Samsung and LG compete fiercely on OLED patents

According to statistics from the Korea Intellectual Property Office (KIPO) as of June 20, Samsung and LG's OLED patent applications accounted for 54.2% of all OLED patent applications, of which Samsung took the lead, accounting for 32.7% of all OLED patent applications. Or 2,350 applications, followed by LG, accounting for 21.5% of all OLED patent applications or 1,541 applications.
In addition, according to statistics, as of the end of April this year, Samsung and LG also ranked first and second in the number of all OLED patents, respectively, 3713 and 1231, Seiko Epson Co., Ltd., Semiconductor Energy Research Institute and Sanyo respectively The third, fourth and fifth places have 383 patents, 327 and 119 patents respectively. LG and Samsung's patent registration, between 2008 and 2012, the average annual success rate was 87.1% and 83.4%.
The head of the KIPO review department said that with the PDP, LCD patents are dominated by US and Japanese manufacturers, and OLED patents have been seized by Korean companies.

Ethernet power supply system is referred to as POE power supply, which consists of Ethernet power supply equipment and Ethernet power equipment. It can transmit data and provide DC power supply to client equipment only through one Ethernet cable, without the need for additional wiring.Gigabit POE Switches are divided into managed and non-managed POE switches ,non-standard POE switches which do not meet the IEEE802.3af/at. and also it has indoor series and outdoor series  with 10/100/1000M input and output port.


1. Can recognize the impedance of the signal. When an input voltage is applied to the device, it must be roughly identified within the defined voltage range. When an ethernet power device pleads for power supply, it first sends out the voltage signal of 2.5V~10V to Ethernet. After detecting the voltage signal, the power facility puts a 23750 ohmic resistor on the power supply circuit, and the current changes with the input voltage. By detecting the current, it is confirmed that there is an effective Ethernet power supply at the Ethernet cable terminal. If the arranged resistance value is in the area of 26250 / 45000 ohms, it is considered that the ethernet equipment is effective but does not need to supply power. Resistive values of other sizes mean that the detected ethernet equipment is useful. 

2. Type. Electricity is equipped with a type of gap, each type corresponding to not a certain current. Analogy, the "0" class of electricity is equipped with a current of 0.5 Ma 4 Ma. When an effective signal is detected by a power supply, it is classified. The specific method is to lift the voltage to 15.5V or 20.5V on the Internet link, so that the Ethernet power equipment loses a static current, and then completes the classification of the power facilities according to the current scale. 

3. Open coherent connection. There are two kinds of switches connected to Ethernet power supply (Poe power supply), one is bipolar crystal switch, which has high utility and low capital, and the other is MOSFET switch, which has extremely high power performance and can be close to 100th.


Suitable for different Ethernet devices such as: IP phone, network security camera, PDA, mobile phone charger, card reader, etc.
