A display device and an OLED display panel thereof. The OLED display panel includes a non-transparent display area including first OLED pixels, a transparent display area including second OLED pixels, a display driving chip, a first gate driving circuit group. For a same of image, a pulse width of the second gate driving signal for the second OLED pixels is substantially the same as a pulse width of the first gate driving signal for the first OLED pixels; and intersection points of a boundary line and a pixel row where the first OLED pixels in a specified row are located falls within a range of intersection points of the boundary line and a corresponding pixel row of the second OLED pixels.

Display device and OLED display panel thereof

A method for driving a display panel includes controlling a signal of ON/OFF state of a switch in a Demux circuit as a switch signal, and dividing each rising time period in the switch signal into two phases (T, T), so that the abrupt change effect of voltage generated on both side positions of the display panel and a middle position of the display panel is relatively uniform, ensuring that the charging effect of the display panel at different positions is substantially the same, the brightness of the display panel is even after being driven, and the problem of bright lines in the column direction of the display panel is effectively improved.
