Abstract: The present disclosure relates to liquid crystal display technology, and more particularly to a double-sided display. The double-sided display includes a first display panel, a second display panel parallel to the first display panel, and a backlight module between the first display panel and the second display panel. The backlight module includes a first optical film and a second optical film respectively arranged at internal sides of the first display panel and the second display panel, and a light guiding layer between the first optical film and the second optical film. The light guiding layer includes a first dot reflective layer and a second dot reflective layer parallel to each other, at least one light reflecting component and a light source arranged within the light reflective component. The first dot reflective layer, the second dot reflective layer and the light reflective components cooperatively form a light guiding chamber. The double-sided display includes the edge-type backlight without adopting a light guiding plate. The light beams may be guided via the air such that the double-sided display may be thinner and lighter.

Abstract: Disclosed is a display method of a multi-primary color graphene 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.
