Abstract

The embodiment of the invention provides a preparation method of a flexible substrate, which comprises the following steps of: providing a hard substrate, and forming a thin film layer on the surfaceof the hard substrate; treating the surface of the thin film layer, so that a hydrophilic region and a hydrophobic region are formed on the surface of the thin film layer, wherein the hydrophilic region or the hydrophobic region comprises a preset black matrix pattern; coating a mixed solution comprising hydrophilic organic polymer and hydrophobic organic polymer on the whole surface of the thin film layer, and forming a flexible substrate layer comprising a transparent region and a black matrix region on the surface of the thin film layer after being subjected to constant temperature treatment and baking treatment; stripping the thin film layer and the hard substrate to obtain the flexible substrate. The preparation method is simple in process, saves the preparation of a prior black matrix, and greatly shortens the process time and the process cost. The invention also provides a flexible substrate, a color film substrate and a display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a flexible substrate and a preparation method thereof, a color filter substrate, and a display panel. Background technique [0002] With the development of flat panel display technology, the performance requirements of the display panel are getting higher and higher. Display panels with the advantages of high resolution, flexibility, thinness, high brightness, high contrast, low power consumption, and high color gamut have become the main direction of development. In particular, flexible displays are favored by consumers due to their features such as large viewing angles, rollability, and portability, and have become a research hotspot in the industry for portable products. However, due to the limitations of the existing technology, it is difficult to manufacture a flexible, high color gamut, and low power display panel, such as a commonly used liquid crystal display device (Li...
