OCR is the liquid-type-adhesives for reinforcing the device structures mainly cured by UV irradiation, enhancing the brightness, contrast ratio and reliability in attached display
With optical bonding, the light-transmission is increased, resulting in a clearer brightness and display
This makes the light-reflection decreased resulting in higher visibility under bright ambient environments.
And this protects the assembled display structures from the outer environmental(temperature and humidity) and physical(physical load and impact) influences.
