Abstract
Embodiments of this application provide a display screen and an electronic device. The display screen includes: a display unit, a gate driver on array circuit connected to the display unit, and a detection unit connected to the gate driver on array circuit. The gate driver on array circuit is configured to: generate a scan signal, and drive, by using the scan signal, the display unit to perform displaying. The detection unit is configured to: detect the scan signal of the gate driver on array circuit, and obtain and output a feedback signal, where the feedback signal is configured to determine whether a plurality of gate lines of the display unit are driven simultaneously.
