Identity recognition display device, and array substrate and identity recognition circuit thereof
An identity recognition device, and an substrate and an identity recognition circuit are disclosed. In the substrate, a plurality of second recognition output lines are added to be arranged in pairs with first recognition output lines. A control signal loaded to the control signal line will be coupled to the first and second recognition output lines by the parasitic capacitance between the control signal line and the recognition output lines to cause similar signal interference to the first and second recognition output lines. During the identity recognition time period, the signal interference in the electric signal outputted by the first recognition output line can be removed by utilizing the similar noise signal received by the second recognition output line, in such a way to improve the signal-to-noise ratio and detection precision of the identity recognition signal.
