Screen: Glass is really easy to break…

Recently we get report about some screens are broken. The bad one looks like this:

On some screens, white lines appear across the whole display.
On some types of screens, if there’s only a small crack, the line may disappear over time—but it reappears when displaying rapidly changing images.

It shows some unexpected line on screen. When we get the returned screen, and find under touch screen the display glass corner is broken…

The glass on the red circuit is cracked. It’s super easy to break if you press on a corner—even a tiny crack can be serious. You’ll only notice it if you look at just the right angle with strong lighting.

From the picture, I find its inside chip is so thin, and looks like made by glass, I think it should be Silicon, used to driver every line on the screen 🙂

For DIYer, please be very careful when install this part, only 0.2mm so it can not stand any force. We will also be very careful when package them.

The glass corner is fragile, here are some bad examples..
