Thread: So, give us new LCD touchscreen options!

i finally found the peice of ****
TX18D11VM1CAA data sheet. This is the absolute best i can do. Unfortunately i dont think it has the CIE info on it

cheers geezer. shame there is no CIE stuff but JCDs order the tubes now so fingers crossed!

400nit from a side mounted CCFL

wonder what our design will look like!

Allright everyone, another status update. It turns out the place in china also has the exact inverters we need to power the tubes, I have added some to that order. So now we wait for the tubes!

Brilliant work guys!! I knew of your efforts from my time whoring in OT, but now that I've finally read this thread I am really impressed. Keep up the good work. And if you need a beta tester.........

Well depending if this works, I will be selling the extra parts that I dont use, to try to offset the high cost of getting the samples in.

i figured no one needed that damn data sheet anymore. But it ****ed me off not being able to find it. And if i get ****ed at something it either gets smashed or i make it work one way or the other. So i just couldnt stop looking till i found that damn thing

hey they still are helpful for reference, i've put them away somewhere safe for a rainy day.

Status update, I wired the money today. So they are saying 3 days to make the tubes and 3 days in-transit. So maybe by week after next we'll be able to start testing!

hey guys, I've been doing pretty much the same research & have come to similar ideas as you guys have here in this thread.... I have a 12.1" widescreen that I am using from a laptop & I have dissasembled it & am going to be able to have the whole rear of the lcd exposed to my light source...I have built a stainless steel "pan" type box that the lcd will sit on & I have built it to be 2 1/2" deep.....up until I read this thread I was considering either multiple cold cathodes or I was thinking of putting an aray of 150-200 high bright led's (20,000-26,000 each).......this thread however showed me the led array that was made to be a backlight for an lcd & I see that they don't use just white....I saw that they are using white in combination with other colors....& some sort of control for white balance....these are things I haven't considered as far as color tempature is concerned. this is having me reconsider the led approach altogeather.....

I have played around with lcd's for a while.....I even set one up with a xenon bulb as a backlight....it was supper brite but ran way too hot....I was afraid the lcd would melt....it also wasn't dimmable...which is a definate requirement to my new install. My question to you guys is that if I decided to go with several cold cathodes what would be my best option as far as powering & dimming......I think the ultimate would be with a light sensor auto of course, but would settle for just a pot type adjustment that I could have a knob to control briteness, I wouldn't want to have to have several pots on several power supplies though...any ideas?

also, just a note, i picked up a sheet of 3m's vituiluki anti glare film at my local micro center...it was packaged as an add on anti- glare screen for lcd.....it was made for a 15" lcd & cost $42.99 but is trimmable to size....I tried it in the car & it defanately makes a difference.....with my liliput totally washed out from the sun I slipped this in place over it & it was defanatly readable when it wasn't without it! if anyone is interested in this I will check the packaging & give you #'s off the package, or any other info I see that may help you locate one....it was packaged by 3m & appeared to be a readily available item...I have seen it in that store for a while, but thought that was a lot of money for a thin piece of translucent plexi untill I started doing research on lcd's & learned all about 3m's vituluki concepts....when I saw this vituluki on the package I just knew I had to play with it.......
