Samsung’s ‘Flapping’ OLED

Remember Sony’s ultra-thin and curvy OLED panel earlier this month? Well, guess what? Samsung has a similar thin OLED in the works called the “Flapping display.” Showcased at this year’s FPD (Flat Panel Displays) International Exhibition, Samsung boasts that the 4-inch, 0.05mm thick OLED panel has a resolution of 480 x 272 pixels, contrast ratio of 100,000:1, and a luminance rating of 200cd/m2. Samsung also states that the Flapping display is capable of reproducing color 100% within the NTSC standard. Appearance wise, the display looks like a piece of laminated plastic.

To get the Flapping OLED as thin as it is, Samsung had to:

…[etch] an OLED panel that uses a normal glass substrate. The drive circuit was formed by low-temperature polysilicon TFTs. Also, low-molecular organic EL materials were employed.

The panel was not sealed by a glass substrate but by membrane sealing technology using a sputtering method. That’s why the 0.05mm thickness is almost the thickness of the drive circuit board.

In other words, it’s basically a super-thin glass panel wrapped around a thin and flexible membrane, allowing it to ‘flap’ in the wind.
