A method for manufacturing a flexible touch panel, comprising:
- forming a first indium tin oxide (ITO) film layer on a flexible base layer attached to a transparent substrate via an optical adhesive layer;
- and
- patterning the first ITO film layer to form a touch electrode of the flexible touch panel,
- wherein the patterning the first ITO film layer comprises:
- performing a glue coating process, an exposure process, a development process and an etching process on the first ITO film layer, wherein a periphery of the first ITO film layer is shielded by a shutter of an exposure machine during the exposure process, so that an ITO film of the first ITO film layer covering a periphery of the flexible base layer is retained after the etching process.
A method for manufacturing a flexible touch panel, comprising:
- forming a first indium tin oxide (ITO) film layer on a flexible base layer attached to a transparent substrate via an optical adhesive layer;
- and
- patterning the first ITO film layer to form a touch electrode of the flexible touch panel,
- wherein before the forming a first indium tin oxide film layer on a flexible base layer, the method further comprises:
- sequentially attaching the optical adhesive layer and the flexible base layer to the transparent substrate, wherein a border of the optical adhesive layer extends beyond an edge of the flexible base layer,
- wherein the border of the optical adhesive layer extends beyond the edge of the flexible base layer by 1 millimeter to 2 millimeters, inclusively.
A flexible touch panel, comprising:
- a transparent substrate;
- an optical adhesive layer and a flexible base layer sequentially arranged on a side of the transparent substrate;
- and
- a touch electrode arranged on a side of the flexible base layer away from the transparent substrate;
- wherein the touch electrode is an indium tin oxide (ITO) film layer, and the flexible base layer is attached to the transparent substrate via the optical adhesive layer,
- wherein a border of the optical adhesive layer extends beyond an edge of the flexible base layer by 1 millimeter to 2 millimeters, inclusively.
