Claim 4:
5. The drive module according to claim 4, wherein a preset voltage multiplying relationship of the analog power voltage AVDD comprises AVDD=a*VCI+b*VDDI;
a preset voltage multiplying relationship of the VCL voltage comprises VCL=−c*VCI;
a preset voltage multiplying relationship of the high-level voltage VGH comprises VGH=d*AVDD+e*VCI; and
a preset voltage multiplying relationship of the low-level voltage VGL comprises VGL=f*VCL— g*VCI— h*AVDD,
wherein VCI denotes the analog reference voltage signal, VDDI denotes a power supply voltage received by the driver chip, a, b, c, d, e, f, g, and h are voltage multiplying coefficients, and a, b, c, d, e, f, g, and h are natural numbers.
