Description
본 발명은 광변환 잉크 조성물, 이를 이용하여 제조된 광변환 적층기판 및 광변환 화소기판에 관한 것이다.The present invention relates to a photoconversion ink composition, a photoconversion laminated substrate and a photoconversion pixel substrate manufactured using the same.
정보화 사회가 발전함에 따라 화상을 표시하기 위한 표시장치에 대한 요구가 다양한 형태로 증가하고 있으며, 근래에는 액정표시장치(LCD: Liquid Crystal Display), 플라즈마표시장치(PDP: Plasma Display Panel), 유기전계발광표시장치(OLED: Organic Light Emitting Diode Display Device)와 같은 여러 가지 표시장치가 활용되고 있다.As the information society develops, the demand for display devices for displaying images is increasing in various forms. Recently, liquid crystal displays (LCDs), plasma displays (PDPs), organic electric fields Various display devices such as an organic light emitting diode display device (OLED) are being used.
색 재현율은 표시장치에서 가장 중요한 요소 중 하나이다. 최근에는 표시장치의 색 재현율을 높이기 위한 방안의 일 예로, 통상의 백색 LED를 대체하여 청색 LED를 이용하고, 별도의 광 변환수단인 양자점(quantum dot)을 포함하는 광변환 적층기판을 구비한 표시장치가 사용되고 있다. 예를 들면, 청색의 LED칩을 사용한 백라이트 또는 화소를 포함하는 컬러필터에 양자점이 분산된 광변환층을 포함하는 광변환 적층기판 또는 광변환 화소기판을 적용하여 광변환 효율을 높임으로써 표시장치의 색재현성을 향상하고자 한다.Color gamut is one of the most important factors in a display device. Recently, as an example of a plan to increase the color gamut of a display device, a blue LED is used instead of a normal white LED, and a display having a light conversion laminated board including quantum dots, which are separate light conversion means, is used. Device is in use. For example, by applying a light-conversion multilayer substrate or a light-conversion pixel substrate including a light-conversion layer in which quantum dots are dispersed to a backlight using a blue LED chip or a color filter including pixels to increase the light-conversion efficiency of a display device. It is intended to improve color reproducibility.
한편, 광변환 화소가 적용된 컬러필터를 제조하기 위하여, 양자점과 같은 발광입자를 포함하는 조성물을 이용한 포토리소그래피 방법을 사용할 수 있다. 그러나, 이러한 방법은 컬러 필터의 정교성과 재현성 측면에서는 우수하지만, 화소를 형성하기 위하여 각각의 색에 대하여 코팅, 노광, 현상 및 경화하는 과정이 각각 요구되어 제조 공정, 시간 및 비용이 늘어나고 공정간 제어 인자가 많아져 수율 관리에 어려움이 있다.Meanwhile, in order to manufacture a color filter to which a light conversion pixel is applied, a photolithography method using a composition including light emitting particles such as quantum dots may be used. However, although this method is excellent in terms of sophistication and reproducibility of color filters, processes of coating, exposing, developing, and curing are required for each color to form pixels, which increases the manufacturing process, time and cost, and controls between processes. Yield management is difficult due to the large number of factors.
이러한 문제점들을 해결하기 위하여, 잉크젯(inkjet) 방법이 제시되었다. 잉크젯 방법은 잉크젯 헤드(inkjet head)를 사용하여 구획되어 있는 소정 위치에 액체 잉크를 분사하여 각각의 잉크가 착색된 이미지를 구현하는 기술로, 적색, 녹색 및 청색을 포함한 복수의 색을 한번에 착색할 수 있어서 제조 공정, 시간 및 비용이 크게 절감될 수 있다. In order to solve these problems, an inkjet method has been proposed. The inkjet method is a technology that uses an inkjet head to jet liquid ink to a defined location to create an image in which each ink is colored, and a plurality of colors including red, green, and blue can be colored at once. Thus, the manufacturing process, time and cost can be greatly reduced.

< 광변환 잉크 조성물><Light conversion ink composition>
본 발명의 광변환 잉크 조성물은 발광입자, 중합성 모노머 및 첨가제로써 아민계 아크릴/아크릴아마이드로 나타내는 화합물을 포함하며, 산란입자, 광중합 개시제, 산화방지제 및 용제 중 1종 이상을 더 포함할 수 있다.

발광 입자luminous particles
발광 입자는 예를 들면, 소정의 파장의 광을 흡수함으로써, 흡수한 파장과는 다른 파장의 광을 발할 수 있다. 발광성 나노 결정 입자는, 605 내지 665㎚의 범위에 발광 피크 파장을 갖는 광(적색광)을 발하는 적색 발광 입자일 수 있고, 500 내지 600㎚의 범위에 발광 피크 파장을 갖는 광(녹색광)을 발하는 녹색 발광 입자일 수 있으며, 420 내지 480㎚의 범위에 발광 피크 파장을 갖는 광(청색광)을 발하는 청색 발광 입자일 수 있다. 본 발명의 광변환 잉크 조성물은, 상기 발광 입자 중 적어도 1종을 포함하는 것이 바람직하다.The light-emitting particles can emit light of a wavelength different from the absorbed wavelength by, for example, absorbing light of a predetermined wavelength. The luminescent nanocrystal particles may be red light emitting particles emitting light (red light) having a peak emission wavelength in the range of 605 to 665 nm, and green light emitting light (green light) having a peak emission wavelength in the range of 500 to 600 nm. It may be a light-emitting particle, and may be a blue light-emitting particle that emits light (blue light) having a peak emission wavelength in the range of 420 to 480 nm. The light conversion ink composition of the present invention preferably contains at least one of the light-emitting particles.
본 발명에서, 상기 발광 입자는 반도체 재료를 포함하는 것으로, 예컨대, 양자점 등을 들 수 있다.In the present invention, the light-emitting particles include a semiconductor material, for example, quantum dots and the like.
본 발명의 일 실시예에 있어서, 상기 양자점은 코어 및 상기 코어의 적어도 일부를 덮은 쉘을 포함하는 코어-쉘 구조를 가진다.In one embodiment of the present invention, the quantum dot has a core-shell structure including a core and a shell covering at least a portion of the core.
본 발명에서, 상기 코어-쉘 구조는, 코어와 제1 쉘로 이루어지는 구조, 예컨대 코어/쉘 구조일 수 있고, 코어와 제1 쉘 및 제2 쉘로 이루어지는 구조, 즉 코어/쉘/쉘 구조일 수 있다.In the present invention, the core-shell structure may be a structure composed of a core and a first shell, for example, a core/shell structure, and may be a structure composed of a core, a first shell, and a second shell, that is, a core/shell/shell structure. .
상기 코어는 은(Ag), 인듐(In), 갈륨(Ga) 및 황(S)의 사원소 화합물을 포함한다. 예컨대, 상기 코어는 AgInGaS이다. 이러한 코어는 단파장의 광원을 보다 효율적으로 흡수하고, 발광영역의 광흡수율은 최소화할 수 있는 이점이 있어서, 적은 함량에서도 우수한 광변환 효율을 기대할 수 있다. The core includes a quaternary compound of silver (Ag), indium (In), gallium (Ga), and sulfur (S). For example, the core is AgInGaS. Such a core has an advantage of more efficiently absorbing a short-wavelength light source and minimizing the light absorption rate of the light emitting region, so that excellent light conversion efficiency can be expected even with a small content.
상기 쉘은 In, Ga 및 S 중 적어도 2종의 원소를 포함하며, 예컨대 GaS 등을 포함할 수 있다. 이때, 쉘은 본 발명에서 상기 쉘은 코어의 트랩에미션을 억제하여 발광파장의 반치폭을 좁게 유지할 수 있어서 색순도가 향상되는 기능을 한다.The shell includes at least two elements of In, Ga, and S, and may include, for example, GaS. At this time, in the present invention, the shell functions to improve color purity by suppressing the trap emission of the core and maintaining a narrow half width of the emission wavelength.
예시적인 실시예 따르면, 코어-쉘 구조의 양자점은 AgInGaS/GaS 등을 들 수 있으며, 이에 제한되는 것은 아니다.According to an exemplary embodiment, the quantum dot of the core-shell structure may include AgInGaS/GaS, etc., but is not limited thereto.
일부 실시예에 있어서, 본 발명은 필요에 따라 상술한 코어-쉘 구조 외에 다른 구조의 양자점을 더 포함할 수 있다. 예를 들면, InP/ZnSe/ZnS, InP/ZnS, InGaP/ZnS, InGaP/ZnSe/ZnS 등의 코어-쉘 구조의 양자점을 더 포함할 수 있으나, 이에 제한되는 것은 아니다.In some embodiments, the present invention may further include a quantum dot having a structure other than the core-shell structure described above, if necessary. For example, a core-shell quantum dot such as InP/ZnSe/ZnS, InP/ZnS, InGaP/ZnS, or InGaP/ZnSe/ZnS may be further included, but is not limited thereto.
상기 양자점은 습식 화학 공정(wet chemical process), 유기금속 화학증착 공정(MOCVD, metal organic chemical vapor deposition) 또는 분자선 에피텍시 공정(MBE, molecular beam epitaxy)에 의해 합성될 수 있으나 이에 한정되는 것은 아니나, 바람직하게는 습식 화학 공정(wet chemical process)에 의해 합성하는 것이 더욱 광특성이 우수한 양자점을 수득할 수 있다.The quantum dots may be synthesized by a wet chemical process, a metal organic chemical vapor deposition (MOCVD) process, or a molecular beam epitaxy (MBE) process, but are not limited thereto. , Preferably, it is possible to obtain quantum dots having excellent optical properties when synthesized by a wet chemical process.
상기 습식 화학 공정이란 유기용제에 전구체 물질을 넣어 입자를 성장시키는 방법이다. 결정이 성장될 때 유기용제가 자연스럽게 양자점 결정의 표면에 배위되어 분산제 역할을 하여 결정의 성장을 조절하게 되므로, 유기금속 화학증착 공정이나 분자선 에피텍시와 같은 기상증착법보다 더 쉽고 저렴한 공정을 통하여 나노 입자의 성장을 제어할 수 있으므로, 상기 습식 화학 공정을 사용하여 상기 양자점을 제조하는 것이 바람직하다.The wet chemical process is a method of growing particles by putting a precursor material in an organic solvent. When the crystal grows, the organic solvent is naturally coordinated on the surface of the quantum dot crystal and acts as a dispersant to control the growth of the crystal, so it is easier and cheaper than vapor deposition methods such as organometallic chemical vapor deposition or molecular beam epitaxy to produce nano Since the growth of the particles can be controlled, it is preferred to prepare the quantum dots using the wet chemical process.
본 발명에 있어서, 상기 발광 입자는 상기 광변환 잉크 조성물 중 고형분 총 중량에 대하여 3 내지 50 중량%, 바람직하게는 5 내지 45 중량%, 더욱 바람직하게는 8 내지 40 중량%로 포함될 수 있다. 발광 입자가 상기 범위 내로 포함되는 경우 광변환 효율이 향상될 수 있다.In the present invention, the light-emitting particles may be included in an amount of 3 to 50% by weight, preferably 5 to 45% by weight, and more preferably 8 to 40% by weight, based on the total weight of the solid content in the light conversion ink composition. When the light emitting particles are included within the above range, light conversion efficiency may be improved.
상기 발광 입자가 상기 함량범위 미만으로 포함될 경우 광변환 효율이 저하되어 고품위의 표시장치의 구현이 어려울 수 있다. 또한 상기 함량범위를 초과할 경우 경화를 구현하는 성분들이 부족하여 도막의 경화도 부족에 의해 디스플레이 제조 후공정의 생산성 및 제품의 신뢰성을 저하시킬 수 있다.When the content of the light emitting particles is less than the above range, light conversion efficiency is lowered, making it difficult to implement a high-quality display device. In addition, if the content exceeds the above range, the productivity of the post-production process of the display and the reliability of the product may be reduced due to insufficient curing of the coating film due to lack of components that implement curing.
중합성 모노머polymerizable monomer
본 발명의 일 실시형태에서, 광변환 잉크 조성물은 중합성 모노머를 포함한다.In one embodiment of the present invention, the light conversion ink composition includes a polymerizable monomer.

본 발명에 따른 광변환 잉크 조성물이 산란입자를 포함할 경우, 상기 산란입자를 통해 발광입자에서 방출된 광의 경로를 증가시켜 광변환 코팅층에서의 전체적인 광효율을 높일 수 있어 바람직하다. 이러한 측면에서, 본 발명의 광변환 잉크 조성물은 산란입자로 TiO2, SiO2, ZnO, BaSO4 중에서 선택된 1종 이상을 포함하는 것이 바람직하다.When the light conversion ink composition according to the present invention includes scattering particles, it is preferable to increase the overall light efficiency in the light conversion coating layer by increasing the path of light emitted from the light emitting particles through the scattering particles. In this aspect, the light conversion ink composition of the present invention preferably includes at least one selected from among TiO 2 , SiO 2 , ZnO, and BaSO 4 as scattering particles.
상기 산란입자는 50 내지 1000nm의 평균입경을 가질 수 있으며, 바람직하기로 100 내지 500nm 범위인 것을 사용한다. 이때 입자 크기가 너무 작으면 양자점으로부터 방출된 빛의 충분한 산란 효과를 기대할 수 없고, 이와 반대로 너무 큰 경우에는 조성물 내에 가라 앉거나 균일한 품질의 자발광층 표면을 얻을 수 없으므로, 상기 범위내에서 적절히 조절하여 사용한다.The scattering particles may have an average particle diameter of 50 to 1000 nm, preferably used in the range of 100 to 500 nm. At this time, if the particle size is too small, sufficient scattering effect of the light emitted from the quantum dots cannot be expected, and on the other hand, if it is too large, it sinks in the composition or the surface of the self-luminous layer of uniform quality cannot be obtained. and use it

When the scattering particles are included within the above range, it is preferable that the effect of increasing the luminous intensity can be maximized. If the scattering particles are contained within the above range, it may be difficult to obtain the desired luminous intensity, and if the scattering particles exceed the above range, the transmittance of blue irradiation light is significantly reduced, so that the light conversion of the light emitting particles does not work. It is preferable to use it suitably within the said range.
광중합 개시제photopolymerization initiator
본 발명의 일 실시예에 따른 광변환 잉크 조성물은 광중합 개시제를 추가로 포함할 수 있다.The light conversion ink composition according to an embodiment of the present invention may further include a photopolymerization initiator.
본 발명의 일 실시예에서, 상기 광중합 개시제는 상기 중합성 모노머를 중합시킬 수 있는 것이라면 그 종류를 특별히 제한하지 않고 사용할 수 있다. 예를 들면, 상기 광중합 개시제는 중합특성, 개시효율, 흡수파장, 입수성, 가격 등의 관점에서 아세토페논계 화합물, 벤조페논계 화합물, 트리아진계 화합물, 비이미다졸계 화합물, 옥심계 화합물, 티오크산톤계 화합물 및 포스핀옥사이드 화합물로 이루어지는 군으로부터 선택되는 1종 이상의 화합물을 사용하는 것이 바람직하다.In one embodiment of the present invention, as long as the photopolymerization initiator can polymerize the polymerizable monomer, its kind may be used without particular limitation. For example, the photopolymerization initiator is an acetophenone-based compound, a benzophenone-based compound, a triazine-based compound, a biimidazole-based compound, an oxime-based compound, a tea in terms of polymerization characteristics, initiation efficiency, absorption wavelength, availability, price, etc. It is preferable to use at least one compound selected from the group consisting of oxanthone-based compounds and phosphine oxide compounds.
예를 들면, 5㎛ 이상의 후막경화를 위해서는 옥심계 화합물 또는 포스핀옥사이드 화합물을 사용하는 것이 경화막의 경화밀도 및 표면조도에 더욱 우수한 물성을 확보할 수 있다.For example, for curing a thick film of 5 μm or more, using an oxime-based compound or a phosphine oxide compound can secure better physical properties in terms of cured density and surface roughness of a cured film.
상기 옥심계 화합물의 구체적인 예로는 o-에톡시카르보닐-α-옥시이미노-1-페닐프로판-1-온 등을 들 수 있으며, 시판품으로 바스프사의 Irgacure OXE 01, OXE 02이 대표적이다.Specific examples of the oxime-based compound include o-ethoxycarbonyl-α-oxyimino-1-phenylpropan-1-one, and commercially available products include Irgacure OXE 01 and OXE 02 manufactured by BASF.

상기 광중합 개시제는 상기 광변환 잉크 조성물 중 고형분 총 중량에 대하여 0.1 내지 10 중량%, 바람직하게는 0.5 내지 8 중량%로 포함될 수 있다. 상기 광중합 개시제가 상기 범위 내로 포함되는 경우 상기 광변환 잉크 조성물이 고감도화되어 노광 시간이 단축되므로 생산성이 향상할 수 있기 때문에 바람직하다. 광중합 개시제가 상기 범위 미만으로 포함될 경우 광에 의한 경화가 부족하여 충분한 경도를 얻을 수 없으며, 상기 범위를 초과하여 포함 될 경우 광중합 개시제에 의한 발광입자의 광변환 효율저하가 급격히 증가하여 얻고자 하는 발광세기를 얻을 수 없는 문제가 있으므로, 상기 범위 내에서 사용하는 것이 화소부의 강도와 상기 화소부의 표면에서의 평활성이 양호해지는 이점이 있다.The photopolymerization initiator may be included in an amount of 0.1 to 10% by weight, preferably 0.5 to 8% by weight, based on the total weight of the solid content in the light conversion ink composition. When the photopolymerization initiator is included within the above range, the photoconversion ink composition is highly sensitive and the exposure time is shortened, which is preferable because productivity can be improved. If the photopolymerization initiator is included in an amount less than the above range, sufficient hardness cannot be obtained due to lack of curing by light. If the photopolymerization initiator is included in an amount exceeding the above range, the decrease in light conversion efficiency of the light emitting particles due to the photopolymerization initiator increases rapidly, resulting in the desired emission of light. Since there is a problem of not being able to obtain strength, using it within the above range has the advantage of improving the strength of the pixel portion and the smoothness of the surface of the pixel portion.
상기 광중합 개시제는 본 발명에 따른 광변환 잉크 조성물의 감도를 향상시키기 위해서, 광중합 개시 보조제를 더 포함할 수 있다. 상기 광중합 개시 보조제가 포함되는 경우 감도가 더욱 높아져 생산성이 향상되는 이점이 있다.The photopolymerization initiator may further include a photopolymerization initiator to improve the sensitivity of the light conversion ink composition according to the present invention. When the photopolymerization initiation aid is included, there is an advantage in that the sensitivity is further increased and the productivity is improved.

△ : 2개 이상 ~ 5개 이하의 노즐에서 미토출 발생△: Non-ejection occurs from 2 or more to 5 nozzles
Ｘ : 5개 이상의 노즐에서 미토출 발생X: Non-ejection from 5 or more nozzles
