  • Publication number: 20180365473
    Abstract: Disclosed are a texture recognition display device and a driving method. The texture recognition display device includes a plurality of first control signal lines and second control signal lines disposed in pairs. During a texture recognition period, the second control signal lines are loaded with a second control signal, the frequency of which is the same as that of a first control signal of the first control signal lines and the phase of which differs from that of the first control signal by 180 degrees. Thus, the noise interference of the first control signal of the first control signal line with a recognition output line may be counteracted, the signal-to-noise ratio of an obtained texture recognition signal can be improved, thereby improving the extraction precision of the texture recognition signal and detection precision.

  • Publication number: 20180357464
    Abstract: 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.
