Problems solved by technology

In order to improve the display color gamut of display devices, quantum dot films are generally packaged on optical films such as polarizers or reflectors. This method will also increase the thickness of the reflector and the entire display device, which is not conducive to the thinness of the display device. change

Embodiment Construction

[0016] see figure 1 , figure 1 It is a structural schematic diagram of an embodiment of the reflective sheet of the present invention. The reflective sheet 101 of this embodiment is used to reflect the incident light irradiated on the reflective sheet 101; the reflective sheet 101 includes at least an air bubble layer 102 and a first film layer 103, and the first film layer 103 is arranged on the non-light-incident side of the air bubble layer 102 surface for diffusely reflecting incident light, wherein the bubble layer 102 includes a plurality of embedded bubbles 104 and quantum dots 105, and the quantum dots 105 generate light with a wavelength different from that of the incident light when excited by the incident light.

[0017] The thickness dimension of the reflective sheet 101 is negligible relative to the surface size of the light-incident side. Therefore, the light-incident side of the reflective sheet 101 in this embodiment is its light-exit side, and the light-incid...

Abstract

The invention discloses a reflector plate and a manufacturing method thereof and a backlight module. The reflector plate is used for reflecting incident light and at least comprises a bubble layer and a first film layer arranged on the surface of the non-light-inlet side of the bubble layer, wherein the bubble layer comprises multiple embedded bubbles and quantum dots, the quantum dots generate light with the wave length different from that of the incident light under excitation of the incident light, therefore, the display color gamut of emergent light of the reflector plate can be widened, and the thickness of the reflector plate and the backlight module can be decreased through the embedded bubbles and quantum dots.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a reflection sheet, a manufacturing method thereof, and a backlight module. Background technique [0002] The reflector is an important component of the display device, which can significantly improve the light utilization rate of the display device, increase the display brightness of the display device, and save electric energy. Quantum dots are quasi-zero-dimensional nanomaterials. By changing the size and chemical composition of quantum dots, the emission spectrum can cover the entire visible light region. Quantum dots have a wide and continuous distribution of excitation spectra, so the display of display devices can be greatly improved. color gamut. [0003] The inventors of the present invention have found in the long-term research and development that in the current prior art, in order to improve the light reflectivity of the reflective sheet, the concentration of inorga...
