  • Patent number: 10066130
    Abstract: A pressure-sensitive adhesive composition, a protective film, an optical element and a display device are provided. The pressure-sensitive adhesive composition has excellent storage stability, exhibits proper low-speed and high-speed peel strengths after formation of a cross-linked structure, and also has an excellent balance between the low-speed and high-speed peel strengths. Therefore, when the pressure-sensitive adhesive composition is applied to a protective film, the pressure-sensitive adhesive composition can have an excellent protective effect, and can also be advantageous to perform a high-speed process since the pressure-sensitive adhesive composition is easily peeled during a high-speed peeling process. In the high-speed peeling process, the pressure-sensitive adhesive composition can exhibit excellent antistatic characteristics.

  • Patent number: 10054720
    Abstract: A Fresnel lens can be adhered to a window in an optical apparatus by liquid optically clear adhesive (LOCA). However, during adhesion the LOCA may spill over into grooves of the Fresnel lens, and the grooves can carry the LOCA into an active area of the lens potentially causing visual artifacts and altering the functional and cosmetic optical qualities of the lens. In examples of the disclosure, one or more grooves along the circumference of a surface of the lens surrounding inner grooves of the Fresnel lens can form a barrier ring that prevents the LOCA from reaching the inner grooves.
