Television Display Screen Production line
Differentiated technology application
- Adaptive vacuum suction cups (compatible with curvature radii R1500-R3000mm)
- Stress relief annealing furnace (temperature uniformity ±0.5℃)
- Massive transfer equipment (transfers 50,000 LED chips per hour)
- Micron-level phosphor film spraying (thickness control ±1μm)
smart calibration system
Color calibration station:
• Spectrophotometer automatic detection (ΔE < 1.5)
• AI automatic compensation for Gamma values (256-level grayscale correction)
• Dynamic performance testing:
• Verification of 240Hz refresh rate (high-speed camera captures motion blur)
• Detection of HDR peak brightness (2000 nits qualification test)
Typical assembly process
example of a 55-inch OLED TV
Front-end process
• Glass substrate cleaning → Organic light-emitting layer vapor deposition (vacuum level 10⁻⁶ Pa)
Mid-process assembly
• Flexible PCB laser drilling → Driver IC flip chip bonding (accuracy 2 μm)
• Polarizer automatic attachment (angle deviation < 0.1°)
Back-end final assembly
• Frame nano-injection molding (mold temperature control ±0.3°C)
• Smart audio module acoustic tuning (automatic frequency response curve matching)
Final inspection station
• Defect detection (darkroom environment at 5 cd/m²)
• Touchscreen multi-point touch testing (simultaneous recognition of 20 points)
