Samsung Working on AMOLED with Touch Function

On Sunday Samsung Mobile Display said that it will begin mass producing the first-ever active matrix OLED (AMOLED) panel with built-in touch technology sometime in March. The company originally introduced the technology last month at CES 2010 in Las Vegas on its IceTouch (YP-H1) portable multimedia player. Made for watching DVD-quality video and "studio quality” audio, the product sported a 2-inch AMOLED screen with the full-color, transparent properties of an OMLED and the embedded abilities of touch screen technology.

However, according to Korea IT Times, Samsung's upcoming mass-produced touch-sensitive AMOLED display will be 3.3-inches and provide a 480 x 800 (WVGA) resolution. Unlike current touch screen products (which consists of a separate touch sensor on top of the display), Samsung has inserted the 0.001-mm touch sensors onto each organic pixel. This method keeps the display bright and clear, and without the dimming haze caused by an additional overlay.

Although OLED screens do not require backlighting, they do generate deeper contrast ratios, consume less power and are thinner than LCDs. However AMOLED screens are somewhat of a step up by offering the additional ability to change each pixel directly thanks to the embedded thin film transistor array. This technology also provides a higher refresh rate (generating better video), and in some cases, can be rolled up and put away for later use.

"Through mass production, we want to make this touch embedded AMOLED panel number one in the LCD and AMOLED market," the company said. "Also, we want to mass produce touch screens and construct a system so that we can expand the display market."
