    Abstract: A touch structure includes an insulating layer, first touch electrodes, second touch electrodes, and dummy electrodes that are insulated from each other. The second touch electrode includes second touch sub-electrodes and bridge portions, and every two adjacent second touch electrodes are electrically connected via a bridge portion. The second touch sub-electrodes and the bridge portions are disposed on two opposite sides of the insulating layer, and the second touch sub-electrodes and the first touch electrodes are disposed on a same side of the insulating layer. The dummy electrodes and the bridge portions are disposed on a same side of the insulating layer. Orthographic projections of the dummy electrodes on the insulating layer do not overlap with orthographic projections of the first touch electrodes and the second touch electrodes on the insulating layer.

    Abstract: A pixel driving circuit and a method for driving the same, a display panel, and a display apparatus are disclosed. The pixel driving circuit includes: a driving transistor, an organic light emitting diode, a light emitting control sub-circuit, a first scanning sub-circuit, a second scanning sub-circuit, a first storage sub-circuit, and a second storage sub-circuit. The light emitting control sub-circuit is configured to transmit a first voltage at a first voltage terminal to a second node under control of a light emitting control terminal. The first scanning sub-circuit is configured to cause a voltage at a first node to be equal to a voltage at the second node under control of a scanning signal terminal. The second scanning sub-circuit is configured to transmit a reference voltage at a reference voltage terminal to a third node under control of the scanning signal terminal. The first storage sub-circuit is configured to be charged or discharged under control of the second node and a data signal terminal. The second storage sub-circuit is configured to be charged or discharged under control of the first node and the third node.
