A method and an apparatus for driving a display panel, and a display device. A blank-display interval of the display panel is configured between a first display frame and a second display frame of the display panel. The blank-display interval includes a first target interval. During the first target interval, a voltage at a first electrode of each light-emitting element of the display panel is not initialized, and a voltage of a first reference voltage signal configured to initialize the voltage at the first electrode is changed.

Method and apparatus for driving display panel, and display device

Display panel, display module and driving method are provided. The display panel includes a power management chip, a power signal line loading an electrical signal based on the power management chip, a current detection module, a gate control module, and an optional load module. The gate control modules is connected between the optional load module and the power signal line, and the optional load module is controlled by the gate control module and connected to the power signal line. The current detection module is configured to detect a first current loaded on the power signal line and control the gate control module to be turned on to connect the optional load module to the power signal line when the first current is less than a set threshold.

Display panel, display module, and driving method

A display drive method is applied to a display panel. The display panel has a subpixel used for image display. The display drive method includes obtaining a to-be-displayed grayscale of a to-be-displayed subpixel, selecting a suitable compensation manner based on the to-be-displayed grayscale, and providing a data voltage for the to-be-displayed sub-pixel based on the selected compensation manner. The compensation manner includes a first compensation manner and a second compensation manner. When the to-be-displayed grayscale is 0 grayscale, the first compensation manner is selected. When the to-be-displayed grayscale is greater than 0 grayscale, the second compensation manner is selected. The first compensation manner is used to reduce a difference between light-emitting efficiencies of sub-pixels with different light-emitting colors under a same grayscale.

Display drive method for reducing difference between light emitting efficiencies of subpixels, display driver, and display device

Provided are a display panel, a method for the same and a display device. In the display panel, in a same shift register unit of a shift register circuit, a pull-down module is electrically connected to a first node, a second node, a first level signal terminal, and a signal output terminal separately. The pull-down module transmits a first level signal of the first level signal terminal to the second node and the signal output terminal under the control of a potential of the first node. The pull-down module includes at least a first transistor. A gate of the first transistor is electrically connected to the first node; the pull-down control module is electrically connected to the first node and the scanning control terminal separately; and the pull-down control module controls a scanning control signal of the scanning control terminal to be transmitted to the first node.
