Folding iPhone Patent Application Shows How the Company Could Prevent Damage In Cold Weather (appleinsider.com) 51

A new patent application from Apple, titled "Electronic Devices with Flexible Displays," describes how the company could prevent foldable smartphone displays from getting damaged in extreme temperatures. "While at or in the region of typical temperatures hospitable to humans, folding systems may work fine, but adhesives and other elements used in a device's production may become more resistant to flexing at cold temperatures, which could cause unwanted wear or damage to the display if attempted in such conditions," reports AppleInsider. "To mitigate the cold temperature, Apple simply suggests there should be some way to warm up the area of the display panel where the bend takes place." From the report: As part of Apple's solution, an onboard temperature sensor is used to determine how warm the device is, and whether or not there is any danger to allowing the screen to be flexed by the user. The warming process itself can be performed by a heating element located near to the section that bends the most, with heat conductors transferring the warmth to where it is required. A heating element may not be practical to add to such a device, which has led to Apple suggesting an alternative, namely using the heat generated by illuminating the screen. To do this, a screensaver could be used that concentrates most on the bent section, such as by making it brighter and lit up more than the rest of the screen.

As the heating process could take time to complete, Apple notes there is a danger of the display being flexed before it is safe to do so, something it has also considered. Aside from warning the user on an attempt to bend, Apple believes the use of a latching mechanism to keep the device closed while folded may be worth investigating, both as a mechanical latch and by the folded device being held shut by magnets. When the temperature of the area is relatively safe, the latching system can be disengaged and the user will be free to open the device once again. The patent application does not seem to answer the question of how to prevent the user from folding up an unfolded device, but it could be feasible some form of locking mechanism could be used when the smartphone is flat.

      I'm pretty sure Apple will invent foldable screens any day now.

        With rounded corners and a courageous lack of audio jacks! In fact, forget the foldable screen.

      Sorry to rain on your parade but Apple is buying these bendy-screens from either Samsung, LG or both: https://9to5mac.com/2018/09/14... [9to5mac.com]

  • A little bit of heat makes things move easier. They haven't detailed a novel method of applying and controlling such heat relative to the application. It looks like nothing more than trying to patent a simple feedback loop. Seems obvious.

      And somewhat impractical as a solution. Resistive heating is power intensive. When your phone shuts off due to low battery, how will you know to not open it?

    • It's patently obvious.

      You'll often find Apple patents for highly specialized fields for which the experts work at competitors, which just try to patent little practical corner cases which they might not yet have thought of. They clearly employ people specifically for this, not doing research ... just being Apple's personal patent trolls, building up their patent war chest.

  • People have wondered how folding screens (particularly exterior folding screens a la the Huawei Mate X) are going to be protected. Glass doesn't bend very well at the hinge part, which means plastic has to be used. However, plastic that bends well tends to be soft and thus scratches easily. My sneaking suspicion is that this calls for a 'new' tech I read about here on Slashdot 11 years ago [slashdot.org]. In particular, bonding plastic, which covers the hinge, to glass that covers the rest of the screen. Sure, the hinge a

    • That's why every other company making a folding screen has put it on the inside. The press is currently going gaga over Huawei's folding screen, but they tend to be extremely short-sighted and overly concerned with appearance. I'm curious to see where they'll stand after using it for a year, when the screen will be all scratched up because it's made of plastic, is always on the outside, and can't be protected by a screen protector because of the fold.
  • That's an idea that never should have crossed their minds. You don't need a heater anywhere near your chips, you just nee to put them under load. Crank up the clock for a minute and have it do something. If a screensaver can do it, good, but I've never noticed my screen getting warm on its own. Battery and CPU, oh yeah.

    Point being, radiating waste heat is a problem for phones; not being hot enough isn't, for the same reason.

    Maybe if Apple didn't glue everything shut to protect it from repair or replacement, this wouldn't be such an issue ...

  • Adding the phrase "on a folding phone screen" does not make the concept of heating cold-sensitive parts worthy of a patent.
    • by labnet ( 457441 )

      Exactly. If you told any engineer, the fold is damaged in extreme cold, then the first response would be put a temperature sensor in it and heat it. Not worthy of a patent.

The rule on staying alive as a program manager is to give 'em a number or give 'em a date, but never give 'em both at once.
