Electronics Product Development: 3 Tips for Detecting Touch Controller Failures

In electronics product development, touchscreens can be difficult to stress test; and whilst there are several sophisticated systems available for touchscreen stress testing, there are other ways to get the job done – like a low-tech approach… For example, take a look at this rig built from a child’s toy.  Our engineer built it as part of the debug process to try to fix a failed touchscreen unit. Thanks to our brightly-coloured debugger, we discovered that the touchscreen controller chip itself was unreliable.  The rig kept tapping the screen over and over and over again.   However, what the debug process uncovered was that it took slightly more than a mere tap-tap-tap motion to uncover the bug.  So: Tap-tap-tap motion = unit functioning normally. Tap-slide-and-up motion (closer to an actual [...]
