The present invention provides a display panel and an electronic apparatus, including a first display part and a second display part, a plurality of second gate driving units electrically connected to the second display part and arranged in cascade, a plurality of first gate driving units electrically connected to the first display part and arranged in cascade. A first gate driving unit including a first output unit for transmitting a first voltage to an output terminal in response to a voltage of a first node, a second output unit for transmitting a second voltage to the output terminal in response to a voltage of a second node, an output terminal electrically connected to a corresponding first sub-pixel, a constant voltage control unit electrically connected to a first node or a second node.

Display panel and electronic apparatus

A gate drive circuit and a display panel. The gate drive circuit includes one or more shift register groups. Each of the shift register groups includes N shift adjacent registers that output in sequence, with N being an integer greater than or equal to 3. Each of the shift registers includes a first output stage and a frequency division control module. The first output stage is configured to output a gate drive signal. The frequency division control module is configured to control outputting of the gate drive signal based on a refresh frequency. A control end of each frequency division control module in each of the shift register groups receives a control signal with a different phase and a same frequency, respectively, to adjust a pulse width of the gate drive signal and maintain a same pulse width at different refresh frequencies.

Gate drive circuit and display panel

The present application discloses a display panel in which a second data line in a display area is located between a first data line and a third data line, and a spacing between the first data line and the second data line is less than a spacing between the third data line and the second data line. A second pad is located between a first pad and a third pad in a direction perpendicular to the display area pointing to a binding area, the first pad is electrically connected to the first data line, the second pad is electrically connected to the third data line, and the third pad is electrically connected to the second data line.

Display panel

A display including a pixel circuit is provided. The pixel circuit includes a driving transistor, a writing transistor connected in series between a data line and the second node or the third node, an initialization module, and a compensation transistor connected in series between the first node and the second node or the third node. In the driving transistor, a gate is connected to the first node, a first electrode is connected to the second node, and a second electrode is connected to the third node. A gate of the writing transistor is connected to a scanning signal. The initialization module is connected to the first, second, and/or third nodes to perform resetting. The compensation transistor remains a turned-on state in only one continuous time period in each frame, and the initialization module and the writing transistor turn on in a time-sharing manner in the continuous time period.
