Piezo-capacitive effect-based printed flexible touchscreen display |
摘要 |
A piezo-capacitive effect-based printed flexible touch screen, comprising a printable layer, a printing ink layer, a transmissive layer, an electrode layer A, an electrically-controlled optical switch layer, an electrode layer B, a transparent flexible layer, and an electrode layer C disposed successively from bottom to top. The printable layer is a flexible insular material that is foldable and printable. The printing ink layer is a CMYK ink dot matrix printed on the printable layer. The transmissive layer is a flexible transmissive material. The transparent flexible layer is a TPE-thermoplastic elastomer. The electrically-controlled optical switch layer is a PDLC film. The electrode layer A, electrode layer B, and electrode layer C are all ITO conductive film layers having electrode array engraved thereon, while the electrode arrays of the electrode layer A and the electrode layer C are in same direction and are perpendicular in direction to the electrode array of electrode layer B. The screen is a touch screen and allows for facilitated colorization, rapid response time, reduced driving voltage, simplified manufacturing method, and reduced manufacturing costs. |
