‘Optically Bonded’ Projective Capacitive Touch Screens deliver enhanced readability to TFT displays
Today many display products are required to work in extreme conditions where the readability and robustness of the display and associated touch screen are critical. Typical parameters that have to be met are resistance to moisture and dust/dirt ingress, scratch resistance and shock/vibration.
FurtLeading display innovator GPEG International has, in conjunction with its TFT display manufacturing facility in Asia, developed ‘Optical Bonding’ processes that eliminate the problems associated with conventional PCT cover plates while at the same time providing a number of readability enhancements.
‘Optical Bonding’ has the following benefits:
• Display designs are thinner and hence lighter
• Prevents ‘fogging’ of the display as there is no air gap
• Sunlight readability is greatly increased by up to 4x
• Scratch resistance increased by up to 3x
• Resists moisture, dirt and dust
• Wide temperature operation without any change in performance
GPEG has a program to incorporate the ‘Optically Bonded’ process to its TFT displays over the coming months, currently available for mass production are 3.5, 4.3, 5.0, 5.7 and 7.0 inch TFT systems that have a variety of interface options, resolutions and backlight brightness’s.
