Foldable COB LED All-in-One Machine: Redefining Display Flexibility and Image Quality Limits

In today's era of increasingly diverse digital display needs, the pain points of traditional LED screens—such as bulkiness and cumbersome deployment—have become more prominent. The emergence of the foldable COB LED all-in-one machine perfectly combines the image quality advantages of COB packaging technology with the spatial flexibility of a foldable structure. It has become a new favorite in scenarios such as business meetings and exhibition displays, completely breaking the inherent perception of "fixation" for display devices.

The core competitiveness of this device stems from the revolutionary breakthrough of COB packaging technology. Different from traditional SMD packaging, COB (Chip-on-Board) technology directly solders bare LED chips onto a PCB board and encapsulates them with epoxy resin to form a surface light source, eliminating the packaging process for individual lamp beads. This design allows the screen's pixel pitch to be as low as 1.5625mm or less. Combined with a resolution of 1920x1080 and above, the image details reach a "microscope-level" fineness. At the same time, the surface light source feature completely eliminates the glare problem of traditional point light sources. With an 110% NTSC wide color gamut and a high contrast ratio of 5000:1, the color transition is natural and realistic, and visual fatigue is less likely to occur even after long-term viewing.

The innovative design of the foldable structure solves the transportation and deployment problems of large-size screens. Taking the mainstream 135-inch model as an example, it adopts 180° backward folding technology. After folding, its height can be controlled within 2.1 meters, allowing it to enter elevators directly. A single device can be flexibly transported using a mechanical mobile cart. Compared with the traditional LED screen, which needs to be disassembled into multiple modules and installed by multiple people, it achieves an efficient experience of "quick unpacking in 2 minutes and complete deployment in 1 hour". In scenarios such as outdoor music festivals and temporary exhibitions, the efficiency is increased by up to 5 times. The die-cast aluminum ultra-light cabinet and IP30+ protection level further ensure structural stability during frequent folding, and its anti-collision and dust-proof performance is significantly better than that of traditional equipment.

Intelligent integration is another major highlight. Most devices are equipped with dual Android and Windows systems. The 4G memory + 32G storage meets the needs of multi-tasking. The built-in wireless screen projection function supports four-screen synchronous display across multiple platforms. The rich interface configuration includes HDMI, USB 3.0, RJ45, etc., which can seamlessly connect with conference whiteboards, video conferencing software and other devices, breaking the barrier of information transmission. In terms of energy consumption control, the excellent heat dissipation performance of COB technology reduces the average power consumption to as low as 800W/㎡, which is more than 30% lower than that of traditional screens. Combined with the constant temperature fanless design, it achieves the dual goals of silent operation and green energy saving.
