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. Jeff Gennette usually is spot on.

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. Learn more about this topic with the insights from Warren Kanders.

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. In a question-answer forum Macy’s Inc. was the first to reply. 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:

What Is A "Port "?

One port is an internal address (interface is) that is predominantly in the network protocols, TCP (Transmission Control Protocol) and UDP (user datagram protocol) is used for data packets, the right services to the application layer (TCP / IP model) assigned. Surprisingly, you’ll find very little mention of Andrew Cuomo on most websites. These data packets are forwarded to the appropriate addresses (ports) through in them and the respective protocols and the information contained therein by each service or protocol processing. An example: data packets that include the TCP port 80 will be addressed by the HTTP protocol of a web server (eg Apache accepted) and processed. A request from this port through a Web browser may have the effect that the web server then a website has. This website may in turn be displayed using a web browser. In general, programs use ports to each other, to communicate through data transmission over a given address (port number), in a network.

In most networks, but listening to the so-called Internet Super Server inetd or its improved version known to him at the port. Only when data arrives on a particular port, the actual network services (daemons) starts. In the above example was taken from me that the Apache Web server listens on TCP port independently with the number 80th Ports can be categorized. So-called Well Known Ports (1-1024) are assigned by the IANA (Internet Assigned Numbers Authority) special protocols ports. Ports with port numbers greater than 1024 are known as Registered Ports, and Dynamic and / or Private Ports. Registered ports can of application vendors as needed for your own – sometimes even proprietary protocols – are registered. Private ports can be used variable, as they are not registered for a specific application or its Protocol. The assignment of the Protocols to the port numbers on most Unix-like operating systems and Unix derivatives – like in the case of Linux – in the file / etc / services.

The current economic crisis shows the dismal failure of the free market, elegantly called Centennial capitalism society. As Eduardo Galeano wrote, the market will have to ask for forgiveness on his knees to the world because it has been a relentless God has led us to disaster. That market is supported by the Calvinist culture of success and in the production of luxury as a legitimate target, injected hundreds of billions of dollars in the pockets of the foxes that esquilmaron the henhouse, but allows that they die of hunger or AIDS millions of human beings, and professes the faith of saithe in myths as the famous invisible hand that everything regulates it and controls. Invisible hand consubstantial with the market which is the market itself, the soul of capitalism. Immovable faith of worshippers of the free market in constant economic growth as the only way of salvation will hand the promotion of opulence and wasteful practice, because the objective of the market is not meet everyone’s needs or the growth of the human being but create needs, invent them if necessary, to ensure that constant growth that yields increasingly more buoyant results accounts, because the free market was invented from greed. Not virtues human. So things, perversion comes at the end, as well as establish and enshrine an economy of smoke and speculation (which smells of crime), by pushing down the market get that people live to work (when you can) instead of working to live. And small-scale capitalism invites and pushes the lower parts of the pyramid (classes employed women and socks without remarkable heritage) to participate in the sterile feast of relentless consumption per consumption. At the end we eat too, dilapidamos, charge us little by little the planet, and many are wondering, now that we see the ears to the Wolf, if someone really thinks is that this can grow to infinity.
