Display panel, display device, and display driving method

A display device, comprising:

• a display panel including a plurality of pixels arranged in a matrix form, each of the plurality of pixels including N subpixels arranged in a first direction and having different colors, wherein N is 3 or 4 and a plurality of sensing lines disposed in a second direction between the plurality of pixels and configured to sense characteristic values for a plurality of subpixels electrically connected thereto wherein the N subpixels are disposed so that subpixels of a same color are symmetrical with respect to the sensing line;
• a data driving circuit configured to supply a data voltage to the display panel and sense the characteristic values for the plurality of subpixels through the plurality of sensing lines;
• and
• a timing controller configured to control the data driving circuit and apply compensation image data to a corresponding subpixel using the characteristic values sensed by the data driving circuit,
• wherein the data driving circuit is configured to:
• initialize the sensing line to a reference voltage;
• and
• track the sensing line to sense a characteristic value charged to the sensing line after a predetermined time.

A method for driving a display device including a plurality of pixels arranged in a matrix form, the method comprising:

• disposing subpixels of a same color among a plurality of subpixels included in the plurality of pixels to be symmetrical with respect to a sensing line disposed between the plurality of pixels;
• simultaneously sensing characteristic values for the subpixels of the same color to which the sensing line is connected;
• averaging the characteristic values for the subpixels of the same color;
• and
• compensating for a characteristic value for a subpixel of a corresponding color using the average value of the characteristic values,
• wherein the sensing includes:
• initializing the sensing line to a reference voltage;
• and
• tracking the sensing line to sense a characteristic value charged to the sensing line after a predetermined time.
