    Abstract: A display panel includes a plurality of pixels and an electrostatic circuit. At least one pixel includes: a pixel electrode; a common electrode; a light-emitting element; and a driving sub-circuit coupled to a scanning signal terminal, a data signal terminal, a light-emitting control signal terminal, a first voltage signal terminal and a first terminal of a light-emitting element, and outputs a first voltage signal from the first voltage signal terminal to the light-emitting element controlled by a scanning signal, a data signal, and a light-emitting control signal. The electrostatic circuit couples a first signal line and a second signal line, the first signal line receives a second voltage signal, and the second signal line receives a third voltage signal and is arranged on a periphery of the plurality of pixels. Common electrodes of the pixels are coupled to each other and to the second signal line.

    Abstract: The present application provides a display panel, a method of driving the same and a display apparatus. The display panel has pixel regions, each of which has pixel structures. Each of the pixel structures includes an anode, a cathode and a light emitting layer. The display panel further includes a controller and power signal lines coupled to the controller. Cathodes or anodes in a same pixel region are coupled to a same power signal line. The controller is configured to control a duty cycle of a control signal input to a power signal line coupled to a pixel region in response to a motion picture being displayed in the pixel region.

    Abstract: The present disclosure provides a fingerprint identification device, a touch panel, an input device and a fingerprint identification method. The fingerprint identification device includes a fingerprint identification module, gate lines and signal lines. The gate lines and the signal lines cross so as to define a plurality of sensing regions including a thin film transistors and a sensing electrode connected to the thin film transistors. A gate electrode of the thin film transistor is connected to the corresponding gate line, a source electrode is connected to the corresponding signal line, and a drain electrode is connected to the corresponding sensing electrode. The signal lines include signal-transmitting lines and signal-receiving lines, the sensing electrodes include transmitting electrodes and receiving electrodes. An electric field is generated between the transmitting electrode and the receiving electrode adjacent to the transmitting electrode, and a direction of the electric field is from the transmitting electrode to the receiving electrode adjacent to the transmitting electrode. The fingerprint identification module is connected to the signal-receiving lines, and determines, by detecting the intensity of the electric field when a finger is in the electric field, a fingerprint of the finger.
