LCD industry quality inspection solutions:
OLED display technology has the advantages of self-illumination, wide viewing angle, almost infinitely high contrast ratio, low power consumption, high response speed, etc., has become the main trend of development in recent years. In order to cope with the future market demand for AMOLED panels, active layouts at home abroad High-generation production line, but compared with the high-yield rate of TFT as high as 90% more, the low-yield rate has always been a big problem in front of OLED. At this stage, how to optimize quality management do quality control become the core competitiveness of products key.
OLED market demand is strong
As Apple’s adoption of AMOLED panels in the iPhone series is a foregone conclusion, it has driven global panel makers mobile phone brands to start competing to invest in small medium-sized AMOLED panels. Samsung Display has been actively taking out AMOLED panels since 2015, attracting many mobile phone brands such as Oppo, VIVO, Gionee, Meizu other mainland mobile phone brands, which has further driven the trend of AMOLED panels.
The industry predicts that mainland China's shipment of smartphones equipped with AMOLED display panels in 2016 is expected to exceed 88 million units, accounting for 19%. In addition to applications in smart phones, the adoption rate of AMOLED panels in wearable devices, VR, AR has also gradually increased in recent years. It is expected that under the active expansion of production capacity of various panel factories, the capacity area of small medium-sized AMOLED panels in 2019 will reach 14.4 million square meters, the compound annual growth rate will be as high as 30% 2015 to 2019.
High-generation LTPS AMOLED gets attention
LTPS (Low Temperature Polysilicon Technology) was originally a backplane driving technology developed to reduce the power consumption of display screens make the display thinner lighter. After adopting it, the electronic mobility of the liquid crystal display will be higher than that of the traditional a-Si TFT, it has also been introduced into the field of AMOLED display, has greatly accelerated the development mass production of small-sized OLEDs. At present, the mobile display market represented by smart phones is growing rapidly, requiring higher precision larger size, the future demand for flexible screens is also great. The LTPS AMOLED technology with the above characteristics is widely optimistic.
Driven by the market, Korean manufacturers began to adopt 6th generation wire cutting LTPS AMOLED. At the same time, domestic manufacturers also use the 5.5th generation line to make AMOLED, actively promote the construction of the 6th generation LTPS AMOLED production line. The high-generation LTPS OLED production line has gradually attracted the attention of panel manufacturers.
