Display device and source driver

A display device, comprising:

• a display panel having m data lines and n gate lines (m being a multiple of 12 greater than or equal to 24, and n being an integer of 2 or greater), and m×n pixel units provided in a matrix at respective intersections between the m data lines and the n gate lines;
• a gate driver configured to supply scan signals that control the pixel switches to be ON during a selection period based on a pulse width to the n gate lines;
• a source driver group that is constituted of 2j source drivers (j being an integer of 2 or greater) arranged along a lengthwise direction of the gate lines, and that is configured to receive one frame of an image data signal formed by a sequence of a plurality of pixel data piece groups that each include m/2 pixel data pieces that each cover R, G, and B pixels and to generate gradation voltage signals to be supplied to the m×n pixel units on the basis of the image data signal;
• j data supply lines provided in common among pairs of adjacent source drivers that constitute the source driver group;
• and
• a display controller that is connected to the 2j source drivers via the j data supply lines, and that is configured to output the image data signal to the j data supply lines for each of pixel data piece groups formed by sequentially splitting the m/2 pixel data pieces into j groups,
• wherein the pair of source drivers is constituted of a (2k−1)th source driver and a (2k)th source driver (k being a natural number of (j−1) or less), and
• wherein the (2k)th source driver receives m/(4j) pixel data pieces from the display controller via a data supply line, receives three pixel data pieces that cover the R, G, and B pixels of a (2k+1)th source driver that is adjacent to the (2k)th source driver and that is connected to the display controller via a differing data supply line, and generates m/(2j) of the gradation voltage signals on the basis of the m/(4j) pixel data pieces and the three pixel data pieces.
