Use Liquid Optical Clear Adhesive to Direct Bond With Glass To Glass Process . Because the liquid state by optical collagen specific UV wavelength light produced according to polymerization, the flow of liquid from the original gel-like polymer into a jelly-like solid; panels fit the surface of the LOCA will fit surface stress, resulting in deformation and panel by panel around the Cell Gap in support of the PS within the deformation, resulted in uneven color around the panel (Mura), how this phenomenon is caused? whether the additives on the LOCA? so to understand this phenomenon and improve the touch panel glass and LCM products Mura Defect, to change the LOCA additives in order to reduce the physical properties panel to Oligomer ratio and panel explore the relationship between the Stress force
