Abstract

The invention discloses a manufacturing method of a quantum dot color filter and a display panel. The manufacturing method of the quantum dot color filter comprises the following steps: manufacturing a first substrate, wherein the first substrate comprises a first substrate, and a surface treatment film and a quantum dot film which are sequentially arranged on the first substrate; manufacturing a second substrate, wherein the second substrate comprises a second substrate and a color resistance layer arranged on the second substrate; arranging the first substrate and the second substrate oppositely, and enabling the quantum dot film to be in contact with the color resistance layer; and stripping the second substrate from the first substrate, and enabling the quantum dot film in contact with the color resistance layer to be transferred to the color resistance layer, wherein the stripping force between the quantum dot film and the color resistance layer is greater than the stripping force between the quantum dot film and the surface treatment film. The quantum dot color filter with high energy efficiency, high resolution and high contrast can be obtained, and mass production of the display panel containing the quantum dot color filter can be realized.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for manufacturing a quantum dot color filter and a display panel. Background technique [0002] Quantum dot color filter (Quantum Dot Color Filter, QDCF) has the technical characteristics of high color gamut and wide viewing angle, with Mini LED (Light-Emitting Diode, light-emitting diode), Micro LED, OLED (Organic Light-Emitting Diode, organic light-emitting Diode) backlight technology can show excellent picture quality and is the most competitive product in the future display technology. [0003] At present, the display technology using QDCF has no mass products, and one of the main reasons is that the existing QDCF manufacturing process has defects. For example, the use of QD PR (Quantum Dot Photoresist, quantum dot photoresist) lithography technology to produce QDCF will be affected by the decrease in light efficiency and poor reliability of QD materials;...
