Abstract
A buffer circuit, a display module, and a display driving method are disclosed. The buffer circuit comprises a positive polarity buffer, a negative polarity buffer. The positive polarity buffer receives a first supply voltage and a second supply voltage to output a positive reference voltage to a positive resistance string. The second supply voltage is less than the first supply voltage. The negative polarity buffer receives the second supply voltage and a third supply voltage to output a negative reference voltage to a negative resistance string. The third supply voltage is less than the second supply voltage.
