Samsung Display Discuss their Most Advanced Flexible AMOLED Display as used on the Galaxy S6 Edge

Samsung Display is a global leader in the design of displays and the largest manufacturer of both OLED and LCD display panels in the world.  They recently released key details about its new Flexible AMOLED display – it is not only the most advanced in the mobile industry, but you can now get one on the new Galaxy S6 Edge smartphone with dual curved edges.  Ho Jung Kim, a spokesperson for Samsung Display said, “We are witnessing enormous interest in our leading-edge Flexible OLED display, even more than had been anticipated.  We are working extra hours to increase our production levels in order to meet the extremely high demand.”  When Samsung launched the new Galaxy S6 and Galaxy S6 Edge, they naturally thought that the original Galaxy S6 would outsell the more costly Galaxy S6 Edge, but recent reports have shown that they are selling equally well and putting a strain on inventory of curved displays.

This flexible AMOLED display is actually the third rendition in Samsung’s quest to increase the quality of their flexible displays.  In October 2013, Samsung Displays massed produced their first display using the world’s first flexible AMOLED (Active Matrix Organic-Light-Emitting Diode) in a curved smartphone called the Galaxy Round.  It was curved from right-to-left and never left the Asian market area.  Last year, Samsung introduced us to an improved technology called the YOUM Bended Display and it debuted on the Galaxy Note Edge.  It had only one side of the display curved downward and it acted as a second display, independent from the main display.  But it was actually one display, separated through the software running the display.  The newest development is called Flexible AMOLED Display and is Samsung’s next major advance in design and introduced as a dual curved display on the newest Galaxy S6 Edge.  Samsung says that these flexible displays will evolve into bended, foldable and eventually a “rollable’ design.

The substrate material used the flexible displays is a polyimide (PI) – an advanced plastic rather than hard glass used in rigid AMOLED panels.  Samsung was able to make it into a film, thinner than a human hair, and yet still able to deposit an electrical circuit on it and evaporate a luminant RGB organic device, leaving it more bendable than a human hair.  This new flexible AMOLED display can be used in a ‘dual-faceted’ display with two sides rounded or a single edge.  A recent study shows that most people use their right thumbs to search for information on their smartphone and the curvature of 6.5R on each side make it easier to grab the device and operate it with one hand.

The flexible AMOLED display delivers Quad HD picture clarity at 2560 x 1440 pixels and a pixel density of 577 pixels-per-inch (PPI) – the highest resolution currently available.  By depositing more than 3.6 million RGB subpixels on the PI substrate, the Flexible AMOLED display has 75-percent more pixels than a Full HD (FHD) display, as the one used on the Galaxy S5.  Because the Flexible display can drive each of its pixels on an individual basis, it helps to reduce the power consumption, easing drain on the battery.  The QHD AMOLED display can depict almost 100-percent of Adobe RGB, while the LCD technology can only replicate about 70-percent.  The Flexible AMOLED display has a response speed of 0.01ms and can deliver images up to hundreds of times faster than a mobile device with an LCD display and 8ms.

The new Samsung Flexible AMOLED display has many advantages over LCD displays and solid AMOLED displays.  They offer the best picture clarity, use less power, have full color richness and offer faster speeds for watching movies or playing games.  It is amazing where these displays may take us in the very near future.
