Thread: 6.4"-8.4" VGA TFT LCD w/ Touch Screen

Well I would give you my opinion on the Xenarc's, but I dont have mine yet (waiting patiently lol). I would think that the Xenarc screen is the best way to go for you, based on your specs.

There is the DennisK setup, which Im not sure if your familiar with. 8.4" vga touchscreen, but only 150 nits, and only 12-bit color. You would need to purchase an extra cable, as his kit is not 100% complete. The cable goes from the touch controller to your serial port. allamerican.com has the cable for $11, but they have a minimum order of $50, which after tax, shipping and handling, gives you a grand total of $70. Dennis asks $295 for the entire kit (minus the cable) shipped. I can give you his e-mail if you would like.

But like I said before, I cant compare the 2 screens until I have the Xenarc in my hands, but I would imagine that the Xenarc is higher quality, and more suited towards your app (movie playback). While DVD doesnt look TERRIBLE on 12-bit, you can definately tell theres some colors missing. The Xenarcs are 250 nits and 18-bit, more then sufficient for DVD and other video.

Thanks InFix,

Guess I'll just have to save up =) Just didn't want to miss any other options and the one you mentioned (thanks again) is tempting... do please post a review of the Xenarc when you get it... I bet many would be interested as it seems to be the lowest priced LCD/Touch able to handle the demands that a PC is capable of.

InFix, did you ever get the display? If so which of the two would you recommend?

Lag117, I totally agree with you. Spent the last few weeks trawling around and am amazed that Xenarc is the cheapest readily available 7" VGA screen at $550 (plus, for me, shipping to the UK). However, it also appears there are quite a few good quality 7"- 10" LCD modules available, presumably for industrial applications, so it's a matter of matching one of these up to a controller to run it off your PC VGA, rather than RCS or video. Other controllers and kits available from places on this thread...

The route I'm taking is with the new Via EpiaM mobo, which will very soon be coming out with an LVDS connector for linking direct to TFT screens, and so avoiding the need for analogue VGA. Partly due to the multiplicity of 'standards', Via could only integrate support for a limited number of screen, so how it chooses these will be interesting, but in opting for the LVDS standard this selection will be more towards newer screens, rather than picking up old lap-top screens and just connecting them. I'm hoping (and trying to persuade them -- lil'ol'me!!!) to go for modules/manufacturers that include smaller size screens, as I feel this is an important growth market and, er, it's what I want.

In the meantime, I'll either get a touch-screen Xenarc, ot the TM701L being offered through DigitalWW if the spec of the LCD module is good enough. Armen's checking up on that -- see the UPDATE thread...

Where did you read the spec of 250 nit for Xenarc 7" WVGA?
