Abstract

A display device includes a display panel, a backlight module, and a backlight control circuit. The backlight module is electrically connected to the display panel to provide a backlight for the display panel. The backlight module further includes a plurality of backlight driving circuits. The backlight control circuit is electrically connected to the backlight module, and the backlight control circuit is configured to control the backlight module and operate in one of a first display mode and a second display mode.

Description

technical field [0001] The invention relates to a display device and a backlight driving method, in particular to a display device and a backlight driving method for rapidly switching the brightness of the backlight. Background technique [0002] Today's display panels mostly use passive light-emitting technology, which uses the action of the liquid crystal to block or open the light of the backlight module to display the picture. Since the transition of the liquid crystal takes time, the response speed of the liquid crystal and the turn-on time of the backlight module are different in the display panel. It has always been a problem that needs to be solved in the technical field. Especially in the game scene or when testing the display panel, it may happen that the backlight module needs to be turned on quickly. However, the conventional backlight driving technology cannot turn on the backlight module quickly, so the desired effect cannot be achieved. Contents of the inven...
