Description

Technical Field

[0001] The utility model relates to the technical field of thin film coating, in particular to a thin film coating device for producing a double-sided ITO touch display screen. Background Art

[0002] In touchscreen technology, indium tin oxide (ITO) is widely used as the conductive layer material for touch sensors due to its high transparency and conductivity. Double-sided ITO touchscreen displays are an advanced touchscreen technology that coats both sides of a thin film substrate (such as PET or glass) with an ITO layer to create a more complex, high-performance multi-touch sensing network. To achieve this goal, efficient double-sided ITO coating equipment is crucial. Before transparent substrate films such as PET or glass enter the coating machine for coating, they require pre-treatment such as cleaning and static elimination.

[0003] With existing technologies, transparent substrate films of different sizes require different winding rollers, and to ensure winding stability, the winding rollers need to be restricted. Therefore, it is necessary to propose a thin film coating device for the production of double-sided ITO touch screen displays. Utility Model Content
