Embodiment 1

[0020] refer to figure 1 , this embodiment provides a driving method for driving a backlight source, and the backlight source is used for providing backlight for a liquid crystal display panel. The driving method includes the following steps.

[0021] Step S1, acquiring parameters of the frame period of the picture currently displayed on the liquid crystal display panel, wherein the parameter represents the duration of the frame period, and the parameter is a dynamically changing value.

[0022] That is, when the liquid crystal display panel is displaying, the duration of each frame is dynamically changed. The parameters characterizing the duration are, for example, the duration of the frame period and the frame frequency. In one case, when driving a certain liquid crystal display panel for display, the duration of the line period is fixed, and the number of line periods (also called Vblk number) included in a frame period can be used to represent the duration of the frame p...

Embodiment 2

[0034] refer to figure 2 , the present embodiment provides a driving device for driving a backlight, and the backlight is used for providing a backlight for a liquid crystal display panel, and the driving device includes: an acquisition unit 101 for acquiring parameters of a frame period of a picture currently displayed by the liquid crystal display panel , wherein, the parameter characterizes the duration of the frame period, and the parameter is a dynamically changing value; the determination unit 102 is used to determine the corresponding brightness of the backlight according to the preset rules according to the acquired parameters of the frame period; the drive unit 103 is used to determine the corresponding brightness according to the determined The brightness determined by the unit drives the backlight to emit light of the corresponding brightness.

[0035] The acquisition unit 101 includes, for example, a port for communication with, for example, a graphics processing ...

Embodiment 3

[0038] see image 3 , this embodiment provides a driving device for driving a backlight, the backlight is used for providing a backlight for a liquid crystal display panel, the driving device includes a memory 401 and a processor 402, the memory 401 stores instructions, and the processor 402 is used to run the instructions to The driving method according to Embodiment 1 of the present invention is executed.

[0039]Specifically, the memory 401 is, for example, a device capable of storing instructions, such as a random access memory (RAM) or a read only memory (ROM). The processor 402 is, for example, a central processing unit (CPU) and other devices that perform computation and control.

Abstract

The invention provides a driving method, a driving device and a display device, belonging to the field of display technology, which can at least partly solve the problem of the flickering screen of the existing liquid crystal display device. The driving method of the present invention is used to drive a backlight, and the backlight is used to provide a backlight for a liquid crystal display panel, and the driving method includes: step S1, obtaining parameters of the frame period of the picture currently displayed by the liquid crystal display panel , wherein the parameter represents the duration of the frame period, and the parameter is a dynamically changing value; step S2, according to the obtained parameter of the frame period, determine the corresponding brightness of the backlight according to preset rules .

Description

technical field [0001] The invention belongs to the field of display technology, and in particular relates to a driving method, a driving device and a display device. Background technique [0002] When the existing liquid crystal display device is displaying, in some application scenarios (such as G-Sync), the calculation time required for different frames of images is different, which leads to the dynamic change of the frame period for displaying each frame of images of. A frame period generally includes a scanning phase and a holding phase, in which the progressive scanning of the liquid crystal display panel is completed, and in the holding phase the liquid crystal display panel maintains its written data voltage. The duration of the scanning phase in each frame period is fixed, which is to facilitate the design of the liquid crystal display panel and the corresponding driving device, and the duration of the holding phase can be dynamically adjusted according to the dura...
