摘要： The present disclosure provides a display module and a display device including the same. The display module includes a backplate, an optical film, a quantum dot film, a phosphor layer, and a light source. The optical film is disposed on the backplate. The optical film has a light incident surface, a light emitting surface, and a first side surface. The first side surface is perpendicular to the backplate, and the light emitting surface is parallel to the backplate. The quantum dot film is disposed on the light emitting surface of the optical film. The phosphor layer is disposed on the first side surface of the optical film. The light incident surface of the optical film is located on the backplate in a light emission direction of the light source.

摘要： This invention provides a composite diffuser plate comprising a light-emitting layer for emitting light, a middle layer for guiding light, and a light-entering layer for entering light, being sequentially stacked downwardly. At least one surface of the middle layer is provided with an array of curved protrusions. Refractive indexes of the light-emitting layer, the middle layer and the light-entering layer are gradually increased. This invention further provides an ultra-thin direct type backlight module. In the composite diffuser plate of this invention, in addition to a gradual increase in refractive indexes of the light-emitting layer, the middle layer and the light-entering layer, the middle layer is provided with a microstructure having curved protrusions, which further enhances diverging effect of emitting angle. The direct-light TV can increase a light-emitting area with a small OD value, and thus improves a LED Mura problem, realizing a slim direct-light TV and enhancing market competitiveness.

摘要： Disclosed is a backlight module and a display module. The backlight module includes a backboard, a light bar, and an atomization layer. The backboard includes a bottom board, a plurality of side boards connected to the bottom board, and a top board connected to the plurality of side boards, and the plurality of side boards are enclosed to define a receiving chamber of the backboard. The light bar is located in the receiving chamber and is fixed at one side of the bottom board facing the top board. The atomization layer is located in the receiving chamber and is fixed at one side of the top board facing the bottom board. The atomization layer is capable of replacing the diffuser plate and the optical film in the current backlight module, thereby reducing the cost of the optical film and the diffuser plate.

摘要： This invention discloses a low-cost backlight module including a plurality of light source assemblies arranged in an array, and a reflector as well as a diffuser plate both disposed beside each light source assembly, wherein the reflector includes a circle of side reflection wall arranged annularly around the light source assembly, each of the light source assemblies includes a plurality of spot light sources spaced apart circumferentially and faced toward the side reflection wall, and the light emitted by the spot light source toward the side reflection wall is reflected by the side reflection wall and then emitted out from the diffuser plate. This invention further discloses a display device. An area of the diffuser plate that is emitted by each spot light source is enlarged and the emitted light becomes more uniform. The number of spot light sources is reduced and the problem of LED Mura is avoided.
