ABREX®-D
Your touchscreen and display durability tester

Importance of Durability Tests on Displays

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

Description

ABREX®-ABRASION, is a soft-chemo-mechanical fingertip & hand abrasion tester. The simulated wear pattern matches reality with 99% accuracy. It is a highly complex abrasion process which involves:

• A 45° angle impact driven by a dynamic pneumatic cylinder attached with a viscoelastic fingertip under a defined load;

• Then a friction rubbing or tumbling motion between the sample and a textile containing dirt, dandruff, oil, sweat or various types of testing liquids;

Followed by a retraction movement with or without the contact at the surface depending on the application.

ABREX® can be upgraded to ABREX®-A & ABREX®-D & ABREX®-E respectively.
* ABREX®-A can run both standard abrasion test and special “swiping mode” with test condition of friction
path of 20mm @ 5N @ 2Hz. Other frequency, friction path and load can also be achieved upon request.
Application

Displays are nowadays widely integrated into various consumer products:

Automotive: car, truck, bike, motorcycle

Telecommunication: mobile phone, pad, watch, E-book

White goods: refrigerator, washing machine, dish washer, stove

Small Electronics and many more

Visible defects

• Scratches and fingerprints can 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 steps or certain anti-fingerprint coatings are applied to prevent those imprints.

• Customer will not return or exchange the display due to those defects, but instead, the complete product.

Non-visible defects

• Current display or touchscreen has various functional layers of coatings, and they are transparent (not visible to human eye)

• Abrasion is often caused by human finger touch/ swipe/ zoom actions and other mechanical loads.

• Layers of functional coatings could be damaged without the visibility of human eye.
