Optical Bonding - OCA Bonding, OCR Bonding

Optical bonding can be divided into OCA bonding and OCR bonding (or LOCA bonding). As the traditional air bonding mode, just use double-sided adhesive to stick the LCD display and touch screen bezel to make it bonded together, there must be a gap between the two panels, optical bonding is to use an optical adhesive, resin, or glue to fill the gap, so that it becomes a whole.

Optical bonding has several benefits. It increases the durability of the LCD display panel, making it more resistant to scratches, cracks, and other types of damage that can occur during normal use. Optical bonding also improves the optical performance of the LCD display panel by reducing the amount of reflections and glare on the screen, resulting in better visibility and readability, especially in bright light conditions. It can also improve the touch performance of the touch screen by reducing the distance between the touch sensor and the display panel, resulting in a more accurate and responsive touch experience. Overall, optical bonding is a valuable process that enhances the durability and visual performance of LCD display panels, making them more suitable for a wide range of applications such as marine applications, aviation, military, medical, agriculture, transportation, etc.
