Abstract
The present disclosure provides a method and device for controlling a touch screen, and an electronic device. The method includes: applying a first driving voltage to a voltage input terminal of the bridge, and obtaining a first voltage difference between a first voltage output terminal and a second voltage output terminal of the bridge corresponding to the first driving voltage; determining a first equivalent resistance value of the bridge corresponding to the first driving voltage at a current temperature according to the first driving voltage and a preset equation; determining a first compensation voltage value corresponding to the current temperature according to the first equivalent resistance value, the first voltage difference, and a preset formula; determining whether to trigger a touch unit corresponding to the bridge according to the first voltage difference and the first compensation voltage value.
