Manufacturing Workflow

Key Precision Steps Captured on the Production Line

Step 01
Cleanroom & LED Backlight Assembly
Assembled in Class-10,000 dust-free cleanrooms. Precise LED backlight strip mounting and panel pre-assembly guarantee uniform display brightness, zero dust spots, and longer panel lifespan.
Step 02
Precision Glass & Metal Frame Bonding
High-transmittance anti-glare tempered glass and slim aluminum bezels are bonded with high precision, ensuring structural rigidity and an edge-to-edge premium touch surface.
Step 03
In-House Mainboard & SOC Integration
High-performance Android / Windows SOC mainboards, power supply modules, and front I/O interface boards (HDMI, USB, Type-C, OPS slot) are mounted with shielded cable routing.
Step 04
40-Point Touch & Latency Validation
Every panel undergoes full-screen touch linearity calibration. Engineers test multi-point writing smoothness, corner touch precision, and response latency across 20+ draw grids.
Step 05
100% Full-Load 24-Hour Aging Test
Before packaging, 100% of finished screens run continuously for 24+ hours in elevated temperature chambers to eliminate early component failures and verify thermal stability.
Step 06
Export Packaging & Direct Container Shipping
Panels are sealed in ESD bags and drop-tested honeycomb cartons. Large orders are reinforced with flight cases or wooden crates and loaded into sea containers directly on-site.
