Defective pixels on the TFT
« on: February 27, 2011, 08:21:26 pm »
Update: It appears to be some kind of impurity inside the transparent plastic cover.

Some companies allow a certain number of defective pixels, so they might not take it back. I suppose, in the end, it depends on how long you're willing to wait and how much bureaucracy you're willing to put up with.

Even $200 computer monitors have this problem, it isn't that big a deal. However, if you can somehow get a program to quickly turn on and off the affected pixels, they sometimes fix themselves.

You could try that through BASIC first.
@cfxm and if that doesn't work ask one of us SH3 coders to code a pixel flicker thing for you. We just need to know the coordinates.

List of stuff I need to do before September:
1. Finish the Emulator of the Casio Prizm (in active development)
2. Finish the the SH3 asm IDE/assembler/linker program (in active development)
3. Create a partial Java virtual machine  for the Prizm (not started)
4. Create Axe for the Prizm with an Axe legacy mode (in planning phase)
5. Develop a large set of C and asm libraries for the Prizm (some progress)
6. Create an emulator of the 83+ for the Prizm (not started)
7. Create a well polished game that showcases the ability of the Casio Prizm (not started)

Well, I tried locating it via BASIC and the pixel seems to be fully functional.
HOWEVER, the glitch appears to be INSIDE the glass(?!), because those TFT pixels are clearly BELOW this black blob.
Also, it depends on the angle. (I can see the "defective" pixel jump)

Some type of dirt or impurity must have gotten into the glass during production. I wonder what the state of their production line is if that's the case.

I wonder if you can remove the glass then.

I hope I do not get too many of these. On my old PC monitor there are some dead pixels and it can be annoying during games.

     I'd have to agree with DrDnar. This is a known phenomenon, and some companies may not do exchanges for such a thing.
     
I personally don't know if I'd bother with the hassle. if it were multiple pixels in such a short time period, then yes. I would definitely exchange it. It does suck that it happened to such a new product though. :(

To be honest I am more scared about TI's color screen than Casio, because historically TI calcs are known for missing columns of pixels after a while, although this was mostly on older calcs and they are black and white LCDs.

I remember last year, over 90% of the ti83s in my math class had bad rows of pixels.

Ouch X.x. Sometimes I wonder if it's just caused by dust or something...

Lol the thing is that in some places in China (where the calcs are made) it's pretty much impossible to get better working conditions, so people will certainly not retailiate by sabotaging stuff. X.x
