ABREX®-D
Reliability Testing for Displays / Touchscreens

Over the decades, the touch design has been changing from the simple button/knob to a display, either non-inactive or interactive touchscreen. Since 2012, OEMs in various industries start to install fancy touchscreens into their product. ABREX®-D is designed for display durability testing.


                                                                                                                                                                               

Importance of Durability Test on Display


visible defects
• Scratches, fingerprints are easily appear due to normal usage
• Scratches can be easily made under dynamic motion of human being
• Fingerprint or dirt print is another issue; either easily removed by a few cleaning step or certain coating is applied to prevent those prints
• Customer will not return or exchange the display due to those defects, but instead, the product
       
non-visible defects
• Current display/touchscreen has various functional layers of coatings, and they are transparent (not visible for the  human eye)
• Abrasion is often caused by human fingertip touch / swipe / zoom actions and other mechanical loads
• Layers of functional coatings could be damaged without the visibility of human eye
