摘要： A light guiding system includes an ambient light gathering system, multiple light guiding devices and a wedge light guiding bar. The ambient light gathering system facing ambient light is used for absorbing the ambient light. Each light guiding device absorbs the absorbed light. The wedge light guiding bar has a light-out surface and a light-in surface coupled to the light-out surface. The light-in surface is a wide surface coupled to an inclined surface. The light-out surface is opposite to the inclined surface and next to a light-in side of a light guide plate. The wedge light guiding bar for use in the light guiding system, an edge-lighting backlight module and an LCD device can reduce cost of material and weight. Also, the light uniformity of the light output end is improved and the optical quality of the edge-lighting backlight module is raised.

摘要： 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.

摘要： 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.
