Analysis of Cover/Screen Hardening Technologies – EDL Display LCD Factory Ensures Durability

In the display device industry, cover/screen hardening is vital for enhancing product longevity.

  EDL Electronics Co., Ltd, a professional display LCD factory, utilizes chemical strengthening as its core hardening method. This process employs potassium-sodium ion exchange to create a dense surface structure, achieving 6H hardness (no damage under 6H pencil testing). Ideal for medical, automotive, and industrial applications, EDL’s hardened covers protect TFT LCD displays, graphic LCDs, and other screen types from scratches while ensuring long-term reliability.

Precision in Chemical Strengthening for TFT LCD Displays

  EDL’s automated production lines optimize chemical strengthening for diverse screens, including graphic LCDs and TFT LCD displays. By precisely controlling ion exchange parameters, the factory ensures uniform stress layers that enhance scratch resistance without compromising optical clarity. As a trusted display LCD factory, EDL integrates hardening processes with display module expertise, enabling seamless compatibility for industrial control panels, medical monitors, and automotive dashboards. The company’s patented workflows further support customized solutions for high-performance applications.
