Compared with the LCD panel, OLED technology has the advantages of active light, ultra-thin, low-power, colorful, becoming the new hot spot for international field development, global panel makers are major technical layout and industrial layout to the OLED led lights industry transfer.
Existing LCD panel can not self-luminous, it is necessary to rely on a backlight module with certain restrictions, and therefore room for improvement in the energy consumption. Contrast emerging display technologies AMOLED Because of its self-light emitting characteristics, the screen can be controlled according to the pattern of light and dark to each pixel of the panel, it is possible to effectively reduce power consumption.
Driven by South Korea's Samsung, AMOLED is the first application in the mobile phone products, the AMOLED mobile terminal market in less than five inches matured. It can be predicted that the AMOLED panel demand continued to grow. 2015 AMOLED panel shipments are expected to reach 300 million, compared with 2010, an increase of nearly 6 times.
In early 2012, Samsung and LG Display launched the first 55-inch OLED products, set off a large-size OLED TVs investment boom. OLED panel TV market to more than 32 inches further, then TV energy saving effect will be increased dramatically. However, the large size of AMOLED products still faces huge challenges, including the stability of the process, the level of yield, material acquisition, expensive and life issues, which are decided the success of large-size AMOLED LED Display enter the TV market.
Needless to say, AMOLED has inherent advantages in energy saving technology. Face the situation of the Korean factory almost exclusively OLED market, Chinese manufacturers should, on the one hand, the expansion of production capacity of the substrate, and reduce costs; On the other hand, the self-control of the materials and equipment for the development of the OLED industry is also very important.
Furthermore, organic light-emitting layer material is the key to affect the performance of the AMOLED panel, AMOLED energy To Raw materials fuss. At the same current, and how to make the light emitted by the organic light emitting material is more bright, efforts in the direction of material manufacturers. Currently, Japan, Korea, Germany, the U.S. material manufacturers basic monopoly AMOLED luminescent materials market, resulting in high prices of organic light-emitting layer material. In recent years, the South Korean government and the panel manufacturers to support their domestic chemical plants developed organic light-emitting layer material and SMD and LGD try to reduce panel production costs by using cheaper domestic materials. The other hand, the panel makers in china led, although the Taiwanese manufacturers R & D, but also poor luminous efficiency, mainland China is still in the laboratory research and development stage, the material is dependent on foreign imports, the self-control of materials and equipment is also very important for the development of the AMOLED industry.
