Display apparatus and driving method thereof

A display apparatus comprising:

• a plurality of pixel units arranged in a matrix, each of the pixel units comprises a driving transistor;
• a plurality of horizontal scan lines in a display region, and configured to extend along a first direction;
• and
• a plurality of data lines in the display region, and configured to extend along a second direction perpendicular to the first direction;
• and
• wherein a plurality of pixel group are defined;
• each pixel group comprises at least three pixel units;
• the pixel units in a same pixel group are arranged on different columns along the first direction, and further arranged on different rows along the second direction, the driving transistors of the pixel units in the same pixel group are electrically connected to a same data line through connection lines;
• wherein the display region further comprises a plurality of vertical scan lines along the second direction;
• the display region further comprises a plurality of touch sensing lines;
• the display apparatus selectively operates under a display period and a touch period;
• the touch sensing lines, the data lines, and the vertical scan lines are patterned in the same metal layer;
• the touch sensing lines are parallel with data lines along the second direction;
• each touch sensing line is arranged between adjacent data lines;
• the touch sensing lines transmit touch sensing signals during the touch period.
