Abstract: Disclosed are a display substrate and a manufacturing method therefor, and a display device. The display substrate comprises: a substrate base, and an active layer, a gate insulating layer, a first metal film layer, an interlayer insulating layer, a second metal film layer, and a passivation layer stacked in sequence on the substrate base. The first metal film layer comprises a pattern of a gate and a gate line. The second metal film layer comprises a pattern of a source/drain and a data line. The gate line and the data line are partially arranged opposite to each other. An oxide metal layer is provided on the surface of the side of the region of the gate line opposite to the data line facing the data line.

Abstract: A method and a device for performing synchronization detection on wireless earphones, wireless earphones and a computer readable storage medium are provided. In the method, a synchronization state between a left earphone and a right earphone of the wireless earphones is acquired when the wireless earphones trigger a target action, where the target action includes any one of: entering a box, leaving a box, entering an ear, leaving an ear and connecting to a terminal; a countdown with a predetermined time duration is started in a case that the synchronization state is a non-synchronous state; and the synchronization state between the left earphone and the right earphone of the wireless earphones is acquired when the countdown ends.
