Abstract

The invention provides a dynamic backlight control method, a dynamic backlight module, a display device and a storage medium, a lamp bead of the dynamic backlight module comprises a green chip and atleast two blue chips. The dynamic backlight control method comprises the following steps: receiving an information source signal; and when the signal source signal is a pure blue signal, closing the green chip, and driving two or more blue chips to output blue light. According to the invention, the overall brightness of the blue field can be improved, and color coordinate deviation caused by brightness improvement is avoided, so that the blue dot color purity is ensured.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a dynamic backlight control method, a dynamic backlight module, a display device and a storage medium. Background technique [0002] The backlight methods of LCD screens include static backlight and color dynamic backlight, and color dynamic backlight includes blue-green dynamic backlight, red-green-blue RGB dynamic backlight, etc. Among them, the static backlight means that the backlight is white; the color dynamic backlight means that different color chips are used together to emit light (sometimes phosphor powder is also used). [0003] Compared with the static backlight, the color dynamic backlight can guarantee the color purity of the blue point when the blue field signal needs to be output; but because the green light is suppressed, the brightness will be reduced, which cannot meet the viewing needs of users. Contents of the invention [0004] The main purpose of the p...
