An embodiment of the present invention provides a working method of a display device, where the display device includes N groups of gate lines and M groups of data lines, where the N groups of gate lines and the M groups of data lines define a plurality of sub-pixels, each group of gate lines includes a plurality of gate lines, each group of data lines includes a plurality of data lines, and N and M are integers greater than 1, as shown in fig. 1, the working method includes:
step 101: according to the display mode of the display device, a grid driving signal is input to at least one group of grid lines in the N groups of grid lines, and a data signal is input to at least one group of data lines in the M groups of data lines.
In this embodiment, according to the display mode of the display device, the gate driving signal may be input to all of the N groups of gate lines of the display device, or may be input to a part of the N groups of gate lines; the grid driving signals are input into all the M groups of data lines of the display device, or the data signals are input into a part of the M groups of data lines, so that when the display device has poor signal lines, the signals can be input through the poor signal lines, other signal lines are used for displaying, the resolution of a display picture is modified, the service life of the display device is prolonged, and the waste of the display device is avoided; in addition, when the display device does not have the signal line defect, the display device can be used for displaying pictures with different resolutions. For example, if a signal line of a certain display device is defective in the mass production process, the display device can be sold in a degraded state by using other signal lines except the defective signal line to display, and the display device does not need to be scrapped, so that waste can be effectively avoided. In the using process of the display device, if the display device has poor signal lines, a user can modify the resolution of the display device by selecting different display modes, so that the service life of the display device is prolonged.
Wherein, the display device can be: the display device comprises any product or component with a display function, such as a liquid crystal television, a liquid crystal display, a digital photo frame, a mobile phone, a tablet personal computer and the like, and further comprises a flexible circuit board, a printed circuit board and a back plate.

In order to ensure the uniformity of the display screen, the number of the gate line groups and the number of the data line groups participating in the display should be uniformly distributed on the display area of the display device, rather than being concentrated on a part of the display area of the display device.

In the using process of the display device, if the display device has bad grid lines or data lines, a user can modify the resolution of the display device by selecting different display modes and display by using other grid lines or data lines except the bad grid lines or data lines, thereby prolonging the service life of the display device.

the display mode of the display device includes a normal display mode and a failure display mode, and the display device further includes:
and the detection chip is used for detecting whether the display device has bad data lines or bad grid lines, and judging that the display device is in a fault display mode when the display device has the bad data lines or the bad grid lines.
7. The display device according to claim 6,
the driving chip is specifically used for inputting a gate driving signal to the N groups of gate lines and inputting a data signal to the M groups of data lines when the display device is in a high-definition display mode;
when the display device is in a low-definition display mode, determining a grid line group participating in display from N groups of grid lines and a data line group participating in display from M groups of data lines according to the resolution ratio corresponding to the low-definition display mode, inputting a grid driving signal to the determined grid line group, and inputting a data signal to the determined data line group.
8. The display device according to claim 6,
the driving chip is specifically configured to input a gate driving signal to other groups of gate lines except the nth group when the detection chip detects that there is a gate line defect in the nth group of gate lines, where N is a positive integer not greater than N; and/or
When the detection chip detects that data line faults exist in the mth group of data lines in the M groups of data lines, data signals are input into other groups of data lines except the mth group, and M is a positive integer not larger than M.
