Ultra HD Indoor LED Small Pitch Screen - P0.9/P1.2/P1.5 - Seamless Video Wall for Control Rooms
XM-II is a small-pitch LED display designed for high-end indoor scenes. It adopts advanced macro-pitch patch technology to achieve an ultra-small pixel pitch of P1.2-P1.8. The picture is delicate and has no graininess. It is perfectly suitable for command and control, conference halls, radio and television broadcasting and other places with strict requirements on picture quality.
Production Process
Ultra-high density pixels
The COB small-pitch LED screen uses advanced chip direct packaging technology (Chip on Board), which integrates LED wafers directly on the PCB board, greatly reducing the pixel pitch (P0.9-P1.8) and achieving a pixel density of one million per square meter. Compared with traditional SMD packaging, there is no bracket shading and reflection problems, the display image is smoother and more delicate, and there is no graininess even when viewed at close range, which is suitable for scenes with strict requirements on image quality, such as high-end conference rooms and command centers.
Excellent reliability and protection performance, service life up to 100,000 hours
COB technology protects LED chips through overall epoxy resin encapsulation, with advantages such as moisture-proof, dust-proof, anti-static, and anti-collision, and the protection level is above IP54. The design without exposed solder joints avoids the risk of cold soldering and falling off, and the failure rate is reduced by 90% compared with SMD. With low brightness and high gray technology, the screen can still maintain color consistency after long-term use. The life span exceeds 10 years when used for an average of 12 hours a day, greatly reducing maintenance costs.
Intelligent front maintenance
Modular front maintenance design supports single-box quick disassembly without reserving rear space. The thickness of the entire screen is controlled within 80mm, which can be installed on the wall or seamlessly integrated with the decoration. The fanless heat dissipation architecture is combined with an efficient aluminum substrate, and the working noise is <20dB, which is particularly suitable for quiet environments such as conference rooms and studios. It supports automatic brightness adjustment and remote monitoring, and operates stably 24 hours a day, 7 days a week.
Low brightness and high grayscale performance
Using 16-bit high-precision driver IC, it can still achieve 65536-level grayscale control at low brightness of 100nit, solving the problem of color block discontinuity in traditional LED display in dark fields. With the HDR10+ algorithm, black is purer and bright parts are not overexposed, perfectly presenting medical images, starry sky photography and other content with high requirements for dark levels, meeting high-end needs such as professional film and television post-production and museum exhibitions.
180° ultra-wide viewing angle and cinema-level color gamut coverage
The COB packaged light source has no directional restrictions, and the horizontal and vertical viewing angles are both 178°, and there is no color deviation when viewed from the side. Supports DCI-P3 98% wide color gamut, with point-by-point correction technology, color difference ΔE<2, reaching broadcast-level standards. Whether it is a curved screen or a special-shaped installation, it can ensure true color at any angle, suitable for multi-viewing scenes such as large stages and brand showrooms.
