The FPD International 2008 starts and we have the first OLED innovation from Samsung. The Flapping OLED Panel!
Samsung SDI Co Ltd exhibited a 0.05mm-thick 4-inch OLED panel that was hung in the air and fluttering in the breeze from a fan at FPD International 2008.
The pixel count of the display is 480 × 272. The contrast ratio is 100,000:1, and the luminance is 200cd/m2. The color reproduction range is 100% of the NTSC standard.
It is technically possible to make the panel thinner,” a Samsung staffer said. “However, it is difficult to further reduce the thicknesses of the flexible substrates and circuit components around it.” That’s why the company set the size at 0.05mm.
To achieve this thickness, Samsung etched 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.
