Thus, the present application is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed herein.
The first embodiment: as shown in fig. 1, for the shunt circuit of the display device provided in the present application, the shunt circuit includes at least one scan voltage output module, the at least one scan voltage output module includes a target scan voltage output module, and the target scan voltage output module includes: the main current submodule 10 is used for receiving an input scanning voltage of the display device and outputting the scanning voltage to the current dividing submodule; and the shunt submodule 20 is electrically connected with the main current submodule and is used for receiving the scanning voltage of the display device output by the main current submodule and shunting and outputting the scanning voltage.
When the display device is controlled to display through the scanning voltage, bright blocks and dark areas of low-gray-scale pictures exist, namely a high-contrast coupling phenomenon, the reason for the phenomenon is the increase of instantaneous current, so that the potential at the scanning voltage is influenced by a brighter area in the display device, the potential is further increased, the two ends of the LEDs in the same row of blue areas are caused to have reduced voltage, and the pictures of the display areas in the same row are darker than those of non-display devices. In addition, just because the number of the LEDs used in the mini-LED technology is far greater than that of a general display device, the area of a dark area in the display device is larger, and to solve this problem, a shunt submodule may be added at a main current position where a scanning voltage is applied and removed to reduce the potential increased due to the instantaneous increase of the current, so as to eliminate the problem that the picture is dark due to the excessively high potential.
That is, according to the shunt circuit of the display device provided by this embodiment, on the basis of the main current voltage terminal, a shunt submodule is added, and through the shunt function, the potential of the input terminal of the main current voltage, which is increased due to the instantaneous increase of the current, is reduced, so that the situation that the picture of the display device is dark is avoided, and the brightness of the picture of the display device is ensured.

Therefore, the shunt resistor can effectively avoid the problem that the MOS on the shunt line is damaged due to the increase of instantaneous voltage.
In addition, after the shunt resistor is connected to the shunt line, the shunt module and the main current module are in a parallel state, so that the overall load impedance cannot change too much, the potential change can be controlled better, and the precision of potential control is improved.
