OLED has all the advantages of solid state, active illumination, high contrast, ultra low power consumption, no viewing angle limitation, fast response, wide working range, easy implementation of flexible display and 3D display, etc. It will become the fastest growing new model in the next 20 years. Display technology. At the same time, OLED is an ideal planar light source due to its large-area film formation, low power consumption and other excellent characteristics. It also has broad application prospects in the future energy-saving and environment-friendly lighting field.
OLED technology development accelerates market maturity
The industry generally believes that TFT-LCD is the mainstream product in the field of flat panel display, and OLED is the most promising product in the new flat panel display. However, various types of display devices have their advantages and disadvantages, and each has its own service area and user group. Therefore, which products in the future market can become mainstream, depending on the product performance and the maturity of the industry chain and the market strategy of the corresponding companies. For the small and medium-sized PM-OLED, with the further development of the upstream industry and the improvement and innovation of the production process, the cost advantage will also be highlighted, and it will be more favored by the market. In the large size field, AM-OLED technology also has a lot of room for development. In short, OLED will grow rapidly with its unique characteristics and advantages, and become one of the most ideal displays in the future society.
After the 1990s, OLED technology has developed rapidly. The luminous efficiency and lifetime of small molecule and high molecular organic materials have been greatly improved, and there are many technological breakthroughs in the structure of display devices. Since the birth of the first OLED product for car audio display in 1997, OLED display has been widely used in consumer electronics and industrial products such as mobile phones, MP3, digital cameras, instrumentation, medical, industrial control and so on. . In 2007, Sony Corporation of Japan introduced an 11-inch OLED color TV set, which is the first to realize the breakthrough of OLED in medium and large size, especially in the field of TV. Its excellent performance highlights the huge application prospect of OLED in the field of large-size display.
In the large size field, AM-OLED technology still has a lot of room for development. At this stage, TFT-LCD is still the leader in this field. After years of development, TFT-LCD has matured, the size is constantly growing, the market share is high, and new technologies are introduced and commercialized. AM-OLED and TFT-LCD are very different. TFT-LCD Requires backlight, OLED does not need backlight, due to different illuminating mechanism, OLED viewing angle shows good performance, low overall power consumption, good low temperature resistance, thin screen, especially in response speed, OLED microsecond The level of response speed makes the picture clearer and smoother without tailing.
OLEDs are currently in the process of breaking through small to large sizes. Nowadays, the world's largest companies with TFT R&D and manufacturing capabilities are optimistic about the future of AM-OLED and invest a lot of money in research and development. The launch of AM-OLED products such as Sony, Samsung SDI, and CMEL further promoted the development of AM-OLED industry and technology. AM-OLEDs still need to improve in terms of production process and yield improvement, but these problems will continue to improve and resolve over time. With the maturity of OLED technology and industry, and the further decline in cost, OLED will be flat with TFT-LCD in the next 5-10 years, and even the market performance is better than TFT-LCD.
