Abstract
Description
[Technical Field] A touch panel, particularly a borderless touch panel. [Previous Technology] Please refer to Figures 13 and 14, which are schematic diagrams of a conventional touch panel, including a first substrate 90, a plurality of first axial sensing lines 91, a plurality of second axial sensing lines 92, a first running line area 93, a second running line area 94, and a second substrate 97. In this embodiment, the first axial sensing lines 91 are formed on the upper surface of the first substrate 90, and the second axial sensing lines 92 are formed on the upper surface of the second substrate 97. The first running line area 93 and the second running line area 94 are located on both sides of the first substrate 90 and are adjacent to the first axial sensing lines 91. The first running line area 93 has a plurality of first running lines 931, which are connected to the corresponding first axial sensing lines 91; the second running line area 94 has a plurality of second running lines 941, which are connected to the corresponding first axial sensing lines 91. The second axial sensing lines 92 are respectively connected to a plurality of third running lines 96, which are distributed on the upper surface of the second substrate 97. The first running lines 931, the second running lines 941, and the third running lines 96 are connected to a circuit board 99. An adhesive layer 98 is provided between the first substrate 90 and the second substrate 97. The adhesive layer 98 can be an optical adhesive (OCA) used to connect and fix the first substrate 90 and the second substrate 97, and to insulate the first axial sensing lines 91 and the second axial sensing lines 92. Since the first running lines 931 and the second running lines 941 are respectively distributed in the first running line area 93 and the second running line area 94, the first substrate 90 must reserve the area of the first running line area 93 and the second running line area 94 so that the first running lines 931 and the second running lines 941 can be routed on the first substrate 90, which is not conducive to achieving the requirement of narrow bezel of the panel.
