Abstract

The invention discloses an array base plate and a display panel. Through the arrangement of a virtual electrode in a cutting region of the array base plate, and in addition, touch control electrodes are electrically connected with the virtual electrode through a touch control electrode lead wire, so that the touch control electrodes are in short circuit connection, i.e., the voltage difference among the touch control electrodes is zero; or a first electrostatic defending device is arranged in a step region of the array base plate, in addition, the touch control electrodes are electrically connected onto a first short circuit ring through the touch control electrode lead wire and the first electrostatic defending device, when the first electrostatic defending device is switched on through the static electricity of the touch control electrodes, the touch control electrodes conduct the static electricity on the touch control electrodes onto the first short circuit ring through the first electrostatic defending device, and the voltage of the static electricity of the touch control electrodes is reduced. Through the technical scheme provided by the invention, the static electricity discharge among the touch control electrodes can be prevented, so that the damage to the touch control electrodes and the display panel due to the static electricity discharge can be avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to an array substrate and a display panel. Background technique [0002] With the development of modern electronic technology, corresponding components are arranged in the display panel to realize corresponding functions, such as realizing capacitive touch function, etc., so as to bring convenience to users. [0003] At present, according to the formation method of capacitance, capacitive touch can be divided into self-capacitive touch and mutual capacitance touch. Among them, the self-capacitive touch is realized by the capacitance formed between the touch electrode and the ground to realize the touch function, and the mutual capacitance touch Capacitive touch is realized by the capacitance formed between the touch driving electrode and the touch sensing electrode to realize the touch function. [0004] like figure 1 As shown, the display panel 10 is a display panel that...
