For example, in order to improve the accuracy of the fingerprint detection assembly 2, the fingerprint detection assembly 2 may be closer to the surface of the electronic device equipped with the screen module 100 relative to the display panel 1. Specifically, the fingerprint detection assembly 2 may include a first capacitor plate 21 and a second capacitor plate 22, a preset distance is formed between the first capacitor plate 21 and the second capacitor plate 22, the first capacitor plate 21 may include a plurality of capacitors, the second capacitor plate 22 may also include a plurality of capacitors, the plurality of capacitors included in the first capacitor plate 21 and the plurality of capacitors included in the second capacitor plate 22 may cooperate to form a plurality of sets of capacitors arranged oppositely, and a capacitance change amount between each set of capacitors is linearly related to a distance change amount between the sets of capacitors.

For example, as shown in fig. 1, the first capacitor plate 21 may include a capacitor 211 and a capacitor 212, the second capacitor plate 22 may include a capacitor 221 and a capacitor 222, the capacitor 211 on the first capacitor plate 21 and the capacitor 221 on the second capacitor plate 22 are disposed oppositely to form a set of capacitors, the capacitor 212 on the first capacitor plate 21 and the capacitor 222 on the second capacitor plate 22 are disposed oppositely to form a set of capacitors, a change amount of the capacitance between the capacitor 211 and the capacitor 221 is linearly related to a change amount of the distance therebetween, and a change amount of the capacitance between the capacitor 212 and the capacitor 222 is linearly related to a change amount of the distance therebetween.

Then, when the user presses the first electrode plate 21, the total capacitance:

C＝C₀+△C＝C₁×C₂×S/(d₀-△d)

＝(C₁×C₂×S/d₀)/((d₀-△d)/d₀)＝C₀/(1-△d/d₀)；

wherein the content of the first and second substances,

△C/C₀＝(C₀/(1-△d/d₀)-C₀)/C₀＝1/(1-△d/d₀)-1

＝(1/(1-△d/d₀))×(△d/d₀₎；

therefore, the first and second electrodes are formed on the substrate,
