Embodiment Construction
[0032] figure 1 A schematic structural diagram of an existing touch panel 1 is shown. The touch panel 1 includes a protective cover 10 , a first ink layer 12 , an optical adhesive layer 14 and a touch sensing layer 16 . The optical adhesive layer 14 is disposed between the protective cover 10 and the touch sensing layer 16 , and the first ink layer 12 is disposed around the protective cover 10 for shielding the non-sensing area. After bonding the protective cover 10 and the touch sensing layer 16 with the optical adhesive layer 14 , it is necessary to use a curing light source (such as ultraviolet light) to dry and cure the optical adhesive. When the first ink layer is a black or dark ink layer with a high absorption rate, the first ink layer 12 will absorb the heat of the curing light source and deform, resulting in the protective cover 16 and touch The sensing layer 16 is also deformed accordingly.
