Driving method and system of display assembly, and display device

A driving, system of a display assembly using a driving method of the display assembly, the driving system comprising a driving circuitry of a display panel and a driving circuitry of a backlight module that is synchronously driven with the display panel;

• the backlight module comprises a plurality of independently controlled light sources, comprising a first color light source, a second color light source, and a third color light source;
• a corresponding light source brightness of the first color light source is a first brightness value, a corresponding light source brightness of the second color light source is a second brightness value, and a corresponding light source brightness of the third color light source is a third brightness value;
• wherein the driving circuitry of the display panel comprises:
• a receiver, configured for receiving a first color signal corresponding to the display panel, converting the first color signal into first brightness normalized signals, and converting the first brightness normalized signals into a first HSV (hue, saturation, value) signal;
• an adjuster, configured for adjusting a first saturation signal of the first HSV spatial signal using a preset adjustment coefficient to obtain a second saturation signal;
• a converter, configured for converting the second saturation signal into a second color signal;
• and
• a driver, configured for driving the display panel using the second color signal;
• wherein driving circuitry of the backlight module comprises:
• a light source receiver, configured for receiving the first color signal corresponding to the display panel, and obtaining the first saturation signal and the second saturation signal;
• a light source determiner, configured for determining a minimum color light source among the first color light source, the second color light source, and the third color light source, and obtaining a light source adjustment coefficient corresponding to the minimum color light source based on the first saturation signal and the second saturation signal;
• and
• a light source adjuster, configured for adjusting the minimum color light source using the light source adjustment coefficient to obtain a fourth brightness value;
• and
• a light source driver, configured for driving the minimum color light source using a fourth brightness value.
