Abstract: The present disclosure discloses a backlight module and a display device. The light emission direction of at least one of the lamp source and the fluorescent film is provided with a diffusely reflecting layer. The diffusely reflecting layer arranged above the lamp source diffusely reflects pump light emitted from the lamp source, which may enhance uniformity of the pump light. The diffusely reflecting layer arranged above the fluorescent film scatters light emitted from the fluorescent film, scatters the light and distributes the light to a larger range, which may improve light mixing uniformity and improve the uniformity of light emission brightness.

Abstract: A light valve device includes a driving substrate having a shading zone and a photic zone. A shading unit includes a first shading plate, two driving devices, and second shading plates respectively connected to the two driving devices. The driving devices and the first shading plate are fixed in the shading zone adjacent to the driving substrate. The first shading plate is between the two driving devices. The driving devices are operable to drive the two second shading plates close to the first shading plate to make the second shading plates face the photic zone of the driving substrate for preventing light entering the driving substrate. By locating the light valve device under the sub pixel, the dynamic contrast can be raised to promote the display effect.

Abstract: The present invention provides a reflective liquid crystal display device, which includes an upper substrate and a lower substrate that are opposite to each other, a liquid crystal layer arranged between the upper and lower substrates, a transparent plastic layer bonded to a surface of the lower substrate that is distant from the liquid crystal layer, and a mirror-reflection layer that is attached by the transparent plastic layer to the surface of the lower substrate. The transparent plastic material of the transparent plastic layer for attaching the mirror-reflection layer contains therein transparent particles and the transparent plastic material and the transparent particles have different reflectivity so as to provide an effect of diffuse reflection. Namely, the transparent plastic layer and the mirror-reflection layer are combined together to provide a diffuse-reflection layer, so that compared to the conventional reflective liquid crystal display devices, there is no need to conduct an additional process for forming a diffuse-reflection layer, thereby simplifying the manufacturing of the diffuse-reflection layer and reducing the difficulty and cost of the manufacturing.
