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.
