Abstract

The invention discloses a backlight module group, a scanning drive method for the backlight module group, and a display device, and belongs to the technical field of display. The backlight module group comprises a plurality of light emitting regions, a scanning drive module and a data updating module, wherein each of the light emitting regions at least comprises one light emitting unit. The scanning drive module and the data updating module are electrically connected to the light emitting units. The scanning drive method of the backlight module group includes a scanning drive phase and a plurality of data updating phases. At the scanning drive phase, the scanning drive module provides a scanning drive signal to the light emitting regions; in the data updating phases, the data updating module provides a data updating drive signal to the light-emitting regions, wherein the working time periods of the data updating phases at least partially overlap with the working time period of the scanning drive phase. The method can improve the backlight scanning frequency while reducing the power consumption of the backlight module group, improves the backlight flicker caused by the data updating, and improves the light-emitting effect and the light-emitting quality of the backlight module group.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a backlight module, a scanning driving method for the backlight module, and a display device. Background technique [0002] With the development of display technology, liquid crystal displays are used more and more widely. The combination of backlight and liquid crystal display constitutes a liquid crystal display module. The backlight module is one of the key components of the liquid crystal display panel, and its function is to supply sufficient brightness. And evenly distributed light source, so that it can display images normally. Backlight modules in the prior art are generally divided into two types: edge-lit backlight modules and direct-lit backlight modules. , has the characteristics of light weight, thin profile, narrow frame, and low power consumption. The spontaneous light source of the direct-type backlight module is placed directly below the light...
