Embodiments of this present disclosure may include a handle disposed on an outer surface of a housing of electrical circuitry. The handle may provide access to at least a portion of the electrical circuitry. The handle may include a status indicator that emits light in response to a control signal from control circuitry. The status indicator may be disposed around the handle. The control circuitry may detect a state of the electrical protection circuitry. The control circuitry may also transmit the control signal to the status indicator based on the state. The control signal may control one or more properties of the light emitted by the status indicator, and thus indicate to an operator the state of the electrical circuitry.

A display panel includes: a pixel region comprising a plurality of pixels; an open/short test region comprising a plurality of open/short test pads; a dummy stage configured to generate a carry signal in response to a scan start signal; and a plurality of stages configured to sequentially provide a plurality of scan signals to the plurality of pixels in response to the carry signal, wherein the plurality of stages is spaced apart by a first distance from the pixel region, and the dummy stage is spaced apart by a second distance greater than the first distance from the open/short test region.

The present disclosure provides an ink cartridge verification method, a system, a readable storage medium and a device. The method comprises: obtaining the total quantity of spray points of the ink cartridge; detecting the spray points of the ink cartridge to obtain the quantity of malfunctional spray points; when the ratio of the quantity of malfunctional spray points to the total quantity is less than or equal to a first preset ratio, determining that the ink cartridge passes verification. The malfunctional spray points are detected to obtain the ratio of the quantity of malfunctional spray points to the total quantity; when the ratio is low, it is determined that the ink cartridge passes verification, there will be no obvious influences on ink cartridge printing and the ink cartridge can be in normal use; and thus, the printing effect can be reflected after the ink cartridge is regenerated after being filled with ink.

The present invention addresses the problem of diagnosing a failure of a discharge resistor, while suppressing deterioration of discharge capacity. Disclosed is a failure diagnostic device for a discharge circuit 60 for discharging electricity from an electricity storage element 31. The discharge circuit 60 includes a resistance circuit 61 comprising a plurality of resistor blocks B connected in parallel, and each of the resistor blocks B comprises a plurality of discharge resistors Ra, Rb connected in series. During the time when electricity is being discharged from the electricity storage element 31, the failure diagnostic device diagnosis a failure of the resistance circuit 61 on the basis of a voltage or a current at a connection point P between the discharge resistors Ra, Rb.
