In a few years is once again the TV / monitor market up again. The display next generations are already in the starting blocks. SED (Surface-conduction Electron emitter Display) This technology is developed by Canon and Toshiba, and consists of conductive electron emitters. SED displays are similar to a cathode ray tube. But instead of a single electron-emitter an SED is working with one emitter for each subpixel. The big advantages of SED technology are the low power consumption, and the high angle.
The contrast / color brilliance, and the reaction time is on the SED technology is also sensational. Recently introduced Toshiba / Canon SED before a television with 450 nits brightness and a contrast ratio of 50,000:1! Response time 1 ms. Toshiba and Canon to 2008, the mass production of flat panel displays according to the standard SED include OLED (Organic light emitting diode) The paper-thin OLED displays promise, energy-efficient monitors. OLEDs are already being used in various products. Displays made of organic light emitting diodes (OLEDs) are flexible, thin, energy saving and provide brilliant meter reading properties.
They open up new application areas: as a large-area lighting, TV screens or mobile phone displays. However, before storming the OLEDs the mass market, there remain some problems to fix.OLEDs based on organic semiconductors that glow when power is applied. A distinction is made in small molecules (small molecules / SM) and long-chain polymers. Mid-80s represented the first time a researcher from Kodak OLED manufactures of small molecules. Shortly afterwards Cambridge Display Technology, OLEDs from Polymeren. The structure of an OLED display is compared to an LCD very simple: a glass or transparent plastic base film, a transparent conductor of electricity is applied, this is usually indium tin oxide, which later in the component as anode acts. The carrier is then a thin film of the plastic-coated phosphor. Finally, a metallic cathode is deposited. It was only recently introduced a Samsung SDI 17 OLED Display. Samsung SDI AMOLED presents with 1.2 mm depth! Thus, the display offers a maximum resolution of 1600 x 1200 pixels on a diagonal of 17 inches a brightness of 400 candelas per square meter and a contrast ratio of 1000:1. The maximum angle is 170 degrees, can the reaction rate at 0.01 ms – a value that dream of the current LCD or plasma devices only. Samsung SDI will start in January 2007 with the AMOLED mass production of 2 inches to 2.7 inches. In my opinion, the SED technology is earlier than 2008 can compete in the market (price / performance). The OLED technology needs to work on the life and will be eligible for larger displays on the market earliest in 2010. More information about the OLED and SED technologies:
