Abstract

The embodiment of the invention discloses a method and device for processing information and electronic equipment. The method and device are applied to the electronic equipment with a capacitive touch display unit. When it is detected that the electronic equipment is connected with an external charging device, whether currents of the external charging device have interference signals is monitored, and whether misinformation points exist in the capacitive touch display unit is monitored; when it is detected that interference signals exist in the currents of the external charging device, and the misinformation points exist in the capacitive touch display unit, the charging mode of the charging device is controlled and adjusted, the current first charging mode of the electronic equipment is switched to the second charging mode, charging currents in the second charging mode are smaller than that of the first charging mode, and therefore common mode interference due to the fact that the electronic equipment with the capacitive touch display unit is connected with an external power supply is lowered.

Description

technical field [0001] The present invention relates to the field of information technology, and more specifically, relates to an information processing method, system and electronic equipment. Background technique [0002] With the rapid development of electronic technology, most electronic devices use capacitive touch screens, and capacitive touch screens have an unavoidable problem—common mode interference. Common mode interference can cause false alarm points on the touch screen. For example, after a capacitive touch screen electronic device is connected to an external power source (such as a charger), when touching the touch screen, there will be random jumping and no touch phenomenon, and even the capacitive touch screen electronic device will generate a touch alarm when the finger is not touched Phenomenon. [0003] Therefore, how to reduce the common-mode interference of the capacitive touch screen electronic equipment has become an urgent problem to be solved. C...
