Hardening Technology for Cover Plates and Screens: CNK Display’s LCD Factory Ensures Screen Durability


In the display‑device sector, hardening treatments for cover glass and display panels are critical steps for enhancing product durability. As a specialized LCD manufacturer, CNK employs chemical tempering as its core process. This technology leverages a potassium–sodium ion‑exchange reaction to create a dense surface layer, achieving a 6H hardness rating (no damage observed in the 6H pencil‑scratch test). This solution is well suited for medical, automotive, and industrial applications, effectively protecting TFT LCDs, graphic LCDs, and other screen types from scratches while ensuring long‑term reliability.

Precision Chemical Tempering Process for TFT LCD Displays
CNK’s automated production line is specifically designed for multi‑screen‑optimized chemical tempering, covering both graphic LCD and TFT LCD displays. By precisely controlling ion‑exchange parameters, the facility ensures the formation of a uniform stress layer, significantly enhancing scratch resistance without compromising light transmittance. As a trusted LCD display manufacturer, CNK seamlessly integrates its tempering process with display module technology, delivering fully compatible solutions for industrial control panels, medical monitors, and automotive instrument clusters. The company’s patented processes also support customized requirements for high‑performance applications.

LCD Factory Operations Centered on Quality
CNK’s LCD display factory in Fujian strictly adheres to ISO 9001 and IATF 16949 standards, implementing rigorous quality control across the entire production process—from raw materials to finished products. The factory’s cleanroom environment eliminates contamination risks during the tempering process, and finished units must pass tests for hardness, light transmittance, and environmental durability before shipment. This comprehensive quality management system ensures consistent product quality for TFT LCD panels, graphic LCDs, and OLED modules, enabling CNK to forge long-term partnerships with customers such as Haier and Hytera.
