So, give us new LCD touchscreen options!

Ok, I have finally tweeked my carPC and it is exactly how I want it. It works every time, ALL the time... and for those of you who have built these things know that is a feat

But my stupid Lilliput has that 'ghost image' problem as well as syncing with the display so every 3 out-of 10 times it comes up blank. How frustrating to have the LCD be the problem in your design!!! Plus, don't even get me started on the brightness!

So who has info on when/if a new HIGH BRIGHTNESS 7" touchscreen will be coming out?!?

There has to be something on the horizon, right!?!?

i'm looking!!! I found some 300cd/m2 but with that reflective technolgy to make them go brighter in daylight and a 5wire TS (bettert than 4 wire) but they cost £500! ($900) so i doubt you would want to payt hat much!

if anyone has a smached Xenard take the LCD apart and post lots of high res pictures - maybe we can design a new LED backlight system.

From what owners say around here 7"s have non-standard (for video cards) resolution. So, if a new one comes out, it would be wonderful to have one with more standard resolution

Josh, do you have any exploded pics/diagrams of the panasonic and hitachi LCDs you could send me?

I can take some more if you want scouse

this is the lilliput raw panel

and the diffusers I pulled from a bigger LCD

**jcdillin** · 04-12-2005, 07:24 PM

yeah on the hitachi screen, the panel comes off the backlight module

Has anyone tried to use electroluminescant material as a backlight for an LCD? I was on a website the other day that sells it in sheets big enough to do a 10 in screen. I was thinking it might give off more light than just a few LED's.
