15x view of pixel matrix - take a look!
I painstakingly used a 15x loupe to check the pixel pattern for both my old LN40B530 and my new UN46EH5000.
When I first got the new one (UN46EH5000, manufactured in March of this year), I could see that it was not up to the superb quality of the older LN40B530 (manufactured in 2008).
I cannot take photos of the magnified views, as I haven't figured out how to focus my camera (even in macro mode) tightly enough. But, I have created a likeness of the two pixel patterns using MSPAINT, as close to what my eyes could see using the 15x loupe.
The first photo (LEDpixelmap.bmp) is what the newer one (UN46EH5000) looks like - a simple square pixel map alternating between green, red, and blue, with black borders.
The second photo (LCDpixelmap.jpg) is what my excellent older LN40B530 looks like - a much more complex pattern of two different sizes of alternating "greater than" signs in the color sequence (green, red, and blue). This older pixel pattern may be why it looks so much better to the eye - there is much more in the way of pixels, size and slant, to better represent the image to be presented.
I wonder if Samsung, or *anyone* makes panels using this earlier, more complicated, and more eye pleasing method.
Please, if anyone on here at AVSFORUM knows anything about LCD panel design and manufacture, please advise in light of what my 15x loupe has revealed to me.
More to the point, where can I get a new panel made like the older LN40B530, with its complex pixel pattern map?
