from another thread I saw this and I thought that it might be interesting on its own.. has anyone experience with multiple LCDs that had widely varying viewing angles? readin the below quote(in blue), it seems that the wider the viewing angle, the less light transmitted thru the LCD panel(subject to ymmv of course)?

Can you please provide a general overview of the trioLCD technology?

Our trioLCD technology is a passive enhancement/modification process applied to a standard transmissive LCD display. This process provides a fairly unique proposition in that it turns a normally transmissive display into one which can be used in outdoor applications as a transflective display without any change to the electrical or mechanical characteristics of the display.

We apply this technology to various transmissive displays including those from the manufacturers Sharp, NEC, Samsung, Quanta, Sanyo, Toshiba, CPT, Chi-Mei, Hannstar, LG, PVI, BOE/Hydis -and maybe a couple other manufacturers that may be skipping my mind. That being said, the trioLCD process works better with some screens than others. Generally, those using a PVA, MVA, or other wide viewing angle technology have not taken so kindly to our process as the tranmissivity of the displays are very low to start with (in the 3-5% range compared to that of a normal TN TFT LCD with a transmissivity around 7-10%).
We have had very good results with many of the NEC displays for 5.5" to 10.4", Sanyo/IMES/and sometimes LG in the 12.1 & 13.3" range, and Chi-Mei/CPT in the 15" category. However, every new model display that a manufacturer comes out with seems to have slightly different to completely different optical characteristics -so, the generalities from manufacturer to manufacturer could change with newer models.

Also, in addition to transflectivity, the trioLCD enhancement generally allows for 20-100% increased light throughput from the original backlights due to more efficient flow of light -again, we do not change any of the mechanical or electrical aspects of any of the displays.

As you mention in the other thread, contrast ratio is going to be on the order of 1500:1 from the Samsung's using PVA crystal alignment. I figure that should increase the perceived brightness in a dark projection room.

That is a very surprising figure, though (basically half the transmissivity).

I bought a Samsung 173P+ a couple weeks ago.

When I bought the display, I was hesitant because it was 27% dimmer than the non-PVA models. I asked around, and everyone said it is a function of more than just the panel. That said, I can tell you (as expected) the display maybe appears around 27% dimmer than other technologies. The question is, is the backlight souped in this thing to compensate, or is the panel just around 27% less transmissive? My guess is that the backlight is run of the mill, and the figures from the article are too generalized.

Off topic stuff :

I haven't stripped it, but I found this information on the standalone panel. There are apparently no FFC issues by design in the Samsung 17" 1500:1's (they all apparently use the same panel):

Don't take my word for it, though. I'm still worried.

Oh, FWIW if you are a Mac user: there IS a Mac version of MagicTune and MagicRotation. It was the other risk I took when purchasing the display. Every site and review claims there isn't. I literally stumbled across the version by accident.

You have to download it off Samsung's site, though. It is only version 1.0. I can say everything works, but if the computer ever goes to sleep, you have to reboot before further adjustments can be made. And, I haven't fully tested this yet, but it seems the display will not remember new settings unless you first close the software, then shut the display down before the computer. Definitely some bugs to work out there.

Hope that helps a bit,
Mark.

....my guess is they used the same backlight but figured the increased contrast would make up for it.... which makes a kind of sense.... hows it look to you though? would you take 27% less light for the incredible contrast? ,,,though lets see.... you'd have to go from a 120" screen to an 84" screen(very roughly) to maintain your brightness level , but you'd have great contrast...hmmmm... interesting tradeoff I guess, one of those "I'd have to see to decide" things...

good point, my old compaq 14" (verry narrow vision angle) tft looked like it was much trasmissive but never meassured as i did with the hami.
