A display method is applied to a display apparatus including a display panel, a display driver chip, and a microprocessor. The display method includes outputting, by the display panel, a scanning-done signal of a first frame image generated after scanning rows of pixel circuits of the display panel; after the microprocessor or the display driver chip receives the scanning-done signal, writing, by the display driver chip, initial data of a second frame image provided by the microprocessor and outputting, by the display driver chip, display data of the second frame image to the display panel based on the initial data; or outputting, by the display driver chip, the display data of the second frame image to the display panel in response to the scanning-done signal, the display data being generated based on the initial data provided by the microprocessor. The second frame image follows the first frame image.

Display method and display apparatus

The method includes, in a low-frequency driving mode where a keeping phase is arranged between two active phases, providing a light-emitting control signal with a duty cycle of a % to a pixel circuit during the active phase; and performing first and second switches on the light-emitting control signal during the keeping phase. The first switch is performed before the second switch. Panel brightness at the first switch is higher than panel brightness at the second switch. The duty cycle of the light-emitting control signal is b % after the second switch. b>a. A total duration of active levels of the light-emitting control signal within one frame after the first switch is between a total duration of active levels of the light-emitting control signal with the duty cycle of a % and a total duration of active levels of the light-emitting control signal with the duty cycle of b % within one frame.

Method for driving display panel, and display apparatus

The present disclosure relate to a driving method for a display panel, a display panel, and a display apparatus. The display panel includes a first mode, and a driving period in the first mode includes an active frame and a hold frame. The driving method includes: in the first mode, controlling a total light emission duration of a light emission control signal in two adjacent time units in the driving period to satisfy the following condition: where the time unit includes at least one light emission period, a first time unit at least partially overlaps with the active frame, Ndenotes a total light emission duration of the light emission control signal in the i-th time unit, Ndenotes a total light emission duration of the light emission control signal in the (i+1)-th time unit, i≥1, and A denotes a critical percentage threshold for brightness variation.

Driving method for display panel, display panel, and display apparatus

The display panel includes pixel groups including multiple sub-pixels; and driving signal lines. One driving signal line corresponds to at least one pixel group of the pixel groups, and multiple driving signal lines sequentially output a charging enabling level to drive corresponding pixel groups. The sub-pixel includes a first color sub-pixel that includes a first sub-pixel and a second sub-pixel. The first and second sub-pixels are arranged along an arrangement direction of the pixel group, and the second sub-pixel and the first sub-pixel are spaced by other first color sub-pixels whose number is not greater than a preset number. In a first mode, the display panel receives a noise signal, and a phase difference between charging enabling levels provided by the driving signal lines corresponding to the first sub-pixel and the second sub-pixel is non-integer times a noise cycle.
