Samsung's new QVGA OLED display finally goes into mass production, which could lead to a breakthrough for OLED displays in mobile phones.
Until recently, mobile phones with large OLED displays have been scarce, one of the few exceptions being Nokia's 7900 Prism. But today Samsung has confirmed mass production of Active Matrix OLED displays for mobile phones and other handheld devices, and it could be only a matter of time before this type of display is a standard feature on high-end phones.
Samsung's new AMOLED display supports QVGA resolutions (240 x 320 pixels) and is capable of producing a range of over sixteen million colors. The AMOLED display is a self-luminous device that works by having electrical current flow between two thin layers of organic film. This allows for designs that are lighter and thinner than allowed by other display types. Images are shown at the speed of light, so they are supposed to look natural without the ghosting effects seen in such fast-paced video sequences as sport events.
These characteristics should contribute to an improved video call experience, and phones supporting TV streaming via MediaFLO would also benefit greatly from such displays.
Samsung's new 16M-color AMOLED displays self-adjust the screen's brightness, illuminating only those areas that need light. As a result, power consumption is minimized and battery life extended - a key issue in recent years. The read-only memory (ROM) is built in separately, enabling red, blue and green (RGB) gamma compensation to reproduce more lifelike images.
According to the market research firm Display Search, the global AMOLED market is expected to reach 7.82 million units in 2007 and increase to 127.71 million units by 2011, for a compound annual growth of 101 percent.
