Abstract: The disclosure is related to a light guide plate having a light-emitting surface, wherein a plurality of V-shaped grooves is formed on the light-emitting surface; each of the V-shaped grooves extends along a curved path. The V-shaped grooves of the light guide plate extend along the curved path to avoid the light guide plate from collecting light in a single direction. The interference fringes of the light guide plate are reduced, thereby improving the uniformity of light emission of the light guide plate.

Abstract: The disclosure is related to a backlight module comprising a light guide plate, a light source assembly and a frame. The frame surrounds the light guide plate. The light source assembly is arranged between the light incident surface of the light guide plate and the frame. The light source assembly comprises a substrate, a light emitting body and a transparent body. The transparent body packages the light emitting body on the substrate. The outer surface of the transparent body facing the light emitting body is a light emitting surface having a groove formed thereon facing the light incident surface of the light guide plate. The groove enables the light emitted from the transparent body to congest toward the direction of the center of the light guide plate to increase the optical coupling efficient of the backlight module. The disclosure further provides a liquid crystal display device.

Abstract: The disclosure provides a trichromatic illuminating module, comprising a circuit board and multiple illuminating units disposed on the circuit board. Each illuminating unit comprises a red chip, a green chip and a blue chip disposed on the circuit board, and intervals are set therebetween, a voltage is applied to the circuit board for illuminating the red chip, the green chip and the blue chip. There are more red chips than green chips and blue chips in each illuminating unit. Thus, the ratio of red light is increased. Since red light has the highest color gamut in the three primary colors, which causes it difficult for the saturation of color gamut. However, the ratio of red light of the disclosure is increased, such that the color saturation of white light emitted from the trichromatic illuminating module is increased. The disclosure also provides a backlight module and a liquid crystal display device.

Abstract: A quantum dot diaphragm is disclosed. The quantum dot diaphragm comprises a color gamut conversion region and a color gamut non-effective region surrounding the color gamut conversion region, wherein the color gamut non-effective region is provided with a quantum phosphor layer. According to the present disclosure, the color gamut non-effective region is provided with the quantum phosphor layer, so that the technical defect that an area of the diaphragm along the cutting line would become useless when the diaphragm is cut can be eliminated, and a color gamut conversion function of the quantum dot diaphragm can be further improved. The manufacturing procedure of the quantum dot diaphragm according to the present disclosure is simple. After the quantum dot diaphragm is cut, the color gamut non-effective region of the quantum dot diaphragm could be coated with the quantum phosphor, and then the quantum dot diaphragm needs to be assembled to the module product, so that the electronic products with high color gamut can be obtained.
