Laminated structure of laminating adhesive

The invention provides a laminated structure of an adhesive, which is suitable for a biometric module under a screen. The laminated structure of the laminating adhesive comprises a first base material, a touch metal layer and a second base material, the first base material is provided with a through hole array. The touch control metal layer is connected with the first base material through a first adhesion layer. And the second base material is jointed with the touch metal layer through a second adhesion layer. The through hole array is arranged on the touch control metal layer in a penetrating mode, a gas flow channel is formed between the touch control metal layer and the first base material, a gas flow channel is formed between the touch control metal layer and the second base material, and bubbles generated after the biometric module under the screen is assembled are reduced. 本发明提供一种贴合胶的叠层结构，适用于屏幕下生物辨识模块。所述贴合胶的叠层结构包含一第一基材、一触控金属层、一第二基材。所述第一基材具有一通孔阵列。所述触控金属层通过一第一黏着层与所述第一基材接合。所述第二基材通过一第二黏着层与所述触控金属层接合。所述通孔阵列是
