Abstract
A voltage regulation method is provided and includes the following steps. A plurality of fixed voltages is provided to a gray-level resistor string, and a plurality of gray-level voltages and the fixed voltages are divided into a first voltage group and a second voltage group according to signal-to-noise ratios of the gray-level values. It is to determine whether the regulated fixed voltage is used to regulate a gray-level voltage corresponding to low gray-level value according to different voltage group. When the regulated fixed voltage is used to regulate the gray-level voltage corresponding to low gray-level value, it is determined whether the fixed voltage is regulated again by measuring a luminance value of a gray-level voltage having higher signal-to-noise ratio.
