In light of growing demand for Samsung Display's flexible AMOLED technology, the company has recently released reports regarding some of its latest flexible display technology used in new Galaxy S6 Edge models and has also announced it will continue to evolve from curved, to bended, foldable and even rollable designs.

Flexible AMOLED substrate material

Samsung Display's Flexible AMOLED uses polyimide (PI), an advanced type of plastic, as the substrate material rather than hard glass used in rigid AMOLED panels. PI is a high polymer material with characteristics of exceptional flexibility, resilience and shock resistance. Samsung has been able to make an extremely thin film out of it - less than a millimeter thick (thinner than a human hair). With the thickness of the AMOLED substrate being less than half the thickness of glass substrates in conventional mobile LCD displays, Samsung has been able to deposit an electronic circuit onto it and evaporate a luminant RGB organic device, making it potentially more bendable than a human hair.

Picture clarity

Samsung's flexible AMOLED delivers Quad HD picture clarity at 1440 by 2560 pixels with a pixel density of 577ppi. It can deposit more than 3.6 million RGB organic subpixels on its PI substrate, allowing the user to see fine image detail.

Power use

The flexible AMOLED display can drive each of its pixels individually. This helps it to reduce power consumption. Its pixel control allows for the use of "partial operation technology" permitting a smartphone to make use of only 7mm of each column of the curved display at any one time -- therein reducing power consumption today by about 20% and possibly more in the future. Comparatively, note that in an LCD mobile display, a simple widget or pop-up message uses the entire backlight unit to illuminate the screen.

Finger Aid

As the average size of a smartphone increases, when a consumer uses only one hand to access data, his or her finger muscle can become fatigued when accessing touch menus or icons placed on the upper part of a screen. In general, potential problems with smartphone-related conditions, such as "Dequervain Syndrome", caused by straining a finger muscle and wrist, can be minimized by the use of curved displays.

Edge displays have been optimized to achieve the greatest amount of user convenience on the market today. Consumers can move the icons and menus that they most frequently use to an Edge screen so that their favorites can be easily touched with just one hand, reducing finger fatigue by as much as 20 times over, said Samsung.
