Description of the invention: [Technical field to which the invention pertains] Generation: an organic electro-optic device, especially the effective rate and color (four) and degree of the organic source of a white light source [Previous technology] Organic electro-optic device coffee anie EleetrQiumines acid e:i:e, 〇LED) Since ι987 by the United States Kodak company c w.Tai ^ pain t brush Lache vacuum steaming form - with self-illumination Sex, high-catch, re-reading, thin thickness, low power consumption, wide viewing angle, high brightness and full color organic electroluminescent components (〇led) Optical components have been regarded as the star products of the display industry. We don't want to use it as a full-color display or a white light source to achieve an ideal lighting environment that can be both green and energy efficient. The conventional white light organic electroluminescent device, as shown in the first drawing, is a structure disclosed in "White organic electroluminescent devices with improved stability and efficiency" of the US Patent No. 6,696, 177, the organic electroluminescent light thereof. The device 1 is mainly provided with a first electrode (such as IT0) 13, a hole injection layer (HIL) 12, a hole transport layer (HTL) 14, a light-emitting layer (EL) 15, and an electron transfer on a substrate. The layer (ETL) 16 and the second electrode 19 are doped with a guest illuminator 41 in the hole transport layer 14 or the electron transport layer 16. When an external processing 1308467 is used as a current between the f-electrode 13 and the second electrode 19, the luminescent layer 15 is colored (8), such as blue light, and the luminescent 141, 141, also produces a first color (7), such as yellow light. It is then mixed by blue light (8) and yellow light (y) to become a white light source (w). Although the conventional organic electroluminescent device 10 can achieve the purpose of generating a white light source, it is mixed by the blue light γ generated by the light-emitting layer 15 and the yellow light γ generated by the guest phosphor 141 to generate a white light source w. As shown in Figure 2, the light _ ° map is obviously a two-wavelength white light source. In subsequent applications, there will be a defect in light source utilization and poor light color saturation. In addition, there is another organic electroluminescence device for f. In order to achieve the purpose of generating a three-wavelength white light source, it is a structure in which three luminescent layers f are stacked, or it can generate __ The illuminating layer of the three-color light is in the town. Moreover, a first color light guest illuminant can be generated. However, the above-mentioned conventional organic electroluminescence device is not very difficult to manufacture, that is, there is a difficulty in controlling the doping concentration of the guest illuminant, low luminous efficiency or poor service life. [Invention] For this reason, how to solve the problems encountered in the above-mentioned conventional technology, the organic electro-excitation device of the phase is designed, which not only can effectively improve the effective color and degree of the light source, but also effectively simplify (4) and extend the use of the temple. This is the focus of the invention of the present invention. The main purpose of the present invention is to provide an organic electroluminescent device that can have different first-color and second-color lights by using two guest structures having the same chemical main structure but each having a different substituent 1308467. The third color light generated by the other-light-emitting layer is co-produced—the white light source having three wavelengths can not only be covered by the wavelength distribution but also close to the natural white color, and the effective utilization rate of the light source can be improved. Color saturation. A secondary object of the present invention is to provide an organic electroluminescence device capable of doping a first guest-light emitter and a second guest illuminant having the same chemical main structure in the luminescent layer, and thus generating a first color ray and The second color light, this can effectively simplify the production process and improve the life of components. s Jinke, = the purpose of the ‘is to provide the energy and mechanical excitation light with color filter, light film, thin film transistor substrate, color layer or package cover, in order to expand its meaning and scope of application.

貴審查委員對本發明之特徵 結構及所達成 1308467 之功效有進一步之瞭解與認識，謹佐以較佳之實施圖例及 配合詳細之說明，說明如後： 首先，請參閲第3圖，係為本發明有機電激發光裝置 一較佳實施例之構造剖示圖；如圖所示，本發明有機電激 發光裝置3 0主要係於一基板31上設有一第一電極3 3，例 如ΠΌ，而第一電極33上及未設有第一電極33之部分基 板31表面可設有至少一發光層（EL):第一發光層35及/ 或第二發光層37,而發光層35/37上則再設有一第二電極 39。當然，第一電極33及第二電極39之間亦可選擇設有 一電洞注入層（HIL)32、一電洞傳輸層（HTL)34、一電子傳 輸層（ETL)36或電子注入層（EIL)38。該第一發光層35將 可在一工作電流通過時產生一第三色光，例如藍光（B)。 該第二發光層37内則至少包括有一主發光體（Host Emitter ;未顯示）及兩個摻雜之客發光體（Guest Emitter):第一客發光體371(實點所示）及第二客發光體 372(十字點所示），而兩個客發光體371/372又可在工作 電流通過時分別產生一第一色光及一第二色光，例如綠光 (G)及紅光（R或橘光）。又，第三色光（B)、第一色光（G) 及第二色光（R)則可混合搭配以成為一具有三波長之白色 光源（W)。 本發明所摻雜之兩個客發光體371/372,如第4 A圖 及第4B圖所示，都係為一香豆素（Coumariη)之衍生物， 其中第一客發光體371在此實施例中係選擇為一 Coumarin 6 (C-6)材料，而第二客發光體則為一 NKX2221材料 8 1308467 (Hisayoshi Fujikawa, R&D Review of Toyota CRDL, 2002 Vol. 37 No. 3)，兩者皆具有一相同之化學主結構（major structure)40，但也各自擁有一不同之取代基 (substitute group)，例如第一客發光體371中存在有一 第一取代基（或可稱綠光取代基或藍綠光取代基）41，而第 二客發光體372則存在有一第二取代基（或可稱橘光取代 基或紅光取代基）42，藉由相同之化學主結構40，可致使 客發光體371/372容易在第二發光層37中得到近乎相同 之能量激發，以提高製作時之方便性。再藉由不同之取代 基41/42 ’可致使第一客發光體371及第二客發光體372 以相對應產生不同之第一色光（綠光G)及第二色光（橘光 R)’以方便與第三色光（B)共同成為一具有三波長之白色 光源（W)，波長分佈較廣而貼近於自然白光，其光譜圖如 第5圖所示’具有明顯之Blue、Green、Red三個波峰， 因此，也有利於光源的有效利用率及色彩飽和度者。 又’由於本發明之兩個客發光體371/372之化學主結 構40相同，僅在取代基41/42之搭配上有所不同，再加 上第二發光層37之主發光體並不需要產生有利用性之色 光，因此，在主發光體及客發光體371/372之摻雜濃度要 求上並不需要十分準確。且，第一客發光體371及第二客 叙光體372之摻雜濃度也可選擇採用相同濃度或不同濃度 者，因此，在製作上將相較習用有機電激發光裝置更為簡 便。 又，除了岫述之C-6具有一綠光取代基或一藍綠光取 9 1308467 代基41，且可產生綠光或藍綠光外，舉如像美國專利第 4,769,292 號（Eastman Kodak Company)、美國專利第 6, 020, 078 號（Eastman Kodak Company)、美國專利第 2004/0140762 號（Tohoku Pioneer Corporation)、臺灣專 利第593636號（C. H. Chen)或C. H. Chen等發表於 Eurodisplay 2002 Conference, Oct 1-4, 2002, Nice, France.等文獻中所揭露之 C-153、C-525、C-525T、 C-525TB 、 C-545 、 C-545T 、 C-545TB 、 C-545MT 、 C-545P 、 C-545PT、C-545ET、C-545BT、C-6M、C-6E 或 C-7 等材料（上 述所有元件之字母C亦可以Coumar i n替代），也同樣具有 相同之Coumar iη化學主結構40及一相對應可產生綠光之 第一取代基41，因此，這些綠光客發光體材料或藍綠光發 光材料亦可作為一第一客發光體3 71。 同理，除了前述之ΝΚΧ2221材料具有一橘光取代基或 紅光取代基42，而可產生橘光或紅光外，舉凡在同一文獻 中（Hisayoshi Fujikawa, R&D Review of Toyota CRDL， 2002 Vol. 37 No. 3)所提及之 NKX2220、NKX2222 或 NKX2241 等材料，也同樣具有相同之Coumar in化學主結構40及一 相對應可產生橘光或紅光之第二取代基42，因此，這些橘 光客發光體材料或紅光客發光體材料也可作為一第二客 發光體372。 另外，於美國專利第2003/0072890號（Seiko Epson Corporation)、美國專利第 6, 330, 262 號（The Trustees of Princeton University and The University of Southern 1308467The reviewers have a better understanding of the features of the present invention and the effects of the 1308467. The best examples and detailed explanations are given below. First, please refer to Figure 3 for A schematic cross-sectional view of a preferred embodiment of the organic electroluminescent device of the present invention; as shown, the organic electroluminescent device 30 of the present invention is mainly provided with a first electrode 33, such as germanium, on a substrate 31. The surface of the first electrode 33 and the portion of the substrate 31 not provided with the first electrode 33 may be provided with at least one light emitting layer (EL): a first light emitting layer 35 and/or a second light emitting layer 37, and the light emitting layer 35/37 Then, a second electrode 39 is further provided. Of course, a hole injection layer (HIL) 32, a hole transport layer (HTL) 34, an electron transport layer (ETL) 36, or an electron injection layer may be selectively disposed between the first electrode 33 and the second electrode 39. EIL) 38. The first luminescent layer 35 will produce a third color of light, such as blue light (B), as a working current is passed. The second illuminating layer 37 includes at least one main illuminator (Host Emitter; not shown) and two doped guest illuminators: a first guest illuminator 371 (shown by a solid point) and a second The guest illuminator 372 (shown as a cross point), and the two guest illuminants 371/372 can respectively generate a first color light and a second color light, such as green light (G) and red light, when the working current passes. R or orange). Further, the third color light (B), the first color light (G), and the second color light (R) may be mixed and matched to form a white light source (W) having three wavelengths. The two guest emitters 371/372 doped by the present invention, as shown in Figures 4A and 4B, are derivatives of a coumarin, wherein the first guest emitter 371 is here. In the embodiment, a Coumarin 6 (C-6) material is selected, and the second guest illuminant is an NKX2221 material 8 1308467 (Hisayoshi Fujikawa, R&D Review of Toyota CRDL, 2002 Vol. 37 No. 3). Both have the same chemical major structure 40, but each also has a different substituent group, for example, there is a first substituent in the first guest illuminant 371 (or can be called green light) a substituent or a blue-green light substituent) 41, and a second substituent (or may be referred to as an orange substituent or a red light substituent) 42 in the second guest emitter 372, by the same chemical host structure 40, The guest illuminant 371/372 can be easily provoked with nearly the same energy excitation in the second luminescent layer 37 to improve the convenience in fabrication. The first guest illuminator 371 and the second guest illuminator 372 are caused to have different first color lights (green light G) and second color lights (orange light R) by different substituents 41/42'. 'To facilitate the formation of a white light source (W) with three wavelengths together with the third color light (B), the wavelength distribution is wider and close to natural white light, and its spectrum is as shown in Fig. 5, which has obvious Blue, Green, Red three peaks, therefore, are also beneficial to the effective utilization of light sources and color saturation. Further, since the chemical main structures 40 of the two guest emitters 371/372 of the present invention are the same, only the combinations of the substituents 41/42 are different, and the main emitter of the second light-emitting layer 37 is not required. The use of color light is utilized, and therefore, the doping concentration requirements of the main illuminant and the guest illuminant 371/372 do not need to be very accurate. Moreover, the doping concentration of the first guest illuminant 371 and the second guest illuminant 372 can also be selected to be the same concentration or different concentrations, and therefore, it is easier to manufacture than the conventional organic electroluminescent device. Further, in addition to the C-6 having a green light substituent or a blue-green light taking the 1 1308467 base 41 and producing green or blue-green light, as in U.S. Patent No. 4,769,292 (Eastman Kodak Company) ), US Patent No. 6, 020, 078 (Eastman Kodak Company), US Patent No. 2004/0140762 (Tohoku Pioneer Corporation), Taiwan Patent No. 593636 (CH Chen) or CH Chen, etc., published in Eurodisplay 2002 Conference, Oct 1-4, 2002, Nice, France.

Therefore, the green light emitter material or the blue-green light-emitting material can also serve as a first guest light emitter 713. Similarly, in addition to the aforementioned ΝΚΧ2221 material having an orange substituent or a red substituent 42, which can produce orange or red light, in the same literature (Hisayoshi Fujikawa, R&D Review of Toyota CRDL, 2002 Vol 37 No. 3) The materials such as NKX2220, NKX2222 or NKX2241 also have the same Coumar in chemical main structure 40 and a second substituent 42 corresponding to orange or red light. Therefore, these The orange light illuminant material or the red light illuminant material can also serve as a second guest illuminator 372. In addition, U.S. Patent No. 2003/0072890 (Seiko Epson Corporation), U.S. Patent No. 6,330,262 (The Trustees of Princeton University and The University of Southern 1308467
