The above comment and others got me to thinking. If the cloudiness is *possibly* due to the shifting of the fluid (I am sure glass manufacturing tolerances could enter in the equation too), causing a thinning out of the fluid in certain regions of the screen... thus letting some light seep through. Then what if this fluid could be redistributed in one way or another- building on the "lay it on it's face" for a while concept.
While static forces may be adequate in some circumstances, I would imagine the viscosity of the fluid might be high enough so that some additional vibration besides static weight may be required for this to be effective.
I thought to myself, I wish I had a shaker table to place the display on, an in a controlled fashion, apply low levels of vibration along specific axes, or better yet, in a circular pattern to help redistribute the fluid more evenly. Alas, I don't have a shaker table. Then, when I saw the above comment, I saw a poor mans shaker table- the car.
Now, I do not yet have a display, let alone one that has this problem. But I was planning on placing an order for one today. and was hoping that a remedy might be found for this.
So, if anyone is willing, that has a very cloudy display, try placing the set face down (Flat) in the back of your car (back in it's box hopefully), and drive around, trying to choose a slightly rough road (but not too rough!), for a while (the theory being- the longer, the better). Maybe rotating the display so that each edge (or end) is closest to the front of the vehicle for part of the trip (if possible- I know it's big) will help too. I am not sure what the dynamic forces need to be but in theory this could help redistribute the fluid and "clear up" the display.
Years ago, to degauss tube type TV Sets, and get an even color distrubution, a technician would have to use a large ElectroMagnetic Ring, plugged into an AC source that would set up an AC magnetic field, which he would then wave slowing in a circular motion in front of the TV set, which would then level out and remove the magnetic hot spots on the picture tube. He would keep doing this, for a while, while also backing away from the TV until he was a long ways away 10-15 feet, at which point we hould unplug the electromagnet and then the picture purity would be nice. This problem reminds me of that.
Just a thought, but it has a chance- for what it's worth.
