Abstract: The present invention relates to a display apparatus and a method for driving the same. The display apparatus comprises: a source driving circuit having at least one output; at least one pixel unit each including a plurality of sub-pixels, the respective sub-pixels in each pixel unit being connected to the same output of the source driving circuit by data lines, wherein a switch group is disposed in a data line connecting each sub-pixel with the output of the source driving circuit, each switch group including at least two switches parallel with each other; wherein the source driving circuit charges each pixel unit based on the on-off states of the respective switches between the source driving circuit and each pixel unit through a plurality of charging phases, wherein for one switch group corresponding to one of the sub-pixels in each pixel unit, each switch in the one switch group is respectively switched on in different charging phases to perform at least two times of charge on the one of the sub-pixels in at least two charging phases. The display apparatus and the method for driving the same can increase charging time for each sub-pixel, thus avoiding a bad display due to insufficient charge of the sub-pixels.
