Description
一種發光裝置，特別是指一種由多個有機發光二極體面板組成混合光而產生新光源之有機發光裝置。A light-emitting device, in particular, an organic light-emitting device that combines light from a plurality of organic light-emitting diode panels to generate a new light source.
發光二極體為現代發展快速的照明技術。而有機發光二極體(Organic Light-Emitting Diode，OLED)為發光二極體產業中重要的一環。早期有機發光二極體如美國核准專利3,172,862號及4,356,429號所揭示，不僅結構複雜、厚度過厚(>1 μm)且操作電壓過高(>100伏特)，因此尚不具有實際應用價值。柯達公司於1987年發表改良之有機發光二極體結構，作法是在兩電極間置入小分子有機發光材料。英國劍橋大學於1900年亦開發出高分子發光二極體(Polymer Light Emitting Diode，PLED)。自此之後，由於廠商積極地投入研究，對有機發光層材料特性的掌握及製程技術開發的飛躍性進展，使有機發光二極體之應用逐漸成形。Light-emitting diodes are fast-developing lighting technologies for modern times. The Organic Light-Emitting Diode (OLED) is an important part of the LED industry. Early organic light-emitting diodes, as disclosed in U.S. Patent Nos. 3,172,862 and 4,356,429, are not only complex in structure, too thick (>1 μm), and have high operating voltages (>100 volts), so they have no practical value. Kodak Company introduced a modified organic light-emitting diode structure in 1987 by placing a small molecule organic light-emitting material between the two electrodes. The University of Cambridge in the United Kingdom also developed the Polymer Light Emitting Diode (PLED) in 1900. Since then, due to the active research of manufacturers, the mastery of the characteristics of organic light-emitting layer materials and the rapid development of process technology development have gradually shaped the application of organic light-emitting diodes.
單重態能階躍遷(Singlet Excited States)及三重態能階躍遷(Triplet Excited States)為有機發光二極體裡兩個重要的發光機制。由單重態回到基態而放光，稱之為螢光(Fluorescence)，而由三重態回到基態而放光，稱之為磷光(Phosphorescence)。此兩種不同的躍遷機制，都可因發光材料選擇而發出不同波長的光波。由於人類肉眼所視為多重波長所構成之多重顏色，並非純粹之單一顏色。因此 如何利用多波長互相之混合，而能使發光顏色隨之調變，為開發有機發光二極體之一重要課題。雖然美國核准專利5,851,063號揭示了一種利用三原色(紅、綠、藍)無機發光二極體混光而產生白光的方法，但是相比於無機發光二極體，有機發光二極體更具有自發光、高亮度、高對比、反應速度快、輕薄可撓曲及結構簡單等優點。且由於其為均勻發光之面形光源，因此更適合用於照明或平面顯示器。Singlet Excited States and Triplet Excited States are two important luminescence mechanisms in organic light-emitting diodes. From the singlet state back to the ground state, the light is emitted, which is called Fluorescence, and the triplet state returns to the ground state and emits light, which is called Phosphorescence. These two different transition mechanisms can emit light waves of different wavelengths due to the choice of luminescent materials. Because the human eye sees multiple colors of multiple wavelengths, it is not a pure single color. therefore How to use the mixing of multiple wavelengths to change the color of the light, is an important issue for the development of organic light-emitting diodes. Although U.S. Patent No. 5,851,063 discloses a method of producing white light by mixing light of three primary colors (red, green, blue) inorganic light-emitting diodes, the organic light-emitting diode has self-luminescence compared to the inorganic light-emitting diode. High brightness, high contrast, fast response, light and flexible, and simple structure. And because it is a uniform light-emitting surface light source, it is more suitable for illumination or flat panel displays.
美國公開專利2008/0284317 A1號揭示了一種利用螢光藍和磷光紅/綠混光的方法。在單一有機發光二極體結構中，包含了發出藍光的螢光層、發出紅光的磷光層和發出綠光的磷光層。由於各發光層材料特性的差異，欲使用單一電流/電壓源驅動各發光層為一困難的工作。美國核准專利7,935,963號揭示了一種上述結構的改良，將螢光層及磷光層分別置於單一有機發光二極體結構的上半區域及下半區域，上下兩區域間以電極隔開，如此令上半區域及下半區域各自可單獨接受不同電源，從而使對螢光層及磷光層的發光控制性增加。然而，此種配置雖可解決無法使用單一電源驅動不同發光層之問題，但因其各層仍在同一結構中，因此其配置上將阻擋發光路徑而使發光效率無法提高。U.S. Patent Publication No. 2008/0284317 A1 discloses a method of utilizing fluorescent blue and phosphorescent red/green light mixing. In the single organic light emitting diode structure, a blue light emitting layer, a red light emitting phosphor layer, and a green light emitting phosphor layer are included. It is a difficult task to drive each of the light-emitting layers using a single current/voltage source due to the difference in material properties of the respective light-emitting layers. U.S. Patent No. 7,935,963 discloses an improvement of the above structure, in which the phosphor layer and the phosphor layer are respectively placed in the upper half region and the lower half region of the single organic light emitting diode structure, and the upper and lower regions are separated by electrodes, so that Each of the upper half and the lower half can individually receive different power sources, thereby increasing the controllability of the illumination of the phosphor layer and the phosphor layer. However, such a configuration solves the problem that a single power source cannot be used to drive different light-emitting layers. However, since each layer is still in the same structure, its arrangement blocks the light-emitting path and the luminous efficiency cannot be improved.
本新型之目的在揭示一種有機發光裝置。利用一第一有機發光二極體單元發出一第一發光區域，一第二有機發光二極體單元發出一第二發光區域，使第一發光區域及第二發光區域混合重疊於一光學件並透過此光學件產生一第 三發光區域。第一發光區域及第二發光區域可視需求選取相同或不同波長光譜。選取相同波長光譜時，可增加第三發光區域的發光強度；選取不同波長光譜時，可自由調配第三發光區域的發光顏色。由於第一有機發光二極體單元及第二有機發光二極體單元具有經過設計之內夾角，使第一發光區域及第二發光區域於光學件混光時可形成加強發光強度均勻之第三發光區域。並且，更可透過對第一有機發光二極體單元及第二有機發光二極體單元各自驅動電壓/電流的調變，使第三發光區域於CIE色度座標上作精確的調控。The purpose of the present invention is to disclose an organic light-emitting device. A first organic light emitting diode unit emits a first light emitting region, and a second organic light emitting diode unit emits a second light emitting region, so that the first light emitting region and the second light emitting region are mixed and overlapped with an optical component. Produce a first through this optics Three light-emitting areas. The first illuminating region and the second illuminating region may select the same or different wavelength spectra as needed. When the same wavelength spectrum is selected, the illumination intensity of the third illumination region can be increased; when different wavelength spectra are selected, the illumination color of the third illumination region can be freely adjusted. Since the first organic light emitting diode unit and the second organic light emitting diode unit have a designed inner angle, the first light emitting region and the second light emitting region can form a third uniform light intensity when the optical member is mixed with light. Light emitting area. Moreover, the third light-emitting region can be accurately adjusted on the CIE chromaticity coordinates by adjusting the driving voltage/current of each of the first organic light-emitting diode unit and the second organic light-emitting diode unit.

為能更敘明本新型實施方式，特輔以圖式作詳細解說。In order to more clarify the implementation of the new model, the special explanation is explained in detail by the drawings.
請參照第1圖，第1圖繪示本新型之有機發光裝置之第一實施例結構側視圖。有機發光裝置100包含一第一有機發光二極體單元101、一第二有機發光二極體單元102及一光學件103。第一有機發光二極體單元101及第二有 機發光二極體單元102之一側互相連接並形成一內夾角104。第一有機發光二極體單元101與虛擬基準面形成一第一傾斜角105，而第二有機發光二極體單元102與虛擬基準面形成一第二傾斜角106。第一實施例中，內夾角104為90度。光學件103一側連接於第一有機發光二極體單元101，另一側連接於第二有機發光二極體單元102。此時，內夾角104、第一傾斜角105及第二傾斜角106總和為180度，因此第一有機發光二極體單元101、第二有機發光二極體單元102及光學件103形成三角形組合。Please refer to FIG. 1. FIG. 1 is a side view showing the structure of a first embodiment of the organic light-emitting device of the present invention. The organic light-emitting device 100 includes a first organic light-emitting diode unit 101, a second organic light-emitting diode unit 102, and an optical member 103. The first organic light emitting diode unit 101 and the second have One side of the organic light emitting diode unit 102 is connected to each other and forms an inner angle 104. The first organic light emitting diode unit 101 forms a first tilt angle 105 with the virtual reference plane, and the second organic light emitting diode unit 102 forms a second tilt angle 106 with the virtual reference plane. In the first embodiment, the inner angle 104 is 90 degrees. The optical member 103 is connected to the first organic light emitting diode unit 101 on one side and to the second organic light emitting diode unit 102 on the other side. At this time, the sum of the inner angle 104, the first angle of inclination 105, and the second angle of inclination 106 is 180 degrees, so that the first organic light-emitting diode unit 101, the second organic light-emitting diode unit 102, and the optical member 103 form a triangular combination. .
第一有機發光二極體單元101及第二有機發光二極體單元102皆為平面狀。因此第一有機發光二極體單元101發射之第一發光區域a及第二有機發光二極體單元102發射之第二發光區域b皆為面形光源。由於三角形組合上配置的關係，第一發光區域a在第一傾斜角105處發光強度最強，在第二傾斜角106處發光強度最弱；相反地，第二發光區域b在第一傾斜角105處發光強度最弱，在第二傾斜角106處發光強度最強。藉此，若第一發光區域a及第二發光區域b屬同一光域，則二者混合重疊於光學件103，能得到發光強度均勻之第三發光區域c。若第一發光區域a及第二發光區域b屬不同光域，則需配合可程式電源輸入，以加強第三發光區域c合成光的均勻度。The first organic light emitting diode unit 101 and the second organic light emitting diode unit 102 are all planar. Therefore, the first light emitting region a emitted by the first organic light emitting diode unit 101 and the second light emitting region b emitted by the second organic light emitting diode unit 102 are all planar light sources. Due to the configuration on the combination of triangles, the first illumination area a has the strongest illumination intensity at the first tilt angle 105, and the illumination intensity is weakest at the second tilt angle 106; conversely, the second illumination area b is at the first tilt angle 105. The intensity of illumination is the weakest, and the intensity of illumination is the strongest at the second tilt angle 106. Thereby, when the first light-emitting region a and the second light-emitting region b belong to the same light region, the two are superimposed and superimposed on the optical member 103, and the third light-emitting region c having uniform light emission intensity can be obtained. If the first light-emitting area a and the second light-emitting area b belong to different light domains, a programmable power input is required to enhance the uniformity of the combined light of the third light-emitting area c.
上述之有機發光裝置可應用於形成多種色光。由於第一有機發光二極體單元101及第二有機發光二極體單元102可各別連接至少一程式化控制電路(未圖式)，達到單獨控制而不會互相影響，因此對於整個有機發光裝置100 之發光調整來說具有很高的彈性。舉例來說，第一有機發光二極體單元101及第二有機發光二極體單元102可自由選取相同顏色或不同顏色之組合。選取相同顏色時，第一發光區域a及第二發光區域b可藉由光學件103的混合重疊，而使發光強度更均勻。選取不同顏色時，第一有機發光二極體單元101及第二有機發光二極體單元102可個別選取由螢光物質、磷光物質或螢光物質與磷光物質混合而發出的各種顏色光線，例如紅色、黃色、綠色、藍色或白色。藉此，利用色相學原理，可使兩種顏色的光線混合而形成第三種顏色。The above organic light-emitting device can be applied to form a plurality of color lights. Since the first organic light emitting diode unit 101 and the second organic light emitting diode unit 102 can be respectively connected to at least one stylized control circuit (not shown), the individual control is achieved without affecting each other, and thus the entire organic light is emitted. Device 100 The illuminating adjustment has a high elasticity. For example, the first organic light emitting diode unit 101 and the second organic light emitting diode unit 102 can freely select the same color or a combination of different colors. When the same color is selected, the first light-emitting area a and the second light-emitting area b can be more uniformly integrated by the mixing of the optical members 103. When the color is selected, the first organic light emitting diode unit 101 and the second organic light emitting diode unit 102 can individually select various color lights emitted by the phosphor, the phosphor, or the phosphor and the phosphor, for example, Red, yellow, green, blue or white. Thereby, using the principle of hue, the light of the two colors can be mixed to form a third color.
請參照第2圖，第2圖繪示本新型之有機發光裝置之第二實施例結構側視圖。本實施例中，有機發光裝置200結構與第1實施例類似。第一有機發光二極體單元201及第二有機發光二極體單元202之內夾角204亦為90度。主要差別在於在第一有機發光二極體單元201在面對光學件203的一側設置第一導光板205；而在第二有機發光二極體單元202在面對光學件203的一側設置一第二導光板206，藉此使第一有機發光二極體單元201及第二有機發光二極體單元202之光萃取效率增加，而使第一發光區域a及第二發光區域b能更為均勻有效地混合重疊於光學件203。Referring to FIG. 2, FIG. 2 is a side view showing the structure of a second embodiment of the organic light-emitting device of the present invention. In the present embodiment, the structure of the organic light-emitting device 200 is similar to that of the first embodiment. The inner angle 204 of the first organic light emitting diode unit 201 and the second organic light emitting diode unit 202 is also 90 degrees. The main difference is that the first organic light-emitting diode unit 201 is provided with the first light guide plate 205 on the side facing the optical member 203; and the second organic light-emitting diode unit 202 is disposed on the side facing the optical member 203. a second light guide plate 206, thereby increasing the light extraction efficiency of the first organic light emitting diode unit 201 and the second organic light emitting diode unit 202, thereby enabling the first light emitting area a and the second light emitting area b to be more The overlap with the optics 203 is performed for uniform and efficient mixing.
請參照第3圖，第3圖繪示依據第1圖中內夾角另一實施例側視示意圖。如第3圖所示，為同時達到光線疊合及減小元件體積，內夾角104可增加為120度。如此使元件厚度可以縮小。當第一有機發光二極體單元101及第二有機發光二極體單元102發光顏色皆為白色時，於內夾角 104為90度時，可得到相較於原始發光為1.42倍之發光面積；內夾角104為120度時，可得到相較於原始發光為1.73倍之發光面積。Please refer to FIG. 3, which is a side view showing another embodiment according to the inner angle in FIG. 1. As shown in Fig. 3, the inner angle 104 can be increased to 120 degrees in order to simultaneously achieve light superimposition and reduce component volume. This allows the component thickness to be reduced. When the first organic light emitting diode unit 101 and the second organic light emitting diode unit 102 are all white in color, the angle is inside. When 104 is 90 degrees, a light-emitting area of 1.42 times that of the original light emission can be obtained; when the inner angle 104 is 120 degrees, a light-emitting area of 1.73 times that of the original light can be obtained.
請參照第4圖，第4圖繪示本新型之有機發光裝置之第三實施例結構側視圖。於有機發光二極體裝置300中，在第一有機發光二極體單元301、第二有機發光二極體單元302及光學件303形成的三角形組合中，在三角形組合兩端分別截斷加入第一反射件304及第二反射件305。第一反射件304一端與第一有機發光二極體單元301連接，另一端與光學件303連接。第二反射件305一端與第二有機發光二極體單元302連接，另一端與光學件303連接。如此形成之五角形組合，目的在使第一反射件304反射第一發光區域a及第二發光區域b之光線；而第二反射件305亦可反射第一發光區域a及第二發光區域b之光線。藉此，使第一發光區域a及第二發光區域b混合重疊而透過光學件303發出之第三發光區域c更為均勻。Referring to FIG. 4, FIG. 4 is a side view showing the structure of a third embodiment of the organic light-emitting device of the present invention. In the organic light emitting diode device 300, in the triangular combination formed by the first organic light emitting diode unit 301, the second organic light emitting diode unit 302, and the optical member 303, the first end of the triangle combination is respectively cut and added to the first The reflection member 304 and the second reflection member 305. One end of the first reflecting member 304 is connected to the first organic light emitting diode unit 301, and the other end is connected to the optical member 303. The second reflection member 305 has one end connected to the second organic light emitting diode unit 302 and the other end connected to the optical member 303. The pentagonal combination thus formed is intended to cause the first reflecting member 304 to reflect the light of the first light emitting region a and the second light emitting region b; and the second reflecting member 305 can also reflect the first light emitting region a and the second light emitting region b.

Thereby, the first light-emitting region a and the second light-emitting region b are mixed and superimposed, and the third light-emitting region c emitted through the optical member 303 is more uniform.
請參照第5圖，第5圖繪示本新型之有機發光裝置之第四實施例結構立體圖。本實施例中，除了第一有機發光二極體單元401及第二有機發光二極體單元402之外，另增加一第三有機發光二極體單元404。第一有機發光二極體單元401、第二有機發光二極體單元402、第三有機發光二極體單元404及光學件403形成一四面體組合。第一發光區域a、第二發光區域b及第三發光區域c混合重疊於光學件404而發出第四發光區域d。藉此，有機發光裝置400於發光顏色上之調配更具彈性，可得到更為精確之配色。 本實施例之應用，可再增加有機發光二極體單元數量或配置其他光學元件，例如可於有機發光二極體單元402與光學件403所形成立體結構中，除了有機發光二極體單元401及有機發光二極體單元402之外的其餘兩截面，設置其他有機發光二極體面板或反射鏡，使多個有機發光二極體單元之發光區域混合重疊於一光學件403。多個有機發光二極體單元可個別調整發光波長，使發光顏色於色度座標上之配色更為精確。同時由於單色有機發光二極體面板製程較混色面板更為簡易，因此就發光系統而言，每單位輸入功率相對應之造價更為低廉。Referring to FIG. 5, FIG. 5 is a perspective view showing the structure of a fourth embodiment of the organic light-emitting device of the present invention. In this embodiment, in addition to the first organic light emitting diode unit 401 and the second organic light emitting diode unit 402, a third organic light emitting diode unit 404 is further added. The first organic light emitting diode unit 401, the second organic light emitting diode unit 402, the third organic light emitting diode unit 404, and the optical member 403 form a tetrahedral combination. The first light-emitting region a, the second light-emitting region b, and the third light-emitting region c are mixed and superimposed on the optical member 404 to emit the fourth light-emitting region d. Thereby, the organic light-emitting device 400 is more elastic in the color distribution, and a more accurate color matching can be obtained. In the application of the embodiment, the number of the organic light emitting diode units or other optical components may be further increased, for example, in the three-dimensional structure formed by the organic light emitting diode unit 402 and the optical member 403, except the organic light emitting diode unit 401. And the other two sections except the organic light-emitting diode unit 402, other organic light-emitting diode panels or mirrors are disposed, and the light-emitting regions of the plurality of organic light-emitting diode units are mixed and superposed on one optical member 403. The plurality of organic light emitting diode units can individually adjust the light emitting wavelength to make the color matching of the light emitting color on the chromaticity coordinates more precise. At the same time, since the monochrome organic light emitting diode panel process is simpler than the color mixing panel, in terms of the light emitting system, the cost per unit input power is relatively low.

FIG. 8 is a diagram showing changes in the light emission spectrum of the second organic light emitting diode unit according to FIG. 1 with the applied power. This new type One of the characteristics of the organic light-emitting device 100 is that the first organic light-emitting diode unit 101 and the second organic light-emitting diode unit 102 can individually adjust parameters such as light-emitting brightness and light-emitting wavelength.

As can be seen from FIG. 8, the luminescence spectrum of the second organic light-emitting diode unit 102 decreases as the power of the external power source decreases, but the wavelength corresponding to the peak does not change with the power of the external power source. Therefore, in terms of the controllability of the color tone, it has an advantage of being easy to control.

The corresponding positional relationship formed by four different conditions A, B, C and D on the chromaticity coordinates can be obtained by theoretical calculation. Among them, the position of condition B on the chromaticity coordinates is very close to the position of pure white light on the chromaticity coordinates. This is shown in one embodiment of the present invention, and a standard white light source on a chromaticity coordinate can be obtained by the improvement of the structure of the organic light-emitting device and the improvement of the dimming method.
