Description
本發明是有關於一種光學膜及含有該光學膜的發光裝置與顯示器，特別是指一種能提升色域的光學膜及含有該光學膜且具有廣色域的發光裝置與顯示器。The present invention relates to an optical film and a light-emitting device and display including the same, and more particularly to an optical film capable of improving color gamut and a light-emitting device and display having the wide color gamut including the optical film.
現有的發光二極體( l i g h t emi t t i n g d i o d e ，LED)發光裝置產生白光的其中一種方式係利用量子點( q u a n t um d o t s )作為發光二極體的發光層，藉由不同材料或粒徑的量子點受到激發光源照射，發出不同於激發光源之波長的二次光線後混光而得。舉例來說，大多是以藍光作為激發光源，並激發不同粒徑的量子點材料以產生紅光及綠光，而後便可將紅光、綠光，及藍光以混光的方式形成白光。One of the ways in which the existing light emi tting diode (LED) illuminating device produces white light is to use quantum dots (quant um dots) as the luminescent layer of the light-emitting diode, and the quantum dots of different materials or particle diameters are received. The excitation light source is irradiated, and a secondary light having a wavelength different from that of the excitation light source is emitted and mixed. For example, most of the blue light is used as an excitation light source, and quantum dot materials of different particle sizes are excited to generate red light and green light, and then red light, green light, and blue light can be mixed to form white light.
然而，現有的以藍光或紫外光激發產生白光的發光方式，其存在的缺點在於，各色光的光頻譜呈現連續分佈，因而會使得整體的色純度降低，當將該發光二極體發光裝置應用於一顯示器作為背光源時，便會造成該顯示器的色彩表現範圍(色域)降低，部分實際的色彩無法呈現。又，色域(color gamut)即是該顯示器所能表達的顏色數量所構成的範圍區域，也就是其所能表現的顏色範圍，而此顏色範圍是由紅(R)、綠(G)、藍(B)三種純色的座標所圍成的三角形面積，三角形的面積越大代表色域範圍越廣，色域越廣的顯示器其色彩的表現就越豐富也更為真實。However, the existing light-emitting method of generating white light by blue light or ultraviolet light has the disadvantage that the light spectrum of each color light is continuously distributed, thereby reducing the overall color purity, when the light-emitting diode light-emitting device is applied. When a display is used as a backlight, the color performance range (color gamut) of the display is lowered, and some actual colors cannot be presented. Moreover, the color gamut is the range of the number of colors that the display can express, that is, the range of colors that it can represent, and the color range is from red (R), green (G), Blue (B) The area of the triangle enclosed by three solid color coordinates. The larger the area of the triangle, the wider the color gamut, and the wider the color gamut, the richer and more realistic the color.
換言之，影響該顯示器色域呈現能力的主要因素之一即在於背光源的選擇，高色域的背光源，該顯示器所呈現的顏色會更為豐富，可更接近物體本身的顏色且色彩鮮明，低色域的背光源，則會使該顯示器所呈現的顏色產生偏差，而無法完全表現出物體實際的顏色。也就是說，顯示器色域的優劣，會直接影響人眼對物體顏色的判斷能力，因此，以使用者的角度而言，廣色域的顯示器一直以來都具有高度的市場需求。In other words, one of the main factors affecting the color gamut rendering capability of the display is the choice of the backlight, the backlight of the high color gamut, the color of the display will be more abundant, and the color of the object itself can be closer to the color. A low color gamut backlight will cause the display to be biased in color and will not fully represent the actual color of the object. That is to say, the advantages and disadvantages of the color gamut of the display will directly affect the ability of the human eye to judge the color of the object. Therefore, from the perspective of the user, the display of the wide color gamut has always had a high market demand.
基於上述原因，進一步開發或設計一種能提升色域的光學膜，並將其應用於發光裝置與顯示器，使該顯示器具有優異的色彩表現，以滿足市場需求，進而提升經濟價值，係為本發明研究改良的重要目標。For the above reasons, further develop or design an optical film capable of improving color gamut, and apply it to a light-emitting device and a display, so that the display has excellent color performance to meet market demand, thereby enhancing economic value, and is based on the present invention.

The technical contents, features and effects of the present invention will be apparent from the following detailed description.
參閱圖1，本發明發光裝置1的一第一實施例包含一光學膜2，及一發光模組3。本發明該第一實施例主要是藉由該光學膜2的設置而達到廣色域的目的。Referring to FIG. 1, a first embodiment of a light-emitting device 1 of the present invention comprises an optical film 2 and a light-emitting module 3. The first embodiment of the present invention mainly achieves the purpose of wide color gamut by the arrangement of the optical film 2.
該光學膜2包括一第一基材21、一與該第一基材21間隔相對的第二基材22，及一位於該第一、二基材21、22之間的散射層23。The optical film 2 includes a first substrate 21, a second substrate 22 spaced apart from the first substrate 21, and a scattering layer 23 between the first and second substrates 21, 22.
該第一基材21具有相反的一第一面211與一入光面212，該第二基材22具有一朝向該第一面211的第二面221、一相反於該第二面221的出光面222。其中，該第一基材21與第二基材22由高分子材料所構成，且構成材料可為相同或不同，較佳地，該第一、二基材21、22的構成材料可選自聚對苯二甲酸乙二酯(polyethylene terephthalate，PET)、環狀烯烴共聚高分子(cyclo olefin (co)-polymers，COC)、聚亞醯胺(polyimide，PI)、聚醚碸樹脂(polyestersulfone，PES)、聚萘二甲酸乙二醇酯(polyethylene naphthalate，PEN)、聚碳酸酯(polycarbonate，PC)，或前述其中之一組合。The first substrate 21 has an opposite first surface 211 and a light incident surface 212. The second substrate 22 has a second surface 221 facing the first surface 211 and a second surface 221 opposite thereto. Light exit surface 222. The first substrate 21 and the second substrate 22 are made of a polymer material, and the constituent materials may be the same or different. Preferably, the constituent materials of the first and second substrates 21 and 22 may be selected from the following materials. Polyethylene terephthalate (PET), cycloolefin (co)-polymers (COC), polyimide (PI), polyether sulfonate (polyestersulfone) PES), polyethylene naphthalate (PEN), polycarbonate (PC), or a combination of the foregoing.
該散射層23位於該第一面211與該第二面221之間，並含有多數量子點231與多數散射粒子232，該等量子點231於接受一第一色光激發後，可發出一波長大於該第一色光之波長的第二色光。The scattering layer 23 is located between the first surface 211 and the second surface 221 and includes a plurality of quantum dots 231 and a plurality of scattering particles 232. The quantum dots 231 emit a wavelength after being excited by a first color light. a second color light that is greater than the wavelength of the first color light.
詳細的說，該等量子點231是一種奈米晶體半導體材料，主要是由II-VI或III-V族化合物所合成之半導體量子點，可於受到激發光的照射後，發出不同於激發光的二次光線，且該等量子點231可藉由材料的選擇或粒徑大小的調整，改變受到激發光照射後的發光波長，從而發出與激發光不同顏色的色光。該等散射粒子232大致均勻地分散於該散射層23中，藉由該等散射粒子232可讓進入該散射層23的該第一色光於接觸該等散射粒子232時產生多次的反射與散射，而增加該第一色光於該散射層23的光路徑，以提升光子碰撞該等量子點231的機率，進而增加該等量子點231受激發後所發出的二次光線的強度。In detail, the quantum dots 231 are nanocrystalline semiconductor materials, mainly semiconductor quantum dots synthesized by II-VI or III-V compounds, which can emit different excitation light after being irradiated by the excitation light. The secondary light rays, and the quantum dots 231 can change the light-emitting wavelength after being irradiated by the excitation light by the selection of the material or the adjustment of the particle size, thereby emitting color light of a different color from the excitation light. The scattering particles 232 are substantially uniformly dispersed in the scattering layer 23, and the scattering particles 232 allow the first color light entering the scattering layer 23 to generate multiple reflections when contacting the scattering particles 232. Scattering increases the light path of the first color light to the scattering layer 23 to increase the probability of photons colliding with the quantum dots 231, thereby increasing the intensity of the secondary rays emitted by the quantum dots 231 after being excited.
本實施例係利用該等量子點231的粒徑控制，以令該第一色光激發該等量子點231而發出波長大於該第一色光之波長的第二色光及第三色光，其中，該第一色光為藍光，該第二色光與該第三色光的其中之一為紅光，另一為綠光，便可使其經由混光後而向外發出白光。特別的是，本發明還進一步藉由該等散射粒子232增加該第一色光(藍光)於該散射層23的光路徑，以提升該第一色光與該等量子點231的碰撞機率，而增加該第二、三色光(紅、綠光)的強度，因此，可有效地提升該第二色光及第三色光的轉換效率，進而擴大紅、綠、藍三種純色的座標所圍成的三角形面積，達到廣色域的目的。In this embodiment, the particle size control of the quantum dots 231 is used to cause the first color light to excite the quantum dots 231 to emit second color light and third color light having a wavelength greater than the wavelength of the first color light. The first color light is blue light, and one of the second color light and the third color light is red light, and the other is green light, so that it can emit white light outward after being mixed. In particular, the present invention further increases the light path of the first color light (blue light) to the scattering layer 23 by the scattering particles 232 to enhance the collision probability of the first color light with the quantum dots 231. The intensity of the second and third color lights (red, green light) is increased, so that the conversion efficiency of the second color light and the third color light can be effectively improved, thereby expanding the coordinates of the three solid colors of red, green and blue. The area of the triangle reaches the goal of wide color gamut.
於本實施例中，該等量子點231的粒徑介於1 nm至50 nm，且較佳地，該等量子點231的粒徑是介於2 nm至15 nm。該等散射粒子232的粒徑介於1 nm至10 mm，且構成材料可選自二氧化矽(SiO2 )、二氧化鈦(TiO2 )、二氧化鍺(GeO2 )、二氧化鋯(ZrO2 )、三氧化二鋁(Al2 O3 )，或前述其中之一組合。In this embodiment, the quantum dots 231 have a particle diameter of 1 nm to 50 nm, and preferably, the quantum dots 231 have a particle diameter of 2 nm to 15 nm. The scattering particles 232 have a particle diameter of 1 nm to 10 mm, and the constituent material may be selected from the group consisting of SiO 2 , TiO 2 , GeO 2 , and ZrO 2 . ), aluminum oxide (Al 2 O 3 ), or a combination of the foregoing.
此處要說明的是，前述散射粒子232係透過與四周材料的折射率差異而產生一次性的散射特性，如添加的量過高，則會產生光線透過率驟降的問題。因此，可採用凝膠微包法的方式，即於該每一散射粒子232的表面包覆至少一層凝膠層(圖未示)，便能透過該凝膠層的包覆產生漸變式的折射率變化，較佳地，該凝膠層的構成材料可選自聚甲基丙烯酸甲酯(polymethylmethacrylate，PMMA)、矽氧樹脂(silicone)、氨基鉀酸酯(urethane)、聚氨酯橡膠(poly urethane)、聚丙烯(polypropylene，PP)，或前述其中之一組合。由於該等散射粒子232透過該凝膠層產生漸變式的折射率變化，從而可提高光線有效偏折的效率並增加光等效行進的路徑，以提升光轉換效率，並降低激發光因一次性散射粒子所產生出光效率偏低的特性。Here, the scattering particles 232 are transmitted through a difference in refractive index from the surrounding materials to produce a one-time scattering characteristic. If the amount of addition is too high, there is a problem that the light transmittance is suddenly lowered. Therefore, a gel micro-packaging method may be adopted in which at least one gel layer (not shown) is coated on the surface of each of the scattering particles 232 to form a gradual refraction through the coating of the gel layer. Preferably, the constituent material of the gel layer may be selected from the group consisting of polymethylmethacrylate (PMMA), silicone, urethane, and polyurethane. Polypropylene (PP), or a combination of the foregoing. Since the scattering particles 232 pass through the gel layer to produce a gradual refractive index change, the efficiency of effective deflection of the light can be increased and the path of optical equivalent travel can be increased to improve the light conversion efficiency and reduce the excitation light. The scattering particles produce a characteristic that the light efficiency is low.
此外，還要說明的是，該等散射粒子232與包覆有該凝膠層的該等散射粒子232除了可分別單獨使用之外，亦可二者同時搭配使用。In addition, it is to be noted that the scattering particles 232 and the scattering particles 232 coated with the gel layer may be used alone or in combination.
該發光模組3位於該第一基材21的一側，並可發出該第一色光，該第一色光經由該第一基材21的入光面212進入該散射層23，並激發該等量子點231發出波長大於該第一色光的該第二、三色光，所述各色光經混光後由該第二基材22的出光面222射出。該發光模組3可利用現有的發光二極體作為光源，且可依實際需求選擇所欲發出的色光，於本實施例中，該發光模組3係以藍光發光二極體做為光源，而該藍光發光二極體發出之藍光即為該第一色光。由於該發光模組3的材料選用與細部結構態樣為所屬技術領域者所周知，且非為本發明之技術重點，因此不再多加贅述。The light emitting module 3 is located on one side of the first substrate 21 and can emit the first color light. The first color light enters the scattering layer 23 via the light incident surface 212 of the first substrate 21 and is excited. The quantum dots 231 emit the second and third color lights having a wavelength greater than the first color light, and the respective color lights are mixed and emitted from the light exit surface 222 of the second substrate 22. The light-emitting module 3 can use the existing light-emitting diode as the light source, and can select the color light to be emitted according to actual needs. In the embodiment, the light-emitting module 3 uses the blue light-emitting diode as the light source. The blue light emitted by the blue light emitting diode is the first color light. Since the material selection and the detailed structure of the light-emitting module 3 are well known to those skilled in the art, and are not the technical focus of the present invention, they will not be further described.
本發明該第一實施例利用較短波長的該第一色光(藍光)激發該等量子點231產生波長較長的該第二、三色光(紅、綠光)，進而藉由混光的方式形成白光，最後由該出光面222向外發出。此外，該第一實施例由於該等散射粒子232的設置，可有效地增加該第一色光激發該等量子點231的機率，而提升該第二色光與第三色光(紅光與綠光)的強度，進而使得該發光裝置1發出的白光因該紅、綠光被補足而獲得提升，達到廣色域的目的。The first embodiment of the present invention uses the first color light (blue light) of a shorter wavelength to excite the quantum dots 231 to generate the second and third color lights (red, green light) having a longer wavelength, and further, by mixing light. The method forms white light and is finally emitted outward from the light exit surface 222. In addition, the first embodiment can effectively increase the probability that the first color light excites the quantum dots 231 due to the arrangement of the scattering particles 232, and enhance the second color light and the third color light (red light and green light). The intensity of the white light emitted by the light-emitting device 1 is enhanced by the red and green light to achieve a wide color gamut.
