Developments in fast cleaning of thin films without wrapping
By Sheila Hamilton, Teknek, Inchinnan, United Kingdom1
Abstract. In the display industry cleanliness of the materials used to build up the display is vital to avoid defects and most major manufacturers use rubber roller contact cleaning systems to remove any particles of contamination. As the films used in displays and backlights get thinner, this type of cleaning equipment can result in process issues relating to the wrapping of the sheets of film around the contact roller due to a variety of adhesion forces.
This paper reports the development work done on a new cleaning roller system to alter several of the factors affecting the adhesion forces between the roller and the film.
