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.

Abstract: There are provided a pixel charging method, a circuit, a display device and a computer storage medium. The method includes: acquiring a gray-scale value of each row of sub-pixels in an image frame of an image to be displayed; determining a charging time of each row of the sub-pixels according to the gray-scale value thereof; each row of the sub-pixels according to the charging time thereof when a display panel displays the image frame. The charging time of each row of sub-pixels is determined according to the gray-scale value of each row of the sub-pixels, so as to reduce a charging rate difference between two rows of sub-pixels which have a relatively larger gray-scale value difference therebetween, and achieve an effect of improving the uniformity of the charging rates of all rows of sub-pixels in the display panel.
