Abstract: The invention provides a display panel and a method for detecting the same, a display device and a storage medium. The display panel comprises a substrate having a display area; a plurality of pixel units disposed in the display area; a plurality of signal lines electrically connected to the plurality of pixel units to transmit driving signals to the plurality of pixel units; a charge coupling unit corresponding to at least a part of the plurality of signal lines for coupling the driving signals into potential signal; and a voltage detection unit electrically connected to the charge coupling unit for receiving the potential signal and determining the driving signals.

Abstract: An electrical connector includes an insulating housing, a terminal pack module, at least one propping element and a shielding shell. A front of the insulating housing defines a receiving space. At least one fastening groove is opened in an outer periphery of the insulating housing. A bottom of the fastening groove defines a fastening hole. A plurality of terminals is received in the insulating housing. The propping element is received in the corresponding fastening groove and has a base portion. An elastic portion is extended frontward from the base portion, and a contacting portion is protruded inward from a free end of the elastic portion for being inserted into the fastening hole to be exposed to the receiving space. A shielding shell encloses the insulating housing and the propping element. The shielding shell has at least one mouth corresponding to the fastening hole and the contacting portion.
