preparation example Construction

[0067] In another embodiment of the present application, a method for preparing the above-mentioned blue base film is provided, the above-mentioned preparation method includes: coating the above-mentioned blue film composition on the surface of the substrate; and applying the above-mentioned blue film composition Cured into a film.

[0068] The blue base film prepared by the above preparation method plays the same role as the blue glass substrate, and at the same time, it avoids the phenomenon that only the expensive blue glass substrate produced in Japan can be used in the filter, and it is prepared from The thin film is light in weight and small in volume, which is convenient for cutting.

[0069] In yet another embodiment of the present application, a filter is provided, and the filter includes a blue base film, and the blue base film is the above-mentioned blue base film.

[0070] In this filter, the above-mentioned blue base film is used to replace the blue glass produce...

Embodiment 1

[0082] The blue film composition comprises resin main body, blue dyestuff and solvent, and wherein, resin main body is cyclic olefin resin " ZEONOR1420R " (Japanese zeon Co., Ltd. manufacture); Blue dyestuff is cobalt blue, and the weight of cobalt blue is resin main body 2% by weight; the solvent is cyclohexane, and the viscosity of the mixture of the resin body and the solvent is 2500Cps.

[0083] The above-mentioned blue film composition is cured by photo-curing to form a blue film (blue base film), the thickness of the blue film is 200 μm, and the refractive index is 1.45.

Embodiment 2

[0085] The blue film composition includes a resin body, a blue dye, a solvent and nano functional particles, wherein the resin body is a cyclic olefin resin "APEL#6015" (manufactured by Mitsui Chemicals Co., Ltd.); the blue dye is copper phthalocyanine, The weight of copper phthalocyanine accounts for 0.01% of the weight of the resin main body; the solvent is carbon tetrachloride, and the viscosity of the mixture of the resin main body and the solvent is 1Cps. The nano functional particle is Fe-ZnSe particle, the weight of the particle is 1% of the weight of the resin main body, and the average particle diameter of the particle is 10nm.

[0086] The above-mentioned blue film composition is cured by thermal curing to form a blue film, the thickness of the blue film is 2 μm, and the refractive index is 1.8.

Abstract

The invention provides a blue membrane composition, uncured glue, a blue basal membrane, a preparation method for the blue basal membrane, a wave filter and a camera module. The blue membrane composition comprises a resin main body, a blue dye and a solvent, wherein the blue dye has the maximum absorption wavelength of 500nm to 800nm and has intermiscibility with the resin main body; and the resin main body and the blue dye are dispersed in the solvent. The membrane prepared from the blue membrane composition can exert the same action as that of a blue glass substrate; meanwhile, the phenomenon that only expensive blue glass substrates produced by Japan can be adopted in the wave filter is avoided; and the prepared membrane is relatively light in weight, relatively small in size and convenient to cut.

Description

technical field [0001] The invention relates to the technical field of cameras, in particular to a blue film composition, an uncured glue, a blue base film, a preparation method of the blue base film, a filter and a camera module. Background technique [0002] Image sensor CCD (Charge-coupled Device, charge-coupled device) and image sensor CMOS (Complementary Metal-Oxide Semiconductor, metal oxide semiconductor element) in digital imaging technology are photodetectors of a discrete pixel. When the CCD and image sensor CMOS camera captures the target image, the high-frequency harmonics in the image sensor will cause a moiré effect with the fundamental frequency, resulting in Moiré fringes, and the image will produce periodic frequency spectrum overlapping, and even color fringes. In order to eliminate The image interference caused by this spatial high-frequency harmonic, the application of optical filters was born. [0003] Different incident angles of the filter will produc...
