Coating with Gradient color PVD coating machine is the basic link of modern flat panel display industry
Coating is a basic link in the modern flat panel display industry. In order to ensure the uniformity of large-area coatings, increase productivity and reduce costs, almost all types of flat panel display devices use a large number of coating materials to form various functional films. Vacuum coatings are mainly sputtering targets, and many properties of flat panel displays, such as resolution and light transmittance, are closely related to the performance of sputtered films. The main varieties of sputtering targets for flat panel display coatings are: chromium targets, aluminum targets, molybdenum targets, copper targets, aluminum alloy targets, copper alloy targets, titanium targets, silicon targets, niobium targets and indium tin oxide (ITO) targets, etc. .
Vacuum coating technology is a novel material synthesis and processing technology, and it is an important part of the field of surface engineering technology. With the rapid development of the global manufacturing industry, the application of vacuum coating technology has become more and more extensive. From the perspective of the development of semiconductor integrated circuits, LEDs, displays, touch screens, solar photovoltaics, chemicals, pharmaceuticals and other industries, the demand for vacuum coating equipment, technology, and materials is increasing, including electrical films for manufacturing large-scale integrated circuits; digital Data recording storage film that can be magnetized in both longitudinal and transverse directions; optical films that fully display and apply various optical properties; photosensitive films for computer displays; conductive films and antireflection films on TFT and PDP flat-panel displays; in the construction and automotive industries Applied glass coatings and decorative films; protective films and barrier films used in the packaging field; functional films with various functional decorative effects on decorative materials; wear-resistant super hard films applied on the surface of tools and molds; various aspects of nanomaterial research Functional film, etc.
At the same time, with the continuous development of industrial technology, the requirements for the comprehensive performance of materials have also been continuously improved, and the performance of a single material can no longer meet the performance requirements of working machinery in certain specific environments. After decades of development, domestic vacuum ion coating machines have made some progress in automation and technology compared with foreign high-end coating equipment. However, the stability and accuracy of coating products still need to be improved, and high-end equipment is still Rely on imports. At the same time, there is an oversupply situation in the low-end product market for multi-arc ion coating machines, and price competition is fierce.
