This disclosure provides a screen state switching method, apparatus, and storage medium. The method includes: determining whether a voltage level generated by a target sensor has changed; and if the voltage level has changed, switching the screen state. This disclosure employs a level-triggered method, switching the screen state only after a change in the voltage level of the target sensor. This avoids misjudgments caused by electromagnetic interference from the surrounding environment when the target sensor uses an edge-triggered method, thus improving the accuracy and usability of screen state switching.
