Bendable & Flexible, Concave & Convex, OLED & LCD UHD TVs by Samsung, LG and Panasonic at CES 2014

Every year Samsung, the world’s largest maker of TVs and LG, world’s 2nd largest TV manufacturer, surprise consumers with new TV technologies or screen sizes.

At CES 2012 they both were the only companies to exhibit 55” OLED TVs.

At CES 2013 they both were the only to show 55” Curved OLED TVs.

At IFA 2013 exhibition in Berlin Samsung and Sony presented “World’s First” 65” Curved LCD TVs.

So that customers got lost trying to compare LCD and OLED, Flat and Curved, Full HD or Ultra HD. Many of them couldn’t understand why somebody decided to manufacture Curved OLED or Curved LCD TVs while Flat LCD TVs are OK for home?

At CES 2014, as you might guess, both Samsung and LG delivered another new technology combination: Bendable TV, as Samsung decided to call it, or Flexible TV, as announced by LG.

LG unveiled “World’s First 77” 4K Flexible OLED TV” that can change its screen shape from flat to curved and back by pushing a button on a remote control.


If you look from the side you will see the range between “Flat Screen” and “Curved Screen” position.


Samsung put on its booth four OLED TVs under the header “Bendable OLED TV” not specifying the size, because it is “standard” 55-inch and not saying whether it is Full HD or Ultra HD.


It is possible to see the range between flat and curved shape. You never might imagine that TV can change its screen shape like fighter jets change its wings shape.


In order to differentiate further, under the big header “Samsung’s First to the World Innovation Technology” Korean conglomerate placed “Bendable UHD TV 85”


It is a real challenge to produce a bendable LED TV prototype but they could manage to do it for CES!

This is a curved shape view:


Since Panasonic put stress on B2B, not on B2C solutions, instead of concave bendable or flexible OLED TVs it exhibited 4K OLED Video Wave consisting of 3 convex and 3 concave 55″ OLED displays based on its printing technology.


It’s hard to imagine what would be the next? Just wait for the CES 2015 when the new dreams of Korean and Japanese engineers will become visible.

Sharp shows OLED displays with IGZO backplanes to visitors of Consumer Electronics Show being held in Las Vegas, Nevada, USA, from January 8th till January 11, 2013.

These displays were first exhibited at Flat Panel Display International exhibition in Yokohama, Japan (Oct. 31 – Nov. 2, 2012).  The displays have been developed jointly by Sharp and Japanese R&D company Semiconductor Energy Laboratory (

The first OLED display has 13.5 inch diagonal and QFHD (3840×2160 pixels) resolution while the second display is flexible with 3.4 inch in size and 960×540 resolution. Both panels have pixel density of 326 pixels per inch (ppi).

These two displays use IGZO TFTs for the backplane and white OLEDs with RGB color filter in the front plane.
