Display panel, method for driving the same, and display device

A method for driving a display panel, the display panel comprising:

• a pixel circuit;
• and
• a light-emitting element electrically connected to the pixel circuit,
• wherein at least one light-emitting phase of the light-emitting element comprises n light-emitting sub-phases, and the pixel circuit is configured to transmit a light-emitting signal to the light-emitting element during the n light-emitting sub-phases;
• and
• wherein a duration ti of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in an ith light-emitting sub-phase of the n light-emitting sub-phases is smaller than a duration tj of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in a jth light-emitting sub-phase of the n light-emitting sub-phases, where 0<ti, 0<tj, 1≤i≤n, 1≤j≤n, and i≠j,
• the method comprising:
• acquiring a target display mode of the display panel;
• determining, according to the target display mode, a total duration of transmitting a light-emitting signal to the light-emitting element by the pixel circuit in a light-emitting phase and a number of light-emitting sub-phases in the light-emitting phase;
• determining an average duration of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in all light-emitting sub-phases of the light-emitting phase according to a ratio of the total duration of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in the light-emitting phase to the number of the light-emitting sub-phases in the light-emitting phase;
• and
• maintaining the duration of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in the first light-emitting sub-phase of the light-emitting sub-phases unchanged, and adjusting the durations of transmitting the light-emitting signal to the light-emitting element by the pixel circuit in other light-emitting sub-phases so that brightness of the light-emitting element in any two light-emitting sub-phases of the light-emitting sub-phases corresponds to a flicker value smaller than or equal to a preset value.

A display device, comprising a display panel, wherein the display panel comprises:
