Abstract
A touch panel includes a transparent base board, a mesh-shaped sensor portion formed on the base board and made of piezoelectric materials, a mesh-shaped black matrix formed on the sensor portion; and a pixel portion formed on portions of the base board exposed from the sensor portion and the black matrix for displaying images. When the base board is touched, the sensor portion transforms the pressure on the base board into piezoelectric signals for inputting operating instruction.
