LG Launches Largest Size OLED TV in China: Official Listing in the Second Half of the Year
Reverse Conducting Thyristor(RCT) is also called Reverse- appreciation Thyristor.The characteristic is that a diode is connected in reverse parallel between the anode and cathode of thyristor, so that the transmitting junction of anode and cathode is short-circuited.As a result of this special circuit structure, it has high voltage resistance, high temperature resistance, short turn-off time, low switching voltage and other good performance.For example, the turn-off time of the reverse thyristor is only a few microseconds, and the working frequency is dozens of KHZ, which is better than the fast thyristor (FSCR).This device is suitable for switching power supply and UPS uninterrupted power supply. One RCT can replace one thyristor and one continuous current diode respectively.

In January of this year's new Las Vegas show, LG and Samsung and other companies have demonstrated OLED products. At present, Sony has also been developing OLED TVs, and AU Optronics of Taiwan also began mass production of OLED displays for mobile devices in 2011.
Li Dongsheng, chairman of TCL Group, had previously accepted an interview with this reporter that the current technology of OLED in TV screen application is still immature and the cost is very high. However, people in the industry believe that the LCD TV industry cycle is likely to be shortened due to the promotion of OLED by Korean companies, and domestic brands are once again facing the risk of marginalization.
