Oled or Lcd? Hypotheses on the screen of the Apple tablet

logomacitynet1200wide 1

Screen, screen of my desires, what will the Apple tablet be like? The question is not addressed to the mirror of the witch but to the Asian producers of 10-inch screens. That, according to the usual anonymous sources within the sector, they would no longer have LCD or Oled panels available because Apple would have grabbed them all.

Although this umpteenth "rumor" from Asia is intriguing and only adds weight to the idea of ​​the size that the Apple tablet, of which the company has not yet even admitted the hypothesis that there will be a presentation on 27 January as it is believed, in reality there are other more interesting questions. Because the "voice" supports too many things.

Lcd and Oled panels are very different not only in technology and yield, but also in industrial cost. In fact, used on cell phones and other devices up to Microsoft's Zune, on a 10.1-inch screen product that costs a thousand dollars they would have the harmful effect of making it produce practically at a loss, even by purchasing large quantities in stock. And as we all know, Apple does not produce anything that then goes on to sell at a loss.

Instead, a more consistent and coherent hypothesis also with the problems that have always emerged from "rumors" in recent months, it is more likely that in case an Lcd panel with Ltps technology is chosen, ie Low-temperature polycrystalline silicon, used in televisions and screens more modern and highly predisposed not only for the yield but also for the specific characteristics to be integrated with an LED integration system. The latter could be the trump card for a device that should count on a robust battery life and at the same time on a minimal thickness, as Steve Jobs usually claims from his engineers.

If you see the work that has been done in recent months by the manufacturers of television sets such as Samsung and LG, you can see that the super-thin models (and we are talking about an inch or less for a TV!) Have used exactly this combination of technologies, which also have the advantage of significantly reducing the electricity bill, the real Achilles heel for owners of LCD televisions with "normal" technology above 32-40 inches, as regular users of these devices know well.

The basic problem remains the one that emerged a couple of times from the valley of the deep gorges and that the writer finds intriguing: the delays in the presentation and marketing of the appliance, which ideally should have arrived in the winter and not in the summer , as it might be presumed to happen, they would have depended in the first instance on the "idea" problems that Steve Jobs himself had deeply criticized returning to work after his transplant that kept him away from Cupertino's desk for seven months. But also, after finalizing the mysterious "form factor" of the mystery tablet, from another problem.

The ballet of technologies and suppliers to which we have been exposed and then bombarded in recent months certainly to be understood as due to a double reason: on the one hand there has been overlap between different projects and perhaps also different devices (that is, the tablets prepared and then discarded from Jobs and also the jobs for the next generations of iPhone and iPod touch, in addition to the screens of MacBook and iMac). On the other hand, there was the problem of being able to find the subcontractor that produced what Apple wanted and that the most intriguing part of the little or nothing we know about the tablet. That is to say the idea of ​​a super-robust screen capable of supporting the "load-bearing structure" of the object.

Put from another point of view, if we take for example a phone like the iPhone, we notice that the edges are resistant and relatively abundant to protect the glass and support it on a frame. By keeping it in your pocket and so on, in fact, part of the weight is downloaded directly onto the 3.5 inches (equal to 8.9 centimeters) of the screen. That always exposed. The thinner the appliance, on which the weight of the person or other is likely to rest vertically, the more robust the frame and the glass itself must be (thicker and more resistant). And the same, if it falls or is hit or otherwise sits on the glass, the risk of a very strong break. Here, let's imagine the same thing for a similarly shaped device, very thin and with 10.1-inch diagonal glass, equal to a diagonal of about 25.65 centimeters.

This simple rumor that Apple has struggled to find a manufacturer with the technological processes necessary to make a glass so resistant as to withstand the stresses of a 10.1-inch screen says a lot about the difficulties and how ambitious Apple's work is and his engineers. And how surprising will be the solution that was probably found.
