Industrial Markets

Electronic displays such as LCDs, CRTs, OLEDs and LEDs are widely used in diverse commercial and industrial applications including:

  • Industrial Process Monitoring and Control
  • Mobile and Stationary Test Equipment
  • User Interface Solutions such as POS and Mobile Computing
  • Telecommunications Equipment
  • GPS and Navigational Equipment
  • Industrial Vehicle Control Systems

Image quality is critical to data viewability and integrity, and must meet a wide range of optical, electrical and mechanical performance standards. For instance, in addition to reflection or glare control, industrial displays often require a protective cover glass to provide impact resistance and prevent moisture ingress, as well as a shielding solution for electromagnetic compatibility.

Dontech, Inc. designs and manufactures a variety of optical coatings, substrates and display solutions that can be used to improve ergonomic and regulatory performance of displays and touch screen monitors used in industrial applications. These include:

Coating/substrate Application Regulatory Criteria
Antiglare (AG),
anti-reflective (AR),
AG/AR coatings
Reflection reduction / glare control ISO 9241 system ergonomics and viewability
AG, AR, AG/AR coatings, polarizers Contrast enhancement ISO 9241 system ergonomics and viewability
Transparent conductive coatings (ITO), or fine conductive grids (FCG) EMI/RFI shielding, electromagnetic compatibility IEC-60601, CISPR11, BSEN-55011; System dependent
Polycarbonate, acrylic, chemically strengthened glass Impact resistance; fluid ingress protection UL60950, UL60601; ability of display to withstand 0.5 kg, 50mm ball dropped from 1.3 m; IEC 60529 for ingress protection (IP54/NEMA 4; IP65/66/NEMA 4X
Scratch/abrasion and chemical resistant coatings Improve durability and life of display Tested per ASTM-D-1308 (chemical resistance); ASTM D1044 (Taber abrasion test); System dependent
Solar loading and IR blocking coatings Reduction of thermal loading on display ASTM-E-424-71 (test method); System dependent


The modification of COTS (commercial off-the-shelf) displays to achieve compliance frequently includes the addition of optical filters or coatings to address the following display performance issues: 1) reduction of specular and diffuse reflections to improve high ambient light readability; 2) reduction of EMI/RFI emissions and susceptibility to achieve electromagnetic compatibility; 3) impact resistance to meet UL or ruggedization requirements; 4) resistance to chemicals, scratches and abrasion; 5) resistance to thermal loading (solar and IR blocking coatings); 6) viewing angle modification to increase or restrict viewing angles.

Dontech – Enhancing Optical and Environmental Performance of Industrial Displays

Dontech Enhanced Display Solutions (EDS) specialize in the application of optical films, coatings and components to improve the performance of electronic displays in demanding environments such as military, aerospace, medical and outdoor environments.

Dontech integrates optical products into LCDs and bezels for its customers. COTS displays and touch screens can be customized to improve the optical performance, operating thermal range, EMI/RFI emissions/susceptibility, and mechanical durability. Dontech enhanced display solutions allow the display to function properly in demanding situations, such as direct sunlight, low or high temperatures, or in other harsh environment applications.
