Description

光轉換樹脂組合物、使用其的光轉換層疊基材及顯示裝置Light conversion resin composition, light conversion laminated substrate using the same, and display device

本發明涉及光轉換樹脂組合物、光轉換層疊基材以及使用該光轉換層疊基材的圖像顯示裝置。The present invention relates to a light conversion resin composition, a light conversion laminated substrate, and an image display device using the light conversion laminated substrate.

在背光單元（Back Light Unit，BLU）中使用發光元件（Light Emitting Diode，LED）的液晶顯示器（Liquid Crystal Display，LCD）電視中，LED背光單元為實際發出光的部分，是在LCD電視中最重要的部分之一。In a Liquid Crystal Display (LCD) TV using a light emitting element (Light Emitting Diode, LED) in a Back Light Unit (BLU), the LED backlight unit is the part that actually emits light, which is the most common in LCD TVs. One of the important parts.

作為形成白色的LED背光單元的方法，通常將紅色（Red，R）、綠色（Green，G）和藍色（Blue，B）的LED晶片組合而形成白色的LED背光單元，或者使用藍色LED晶片與具有寬的半值寬度的發光波長的黃色（Yellow，Y）螢光體的組合而呈現白色。As a method of forming a white LED backlight unit, red (Red, R), green (G, G), and blue (Blue, B) LED chips are usually combined to form a white LED backlight unit, or a blue LED is used. The combination of a wafer and a yellow (Yellow, Y) phosphor with a wide half-value width of the emission wavelength appears white.

然而，在將紅色、綠色、藍色的LED晶片組合的情況下，會有由於LED晶片的個數和複雜的製程而使得製造費用提高的問題，在使黃色螢光體與藍色LED晶片組合的情況下，無法區分綠色和紅色的波長，因此色純度差，存在由此導致的顏色再現性下降的問題。However, when red, green, and blue LED chips are combined, there is a problem that the manufacturing cost increases due to the number of LED chips and a complicated manufacturing process. In the combination of yellow phosphors and blue LED chips, In this case, the wavelengths of green and red cannot be distinguished, so the color purity is poor, and there is a problem that the color reproducibility is reduced due to this.

與此關聯，在專利文獻1中提供了一種光學片，其包含：在高分子樹脂中分散有多個非鎘系量子點，且一面或兩面經圖案化的高分子樹脂層；形成於上述高分子樹脂層的一面的第一阻擋膜；以及形成於上述高分子樹脂層的另一面的第二阻擋膜，上述高分子樹脂層的下部面經棱鏡圖案化或透鏡圖案化，在上述高分子樹脂層的下部面經棱鏡圖案化的情況下，上述棱鏡圖案的間距為20至70μm，頂角為95至120°，上述圖案的截面為三角形；在上述高分子樹脂層的下部面經透鏡圖案化的情況下，上述透鏡圖案的間距為20至70μm，間距與高度的比率為4:1至10:1，上述圖案的截面為半圓形。In connection with this, Patent Document 1 provides an optical sheet including: a polymer resin layer in which a plurality of non-cadmium-based quantum dots are dispersed in a polymer resin, and one or both sides are patterned; A first barrier film on one side of the molecular resin layer; and a second barrier film formed on the other side of the polymer resin layer; a lower surface of the polymer resin layer is prism-patterned or lens-patterned; When the lower surface of the layer is patterned by a prism, the pitch of the prism patterns is 20 to 70 μm, the apex angle is 95 to 120 °, and the cross section of the pattern is triangular. The lower surface of the polymer resin layer is patterned by a lens. In the case of the lens pattern, the pitch of the lens pattern is 20 to 70 μm, the ratio of the pitch to the height is 4: 1 to 10: 1, and the cross section of the pattern is semicircular.

在專利文獻2中提供了一種發光複合體，其包含量子點、以及配置於上述量子點的表面且由特定的化學式表示的胺基矽氧烷系配位基。Patent Literature 2 provides a light-emitting composite including a quantum dot and an aminosilane-based ligand which is arranged on the surface of the quantum dot and is represented by a specific chemical formula.

然而，上述以往技術是除了含有量子點的發光層以外阻擋層、基材層等的結構複雜的光學膜，而且會發生由此導致的量子點的發光亮度下降，從而在製程中以非常高的溫度製作膜時，發生量子點消光的問題。此外，上述以往技術為了加工成光學膜的形態而在低的處理溫度下進行，由此在長期可靠性方面存在問題。However, the above-mentioned conventional technology is an optical film having a complicated structure such as a barrier layer and a substrate layer in addition to a light-emitting layer containing quantum dots, and the light-emitting brightness of the quantum dots caused by this will decrease, which will cause a very high When a film is made at a temperature, the problem of extinction of quantum dots occurs. In addition, the above-mentioned conventional technology is performed at a low processing temperature in order to be processed into the form of an optical film, and thus has a problem in long-term reliability.
