The optically clear adhesive 102 described above can be understood as a special adhesive for bonding transparent optical components. It can be colorless and transparent, with a light transmittance of over 90% and good cementation strength. The optically transparent adhesive 102 can generally be cured at room temperature or medium temperature, and has a small curing shrinkage. Adhesives such as silicone, acrylic, unsaturated polyester, polyurethane and epoxy can bond optical components. Some treatment agents are usually added during formulation to improve their optical properties or to reduce cure shrinkage. Of course, the optically transparent adhesive 102 may be a natural resin optical glue or a synthetic resin optical glue or the like. The polarizer 103 can filter out some light to make the display have a better display effect. The above display panel 104 may be glass including an organic light emitting diode, or may be glass including liquid crystal. The protective foam 105 can protect the display panel 104, so that other materials are not easily contacted to the display panel 104, and since the protective foam 105 has a certain degree of softness, when the mobile terminal suddenly receives some force, the display can be displayed.
