Why Display Panel Repair Requires Lasers
In display panel manufacturing, laser repair is essential for boosting yield rates and controlling production costs:
Save Costs: Reclaims defective panels, preventing costly scrap and boosting yield.
Micron Precision: Ultra-fine laser beam targets microscopic shorts, bright spots, and dust with surgical accuracy.
Zero Damage: Non-contact processing with minimal heat leaves surrounding pixels completely unharmed.
Line-Speed Fast: Takes milliseconds per repair, perfectly matching high-speed automated production.
Bottom Line: Turns factory scrap into sellable yield in milliseconds.
TFT-LCD Laser Defect Repair
At CKD, we provide high-precision laser equipment for display panel processing, helping customers boost yield rates and lower costs through stable, reliable processes.
Delivers high-precision localized micro-processing for micron-level spot defects on TFT-LCD panels, including bright spots, short circuits, and foreign particles.
Key Features: Equipped with a high-magnification vision alignment system with dynamic, micron-level control over laser spot shape and size based on defect geometry.
Technical Advantages: Delivers precisely controlled energy with a minimal Heat-Affected Zone (HAZ), eliminating defects while leaving adjacent pixels and circuits undamaged.
Suitable For: TFT-LCD line spot defect repair | High-PPI panel micro-repair
Enables fast, targeted laser cutting and repair for continuous line defects occurring in TFT-LCD production, such as signal line shorts and bright lines.
Key Features: Supports real-time tracking for complex or irregular paths, featuring fast-galvo scanning to keep pace with high-speed production line rhythms.
Technical Advantages: Cuts target lines with extreme precision without damaging the underlying glass substrate or encapsulation layer, significantly reducing Tact Time per line.
Suitable For: Medium to large TFT-LCD panel lines | Automated in-line defect reduction
Designed for the critical LLO process in flexible OLED manufacturing, utilizing laser energy to induce photothermal decomposition of the Polyimide (PI) sacrifice layer, realizing damage-free separation of the flexible display from the glass carrier.
Key Features: Uses a high-uniformity beam homogenization optical system to guarantee consistent energy output across large processing areas.
Technical Advantages: Non-contact photolytic lift-off with zero mechanical stress or pulling, preventing panel bending, layer delamination, or thermal distortion for consistent output quality.
Suitable For: Flexible OLED production lines | Substrate lift-off for foldable displays & wearable electronics
