In my search for a display for my CarPC project I have noticed a number of things. First of all there are few dedicated mobile display manufacturers: Lilliput or Xenarc. While these manufacturers (sold here) have done much to make small displays available to our ravenous hobby, they have done little to update the quality and selection of the products they offer. For example the best screen (high brightness, sunlight readable, transflective) is still only offered at 7". No 8,10, or 12 when consumers are constantly demanding such.
So like many others I have looked elsewhere. Njytouch offers a nice solution w/ their LCD controller cards. But finding a seperate LCD, while doable, is not ideal. Ideal would be a premade display w/ vga or dvi inputs, high brightness, touchscreen, and sunlight readable or transflective in multiple sizes.
Like these! :yum:
These displays from a company in Switzerland would be perfect. After talking to the US distributor though, the problem is not enough financial muscle to get them available at a reasonable price point say of around $3-$600 dollars.
I think MP3Car should do more to influence manufacturers to make better displays at lower prices or do more to increase members display choices. If I could find better choices than Lilliput/Xenarc surely MP3Car can as well. :peep:
So what can we do to get the Digital Logic displays sold in the store? I am down for a group-buy.
If consumers are demanding bigger/better/brighter displays as you claimed, why is your US distributor having trouble selling them?
I do understand your point I am going through the same route. At this point I am building my own LCD screen using parts bought on eBay.
There is one more option you can explore. Some board members here (tft_lcd I think) sell open frame kits that you may like.
The US distributor is not having trouble selling them to police and emergency vehicle companies and trucking companies w/ digital systems in their cabs. But the CarPC consumer is a small segment they are either not aware of (as it seemed when I spoke to him) or unconcerned about because they make enough through the other industries I mentioned. He was more than happy to sell me a few hundred if I wanted them. That is where I think MP3Car should step in.

I miss Heather. :(
Dude it was a weekend. I'm sure Stephen, the store manager, will chime in soon.
Sorry, did not know they closed the store on the weekend. :yield:

Good point about the group buy. But I'm a little confused about the specs, so school me if you will. Other than the monitors not being transflective what's not great about the specs?

The 10 & 12" monitors are LED backlit. I'm not affiliated in any way with Digital Logic, I just like as many options as I can find? For instance the transflectives you mentioned in another thread Ripp are very appealing to me as well.
I'm not saying they are bad by any means, I'm just saying their specs are not good enough to buy one without seeing it.
I also agree they seem to be much better than Xenarcs. As for the brightness and constrast numbers, I have a Xenarc 700TSV with 500nits, and it's useless. My 200nit (according to LG specs publish somewhere else in this forum) battery powered iPad has 200nits on its IPS screen and it's like 10x better.
If you get them to release their LCD manufacturer panel, we could learn a lot from that. It may be a high end Nec or Hydis, or a cheap Sharp instead...so knowing such things would help.
Maybe Xenarc over inflated their numbers, maybe they measured before they added the resistive touch (note that on their website the same numbers are claimed for the touch and non-touch model...). The viewing angles on my Xenarc are nowhere near what is claimed, etc.
Thanks for pointing this European vendor out. Their displays do look intriguing and I'll look into them a bit more.
We have an established relationship already with Inelmatic in Europe and they have similar products to the XF700 in the 8" and 10" range. Brightness is in the 800-1000 nits range for these sizes, but price jumps significantly to $900+ when going to these larger monitors.
In our experience, it's not the individual hobbyists that are interested in these units, but larger companies looking to use them for industrial and special purpose applications. As mp3Car seeks to dab into both markets, introducing these here in the U.S. is definitely a possibility. However, as you can imagine, the amount of capital needed to hold this inventory is substantial. We usually wait for a corporate or government customer to express interest first before bringing products like this on our store and offering them to the individual hobbyist. As I think you found out, it's difficult to convince distributors to sell in quantities below 100s of units at prices that can easily be translated into reasonable MSRPs for end users. Sometimes "muscle" is needed in the form of a large corporate order first to facilitate that initial shipment.
Another thing to consider in the automotive market is not just brightness, but how well the monitor is able to 'redirect' sunlight away from your eyes. That is, you can have the brightest monitor in the world and it still won't outshine the sun. Therefore, for customers seeking a monitor that appears brighter in all sunlight conditions, we recommend the Inelmatic XF700 or mp3Car Sunlight Readable Lilliput 669 in the 7" range. You do bring up a good point, however, that offerings are somewhat limited in the 8-10" range.
Lilliput just recently introduced their high brightness 7" models with HDMI & DVI. I will also try to work with them to get the 8" and 10.4" models to market quickly.
Again, thanks for the heads up on this vendor. Keep the product suggestions coming! ;-).
