21.5inch Optical Bonding LCD Touch Module With USB Controller
21.5inch Optical Bonding Touch LCD Module With USB Controller With AD Board
What's the optical bonding technology?
Optical bonding technology is using OCR or OCA to bond LCD and touch panel without air gap.
Optical bonding is one of key development directions in Touch-China. Optical bonding products with 7”~ 86”are being mass production now. It's the mainstream development trend of the high-end intelligent interaction machine and smart home and other large consumer electronics products in the future.
