Personal computer humanity dreams to get rid of excess wires. Today the producers achieved a great success in this direction: interfaces for monitor connection already transfer sound and image simultaneously, and Intel company proposes to replace all interface cables by one optical information circuit light peak. The exchange of information between the devices can be accomplished on the wireless networks, and some notebook can be even charged without wires from the special dock- station.
Samsung company takes many efforts to make only cable for the connection of the monitor to the computer. Samsung company demonstrates the model of the monitor, which obtains on the interface USB picture, and power.
The prototype of the uncommon monitor uses economical light-emitting diode and TN matrix, which after adaptation reduces the energy consumption level to 6,3 W. Monitor has the screen diagonal of 18.5 inch it supports the resolution 1366 X 768 pixel, it is characterized by the brightness 250 cd/sq. m and contrast 1000:1. The demonstrated by company monitor obtain power from two USB 2.0 ports. Samsung promises to start the production of such monitors in 2011.
The USB 2.0 standard prescribes a limit on the current strength on USB ports with the value of 500 mA. USB voltage is also limited by five volts. It turns out that maximum required power connected to the USB port is equal to 2,5 W. Even with the connection to two ports USB 2.0 device can not collects six watts declared by the company. Let us note that USB 3 0 ports. maintain current strength up to 900 mA.
In order to understand, how samsung monitor work, it suffices to study last statements of MSI and ASRock. They explained following gigabyte company that their motherboards can maintain on the USB ports higher strength, than standard. With the connection of iPad the strength rises to 1,2 a. in order to attain this, it is necessary to install a special driver, which will raise strength to the necessary value. Most likely, samsung monitor work according to analogous diagram. Related Products :
