Packaging quantum dot material display panel and backlight module comprising panel

Abstract

The invention discloses a packaging quantum dot material display panel. The packaging quantum dot material display panel comprises a color conversion layer, a dichroic optical material layer and a liquid crystal material packaging layer, wherein the color conversion layer is excited by outgoing light to generate excited light; the dichroic optical material layer is fitted to the lower side of the color conversion layer and is provided with a film plating region; the film plating region has high permeability on a waveband of an appointed color which is appointed in advance, and high reflection characteristics on wavebands of other colors except the appointed color; the film plating region can be used for reflecting the excited light scattered toward the direction of the dichroic optical material layer to the direction of the color conversion layer, so that the loss of light energy is reduced and the light emitting efficiency is remarkably improved. Meanwhile, the invention further discloses a backlight module comprising the panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel packaged with quantum dot materials. The invention also relates to a backlight module. Background technique [0002] Liquid crystal display is a flat and ultra-thin display device, which consists of a certain number of color or black and white pixels, placed in front of the light source or reflective surface. Liquid crystal displays consume very little power, making them favored by engineers for electronic devices that run on batteries. Its main principle is to stimulate liquid crystal molecules with current to generate points, lines, and surfaces to form a picture with the back lamp tube. [0003] As the name suggests, LCD monitors work through liquid crystals. Liquid crystal is a special substance between solid and liquid. It is an organic compound, which is liquid under normal conditions, but its molecular arrangement is as regular as that of solid crystals...

Problems solved by technology

The working diagram of the color conversion layer composed of these fluorescent particles is shown in Figure 4 As shown, when the blue light reaches the color conversion layer of the sub-pixel of the panel, the light generated by the quantum dots excited by the blue light has a backward light, and this part cannot be used, resulting in a decrease in light extraction efficiency
