Samsung Electronics announced that it developed the largest single-panel, active-matrix-based (AM) Organic Light-Emitting Diode (OLED) display.

At 21-in, the OLED is said to feature the highest resolution at 6.22 million pixels (wide ultra-extended graphics array or WUXGA). In addition, the company adopted AM-based technology for low power consumption and high-resolution qualities.

The new OLED offers brightness of 400 nit, contrast ratio of 5,000:1, color gamut of 75 percent, and fast response times, making the product ideal for viewing HD-resolution video images, Samsung said.

The OLED uses Amorphous Silicon (a-Si) technology, and can be mass-produced within Samsung's existing TFT-LCD lines. The company has now applied the a-Si technology to produce large-sized OLED panels within fourth and fifth generation production lines.

"With the development of the world's largest OLED at WUXGA resolution, Samsung has achieved a technological advantage and is positioned well to be a leader in the large-sized OLED for the TV market," said Jun-Hyung Souk, senior vice president of Samsung's LCD R&D Center.
