Nano-silver conductive film and large-size nano-silver capacitive screen

Abstract

The invention relates to the field of nano-silver conductive films, in particular to a nano-silver conductive film capable of reducing the failure rate of a nano-silver film channel and a large-size nano-silver capacitive screen. According to the nano-silver conductive film, a TX-direction laser pattern and an RX-direction laser pattern are etched on the conductive film, the conductive film is divided into a middle part and an edge part in the TX direction, and the line spacing of the TX-direction laser pattern of the middle part is larger than that of the TX-direction laser pattern of the edge part. By slightly expanding the line distance of the middle part of the laser pattern in the TX direction, the damage of current impact to the nano-silver form can be weakened under the conditions of maintaining the current intensity and not influencing the touch effect, the connection strength and form of the nano-silver line can be maintained more effectively, and the failure rate of the nano-silver line layer in the middle of the TX-direction conductive film is reduced; therefore, the resistance is controlled within a stable range, and the service life of the capacitive screen is prolonged.
