Problems solved by technology

However, the current quantum dot film does not take into account the good protection of the edge when it is packaged, so that the edge position of the quantum dot film is easily affected by the external environment (such as moisture or dust) and the quantum conversion efficiency is reduced. As a result, an obvious aperture appears at the edge of the final light output, which in turn affects the overall backlight effect

Embodiment Construction

[0013] see Figure 1-2 , shows a backlight module 10 according to an embodiment of the present invention. The backlight module 10 includes a plurality of light sources 20 , a substrate 30 , a quantum dot film 40 formed on the substrate 30 , a cover plate 50 covering the quantum dot film 40 and a sealing layer 60 surrounding the quantum dot film 40 .

[0014] The light source 20 is made of semiconductor material, which can be excited by electric current to emit visible light. In this embodiment, the light source 20 includes a plurality of blue light emitting diodes. The LEDs are arranged in a row to emit light toward the side of the substrate 30 .

[0015] The substrate 30 is made of transparent materials such as glass, polycarbonate, and polymethyl methacrylate. The substrate 30 is a rectangular board, which includes a light incident surface 32 and a light exit surface 34 adjacent to the light incident surface 32 . In this embodiment, the light incident surface 32 is the s...

Abstract

The invention provides a backlight module. The backlight module comprises a light source, a substrate, a quantum dot film formed on the substrate and a cover plate covering the quantum dot film, as well as a sealing layer surrounding the quantum dot film; the sealing layer is connected with the substrate and the cover plate so that the quantum dot film can be sealed between the substrate and the cover plate. As the quantum dot film is sealed between the substrate and the cover plate by the sealing layer, the backlight effect of the backlight module is improved. The invention also discloses a manufacturing method of the backlight module.

Description

technical field [0001] The invention relates to a backlight module, in particular to a display backlight module and a manufacturing method thereof. Background technique [0002] The existing display is limited by the influence of the backlight source, and its color rendering index (color rendering index) is usually between 60 and 70, which is difficult to meet the requirement of high color reproduction. Therefore, the industry has designed a quantum dot film (quantum dot film) to improve the color rendering of the display. The quantum dot film can convert the light emitted by the backlight light source into light of different colors by quantum effect. As a result, the color rendering index of the display can reach a level higher than 70. However, the current quantum dot film does not take into account the good protection of the edge when it is packaged, so that the edge position of the quantum dot film is easily affected by the external environment (such as moisture or dus...
