Here are 2 pictures I took today of the EBY701 Transflective screen. It is definately readable under sunlight. The screen came out darker in the picture comparing to looking at it with my own eyes. Like I said before, I've never owned another touchscreen so I really don't know how this stack up to anything else. I really wish I can do a side by side comparison with other screens, especially other transflective screens.
Nonetheless, this screen is probably the best size/shape for my car without making any modification to the dash/bezel. Measuring ~7-5/8 inch x 4-1/2 inch (although still slightly wider and shorter than what I would have hoped). And I'm glad it doesn;t have that ugly gold lilliput logo.
Anyway, so far so good. I'll play around with it more and possibly take some more pictures (maybe in my honda del sol with the roof off). I still think the price is pretty steep for a 7 inch screen, but comparing to other transflective/sun-light-readable screen it is still a hell of deal for under $450 (after cashback rebate).
first picture: sunlight shining directly onto the screen through the front passenger side window.
Second pic: Reflection off the dining room lights. Although the screen seems to be somewhat glossy, reflections tend to be diffused and with a pinkish tint.
