摘要： A display substrate includes an insulating substrate, a first gate line (GL1), a first lower electrode (113_1), a second lower electrode (113_2), a first upper electrode (114_1), and a second upper electrode (114_2). The insulating substrate includes a first pixel region (PA1) and a second pixel region (PA2) located along a first direction (D1) from the first pixel region (PA1). The first gate line (GL1) extends in a second direction (D2) crossing the first direction (D1) on the insulating substrate. The first and the second lower electrodes (113_1, 113_2) are in the first and the second pixel regions (PA1, PA2), respectively. The first upper electrode (114_1) overlaps the first lower electrode (113_1) in the first pixel region (PA1) and includes a first slit pattern (115_1) extending in at least one of a third direction and a fourth direction different from the first and the second directions (D1, D2), wherein the third direction is different from the fourth direction. The second upper electrode (114_2) overlaps the second lower electrode (113_2) in the second pixel region (PA2) and includes a second slit pattern (115_2) extending in at least one of fourth direction and the third direction. The second slit pattern (115_2) is symmetric to the first slit pattern (115_1) with respect to the second direction (D2).

摘要： A display device and a method for driving the same are provided by the present disclosure. The display device includes a display panel and a touch panel. The method includes: applying a horizontal synchronizing signal to a plurality of scanning lines of the display panel; and applying a touch driving signal to a plurality of touch driving signal lines of the touch panel; an orthographic projection of the scanning line receiving the horizontal synchronizing signal onto the display panel does not overlap an orthographic projection of the touch driving signal line receiving the touch driving signal onto the display panel at least within a predetermined time period. When the display device displays images within the predetermined time period, the scanning line receiving the horizontal synchronizing signal and the touch driving signal line receiving the touch driving signal are staggered, so capacitive coupling may hardly be generated between them, thereby a signal-noise ratio of the touch panel within the predetermined time period may be improved.
