According to analyst Richard Windsor, the screens, which rather than recognising pressure as in traditional passive touchscreens instead respond to heat, use a chemical layer to track contact, and it’s this layer that has been failing in a so-far small number of iPhones.  The original company who developed the technology were, apparently, looking to bring a similar concept of handset to market, but went bankrupt in the process.

Windsor maintains that Apple should be aware of, and have fixed, the problem, but the current crop of malfunctioning phones does not bode well.  Jobs & Co must be hoping that these are random, unconnected problems, and not a sign that their further touchscreen development failed to fix the issue.

Remember, we’re interested to hear if your iPhone develops problems, so leave us a comment if you’ve noticed anything unusual.

You may have read my previous report of the Synaptics Onyx Concept phone, which features many of the forthcoming touch screen technology. The LG Prada phone is the direct result of the Onyx concept phone.

“Optical sensors and touch will be the next big things,” Nokia Chief Technology Officer Tero Ojanpera said in Singapore on Monday ahead of the CommunicAsia telecom fair.

“I believe there will be a lot of innovation around these,” Ojanpera said.

The video below is a great example of the throughput rate for the new generation of touch screens with sensors.

High Tech Computer (HTC) also jumped on the iPhone bandwagon recently with its Touch phone, offering similar on-screen gesture as the Prada and iPhone.

On the other hand, the developmental history of the iPhone is a big mystery, but I’m positive this Apple fell from the same tree as the LG KE850. The purpose of this story is to share with you similar characteristics between the Onyx Concept phone, iPhone and LG KE850. It’s not my position to take sides as to whether Apple copied LG or vice versa; we’ll leave that up to the courts.

Let’s take care of the first few questions such as the screen technology. I’ll show you through video demonstration what’s being advertised and what the two devices are capable of when they grow up.

This first video demonstrates Synaptics’ ClearPad touch screen technology, a transparent touch-sensitive capacitive sensor. Far greater in accuracy than traditional passive touchscreen displays, ClearPad’s strength is the resolution and detail it captures from each touch and gesture; the video below shows the Matrix-like stream of data generated simply from swiping a finger across the screen.

The Onyx Concept phone can discriminate between one and two finger use and can even tell when it is being held against a cheek: answering the call automatically. Now while the iPhone hasn’t learned this yet, it does have a distinctly similar trait that they’re also calling the proximity sensor. This sensor detects when you lift the iPhone to your ear and immediately turns off the display to save power and prevent inadvertent touches until iPhone is moved away. It is to be seen whether the LG KE850 will have this feature. The video below features a conceptual explanation of the the proximity sensor, a demo on the Onyx Concept phone, and finally an explanation by Steve Jobs.

Now the iPhone doesn’t have a GPS (that we know of yet) but it does feature Google maps, which highly resembles the GPS system that we saw on the Onyx Concept phone. This feature is yet to be confirmed on the LG KE850.

I didn’t notice Steve Jobs demonstrating on-the-fly play list management, so the feature we saw in the Onyx Concept may be implemented down the road.

Note the incredibly straightforward way that two single calls (watch Onyx Concept videos below) are combined into a conference call, by dragging one contact onto the other, and contrast that against the convoluted menus and key presses needed on traditional cellphones.

Looking into a crystal ball, I have a rare opportunity to share with you the potential of these two handsets and future offspring. In a way we’re lucky, considering Synaptics were clear when they exclusively demonstrated Onyx to me that the first derivative consumer handset would appear in early 2007. Until the lawyers have earnt their daily crust and the phones themselves hit the shelves, we’ll just have to enjoy this three-part video walkthrough of the Onyx Concept phone and look with barely-restrained contempt at our bland Nokias, Motorolas and Samsungs.

Now we have solid confirmation that LG’s handset is based on Synaptics technology, and the UI itself looks very similar to that designed by the other side of the Onyx partnership, Pilotfish. Apple information, of course, is harder to come by, and there’s no doubting that their GUI is streets ahead. They’ve referred to it as OS X for a cellphone, and whether that’s true or more like marketing patter the bottom line is that it appears to be a naturalistic and texturally-rich way to interact with your mobile. Based on our observations, then, MYiPhone would wager that the DNA of both handsets can be traced back to Synaptics initial concept, but their personalities – the way they present each app and the ecosystem your data resides in – is most definitely a product of their adopted parents; at the end of the day, isn’t it fair to say that this is pretty much par for the course in the electronics world? Multiple gadgets, often made up of the same core technology, with the interface as their distinguishing factor. On those grounds, Apple – while maybe not the hardware trailblazers here, have nonetheless seized the upper-hand.
