In the current surge in demand for ultra-high-definition displays, the XSTrong COB series displays, with the core technology of chip-on-board packaging, break the traditional SMD screen technology barriers, redefine high-end display standards, and bring revolutionary visual experiences to professional scenarios. COB technology eliminates the independent LED chip holder and integrates LED bare chips directly into PCB substrate, achieving mass production of P0.4-P0.9 ultra-micro pitch, pixel density 3 to 5 times that of traditional SMD screens. The screen surface is smooth like a mirror, upgrading from a "point light source" to a "surface light source". The ultra-high contrast ratio of 20000:1 makes the black field deep and pure, and with a 180 ° ultra-wide viewing angle, it completely eliminates graininess, glare, and moiré patterns. The text is sharp and clear, the picture is delicate and realistic, and the 4K/8K ultra-high-definition seamless presentation. Military-grade reliable, durable, and stable, using a fully inverted non-welding process to eliminate the hidden dangers of virtual welding and wire breakage from the physical level. The dead light rate is less than 5ppm, only one-tenth of traditional SMD screens. The integrated epoxy resin package achieves IP65 dust and water resistance, scratch resistance, moisture resistance, and anti-static, and can be cleaned directly with a wet cloth. The heat dissipation path is shortened by 50%, the junction temperature is significantly reduced, the lifespan of 100,000 hours is ultra-long, and the stable operation is 7 x 24 hours, greatly reducing maintenance costs. It is highly efficient and energy-saving, versatile in various scenarios, and equipped with co-anion energy-saving technology, which saves 40% energy compared to traditional products, with low consumption and low temperature rise, in line with the concept of green and low-carbon. Ultra-light and thin die-cast aluminum box, flatness ≤0.1mm, seamless splicing, suitable for close-range and high-demand scenes such as command centers, high-end conference rooms, museum exhibitions, and XR virtual shooting. XSTrong COB is ideal for high-end displays with hardcore technology and fine picture quality empowerment multi-scenes.
