  • The idea that credit is so important is an artifact of the system. Sharing is its own reward. Most so called inventions and discoveries are things that others have already done or will do anyway but get no credit for. This is from someone who has published peer reviewed papers and has many patents. I still believe the credit issue is largely bullshit. The exception is that yes you kind of have to play the game to work the system and it is important for that reason.













  • There are various designs of backlights. They typically have a stack of loose components in an assembly. By loose I mean not totally fixed but not too free. They have to free float enought that temperature changes do not cause issues. They also have to not stick, warp, or buckle over time. Harder to engineer then you might think.

    So consider what might happen if for example the top backlight film might buckle some then stick to the back of the lcd. The film might deform which would change its optical properties. Then later thermal cycling might cause release. It might do same elsewhere.

    Not saying this is mechanism, but just example.

    Edit: Keep in mind the LCD is glass, and the backlight components are plastic. Very different thermal expansion coefficients. Then add LED or CCFL lighting and you have a big changing heat source. Add on top of that humidity changes too.



  • Sounds to me like the backlight behind the LCD. They have components which could potentially sag, stick, or warp. White screen is probably best way to see. Also look at various angles. May be more visible at some angles then others.

    Hard to unsee. I know this feeling. I used to work in the industry years ago. Displays are never perfect and hard to unsee things once you see them especially when it was part of your job.
