Display panel, display device including the same, and method for operating the same

A display device comprising:

• a display panel including:
• a plurality of sub-pixels arranged in rows and columns;
• a plurality of scan lines arranged such that one scan line is disposed in each of the rows of the plurality of sub-pixels;
• a plurality of data lines arranged such that two data lines are disposed in each of the columns of the plurality of sub-pixels;
• a first multiplexer configured to select a data line at one side among the two data lines disposed in each column;
• a second multiplexer configured to select a data line at another side among the two data lines disposed in each column;
• each of first and second scan switches for switching the scan line disposed in each row connected to the data line at the one side disposed in each column;
• and
• each of third and fourth scan switches for switching the scan line disposed in each row connected to the data line at the another side disposed in each column;
• a scan driver for applying a scan signal to a plurality of gate lines;
• a data driver for applying a data signal to the plurality of data lines;
• a power supply for providing a high-potential voltage, a low-potential voltage, and an initialization voltage to each of the plurality of sub-pixels;
• and
• a timing controller for controlling the scan driver and the data driver,
• wherein pairs of the first and second scan switches and pairs of the third and fourth scan switches are alternatively arranged with each other in the column direction of the plurality of sub-pixels and in a zig-zag manner, and
• wherein the scan signal is applied to the plurality of scan lines such that writing and sensing operations of each of pixels of a first row, and an initialization operation of a light-emitting element and a gate electrode of a driving switch of each of pixels of a fifth row are simultaneously executed.

A method for operating a display device having a display panel that includes one scan line disposed in each of rows of a plurality of sub-pixels, and two data lines respectively disposed at one side and another side and in each of columns of the plurality of sub-pixels, the method comprises:

• (a) for a first half frame, turning a first multiplexer switch on to apply a data voltage to a sub-pixel corresponding to an odd-numbered scan line through the data line at one side;
• and
• (b) for a second half frame, turning a second multiplexer switch on to a data voltage to a sub-pixel corresponding to an even-numbered scan line through the data line at another side,
• wherein the scan signal is applied to the plurality of scan lines such that writing and sensing operations of each of pixels of a first row, and an initialization operation of a light-emitting element and a gate electrode of a driving switch of each of pixels of a fifth row are simultaneously executed.
