Comments on: Nexus One display and subpixel pattern

The reason to have that kind of a sub pixel level might be to get good luminance.
Luminance is derived as 0.2126 R + 0.7152 G + 0.0722 B (brightness of the light coming from display), and to reproduce bright white either they have to change the intensity of Red and Blue (how its done in CRT display’s) or have less area for Red and Green compared to Green. In LCD its not a problem because they have a Bright white light as back light and to show white color on screen they just make that pixel transparent.

I have a Droid. When I received my Nexus One, I immediately notice that the text display on the screen is terrible compare to the Droid. Don’t understand why Google ship such lame OLED on us?

>” … I’m sure I’ve read somewhere that it’s even more sensible to red.”

Nope. Most sensitive to green (around the 530 – 550 nm mark). Considerably less sensitive to red and green by about 1-2 orders of magnitude (See: http://www.yorku.ca/eye/lambdas.htm and look at the dotted line; that is your colour vision. The scale is logarithmic, so a plus or minus one on the relative sensitivity axis is a difference of ten times the sensitivity). So the relative pixel size makes sense.

>” I guess this may be due to red being a danger colour for humans.”

I’m sure I read somewhere that this is purely cultural – that in some cultures red stands for purity, joy, good luck, happiness, prosperity, etc., but I’m not sure. I will have to Google it.

Come to think, this may have worked better had the red-blue ordering not changed every other row. I didn’t notice the green fringe on the right side of light areas until I went looking for it, but I noticed the red-blue-red-blue sawtooth artifact on the left within a few minutes of using the display. Had there just been a red or blue fringe on the left, I might not have noticed.

I wouldn’t say this is hardly noticeable; this has bothered me since the day I received mine. Photos look fine, but text and vector graphics have a horrid red sawtooth pattern on one side, and a green fringe on the other. It looks like botched subpixel antiailising. I’m debating returning my N1 and getting a Droid (or just waiting to see what comes next) as a result of this. I could learn to live with this, but it’s hardly desirable.

Hopefully other OLED displays will use a different subpixel pattern.
