[0036] In at least one embodiment of the present disclosure, the fact that the two low voltage input terminals are different may refer to the low voltage signals provided by the two low voltage input terminals, respectively, being different.

[0037] In the Fig. In the embodiment of the driver circuit shown in Figure 1, the low-voltage signal provided by the first low-voltage input terminal VL1 may be different from the low-voltage signal provided by the second low-voltage input terminal VL2.
