• Foldable Mobile Phone Display


    Now launched, foldable smartphone display technology will alter the users’ mobile phone experience endlessly.

    Whether it is Royole or Samsung, all mobile phone manufacturers were indecisive of mass production of high-tech smartphones with a flexible display.

    But, with the beginning of 2019, foldable smartphones like ZTE Nubia phone, Royole FlexPai, Xiaomi ‘Dual Flex’, Huawei ‘Mate Flex’ and Samsung Galaxy Fold are all ready to confiscate the market like never before.

    Back in 2018, notch display was something that dominated discussion forums in social media and other platforms.

    While in 2019, the foldable or flexible display seems to take the same responsibility soon.

    Fortunately, all students from the Best Mobile Phone Service Training Institute In Kerala i.e. IASE (Institute of Advanced Studies In Engineering) are well acquainted with the nitty-gritty of foldable mobile phone displays.

    Like every other technology trend, the cost of foldable smartphones is also expected to come down.

    On the date of Galaxy Fold launch, Samsung confirmed the cost of their revolutionary smartphone to be $1890.

    But a recent CIMB study corroborated that the cost of a foldable smartphone is foreseen to come down to nearly $1300 by 2022.

    While for the same year 2022, another market analyst firm DSCC affirmed that market demand for foldable OLEDs (organic light-emitting diodes) will be elevated from 3 million units in 2019 to 63 million units in 2022.

    AMOLED displays revenue in 2017 was $26.4 billion, while a 7.1% hike in the same has been observed with the revenue of $28.3 billion in the financial year 2018.


    We’ve been hearing about the flexible display revolution for years now. So, where are they?


    Even Royale’s impressive flexible colour display with a 0.01-millimetre thickness and less than 1-millimetre rolling diameter that was unveiled way back in 2014, still hasn’t appeared in a fully flexible commercial product.

    As Dr.Bill Liu once said “A high investment area and no one has experiences out in products for flexible displays yet. Because no one is making enough of them.

    There are many different materials, semiconductors, conductors, insulators and barriers that you have to combine into a very thin film.”

    If you change a single material, you probably have to change other materials as well, to make everything compatible. So, it’s not just one single innovation and that makes sense.

    But, he also claims that it’s not only the materials. It’s the corresponding processes, device design, circuit design and product design, all that is new also.


    The reason what stopping flexible displays from taking over is its volume. Volume is key.

    Although manufacturers have been really interested in flexible displays, if you don’t have large volumes, even if the technology is very interesting, they can’t take a risk on a new project.


    It’s not all about foldable displays either, folding and unfolding is just a first step, in the future, you’ll be able to roll displays like a pen and unrolled it to have a much larger screen.


    But, at present, in the news is ‘Samsung launches its Galaxy Foldable smartphone with a seamless continuous display.’


    Probably it was consumer reaction which postponed the launch of Foldable smartphones. Otherwise, LG launched rollable OLED TV way earlier, which in technology side is more advanced than foldable smartphone technology.
