How to detect the screen appears a small crack on the panel oled module

Screen panels are very sophisticated things in the manufacture and use of the process if done incorrectly , may cause the screen suffer damage. So Apple is how to detect whether the device's screen was damaged , there were minor cracks and other problems?

Screen panels are very sophisticated things in the manufacture and use of the process if done incorrectly ,mini lcd module may cause the screen suffer damage. So Apple is how to detect whether the device's screen was damaged , there were minor cracks and other problems?

Last week, the U.S. Patent and Trademark Office published the acquired patents, these patents and manufacturing processes, improvements and other related small adjustments . Here we highlight a set of apples used to detect cracks in the screen system patents . Apple's use of external resistors way to detect trace debug screen panels or other devices on the crack pattern .

This system typically includes screens and data processing circuit . Screen with a display panel may be , its periphery is the external resistor tracking facility . Screen intermittent detection circuit can detect external resistor tracking facility fracture, while the data processing circuit can determine the seriousness of the display panel is being damaged. If the display panel is severely damaged, OLED Display the data processing circuit can also be issued a warning to the user's screen destruction issue.
