Touch Screens

WPG Americas offers a broad array of touch screen solutions and we are happy to design a custom solution to meet your needs. WPGA supports the following technologies:

Resistive (4-,5-,7- and 8-wire)
Capacitive & Projective Capacitive

Filters

Anti-Reflective (AR) Coated Glass
The Multi-Layer Vapor Deposition Coating on Anti-Reflective Coated glass is designed to minimize reflective and maximize transmittance.

Anti-Glare (AG) Glass Matte Finish
AG Glass with Matte Finish is chemically etched glass that has a slightly textured finish, either on one side or both sides, reducing reflection by scattering light directed on its surface.  This softens the image of direct light sources visible in the reflection of the viewing area.

EMI/RFI Shielding
This ITO conductive coated glass has conductivity levels ranging from 5 Ohms/sq to 350 Ohms/sq.  A typical EMI/RFI shielding value for LCD display is approximately 9-15 Ohms/sq at 89% visible light transmission.  Transmission is reduced as the Ohms/sq level drops.

Thermal Overloading

IR blocking filters are designed to reduce the thermal loading on LCDs used in direct sunlight, such as a marine, military, outdoor signage applications etc.  By significantly reducing the transmission of near-infrared and infrared radiation, IR filters reduce electronic display temperatures when exposed to direct sunlight and elevated thermal loading.  This also minimizes display “brown out”.


Protective Filters

Optical grad substrates used to manufacture filters include polycarbonate Lexan, acrylic, Plexiglas, glass and other transparent materials. Substrates are selected based on their optical and mechanical properties, their cost and the intended application where the filter will be used.

Vandal Shield
Can either be a film applied to the LCD glass, touch screen, or a sheet of protective polycarbonate taped to the surface of the LCD. Vandal Shield applications help to protect LCD panels in environments where the display is unprotected or unsupervised.
