摘要： Disclosed is a display method of a multi-primary color sphere display device. The method includes the steps of: dividing a pixel color gamut into color patches; determining a color patch to which a pixel chromaticity coordinate belongs; displaying through three dynamic sub-pixels according to the color patch to which the pixel chromaticity coordinate belongs; and determining output brightness of the dynamic sub-pixels by coordinates of a white point, coordinates of the dynamic sub-pixels, an output brightness value when gray level 255 in red is input, an output brightness value when gray level 255 in green is input, and an output brightness value when gray level 255 in blue is input respectively. When input gray level values of RGB three pixels are approximately the same, output brightness and white chromaticity are basically close to the same, guaranteeing the consistency of the chromaticity coordinates of the white point.

摘要： The present disclosure teaches a graphene backlight module and a liquid crystal display (LCD) device including the backlight module. The backlight module includes a lower substrate, a number of graphene sources, a number of graphene drains, a graphene light generation layer, a first insulating protection layer, a number of graphene gates, and a second insulating protection layer. Graphene is used to make the gates, sources, drains, and the light generation layer of the backlight module. The graphene backlight module therefore functions both as a lighting unit and a driving unit to the liquid crystal, thereby simplifying the LCD device's structure and manufacturing process. In addition, as there is no need for the light guide plate and optical films required by conventional backlight modules, the thinning of the LCD device is achievable.
