Abstract

The invention provides a quantum dot diaphragm and a backlight module. The quantum dot quantum comprises a first barrier film layer, a second barrier film layer, wherein the second barrier film layeris disposed opposite to the first barrier film layer, a light emitting layer, wherein the light emitting layer is disposed between the second barrier film layer and the first barrier film layer. The material of the light emitting layer comprises green fluorescent powder, red quantum dots and dispersion medium, wherein the green fluorescent powder comprises gamma-AlON: Mn2+, Mg2+green fluorescent powder. The backlight module comprises the quantum dot diaphragm, a light transmission plate, wherein the light transmission plate comprises a light incident surface and a light emitting surface, at least one light source, wherein the light source is arranged opposite to the light incident surface of the transmission plate. The quantum dot diaphragm is attached to the light emitting surface of thelight transmission plate. The quantum dot diaphragm and the backlight module has the technical effects that the novel quantum dot diaphragm is formed by utilizing the special structure of the quantumdot diaphragm and the material of the light emitting layer, so that the use of the green quantum dot material is reduced, the high color gamut is realized, the water and oxygen are highly blocked, theproduction cost is reduced, and the green and environmental protection is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot film and a backlight module. Background technique [0002] Most of the current liquid crystal displays are backlight liquid crystal display devices, and white LEDs (Light Emitting Diode) are generally used as the backlight source. The most common white LED is a blue light-emitting chip plus a yellow yttrium aluminum garnet (YAG) phosphor LED. The LED using the yellow phosphor material is matched with an LCD screen. The color saturation is low, and its display area is generally 72% NTSC. (National Television System Committee), the display colors are not vibrant enough. In order to improve color saturation, the yellow phosphor can be changed to red-green (RG) phosphor, but this method can increase the color gamut by about 25% at most, and cannot meet the new BT.2020 color gamut standard (equivalent to 134% NTSC ). [0003] In order to achieve 80% of the BT.2020 co...
