Abstract: A display substrate, a display module and a control method are provided in the present disclosure. The display substrate includes a first substrate and a second substrate. The first substrate includes a base substrate, conductive pads, a first switch unit group electrically connected to the conductive pads and signal wires, and a second switch unit group electrically connected to the conductive pads. The display substrate includes a substrate detection phase where all second switch units are cutoff, all first switch units are conducting, and an external detection device input a first detection signal to the substrate through the conductive pads and all first switch units. When the first switch unit group is conducting, the conductive pads are used for substrate detection, and when the second switch unit group is cutoff, the conductive pads in a same pad region are connected each other to be multiplexed as electrostatic conductive pads.

Abstract: A display panel, manufacturing method and display device are provided. The display panel includes: multiple pixel units arranged in an array, each including first sub-pixel and white sub-pixel; and color-film substrate. The color-substrate includes basis substrate and color resist layer formed on the basis substrate, wherein the color resist layer at least includes first color resist in first color resist region and compensating color resist in second color resist region, first and second color resist regions respectively corresponding to first and second sub-pixels. The color-film substrate further includes photo spacer located on one side of color resist layer away from basis substrate, orthographic projection of photo spacer on a plane where display panel is located overlaps orthographic projection of first color resist on this plane, and orthographic projection of photo spacer on this plane overlaps orthographic projection of compensating color resist on this plane.
