Claim 3:
4. The backlight module according to claim 3, wherein the controller stores a first correspondence relationship between the target gray scale and a first voltage; the controller is configured to: obtain, when the j-th sub-pixel connected to the i-th data line does not emit light, the corresponding first voltage from the first correspondence relationship according to the target gray scale of the (j+1)-th sub-pixel connected to the i-th data line, and input a voltage to the input terminal of the second transistor of the drive circuit corresponding to the (j+1)-th sub-pixel connected to the i-th data line according to the first voltage;
the controller further stores a second correspondence relationship between the target gray scale and a second voltage; the first voltage corresponding to any target gray scale in the first correspondence relationship is greater than the second voltage corresponding to said any target gray scale in the second correspondence relationship; and the controller is configured to: obtain, when the j-th sub-pixel connected to the i-th data line emits light, the corresponding second voltage from the second correspondence relationship according to the target gray scale of the (j+1)-th sub-pixel connected to the i-th data line, and input a voltage to the input terminal of the second transistor of the drive circuit corresponding to the (j+1)-th sub-pixel connected to the i-th data line according to the second voltage.
