Abstract
A touch control substrate, a preparation method thereof, a touch control module, and a display device are provided. The touch control substrate comprises: a substrate, a conductive functional layer, and a second protection medium. The conductive functional layer is arranged on one side of the substrate, and comprises patterned nano conductive structure, first protection medium, and frame lead structure. The conductive functional layer is protected by providing a two-layer protection medium structure, wherein the first protection medium fixes the structural position of the nano conductive layer and protects the partial structure of the conductive functional layer, and the second protection medium at least completely covers the nano conductive layer located in the conductive functional area; and at the same time, the touch control substrate directly disposes the frame lead layer in the peripheral area of the nano conductive layer, making the frame lead directly contacting the nano conductive layer.
