This article will focus on exploringPI copper plated filmThe difference between ITO film as a conductive layer for touch screens and the research progress of Advanced Institute (Shenzhen) Technology Co., Ltd. in related fields are mentioned.

PI Copper Coating: The Rise of Emerging Stars

PI copper plated film is a composite material formed by coating copper on the surface of polyimide film. Polyimide as a type ofHigh performance polymer materialsKnown for its excellent heat resistance, corrosion resistance, good mechanical strength, and electrical insulation. When copper is combined with polyimide, this composite material not only inherits the above advantages of polyimide, but also has the high conductivity of copper, making it an ideal choice for high-performance electronic components.

1. High heat resistance and conductivity: Polyimide is one of the most thermally stable polymers to date, allowing PI copper plated films to maintain stable performance even in high temperature environments. The copper coating endows the PI copper plated film with excellent conductivity, meeting the current transmission requirements of electronic components.

2. Flexible application: The lightweight and durable characteristics of PI copper plated film make it suitable for smart wearable devices such as flexible displays and sensors, which can be closer to the human body and provide a more comfortable and convenient user experience.

3. Microelectronics Packaging and New Energy: In today's increasingly evident trend of miniaturization and integration, PI copper plated film has become an ideal choice in the field of microelectronics packaging due to its excellent thermal stability and electrical performance. Meanwhile, in new energy devices such as lithium batteries and solar cells, PI copper plating film also plays an important role in improving the energy conversion efficiency and safety of the battery.

ITO film: the position of traditional king

ito filmIt is an n-type semiconductor material with high conductivity, high visible light transmittance, high mechanical hardness, and good chemical stability. It is the most commonly used thin film material for transparent electrodes in liquid crystal displays (LCD), plasma displays (PDP), electroluminescent displays (EL/OLED), touch screens (TouchPanel), and other electronic instruments.

1. Conductivity and transparency: ITO film has good conductivity, with a resistivity as low as 10-4 Ω· cm, and a visible light transmittance of over 85%, ensuring the clarity and sensitivity of the touch screen.

2. Complex processing capability: ITO film layer has excellent acid etching and photolithography properties, making it easy for fine processing and can be etched into different electrical patterns to meet the diverse design needs of touch screens.

However, with the rapid development of the display device industry, the limitations of ITO thin films are gradually becoming apparent. Especially in large-sized, flexible display applications, the inherent issues of conductivity and transmittance of ITO films are difficult to overcome, prompting manufacturers to seek alternative solutions.
