What Is Air Bonding And Optical Bonding?

Air bonding, also known as frame lamination, is a screen assembly technique that utilizes adhesive tape to join the touchscreen and the LCD (liquid crystal display) around the edges, creating a space between them. This approach involves attaching the touchscreen to the LCD with adhesive tape, resulting in an air gap between the layers.

Optical bonding, referred to as full lamination or direct bonding, is a vital process in display manufacturing. It entails attaching a glass or touch panel directly to the LCD/LED display using an adhesive layer. This method improves the display's visual clarity and contrast by removing the air gap, thereby decreasing light reflection and glare. Additionally, it enhances durability, making screens more resistant to impacts and environmental factors such as dust and moisture. Particularly advantageous for devices used outdoors or in industrial settings, optical bonding also increases touch sensitivity in touch-enabled devices. This process is crucial in a variety of applications, including consumer electronics, automotive, medical, and industrial equipment.
