1. A display panel with anti-view pixel driving circuits connected to sub-pixel driving circuits to prevent peeping under wide view angles, comprising:
a plurality of sub-pixel driving circuits each of which is electrically connected to at least one scan line; and
a plurality of anti-view pixel driving circuits each of which comprises an anti-view light-emitting diode and an anti-view switch tube for controlling an on and off of the anti-view light-emitting diode, the plurality of anti-view pixel driving circuits being respectively connected to the plurality of sub-pixel driving circuits such that a control end of the anti-view switch tube of each anti-view pixel driving circuit shares a scan line with a corresponding sub-pixel driving circuit, wherein scanning signals are input to scan lines of at least two sub-pixel driving circuits at different times during a line scanning process, such that the scanning signals are input to the control ends of the anti-view switch tubes of at least two anti-view pixel driving circuits at different times;
wherein each sub-pixel driving circuit is electrically connected to a first scan line and a second scan line, and the scanning signals are input to the first scan line and the second scan line at different times during the line scanning process to create a flickering effect from the anti-view pixel driving circuits;
the control ends of the anti-view switch tubes of a part of the plurality of anti-view pixel driving circuits share the first scan line with the plurality of sub-pixel driving circuits corresponding to the part of the plurality of anti-view pixel driving circuits, and the control ends of the anti-view switch tubes of the other part of the plurality of anti-view pixel driving circuits share the second scan line with the plurality of sub-pixel driving circuits corresponding to the other part of the plurality of anti-view pixel driving circuits.
