Respond here if you want glare/brightness solution

OK, just to clarify:
We buy a screen, and then send it to you for an upgrade.
The transflective upgrade fixes the direct sunlight usability.
the touchscreen completely replaces the original. If so, would it be possible to purchase a screen without a TS, and send it to you to have a TS installed?

Thanks.

wolly - I simply itemized the process... if you have an existing touchscreen you will need to replace it

alpha_maverick - yes

what's wrong with this picture:
the 7" lilli is cheaper with the TS than it is without?!?!

edit: at least, on mp3car.com store, anyway

Sometimes that is the case... to even make matters worse, if you buy an open frame system sometimes that can be more expensive after you purchase the LCD, inverter, control board, and cables. It has been my experience sometimes it was cheaper to go to best buy and buy the whole unit rather then source from an oem distributor. Partially the reason being is based on initial cost on manufacturing lines.

I will pay the $156 for a new touchscreen if the guys from SoCal meet tell me that this works in direct sun light (if they ever invate you to the meet)

Thanatos.

to clarify once again, the touchscreen does not make it sunlight readable, you will need the transflective enhancement. The TS is just a specialized light colimating TS designed to be implemented on transflective enhanced screens.

Ok so I WILL NO PAY $400.95 to make this tiny screen readeable in direct sun light.time to make a hat for my xenac.

Thanatos.

Edit:

BTW is $401.95 no $400.95

I have a temporary (card) shroud for my lilliput. It's very effective at keeping most direct sunlight and most ambient light off the screen. That made the lilliput usable on bright days except on the few occasions where sunlight hit the screen directly (and even then it was only ever part of the screen with direct sunlight onto it). That worked pretty well except I had to have the screen set about 6" further back than was comfortable for use in order to get the necessary depth of the shroud. More recently the backlight has got much dimmer such that the monitor's basically unusable on a bright day even with the shroud.

Compared to a lot of the high-brite or transflective LCD's, the price you quoted really isn't bad at all. Personally, I'm not going to be using a touchscreen at all. (and I don't feel I'm "compromising" by doing this, I think a jog-wheel and some dedicated buttons is much more elegant, with a keyboard for entering GPS addresses) I could easily spend 50-75% of that price on backlights, inverters/drivers, various control electronics, fabrication materials, etc. Nevermind the time spent. That said, I do love a good project...

BTW, once I figure out what I'm doing for backlighting and controlling my LCD, I was thinking about designing a "light pen" that CAN work with LCD's. It CAN be done, I don't care what most FAQ about light pens say (look at what some game companies did for games with lots of BLACK in the background, they don't rely on the phosphor glow and raster scanning characteristics of a CRT, but rather they insert quick "location" frames that our eyes don't see - simplified). Anyway, I don't want to hijack this thread, so when the time comes, maybe I'll start another one.

That technology looks interesting. I just looked it up, was that developed by Iridigm (recently bought by Qualcomm)? Not sure which company owns which, etc.
For automotive use (high ambient brightness, at times), I'm personally more interested in ultra-slim CRT's. It looks like progress is being made in that field too. Again, though, I don't want to go off on a tangent and hijack this.

THANKS for this answer, I've been wanting to hear that for awhile. I have some half-silvered mirrors (about the right size) that I used for a DIY car alignment process I performed awhile ago. Maybe I'll play around with them a bit.
