Bendable or flexible screen displays are getting to be the next big thing with digital devices having the capability of being folded, not just curved. Over the years, there has been quite a lot of excitement about the release of bendable displays. Their mass production is greatly anticipated, partly because of their durability, particularly their indestructible qualities. In this article, you will be given an overview about how bendable screens and displays work.
WHAT ARE BENDABLE DISPLAYS?
In case you haven’t worked it out yet, bendable or flexible displays are those screen displays that are fully bendable or flexible, meaning unbreakable and durable even when purposely and constantly flexed or bent. Production of flexible screens have been announced as early as 2012 and it’s an anticipated, exciting development in screen or display technology which carries significant advantages in addition to its superbly cool features.
BENDABLE DISPLAYS – HOW DO THEY WORK?
The greatest problem encountered so far in making flexible screens was glass. This material doesn’t bend, it’s thick, heavy, and breaks easily. Bendable displays largely rely on existing technology commonly known as AMOLED (active matrix light emitting diode) or OLED (organic light emitting diode).
Traditional AMOLED screens usually use organic compounds that create their own source of light when current is quickly passed through them. As OLED pixels create a light source of their own, they don’t actually need an additional back light like that of LCD screen technology, but the circuitry controlling the pixels is necessarily fused into glass. Bendable displays simply replace those layers of glass of the LCD with layers of (bendable) plastic film, thus allowing the screen or display to be bent without breaking anything.
PROS AND CONS
a- Advantages of Flexible displays
There is already a great screen technology – 1080p as well as AMOLED screens impressively under 5” with an incredible pixel density viewable only through a microscope. Does it really have to be any more impressive than this? Do you really need a bendable or flexible screen?
Well – probably no, you may not actually need one. But you may have several reasons why you would want one. Because it turns out now that you’ll find it a huge advantage not to use glass, as follows:
1- Slimness – With no more need for bulky and breakable glass, bendable displays are now significantly slimmer, resulting to the thinnest screens or displays you’ve ever seen.
2- Weight – Without glass, bendable displays are also significantly lighter.
3- Durability – Without the presence of breakable glass, bendable displays are quite invincible to the usual bumps and drops you inflict on your prized devices.
4- In the long-term, bendable displays should be cheaper – Perhaps not in producton but the relative lightness and thinness of bendable displays means more of these items can fit into just one shipping container. That would mean cheaper to ship hence (in theory) cheaper to buy.
5- THEY ARE FLEXIBLE!
b- Disadvantages of Bendable Displays
Although it has been cited that “durability” is one of the PROS or advantages of the new FAMOLED displays, it could actually be considered as a possible cause in the the bendable technology’s downfall. With four layers of components plus a protective casing endlessly bending around, you are likely to observe some wear-and-tear after a while. One advantage of using glass in encapsulating thin-film transistors and other pieces of technology is that it effectively keeps the screen circuitry from moisture or dirt which might possibly sneak in somehow. Plastic is certainly not as good at preventing moisture to seep in as glass is, more especially if faults begin to appear after constant and excessive folding. This is probably one of, if not, the main reason in the delay of its release, but recent development such as �100,000 fold FAMOLED” have floated around recently – suggesting that bendable display technology is already durable enough to resist and survive constant day-to-day flexing.Read More
