The invention discloses a fingerprint identification induction circuit board based on TFT-LCD technology and a device thereof, belonging to the technical field of fingerprint identification. The induction circuit board comprises a first insulation layer, a first induction layer, a second insulation layer, a second induction layer and a substrate layer. The induction device comprises a coating, aninduction circuit board, an integrated circuit, a glass substrate, a flexible circuit board and a hard board layer. The TFT-LCD technology is used to produce fingerprint identification, so that the circuit board is remarkable in terms of performance and cost. The TFT-LCD technology for fingerprint identification is to replace the traditional technology design by fabricating the fingerprint identification induction circuit board on the glass substrate through the TFT technology. Compared with the traditional technology, TFT-based fingerprint identification products have the same function as thetraditional fingerprint identification products, and the production cost is lower, the yield is higher, the product is lighter and thinner, and the power consumption is lower.
Description
【Technical field】 [0001] The invention relates to the technical field of fingerprint identification, in particular to a fingerprint identification induction circuit board and a device thereof based on TFT-LCD technology. 【Background technique】 [0002] With the development of science and technology, fingerprint identification technology is also constantly developing and improving. The application of fingerprint identification technology is the most extensive in biometric identification technology, and it embodies the general direction of future fingerprint identification application with huge market potential. The market demand for fingerprint identification products is increasing, and at the same time, the cost of fingerprint identification products is required to be cheaper and cheaper. However, the materials and production methods used in traditional fingerprint identification technology are relatively high in cost, which can no longer meet the requirements of low cost. W...
