Claim 15:
16. The voltage generation method according to claim 15, wherein the plurality of base voltages further comprise a third base voltage, and importance of the third base voltage is smaller than the importance of the first base voltage and the importance of the second base voltage; and
determining, by the main control unit, the optimal voltage multiplying relationship of the each base voltage in the current drive display mode according to the analog reference voltage signal, the target value of the each base voltage, and the determined actual output value of the preset base voltage in sequence in accordance with the importance sequence of the plurality of base voltages, and calculating the actual output value of the preset base voltage according to the analog reference voltage signal, the determined actual output value of the base voltage, and the optimal voltage multiplying relationship of the each base voltage comprises:
bucking and regulating, by the main control unit, the first base voltage or the second base voltage and converting the bucked and regulated first base voltage or the bucked and regulated second base voltage into the third base voltage, wherein a voltage difference between an actual output value of the third base voltage and the actual output value of the first base voltage or the second basic voltage is larger than a preset range.
