1. A display driving method for driving a display panel, wherein the display panel comprises a base substrate and a plurality of pixel cells arranged on the base substrate, the plurality of pixel cells being arranged in arrays in a row direction and a column direction, wherein at least part of the plurality of pixel cells comprise anti-view sub-pixels, each of the anti-view sub-pixels comprising a first anode, an anti-view light-emitting part and a cathode, wherein at least part of the anti-view light-emitting parts have different areas of orthographic projection on the base substrate,
wherein the display panel further comprises a first transistor, a control line, a first power line and a second power line, a control terminal of the first transistor being connected to the control line, a first terminal of the first transistor being connected to the first power line, a second terminal of the first transistor being connected to the first anode, and the cathode being connected to the second power line, wherein the display driving method comprises:
acquiring a display mode of the display panel, the display mode comprising an anti-view mode and a wide viewing angle mode; and
controlling the control line to output a control signal to turn on the anti-view sub-pixels when the display mode of the display panel is determined as the anti-view mode;
wherein an area of an orthographic projection of each anti-view light-emitting part in an odd row on the base substrate is smaller than an area of an orthographic projection of each anti-view light-emitting part in an even row on the base substrate, wherein the first power line comprises a first power branch line and a second power branch line, wherein the first terminal of the first transistor in the odd row is connected to the first power branch line, and the first terminal of the first transistor in the even row is connected to the second power branch line, wherein the display driving method further comprises:
controlling the first power branch line and the second power branch line to output different voltages when the display mode of the display panel is determined as the anti-view mode;
wherein the anti-view mode comprises a normal light anti-view mode and a flashing anti-view mode, and controlling the first power branch line and the second power branch line to output different voltages when the display mode of the display panel is determined as the anti-view mode comprises:
controlling the first power branch line and the second power branch line to output signals with opposite waveforms when the display mode of the display panel is determined as the flashing anti-view mode.
