra-high-definition video, and traditional computers are limited by hardware architecture and software systems, which have natural shortcomings compared with professional video processing equipment. For example, with the popularization and development of 5G+8K technology, the processing and playback applications of ultra-high-definition video are gradually increasing, and professional video processing equipment can realize video signal acquisition in multiple formats, up to dozens of picture mixed displays, ultra-high-definition video quality improvement, conversion of different resolution formats, low-latency processing and other functions.

4. The integration of display control and communication technology continues to deepen

Video processing equipment is mainly used in celebrations, competitive events, conference activities, exhibitions, monitoring and scheduling, TV broadcasting, performing arts stage, commercial advertising, virtual shooting, information release, creative display, smart city and other fields, and some fields have high requirements for real-time image transmission. With the gradual commercialization of 5G, denser ultra-high-speed network coverage supports more efficient information transmission, ultra-high reliability and low-latency communication, helping to expand service applications that require both speed and stability. Under the trend of "Internet of Everything", various networking devices will increase rapidly, and new business models and new applications will have the opportunity to accelerate their development and bring more diversified and extensive display applications. With the promotion of 5G technology, the application scenarios of commercial display and smart home will also be expanded, and smart transportation, smart medical care, smart education, etc. will give birth to more applications and equipment technology upgrades, thereby promoting the rapid development of the video image display control industry.
