Application of high purity molybdenum sputtering target in liquid crystal flat panel displays

With the development of science and technology, molybdenum (Mo) has begun to emerge in many emerging fields, changing human life in all aspects. The most relevant to people’s lives is its application in the manufacture of flat-panel displays. Large-size high-purity molybdenum sputtering targets are the key core raw materials in the manufacture of liquid crystal flat-panel displays, and Mo is one of the preferred materials for sputtering targets for flat-panel displays. Such targets are needed for the screens of electronic products such as daily color TVs, smart phones, tablet computers, and some large household appliances, as well as the control display screens of some military communication equipment.

How is the display of a flat-panel display achieved? Through two pieces of glass separated by vacuum, the glass on the back is used as the cathode. More than 500 million emitter tips are distributed on this piece of glass in the form of a field emitter array. The interval between the emitters is very small, much smaller than the pixels on the TV screen. The emitter tips can be controlled individually or in groups during display. It is made of Mo. This display using Mo has the advantages of wide viewing angle, fast response speed, and very low power consumption. It conforms to the current trend of displays and will undoubtedly become an important boost to the development of flat-panel display technology.

As a new type of component for flat panel devices LCD (liquid crystal display), Mo can greatly improve the performance of LCD in terms of brightness, contrast, color and life. Displays using Mo have unique advantages in environmental protection, compact size and energy saving. At present, in the production process of LCD displays in many developed countries, the use of traditional materials such as nickel and chromium is decreasing and gradually replaced by Mo. Although the amount of Mo is small, it plays an important role in the development of large-screen and high-definition televisions.
