Example Embodiment
[0041] Example 1
[0042] This embodiment provides a high-resolution fluorescent display screen and a preparation method thereof.
[0043] A high-resolution fluorescent display:
[0044] Such as figure 1 As shown, the high-resolution fluorescent display in this embodiment consists of a substrate (1), a red fluorescent material layer (2), a first isolation layer (3), a green fluorescent material layer (4), and a second isolation layer (5). , The blue fluorescent material layer (6) and the protective layer (7) are laminated in sequence.
[0045] The substrate is made of glass;
[0046] The structural formula of the material of the red fluorescent material layer is as follows:
[0047]
[0048] The structural formula of the material of the green fluorescent material layer is as follows:
[0049]
[0050] The structural formula of the material of the blue fluorescent material layer is as follows:
[0051]
[0052] Where R is C 8 H 17 ;
[0053] The material of the first isolation layer and the...
Example Embodiment
[0059] Example 2
[0060] This embodiment provides a high-resolution fluorescent display screen and a preparation method thereof.
[0061] The structure of the high-resolution fluorescent display screen in this embodiment and the preparation method thereof are the same as those in Embodiment 1, except that the materials of the fluorescent material layer and the isolation layer, and the curing process of each layer are different.
[0062] Among them, the material of the fluorescent material layer is a small molecule fluorescent material, which is specifically as follows:
[0063] The red fluorescent material uses rhodamine series alcohol-soluble dyes, and the red fluorescent material is dispersed in an acrylic alcohol solution that can be thermally crosslinked during spin coating. After spin coating, cure at 120°C for 10 minutes.
[0064] The green fluorescent material adopts coumarin dye, and when spin coating, the green fluorescent material is dispersed in the polyurethane prepolymer ...
Example Embodiment
[0067] Example 3
[0068] This embodiment provides a high-resolution fluorescent display screen and a preparation method thereof.
[0069] The structure and composition of the high-resolution fluorescent display screen in this embodiment are the same as those in Embodiment 1, except that each layer is prepared by the method of pulling and forming a film.
