Abstract

The invention provides a display device which comprises a display panel and a backlight source, wherein the display panel comprises an upper base plate and a lower base plate which are oppositely arranged; a reflecting type light filtering layer and a colorful illuminating layer are overlapped on the upper base plate in turn from top to bottom; the colorful illuminating layer comprises a red quantum dot area, a green quantum dot area and a blue quantum dot area; the backlight source is located under the lower base plate, so that the colorful illuminating layer can respectively emit red, green and blue light and the light can penetrate through the reflecting type light filtering layer; and the reflecting type light filtering layer can locally reflect the light emitted from the backlight source to the reflecting type light filtering layer onto the colorful illuminating layer and then the colorful illuminating layer is excited to illuminate again, so that the lighting effect is promoted. The display device is capable of increasing the use ratio of light energy of the backlight source and the illuminating efficiency of the colorful illuminating layer, so that the content of quantum dot in the colorful illuminating layer can be reduced under the condition of less influence and even no influence on the illuminating effect and the content of cadmium element in the quantum dot can be further reduced so as to meet the standard requirement.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device. Background technique [0002] Due to the advantages of adjustable luminous spectrum and high luminous efficiency, quantum dots are used in displays to improve the display color gamut of displays. For quantum dots, they can be divided into quantum dots containing cadmium materials and quantum dots without cadmium. Quantum dots containing cadmium have higher luminous efficiency and narrower emission spectrum than quantum dots without cadmium, so the effect of quantum dots containing cadmium is better when applied to displays. [0003] However, since cadmium is an element that is clearly required to limit the concentration in the "Directive on the Restriction of the Use of Certain Hazardous Components in Electrical and Electronic Equipment" (ROHS) standards, when selecting cadmium-containing quantum dots for use in displays, it is necessary to use them in ...
