#From indoor to outdoor, COB LEDs drive into a new track

What does it mean to launch the first outdoor COB product? The traditional LED direct display market is divided into two distinct sectors: indoor and outdoor. Each supports almost half of the market. The move of COB technology to the outdoors first means a huge increase in the scale of potential applications.

According to data from the China Research Institute of Pricewaterhouse-based Industries, the market size of my country's LED display screens in the first half of 2023 will be approximately 24.2 billion yuan, of which the market size of small-pitch LED displays mainly for indoor areas will be approximately 9.1 billion yuan. It can be seen that the outdoor and indoor LED screen markets each account for almost half of the sky.

On the other hand, according to data from Intelligent Research Consulting, the market size of China's outdoor electronic screen advertising industry exceeded 20 billion yuan in 2019 and exceeded 30 billion yuan in 2022. It is expected to exceed 38 billion yuan in 2023-the rapidly growing outdoor advertising demand is one of the main monetization directions for outdoor LED screens. Benefiting from the in-depth commercialization of 5G and the support of creative technology forms such as naked-eye 3D, corner 3D, curved special effects and night scenes, the value of LED outdoor applications has been continuously enhanced.

Therefore, COB products actually face dual opportunities in the outdoor market: upgrading existing experience and incremental market expansion. Among them, COB products will bring new experiences to outdoor applications, which will be their main competitive advantage.

In this regard, Zhouming Technology pointed out that one of the main progress points of outdoor advertising and display systems in the 5G and future 5.5G/6G era is the development of content towards high-definition, ultra-high definition, 3D and holographic display effects. Higher display effect requirements will inevitably require better screen technical support. This not only includes the optimization of traditional technical parameters such as color, brightness, and contrast, but also includes the improvement of resolution density, the optimization of viewing angle, and the overcoming of grainization of visual pixels.

"The traditional understanding of COB is that it can reduce the spacing of LEDs; but at a larger spacing, COB technology can also bring about a revolution in the visual experience. Industry analysis pointed out that Zhouming Outdoor COB's 0 breakthrough is to break this inherent thinking and allow COB's technical advantages to shine in larger application scenarios.

#From ultra-micro spacing to the outdoor market, COB has stronger technical advantages
