## Abstract

A display panel includes a pixel block, a data circuit, and a data source. The pixel block includes a first sub-pixel coupled to a first data line, and N second sub-pixels. Each second sub-pixel of the N second sub-pixels is coupled to a corresponding second data line of N second data lines. The data circuit includes N switches. Each switch of the N switches is coupled to a corresponding second sub-pixel. When N voltage levels are sequentially outputted from the data source to the first data line and the N second data lines, the N switches are disabled sequentially.
