Touch panel and touch electronic device

A touch panel configured to be mounted inside a casing unit, said casing unit including a main casing and a side frame connected to a periphery of said main casing, said side frame being provided with at least one key icon and a side frame power switch, and said touch panel comprising:

• a flexible substrate correspondingly disposed at an inner surface of said casing unit, said flexible substrate including a first area that corresponds to said main casing and a second area that corresponds to said side frame;
• a first electrode pattern formed on a surface of said flexible substrate and located at said first area;
• at least one second electrode pattern formed on said surface of said flexible substrate and located at said second area, said at least one second electrode pattern corresponding to said at least one key icon and being isolated from said first electrode pattern;
• a trace structure formed on said surface of said flexible substrate, said trace structure including a plurality of traces and a plurality of contact pads arranged between said first electrode pattern and said at least one second electrode pattern;
• said first electrode pattern connected with at least one contact pad through at least one trace, said at least one second electrode pattern connected with at least another contact pad through at least another trace and independently controlled to be turned on and off by said side frame power switch;
• a reinforcing structure composed of a plurality of electrode units fabricated from metal mesh, said reinforcing structure being formed at a junction of said first area and said second area of said flexible substrate and being disposed on said first electrode pattern or said trace structure at said junction.
