Abstract
A reference voltage generation circuit is provided. The reference voltage generation circuit reduces a potential difference between a reference voltage less than a first data driving voltage and a data driving voltage, namely, the potential difference between a lower reference voltage and the data driving voltage is reduced. Therefore, the power loss of a voltage dividing module is reduced to prevent the problems of reduced reliability and reduced service life of a drive circuit board due to excessive internal temperature.
