As mentioned in part 1 of this article, it has been known from the beginning of LCD, but not well informed by retailers to consumers, that LCD has an inherent viewing problem when the angle of view is off center, and depending on the LCD, the color, brightness, and contrast, drop considerably as the viewer moves from a center position (90 degree straight to the panel) to angles that are typical of the sitting arrangements of most family rooms, whereby viewers gather around the screen, and although they may still view an image, it is typically not of the same quality of the image perceived by the person viewing straight to the set.
This is more noticeable when...

Does OLED have angular dispersion as good as plasma or is it limited as you have explained for LCD?

Jborchel,
From the appearance of both prototypes from LG and Samsung at CES 2012, their mage appeared even stronger than plasma in light output and contrast and viewing them from the side was at least as effective as plasma, however, they were prototypes and we have to wait until the street units are out, calibrated, and reviewed to confirm their virtues (second part of this year). I suggest you to read my other articles about OLED.
The OLED demos were stunning but as I said in my articles the first thing I would do is an ISF calibration to make the image less stricking for prolonged viewing, especially on a darker room. Once that is done, the angle-of-view has to be retested.
In my opinion, by design, Samsung's OLED has a better chance to a better angle of view than LG's OLED because their RGB organic subpixels are at front (like a plasma with phosphors) rather than LG's white OLED light in the back with color filters at the front, which is like an LCD design of light coming from the back. The appearance of LG's OLED at CES was as stunning as Samsung's and LG claims that their OLED has a great angle-of-view.
Best Regards,

A major issue with the polarizing layer is that images can become unviewable in brightly lit rooms. This is also a problem with electronic displays used in cars and aircraft where they can eliminate the possibility of wearing polarized glasses.
I've been a photographer for many years and am quite sensitive to colors and editing soft ware so I am very sensitive to color and brightness shifts. We should not neglect aspect ratio when talking about off axis viewing either. Regardless of how true the brightness and colors are maintained once you pass much beyond 45 degrees, the aspect ratio squeezes the image into a tall, skinny presentation that is pretty much useless. We've all, or at least most of us have seen wide screen images on a regular TV screen. This is the same thing carried to an extreme. Even a photograph is subject to the same viewing angle distortion of the aspect ratio.
I have an old 40" Samsung that performs admirably with brightness and lack of color shift out to where I find the aspect ratio to be bothersome. Of course they advertise the useful viewing angle well beyond where it become useless because of aspect ratio distortion.

Hi Roger,
You brought up the aspect ratio comment before as it would be a problem of imaging (TV or otherwise) and I wonder if you ever thought that a real set of objects placed at the same level plane from each other, no depth so you can only see their front, in a window the same size of the TV screen, would appear to the viewer the same way he/she would be seeing them if they were video or photo representations on a similar TV screen size captured at the same single level plane of depth of the real objects.
Would a real window frame maintain the same aspect ratio to you when you see it from a side angle? No. Why the aspect ratio of a TV frame (and the image within it) should not follow the same logic when seeing it from the side?
The objects within the real window and within the TV screen appear both as skinny when viewing them from the side, they are not actually taller than their front view (like an anamorphic representation would) but the side view makes the width less wide, so yes they appear to have a different aspect ratio than when viewed from the front, but the real life objects do as well.
