To prevent from the condition, we use optical and light-cross adhesive glue is stuck between the flat panel and LCD to enhance the contrast ratio. Besides, the adhesive can offer adequate strength to keep it from any damage as scratch, glass smash which is caused by high difference in temperature..., etc. There are many types of gluing way depending on the firm to use.
 
Because of the features of optical bonding technology, it can widely use in pubic for digital signage or interactive equipment as kiosk, query machine, ticket machine or booking machine in outdoor.
