Problems solved by technology

[0004] In the process of realizing the technical solution of the resistive touch screen in the prior art, the inventors found that the resistive touch screen in the prior art has at least the following problems: it needs to use a touch element with a small area (such as a touch pen or figure 1 Fingertip shown) apply pressure on the resistive touch screen, if the contact area with the resistive touch screen is larger when applying pressure on the resistive touch screen, such as: operate on the resistive touch screen through the belly of the finger, the applied pressure will be dispersed in a larger area On the surface, there will be multiple contact points between the two transparent conductive layers, so that the pressure on each contact point is low, resulting in poor touch sensitivity
