Abstract

The invention relates to a quantum dot colour film substrate and a display device. The quantum dot colour film substrate comprises a substrate and one or more quantum dot film layer units arranged onthe substrate, wherein each quantum dot film layer unit comprises a nanoporous framework and quantum dots arranged on the nanoporous framework. As the excited quantum dot film layer units can generatelight with different wavelengths to match the colours of different pixel units, the colour effect can be controlled, and meanwhile, the utilization rate of a light source is improved; meanwhile, thequantum dot film layer units comprise the nanoporous frameworks and the quantum dots arranged on the nanoporous framework, so that the nanoporous frameworks can be used for orderly adjusting and controlling the distribution conditions and the sizes of the quantum dots, thus making the quantum dots more uniform, stable and ordered; and therefore, a luminescent spectrum, as well as the distributionand uniformity of the colours are orderly adjusted and controlled; the colour gamut is widened; and the better colour displaying effect is realized.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a quantum dot color film substrate and a display device. Background technique [0002] With the continuous development of display technology, people have higher and higher requirements for display quality and color effects of display devices. Display devices usually utilize color filters to achieve full-color effects. An exemplary color filter is generally composed of a glass substrate, a black matrix, and a color layer. Usually, an LED (Light Emitting Diode, white light emitting diode) backlight source is used to cooperate with the color filter to form a color display. However, this color display mode has a low light source utilization rate, and the display has a narrow color gamut. [0003] Therefore, the exemplary color filter has the problems of low light source utilization and narrow color gamut of the display. Contents of the invention [0004] Based on this, it is ne...
