Problems solved by technology

[0004] However, when there is no touch point on the capacitive touch screen, the horizontal electrodes of the capacitive touch screen are also sending out driving signals all the time, and all the electrodes in the vertical direction are also always detecting the driving signals, resulting in increased power consumption and affecting the use time of the capacitive touch screen.

Abstract

The invention relates to a touch screen scanning method, a computer device and a storage medium. The method includes the steps: A scanning a touch screen according to a preset scanning frequency to detect whether touch points are arranged on the touch screen or not; B reducing the scanning frequency if the touch points are not detected; C scanning the touch screen according to the reduced scanningfrequency; D repeating the step B and the step C until the scanning frequency is reduced to smallest scanning frequency of normal working of the touch screen, and scanning the touch screen by the smallest scanning frequency. By the method, the power consumption of the touch screen can be reduced, and the use time of the touch screen is prolonged.

Description

technical field [0001] The present application relates to the field of technical touch screen scanning, in particular to a touch screen scanning method, computer equipment and storage media. Background technique [0002] The capacitive touch screen CTP (Capacity Touch Panel) works by using the current induction of the human body. The capacitive touch screen is a four-layer composite glass screen. The inner surface of the glass screen and the interlayer are each coated with a layer of ITO (nano indium tin oxide). As the working surface, four electrodes are drawn from the four corners, and the inner layer of ITO is the screen layer to ensure the working environment. [0003] When a finger touches the capacitive touch screen, it affects the coupling between the two electrodes near the touch point, thereby changing the capacitance between the two electrodes. When detecting the capacitance, the horizontal electrodes send driving signals in sequence, and all the vertical electro...
