Abstract

The invention discloses a driving method of a backlight module, a field sequential display device and VR equipment. A specific implementation of the method includes: obtaining the user's eye blinking frequency per unit time; adjusting the refresh rate of the backlight module to an integral multiple of the eye blinking frequency; and driving the backlight module according to the adjusted refresh rate. This embodiment can adaptively adjust the refresh rate of the backlight module in real time according to the blinking frequency of the user, so as to ensure that the pictures seen before and after the user closes the eyes during the blinking action when watching the picture correspond to the light source of the same color, thereby avoiding the light source caused by the user Visual color confusion caused by blinking improves the display effect and viewing experience.

Description

technical field [0001] The invention relates to the field of display technology. More specifically, it relates to a driving method of a backlight module, a field sequential display device and a VR device. Background technique [0002] At present, the main structure of a liquid crystal display device is a liquid crystal display panel, and the liquid crystal display panel includes an upper substrate and a lower substrate of a cell, and liquid crystals filled between the upper substrate and the lower substrate. The liquid crystal display device also includes a driving circuit for driving the liquid crystal display panel, a backlight module for providing a surface light source for the liquid crystal panel, a driving circuit for driving the backlight module, and a control module for controlling the two driving circuits. Modules such as MCU microcontrollers. Among them, the liquid crystal display device implements color display methods into RGB three primary colors (red, green, ...
