Optical Filters

Keyflex provides high-grade optical filters in the form of Optolite Clear HSR grade, designed to improve the protection, readability, and performance of LCDs and other electronic display applications. Optolite Clear HSR optical-grade filters offer a robust material solution with high temperature resistance, excellent scratch resistance, and strong impact resistance.

These optical filters are particularly suited to LCD displays and control interfaces where durability and clear visibility are essential. By adding a protective optical filter to the front of a display, manufacturers can help reduce common problems associated with exposed LCD surfaces while maintaining a professional and high-quality appearance.

Protecting LCD Displays

LCD displays are widely used across industrial, commercial, medical, automotive, and electronic equipment. However, the front surface of an LCD can be vulnerable to environmental and everyday handling conditions. Keyflex optical filters provide an additional protective layer to help overcome several of these challenges.

Common LCD problems include:

• Soft front surface polariser: The exposed polariser on many LCDs can be vulnerable to scratches, dirt, moisture, fingerprints, and general handling. A suitable optical filter helps protect the display surface from everyday wear and contamination.
• Front surface reflections: Reflections from surrounding lighting can make LCD screens difficult to read. Optical filter solutions can help reduce unwanted reflections and improve display visibility in challenging lighting conditions.
• Restricted viewing angles: LCD construction and operating methods can sometimes result in limited viewing angles. Carefully selected optical filter solutions can help optimise the viewing experience for different display applications.
• Ultra Violet degradation: Displays used outdoors or in areas exposed to strong sunlight can experience UV-related degradation. UV-resistant optical filter materials can provide additional protection against prolonged exposure to ultraviolet light.
• Electromagnetic interference: Electronic displays and control systems can be affected by electromagnetic interference. Optical filters can be combined with appropriate shielding solutions to help address EMI requirements in sensitive electronic applications.
• Sourcing of bezels: Finding suitable bezels for different LCD sizes is not always practical or cost-effective, particularly when products use a wide range of display dimensions. Custom optical filters can provide a flexible alternative designed specifically around the display and surrounding enclosure.

Custom Optical Filter Solutions

Keyflex can provide optical filter solutions tailored to individual display requirements. Filters can be manufactured to suit different display sizes, shapes, and configurations, helping create a clean and integrated finished product.

Custom cut-outs and dimensions can be incorporated to accommodate displays, indicators, buttons, LEDs, switches, and other interface components. This allows the optical filter to work as part of a complete human-machine interface rather than simply functioning as a protective screen.

Durable and Reliable Materials

Optolite Clear HSR grade is designed for applications where durability and optical performance are important. Its resistance to high temperatures, scratches, and impacts makes it suitable for demanding environments where standard display protection may not provide sufficient durability.

The material can help extend the service life of display interfaces while maintaining a clear and professional appearance. It is particularly useful for equipment that is frequently handled or exposed to challenging operating conditions.

Applications

Keyflex optical filters are suitable for a wide range of applications, including industrial control panels, medical equipment, electronic instruments, automotive displays, commercial machinery, communication equipment, and other LCD-based products.

By combining protection, optical performance, and custom manufacturing capabilities, Keyflex provides reliable optical filter solutions designed around the specific requirements of each application. From initial design and material selection through to finished production, our team can support customers in developing durable and practical display interface solutions.
