    Abstract: The invention provides an optical film assembly, a backlight module, and a display device. The backlight module includes a light source emitting at least a first light, a first optical film, and a second optical film laminated to the first optical film, wherein the first optical film includes a functional layer but does not include a base film, the functional layer is a diffusion film, a brightness enhancement film, a reflection film, or a prism film, and the second optical film is a light conversion layer, the light conversion layer receives the first light and converts the first light to at least a second light to emit, such that a light emission angle of the backlight module matches a requirement of wide viewing angle. The invention could broaden the light emitting angle of the backlight module to make the display device with the backlight module achieve wide viewing angle.

    Abstract: The present invention discloses an optical testing device includes a base, a holder, and a number of illuminating modules. The base defines a sliding groove extending along a first direction in a top surface thereof. The holder slides along a second direction on the top surface of the base. The interval regulator is connected to the holder. The illuminating modules are slidably received in the sliding groove. Each of the illuminating modules comprises a circuit board and a single lighting element set on the circuit board. The interval regulator drives the holder to slide along a second direction so that a distance between the holder and the illuminating modules is regulated. The first direction is not parallel to the second direction.

    Abstract: The present disclosure provides a light source component, which includes a power supply plate; at least two point light sources disposed on the power supply plate; and a reflective block disposed on the power supply plate and between two point light sources adjacent to each other, wherein the reflective block is used to reflect light emitted from the point light sources thereto along a direction away from the power supply plate. The present disclosure further provides a backlight module and a liquid crystal display with the light source component. The present disclosure can reduce the amount of the point light source used and save the cost significantly when manufacturing point light sources of the same number by disposing a reflective block which serves equivalently as a point light source between the point light sources.

    Abstract: The present application discloses a backlight module and a display device, the backlight module including a light source for emitting at least a first light; at least two sheets of light conversion films, wherein at least one sheet of light conversion films receives the first light and converts the light into at least a second light to emit, and makes the light emitting angle of the backlight module matching the wide viewing angle display requirements. It can increase the light emitting angle of the backlight module and achieve the wide viewing angle effect. By having at least two sheets of light conversion films at the same time, a part of the light is reflected back while the light is scattered and emitted at the same time, and the light is excited and emitted again, to improve the light utilization rate, enhance the brightness to have a better performance of display.
