This laser device can repair the OLED display of phones + video

The failure of OLED displays has been a big problem for phones until now, as the cost of replacing them was usually very high. But now a new laser device has been developed that can repair old iPhone or Android phone panels even while the screen is still on.

“Scotty Ellen”, from the YouTube channel Strange Parts Recently, he published a video in which he managed to test this attractive laser device. The current device uses the same technology and production technique of OLED panels and can help to solve the problem of displays that have lines on their screen.

Repairing the OLED display of phones in the same way as their production

OLED panels are produced using a process known as “excimer laser irradiation” (ELA). In this process, a layer of amorphous silicon is converted into polycrystalline silicon using a pulsed laser to form microscopic conductive connections. These connections connect all the pixels of the display to each other. If any part of this communication network is disrupted or cut off, other parts will also suffer and display defects such as vertical lines.

This device examines the structure of this OLED panel using a strong microscope and then repairs and restores faulty connections with the help of laser technology. This mechanism can be used even when the protective glass of the display is on it. In addition, it is possible to repair the panel while the display is on, so that the operator can clearly see the problem. Of course, in some cases, it is necessary to remove the protective glass from the screen.

This device will help users to repair one of the most expensive parts in phones in the simplest way and at a low cost. Before, in most cases, when there was a problem with the screen of mobile phones, especially iPhones, there was no other option but to replace the screen, but now we can finally hope that a way to repair the screen has been found.
