Hi everyone.

Yesterday I turned my Gamebuino on after months of hibernation. I noticed that the left side of the screen is brighter than the right side. Can someone tell me what happened? How do I fix this? It's annoying to look at because it creates sense of imbalance.

Thank You

One obvious way to fix this is to replace the display. I think you can get it for 10€/$ on various places.

I think this is a common problem of non-expensive displays (and even more expensive ones) -but especially annoying for cases, where the backlight comes from only one direction: the reason why unidirectional backlight does not look "uneven" from the beginning, is that there is a reflective and light-dispersing layer behind the TFT layer. This layer can change its dispersing effect over time due to mechanical and/or chemical processes (i.e. oxidation, slight deformation due to relaxation processes after production). On bigger screens this results in clouding effects and here this means this strong difference in brightness from left to right.

Thanks for the reply. It's sad if there is not other way other than replacing the display. I rarely use the Gamebuino, and I always keep it in the safe place. This is another pic from below. There's light from the left area only. I thought maybe the it can be blocked by something to reduce the light. Maybe..

I think  replacing the display is solely the obvious way. Aurélien and his team are back tomorrow I think. They are the specialists for this display and could know another trick or two to fix it...
