Abstract: A key update method, a network device, a system, and a storage medium, applied to a Bluetooth mesh network. The Bluetooth mesh network includes at least two mesh nodes. A configuration node is a mesh node in the Bluetooth mesh network, and the configuration node is configured to configure a network key of the Bluetooth mesh network. The configuration node determines a first mesh node from mesh nodes in the Bluetooth mesh network, where a network key locally maintained by the first mesh node is inconsistent with a current network key of the Bluetooth mesh network. Therefore, the configuration node encrypts the first network key by using a device key of the first mesh node, to obtain a first ciphertext, and sends a first message that carries the first ciphertext, so that the first mesh node obtains the first network key.

Abstract: A touch panel having at least one non-right angle corner region on a corner of the touch panel is provided. The touch panel includes a first electrode and a second electrode. The first electrode crosses the second electrode, and the first electrode is electrically isolated from the second electrode. The first electrode includes a plurality of first stripe electrodes extending along a first direction. The second electrode includes a plurality of second stripe electrodes and at least one auxiliary electrode. The second stripe electrodes extend along a second direction. The auxiliary electrode is disposed on the non-right angle corner region. An included angle between the auxiliary electrode and the second direction is less than 90 degrees. The auxiliary electrode is electrically connected to at least one of the second stripe electrodes adjacent to the auxiliary electrode.
