It is primarily used as an adhesive between different components in the display and touch screen field. For example, OCA optical adhesive can be used in display and touch screen modules in products such as mobile phones, tablets, smart watches, in-car consoles, touch-screen laptops, and capacitive touch conference tablets. OCA optical adhesive can also be used to assemble lenses in optical lenses and bond and assemble other optical components.

[0003] Currently, when connecting the screen to the device, an OCA optical adhesive bonding mechanism is required for auxiliary operation.
