Lianjian Optoelectronics said that after the company acquired the outdoor advertising professional agent time-sharing media in 2014, the linkage culture will serve as the national media landmark outdoor LED advertising network. It will be used as a media platform for the network. Media's mature sales team, management model and customer resources, expand and enhance the advertising sales business of the network. In April, Timeshare Media has signed advertisements for Dongfeng Citroen and FAW Mazda for the network. It is expected that the advertising sales business of the network will be improved quarter by quarter. In order to turn the linkage culture into a profit in 2014, the linkage culture will no longer affect the company's 2014 consolidated statement profit.
On the same day, Lianjian Optoelectronics announced the first quarterly report for 2014. In the first quarter, the company achieved a total operating income of 131 million yuan, a year-on-year increase of 0.73%. The net profit attributable to the company's common shareholders was 4.803 million yuan, an increase of 16.67%.
The Schottky Diode is another type of semiconductor diode which can be used in a variety of wave shaping, switching and rectification applications the same as any other junction diode. The main adavantage is that the forward voltage drop of a Schottky Diode is substantially less than the 0.7 volts of the conventional silicon pn-junction diode.
Schottky diodes have many useful applications from rectification, signal conditioning and switching, through to TTL and CMOS logic gates due mainly to their low power and fast switching speeds.
the Schottky Diode also known as a Schottky Barrier Diode is a solid-state semiconductor diode in which a metal electrode and an n-type semiconductor form the diodes ms-junction giving it two major advantages over traditional pn-junction diodes, a faster switching speed, and a low forward bias voltage.
The metal–to-semiconductor or ms-junction provides a much lower knee voltage of typically 0.3 to 0.4 volts compared against a value of 0.6 to 0.9 volts seen in a standard silicon base pn-junction diode for the same value of forward current.
Variations in the metal and semiconductor materials used for their construction means that silicon carbide (SiC) Schottky diodes are able to turn [ON" with with a forward voltage drop as little as 0.2 volts with the Schottky diode replacing the less used germanium diode in many applications requiring a low knee voltage.
