From Plasma to LCD, and LED to touchscreen, the display screen technology has come a long way in the past two decades. Undoubtedly, mainstream companies such as Nokia, Samsung and Apple have contributed a lot towards innovative technologies to enhance the user experience. Not to forget, the invention of active-matrix organic light-emitting diode (AMOLED) displays in 2008 that is acting as the basis for next-gen devices. Building upon this technology, Samsung and LG rolled out their curved-screen smartphones in 2014. This launch has fuelled Samsung’s ambitions to release infold, outfold, rollable and stretchable AMOLED displays. Notably, Apple has patented designs of rollable smartphone which folds like an ancient scroll.
Let’s dive a little deeper into the flexible screen technology, which seems to conquer the future soon.
Flexible Display Technology...
Literally, a flexible display screen is an electronic visual display which is movable in nature. This is a type of OLED that has a flexible plastic substrate on which the electroluminescent organic semiconductor is deposited. Or, in layman’s language, a flexible screen is a display made up of flexible materials like plastic instead of traditional rigid glass. Unlike the prevalent traditional flat-screen displays that are used in the majority of electronic devices, the flexible screens will be bendable.
• Better longevity: As these displays will be made out of plastic, they might offer more longevity as compared to the traditional glass.
• Lightweight: As it is a known fact that plastic is lighter than glass, flexible display screens will be definitely lighter than the traditional glass displays.
• Leaner dimensions: The flexible display screens have the capability to be manufactured in thinner dimensions and different shapes unlike the traditional rectangular screen.
• Unbreakable: There might be a possibility to incorporate unbreakable plastic into the flexible display screens.
• Inflexibility of circuit board: There are a lot of things going on with a flexible display. There are many different materials – conductors, semiconductors, insulators, substrates – that can be combined into a very thin film.
• Less reliable: As there is a flexible plastic substrate on which the electroluminescent organic semiconductor is deposited, there might be incidents of accumulation of screen diodes on the foldable portion of the screen after a long span of wear and tear.
The flexible smartphones by Samsung, including Galaxy X or Galaxy F, will feature two inside panels with the foldable technology and one outside panel. On being unfolded, it will have a 7.3-inch screen. Also, the technology giant plans to roll it out at a cost ranging from $1850 to $2000. Apart from Samsung, Huawei is also rumoured to be launching smartphones with flexible screens in early 2019. Moreover, the company is said to launch these smartphones with flexible screens at a competitive price, thus giving an edge to Samsung.
While a lot of talking has been done about flexible display screens, those with a soft corner for technology can’t wait for long to bend and stretch their smartphones or have a laptop-like experience on their mobile devices!
