Abstract
A display device comprises a plurality of pixel unit sets and a plurality of common electrode (VCOM) signal generation circuits. Each of the pixel unit sets comprises a first portion pixel unit and a second portion pixel unit. Each of the first portion pixel unit and each of the second portion pixel unit comprise a plurality rows of pixel units. Each row of the pixel units comprises a plurality of pixel units. The VCOM signal generation circuits are respectively coupled to one of the pixel unit sets. The VCOM signal generation circuits are divided into a plurality of groups of number m. The VCOM signal generation circuits in each of the groups generate a first VCOM signal and a second VCOM signal to the coupled pixel unit set according to a first clock signal, a second clock signal and one of a plurality control signal sets of number m.
