OFweek Semiconductor Lighting Network: On December 24th, Kunshan City Industrial and Research Institute's new flat panel display technology center and Visionox successfully developed the 2.8-inch color organic light-emitting display (AMO LED ) display in China, realizing the red, green and blue primary colors. It shows that the whole line has opened up the low-temperature polysilicon backplane and organic light-emitting display (OLED) manufacturing process technology. This is another major technological advancement of China's OLED industry after Visionox relies on its own technology to realize the industrialization of passive-driven organic light-emitting display (PMOLED) technology. It marks that China has mastered the core technology of large-size active matrix organic light-emitting display (AMOLED) through independent development, and has taken a solid step on the road of AMOLED industrialization.
OLED refers to the phenomenon that organic semiconductor materials and luminescent materials are driven by electric field to cause luminescence by carrier injection and recombination. O LED technology can be divided into PMOLED and AMOLED according to different driving methods. Among them, AMOLED as a new generation of display technology is not only one of the seven strategic emerging industries that China is focusing on, but also a hotspot and a difficult point in the development of the global OLED industry. As an industry with high technology dependence, it needs a group of enterprises with strong technology and strong innovation ability to drive industrial development. The new flat panel display technology center of the City Industrial Technology Research Institute and the core technology that Visionox has taken the lead in China have further narrowed the gap between China's OLED industry and the world's advanced level.
It is understood that China's OLED industry started at the beginning of this century. In 2002, Tsinghua University and Visionox built China's first PMOLED pilot line. In 2003, it completed the pilot process technology development and achieved the first small-scale production and sales of PMO LED products in China. In 2008, Tsinghua University and Visionox built the first large-scale production line of PMOLED in Kunshan, realizing the large-scale production of PMOLED.
While realizing the rapid development of PMOLED, in September 2009, with the strong support of the municipal government, Kunshan Industrial Technology Institute, Visionox and Kunshan Development Zone jointly invested and established Kunshan Flat Panel Display Center. In June 2010, Kunshan Flat Panel Display Center built the first AMOLED pilot production line in China. After half a year of hard work, it successfully developed the key process technology of AMOLED, which laid a good foundation for accelerating the industrialization process of AMOLED in China.

Plastic Package Diode.Among the electronic components, a device having two electrodes allows only the current to flow in a single direction, and many uses apply its rectification function. The Varicap Diode is used as an electronic adjustable capacitor. Most of the diodes have a current directionality that we often call the "Rectifying" function. The most common function of a diode is to allow only current to pass in a single direction (referred to as forward bias) and block in the reverse direction (referred to as reverse bias). Therefore, the diode can be thought of as an electronic version of the check valve.
