Abstract

The embodiment of the invention provides a quantum dot color film substrate, a display panel and a display device, related to the technical field of display and used for compensating difference of conversion efficiency of quantum dots of different colors to blue light and improving a color cast phenomenon caused by the difference of conversion efficiency of the quantum dots of different colors tothe blue light. The quantum dot color film substrate is used for being used in cooperation with a blue backlight source. The quantum dot color film substrate comprises a plurality of pixel units arranged in arrays; the pixel unit comprises a blue subpixel, a red subpixel and a green subpixel, wherein the red subpixel comprises a red quantum dot color film, and the green subpixel comprises a greenquantum dot color film; area ratio of the blue subpixel, the red subpixel and the green subpixel is 1:X:Y, wherein X is greater than or equal to 2.5 and less than or equal to 5, and Y is greater thanor equal to 4 and less than or equal to 6.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of display technology, in particular to a quantum dot color film substrate, a display panel and a display device. [0003] 【Background technique】 [0004] Quantum Dots, also known as nanocrystals, are nanoparticles composed of II-VI or III-V elements. The particle size of quantum dots is generally between a few nanometers and tens of nanometers. Due to the existence of the quantum confinement effect, the original continuous energy band structure of the quantum dot material becomes a discrete energy level structure, which can emit visible light after being excited. Moreover, quantum dot materials have the advantages of concentrated luminescence spectrum, high color purity, and continuously adjustable luminescence spectrum. Using these advantages to apply quantum dot materials to display devices can effectively improve the color gamut and color reproduction capability of display devices. [0005] A display pan...
