Display panel and display device

Abstract

The invention discloses a display panel and a display device. The display panel comprises an upper substrate, a lower substrate, a liquid crystal layer, a quantum dot color film layer and electrode structures. The upper substrate and the lower substrate are opposite to each other, the liquid crystal layer is positioned between the upper substrate and the lower substrate, the quantum dot color film layer which comprises a plurality of sub-pixels is positioned between the upper substrate and the liquid crystal layer, and the electrode structures are positioned between the upper substrate and the lower substrate; the sub-pixels are divided into annular quantum dot color film regions and shading regions, and the shading regions are positioned on the centers and the peripheries of the annular quantum dot color film regions. The display panel and the display device have the advantages that positional relations between focal points of lenses and the central shading regions of the sub-pixels are controlled, backlight of the liquid crystal layer is absorbed by the central shading regions or the peripheral shading regions of the sub-pixels to different degrees under the control, and accordingly the brightness of the sub-pixels can be adjusted; phase samples of the various sub-pixels are controlled, accordingly, pictures can be displayed, and the display color gamut can be enhanced.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] Quantum Dot (Quantum Dot) is usually a nanoparticle composed of II-VI or III-V elements, which can emit fluorescence after being excited. The luminescence spectrum can be controlled by changing the size of the quantum dot, and its fluorescence intensity And stability are very good, is a kind of very good photoluminescent material. There are many kinds of quantum dots, representative ones are CdS / CdSe / CdTe / ZnO / ZnS / ZnSe / ZnTe of II-VI groups and III-V groups GaAs, GaP, GaAs, GaSb, HgS, HgSe, HgTe, InAs, InP, InSb, AlAs, AlP, AlSb, etc. Among them, the quantum dots of the same substance emit different light according to the size of their preparation. Quantum dot luminescent materials have the characteristics of adjustable luminescent wavelength, high luminous color purity, and high-efficiency luminescence...
