Abstract

The invention provides a display device, comprising a display panel and a backlight module. The backlight module comprises a light source, a fluorescence film and a multi-hole layer. The fluorescence film is arranged on the back side of the display panel and comprises a plurality of quantum dot phosphors. The multi-hole layer is arranged between the fluorescence film and the display panel, covers the fluorescence film, and comprises a plurality of holes. The multi-hole layer is arranged between the fluorescence film and the display panel, or the fluorescence film is internally provided with the multi-hole layer, thereby improving the recycling efficiency of the first light ray generated by the light source, and furthermore increasing the number and brightness of the second light ray generated by the light source, and reducing the manufacturing cost of the backlight module.

Description

technical field [0001] The invention relates to a display device, in particular to a display device which utilizes a porous layer to improve the conversion efficiency of quantum dot fluorescent powder. Background technique [0002] Liquid crystal display devices have been widely used in electronic products such as notebook computers, digital cameras, mobile phones, and LCD TVs. However, since the liquid crystal display devices are not self-illuminating, a backlight module is required for the display function. [0003] With the improvement of the technical level of light-emitting diode components, light-emitting diodes with the advantages of small size, low operating current, low power consumption, long life and low cost have gradually replaced cold cathode fluorescent lamps (CCFL) as the light source of the backlight module. Since a single light-emitting diode can only produce monochromatic light, it is necessary to use red light-emitting diodes, green light-emitting diodes,...
