Molybdenum target of the sixth generation AMOLED panel
The reason why liquid crystal displays such as mobile phones and televisions can display images depends on a thin layer of metal film on the glass substrate that can not be seen by the naked eye. This layer of metal film with signal transmission function is equivalent to the "precision circuit board" of liquid crystal display, which transmits the color and brightness information of the display screen to each pixel, so as to accurately image. Among them, molybdenum target is one of the key materials for sputtering this metal film.
With the continuous development of liquid crystal display technology, AMOLED display technology has increasingly become a research hotspot in the field of display in the world due to its light weight, power saving and bright colors. Among them, the sixth generation AMOLED panel wide integrated molybdenum target has a length of 2.3 meters, a width of 1.8 meters, and a single weight of more than 600 kg. Its production technology has been mastered by a few foreign countries before, and domestic products are still blank.
In order to break the long-term monopoly pattern of molybdenum target products by foreign suppliers, in recent years, the Under the support of the project "Research on key forming technology of high quality molybdenum powder preparation and large-scale sputtering coating molybdenum target", the project focused on the control technology of large-scale molybdenum sheet pressing forming, which made the purity of molybdenum target metal above 99.95%, the grain size less than 100μm, and the surface near zero defect. All performance indexes reached the international advanced level, and the sixth generation AMOLED panel was wide The integrated molybdenum target has been put into the market.
At present, we are focusing on the research and development of TFT-LCD and AMOLED high-purity molybdenum target products and molybdenum alloy target products for high-generation panel production line with higher overall performance.
