Abstract

The present specification relates to a nitrogen-containing compound, a color conversion film comprising the same, and a backlight unit and a display device each comprising same.

Description

Nitrogen compound, color conversion film containing the same, and backlight unit and display device including the same

TECHNICAL FIELD The present invention relates to a nitrogen-containing compound, a color conversion film comprising the same, a backlight unit, and a display device.

This specification is based on Korean Patent Application No. 10-2017-0167119 filed on December 7, 2017, and Korean Patent Application No. 10-2018-0156173 filed on December 6, 2018 All of which are incorporated herein by reference.

Conventional light emitting diodes (LEDs) are obtained by mixing a green phosphor and a red phosphor in a blue light emitting diode or by mixing a yellow phosphor and a blue-green phosphor in a UV light emitting diode. However, such a method is difficult to control the color and thus has poor color rendering properties. Therefore, the color reproduction rate drops.

Recently, attempts have been made to realize green and red colors by bonding quantum dots to a blue LED in order to overcome the decrease in the color reproducibility and reduce the production cost. However, cadmium-based quantum dots have safety problems, and other quantum dots are less efficient than cadmium-based ones. Further, the quantum dots have a disadvantage that their stability against oxygen and water is poor and their performance remarkably decreases when they are aggregated. Moreover, it is difficult to keep the size of the quantum dot constant during the production of the quantum dot, resulting in a high production cost.

The present specification provides a nitrogen-containing compound, a color conversion film containing the same, a backlight unit, and a display device.

The content of the compound represented by the formula (1) in the color conversion film may be in the range of 0.001 to 10% by weight.

The color conversion film may contain one kind or two or more kinds of the compounds represented by the above formula (1).

The color conversion film may further include a fluorescent substance in addition to the compound represented by Formula 1. [ When a light source that emits blue light is used, the color conversion film preferably includes both a green light emitting fluorescent material and a red light emitting fluorescent material. When a light source that emits blue light and green light is used, the color conversion film may include only a red light emitting fluorescent material. However, the present invention is not limited thereto. In the case of using a light source that emits blue light, when a separate film containing a green light emitting fluorescent material is laminated, the color conversion film may include only a red light emitting compound. Conversely, even when a light source that emits blue light is used, in the case of laminating a separate film containing a red light-emitting fluorescent material, the color conversion film may include only a green light-emitting compound.

Wherein the color conversion film comprises a resin matrix; And a further layer containing a light-emitting compound dispersed in the resin matrix and having a wavelength different from that of the compound represented by the general formula (1). The compound emitting light having a wavelength different from that of the compound represented by the formula (1) may also be a compound represented by the formula (1) or a known fluorescent material.

The material of the resin matrix is preferably a thermoplastic polymer or a thermosetting polymer. Specifically, examples of the material of the resin matrix include poly (meth) acrylate, polycarbonate (PC), polystyrene (PS), polyarylene (PAR), polyurethane (TPU ), Styrene-acrylonitrile series (SAN), polyvinylidene fluoride series (PVDF), and modified polyvinylidene fluoride series (modified-PVDF).

According to one embodiment of the present specification, the color conversion film according to the above-described embodiment further includes light diffusing particles. By dispersing the light diffusion particles in the color conversion film in place of the conventional light diffusion film in order to improve the brightness, the adhesion process can be omitted as compared with the use of a separate optical acid film, .

As the light-diffusing particles, resin matrices and particles having a high refractive index can be used. For example, TiO ₂ , silica, borosilicate, alumina, sapphire, air or other gas, air- or gas- filled hollow beads or particles , Air / gas-filled glass or polymer); Polymer particles including polystyrene, polycarbonate, polymethylmethacrylate, acrylic, methylmethacrylate, styrene, melamine resin, formaldehyde resin, or melamine and formaldehyde resin, or any suitable combination thereof may be used .

The particle size of the light-diffusing particles may be in the range of 0.1 micrometer to 5 micrometers, for example, in the range of 0.3 micrometer to 1 micrometer. The content of the light-diffusing particles may be determined as necessary, and may be, for example, within a range of about 1 to 30 parts by weight based on 100 parts by weight of the resin matrix.

The color conversion film according to the above-described embodiment may have a thickness of 2 micrometers to 200 micrometers. In particular, the color conversion film can exhibit high luminance even at a thin thickness of 2 to 20 micrometers. This is because the content of the fluorescent substance molecules contained in the unit volume is higher than the quantum dots.

The color conversion film according to the above-described embodiments may have a substrate on one side thereof. This substrate may serve as a support in the production of the color conversion film. The kind of the substrate is not particularly limited and is not limited to the material and thickness as long as it is transparent and can function as the support. Here, transparent means that the visible light transmittance is 70% or more. For example, a PET film may be used as the substrate.

The above-mentioned color conversion film can be produced by coating a resin solution in which the compound represented by the formula (1) has been dissolved on a substrate and drying or extruding the compound represented by the formula (1) together with the resin to form a film.

Since the compound represented by the above-mentioned formula (1) is dissolved in the resin solution, the compound represented by the formula (1) is homogeneously distributed in the solution. This is different from the manufacturing process of a quantum dot film requiring a separate dispersion process.

The resin solution in which the compound represented by Formula 1 is dissolved is not particularly limited as long as the compound represented by Formula 1 is dissolved in the solution.

According to an example, the resin solution in which the compound represented by Formula 1 is dissolved may be prepared by preparing a first solution by dissolving the compound represented by Formula 1 in a solvent, dissolving the resin in a solvent to prepare a second solution, And then mixing the solution and the second solution. When the first solution and the second solution are mixed, it is preferable to mix them homogeneously. However, the present invention is not limited to this, and a method of dissolving the compound represented by Chemical Formula 1 and a resin simultaneously in a solvent to dissolve the compound represented by Chemical Formula 1 and dissolving the compound represented by Chemical Formula 1 in a solvent followed by dissolving the resin by dissolving the resin in a solvent, A method of dissolving a compound represented by the formula

As the resin contained in the solution, the above-mentioned resin matrix material, a monomer curable with the resin matrix resin, or a mixture thereof can be used. For example, as the monomer curable with the resin matrix resin, there is a (meth) acrylic monomer, which can be formed from a resin matrix material by UV curing. In the case of using such a curable monomer, an initiator necessary for curing may be further added if necessary.

The solvent is not particularly limited and is not particularly limited as long as it can be removed by drying without adversely affecting the coating process. Nonlimiting examples of the solvent include toluene, xylene, acetone, chloroform, various alcohol solvents, MEK (methyl ethyl ketone), MIBK (methyl isobutyl ketone), EA (ethyl acetate), butyl acetate, DMF Dimethylformamide), DMAc (dimethylacetamide), DMSO (dimethylsulfoxide), NMP (N-methyl-pyrrolidone) and the like may be used alone or in admixture of two or more. When the first solution and the second solution are used, the solvent contained in each of these solutions may be the same or different. Even when different kinds of solvents are used for the first solution and the second solution, it is preferable that these solvents have compatibility so that they can be mixed with each other.

A roll-to-roll process can be used for the step of coating the resin solution on which the compound represented by the formula (1) is dissolved. For example, a step of dissolving a substrate from a roll on which a substrate is wound, coating a resin solution in which the compound represented by the formula (1) is dissolved on one surface of the substrate, drying, and then winding the same on a roll again. In the case of using a roll-to-roll process, it is preferable to determine the viscosity of the resin solution within a range in which the process can be performed, and may be determined within a range of, for example, 200 to 2,000 cps.

As the coating method, various known methods can be used, for example, a die coater may be used, and various bar coating methods such as a comma coater, a reverse comma coater, and the like may be used.

After the coating, a drying process is performed. The drying process can be carried out under the conditions necessary for removing the solvent. For example, the substrate is dried in an oven located adjacent to the coater in a direction in which the substrate proceeds in a coating process, under conditions that the solvent is sufficiently blown, and a color conversion including a fluorescent substance, A film can be obtained.

When a monomer curable with the resin matrix resin is used as the resin contained in the solution, curing such as UV curing may be performed before or during the drying.

When the compound represented by the formula (1) is extruded together with the resin to form a film, extrusion methods known in the art can be used. For example, the compound represented by the formula (1) is reacted with a polycarbonate- ) Acrylic resin, and styrene-acrylonitrile (SAN) resin are simultaneously extruded to produce a color conversion film.
