Problems solved by technology

[0004] Since electronic paper is soft, when the glass substrate filter produced by this method is laminated with electronic paper, there will be problems such as air bubbles and poor bonding
The above-mentioned method of forming a color filter by inkjet printing is not suitable for forming a color filter on a flexible plastic substrate. The curing of the pigment and the formation of the black matrix all require thermal baking. Flexible plastic substrates generally do not have the characteristics of high temperature resistance

Embodiment Construction

[0018] see figure 1 , is a flow chart of the method for manufacturing the color filter with a flexible substrate in a preferred embodiment of the present invention. The method includes steps: Step S301, forming a transparent matrix on a transparent substrate, the transparent matrix divides a plurality of pixel regions on the transparent substrate, and the transparent matrix and the pixel regions have different surface wettability; Step S302, Use the inkjet printing method to apply pigment ink in multiple pixel areas, specifically, inkjet printing is used to position the pigment ink (red pigment ink, green pigment ink, blue pigment ink) on the pixel by using nozzles In the area; step S303, curing the pigment ink to form a plurality of color filter films, wherein specifically exposing the transparent substrate coated with the pigment ink to an ultraviolet light source.

[0019] Please also refer to figure 2 and image 3 , figure 2 It is a subflow chart of step S301 in the ...

Abstract

The invention relates to a manufacture method of a color filter, in particular to a flexible transparent substrate. The manufacture method of the color filter comprises the following steps of: forming a transparent matrix on the transparent substrate to divide the transparent substrate into a plurality of pixel regions, wherein the transparent matrix and the pixel regions have different surface wettabilities, the transparent matrix presents hydrophobicity, and the pixel regions present hydrophilicity; and coating pigment ink in a plurality of pixel regions by utilizing an inkjet printing method and solidifying the pigment ink to form a plurality of color filter films. In the invention, no black matrix needs forming on the substrate, the transparent matrix is directly formed on the transparent substrate to improve the luminousness of the filter, the pigment ink is solidified without a heat roasting program but in a low-temperature thermal solidifying mode or an UV (UltraViolet) solidifying mode to avoid generating adverse influence on a flexible substrate without heat resistance.

Description

technical field [0001] The invention relates to a method for manufacturing a color filter, in particular to a method for manufacturing a color filter with a flexible substrate. Background technique [0002] In recent years, e-books have been favored by more and more readers. E-books use reflective electronic paper displays. Reflective electronic paper has the advantages of no need for backlight, no harm to eyes, and stable display. Existing reflective electronic paper includes electrophoretic electronic paper, cholesteric liquid crystal electronic paper, electrowetting electronic paper, and the like. Electrophoretic electronic paper mostly adopts a microcapsule structure. The microcapsule is wrapped with electrophoretic fluid. Two kinds of electrophoretic particles with opposite charges in black and white are suspended in the electrophoretic fluid. The two electrophoretic particles are under the action of an electric field. Migrate between top and bottom to achieve color sw...
