Description

technical field [0001] The present invention relates to the field of display technology, in particular to a device and method for detecting electrical properties of touch electrodes. Background technique [0002] Recently, capacitive touch screens have been welcomed by the public for their high light transmittance, wear resistance, resistance to environmental temperature changes, environmental humidity changes, long life, and the ability to realize advanced complex functions such as multi-touch. [0003] At present, capacitive touch screens are divided into mutual capacitive touch screens and self-capacitive touch screens. Among them, the mutual capacitance touch screen is provided with two opposite mutual capacitance electrode layers. When the human body does not touch the screen, a fixed size mutual capacitance is generated between the corresponding mutual capacitance electrodes in the two mutual capacitance electrode layers. When the human body When the screen is touched...
