Abstract: A protection structure includes a substrate, a signal wire pattern, a protective ring and micro-blocks. The substrate has a touch sensing pattern including sensing strings. The signal wire pattern has conductive wires. Each conductive wire electrically connects one of the sensing strings to a signal processor. The protective ring is formed at a peripheral zone of the substrate and around the touch sensing pattern. The micro-blocks are disposed in the protective ring and have electric conductivity. A gap is disposed between every adjacent two of the micro-blocks for insulation.
