Here, Fig. 1B shows a cross-sectional view of an embodiment of an image display system including an electroluminescence element 1; and Figs. 18 and 18 show a method of manufacturing an image display system embodiment. «Monthly test 1A, first a substrate is provided, and the light-emitting unit ELI EL3 is placed on the substrate 1G to emit 1 L3 on the light having different luminous intensities. Generally speaking, light rays u~^ having different luminous intensities are emitted by the hand and the light-emitting paths P1 to P3. Each of the light-emitting units is affixed to the second light-emitting layer 50' sandwiched between a first electrode layer 4'' and the second electrode layer, for example, sandwiched between the anode layer and the cathode layer, respectively. In addition, 0773-A31770TWF; P93096; Chad ^ = forming an insulating layer 70 on the first electrode layer 60, in particular, the insulating layer J 7 can be made of an organic resin material and can be used to cover the edge of the anode layer 40 - Thereby, the anode layer 40 and the subsequently formed cathode layer 60 are prevented from being short. The material of the insulating layer 70 may be selected from the group consisting of nitrite, ft* oxidized stone, and oxidized stone. Next, a compensation layer is disposed along the light-emitting paths Ρι to ρ3 to adjust the light-emission intensity of each of the light-emitting sheets το L1 to L3, thereby outputting a substantially uniform Lu light Lg. In this example, the compensation layer may be disposed above or below the light-emitting units ELI to EL3. • For example, as shown in Fig. 1A, a photosensitive layer 30 having an original light transmittance can be first provided and disposed along the light-emitting paths U to L3, for example, over the light-emitting units ELI to EL3. Next, as shown in FIG. 1B, the photosensitive layer 3 is irradiated with light emitted from the light-emitting units el 1 to EL3, whereby the photosensitive layer 30 is formed as a compensation layer in which the compensation layer is different. The regions 3〇a to 3〇c absorb light rays having different luminous intensities, respectively, thereby changing the original light transmittance, so that the different regions 30a to 30c have different light transmittances, respectively. In a preferred embodiment, the light L1 from the light-emitting unit EL1 has a higher light-emitting intensity, and the light-emitting layer P1 is irradiated along the light-emitting path P1. The light L2 from the light-emitting unit EL2 has The lower luminous intensity 'which illuminates the photosensitive layer 30 along the illuminating path p 2 〇 〇 〇 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变 改变The rate is reduced 'and the different light intensities will also produce different light transmittances' so in different regions of the corresponding light-emitting units EL1, EL2 3〇a, 3〇b 0773-A31770TWF; P93096; Chad 7 1332276't will have different Light penetration rate. In this example, the illuminating photosensitive layer 30' has a lower light transmittance in the first region 30a due to the higher illuminating intensity [I illuminating, whereas the illuminating photosensitive layer 3 〇 in the second The region 30b may not change its transmittance ' or form a higher light transmittance than the first region due to being irradiated by the light L2 of lower luminous intensity. Alternatively, in another embodiment, the photosensitive layer 30 after illumination may be in the first region 3〇a
不改變其光穿透率，而照光後之感光層3〇，在第二區域 3〇b則具有較高之光穿透率。因此，由於具有較高發光強 度之光線L1係通過具有較低光穿透率之第一區域3 〇a， 而具有較低發光強度之光線L2係通過具有較高光穿透率 之第二區域30b，使得發光單元EL1、EL2所輸出之光線 LI、L2獲得不同程度的補償。 其次，使照光後之感光層30,在不同區域中具有不 同光穿透率之特性加以固定，例如，可藉由顯影及/或定 影步驟使照光後之感光層30,之光穿透率特性固定下來。 如上所述’藉由具有不同光穿透率之照光後感光層 3〇’作為補償層，可以對來自發光單元Eu〜EL3之具有非 士 均勾強度之光線L1〜L3進行調整而產生均勻或實質均勾 的輸出光、線L0。在此，，，實質均句，，表示整個顯示面板之 光線光強度偏差在± 1Q%左右，較佳者是光強度偏差在 5%左右，而最佳者是光強度偏差在± 左右。 在一些f施例中，感光層30可以是任何能受光線照 =而改料穿透率之材料’特別是任何能受不同發光強 又之光線照射而改變或降低光穿透率，因而產生不同光 0773-A31770TWF;P93096;Chad 1332276 …穿透率之材料，例如負片、共軛高分子材料、或是鹵化 銀等含銀化合物。 此外，在一較佳實施例中，發光單元ELI〜EL3係包 含一有機電激發光元件，其包含用以產生光線之有機材 料。此處，有機一詞可以是包含純有機材料和有機金屬 材料兩者，而發光層50可以是具有高發光效率之單一純 材料層，例如铭錯合物 Alq3 (Tris-(8-hydroxy quinolinol) Aluminum)可以產生極佳的綠電激發光。 > 在本例中，基底10係用於固持發光單元ELI〜EL3 及連接發光單元至電源之導線。陰極60，或者是陽極40 和基底10，可以是透明材料以使電激發光穿透而可見。 此處透明一詞表示相對於電機發光之穿透率實質上不低 於80%。此外，在一種結構實施例中，設置在基底上的 是陰極而不是陽極，因此，不論是陽極或是陰極和基底， 相對於電激發光而言，都是可透光的。而當陰極和陽極 >連接到電源時，即可藉由發光單元内的電子電洞復合作 用產生電激發光。 請再參閱第1B圖，在本發明之一實施例中，電激 發光元件1〇〇可以是主動式矩陣OLED顯示元件 (AMOLED)，其由複數個晝素組成，因此爲達成實質均勻 的光線輸出，每個發光單元ELI〜EL3可以視為一晝素單 元之次晝素。 再者，以上本發明實施例所述之原理亦可應用於上 部發光型有機電激發光顯示元件或底部發光型有機電激 0773-A31770TWF;P93096;Chad 9 1332276 發光顯示元件。 舉例而言’第2圖係顯示底部發光型有機電激發光 ” 、不兀件120之剖面圖，類似第1B圖 ，〜此娜邮於—透明基底12:=: -層80所覆盍’在本例中’如第1B圖所示之作 之下電極40係由透明導電材料構成，同時，阶之 上電極6〇則由遮光導電材料構成。因此從有機發二二^ 體ELI〜EL3發出之光線會從底部方向射出。 本例之一重要特徵在於以例如貼合之方式於 上形成照光後之感光層32，此感㈣在不同區域呈有 =之光穿透率以調整發光單元EU〜EU所發出非均句 先線之發光強度，藉此可以產生實質均勻之光線輸出L。 元件肺侧卜上部發光財機電激發光顯^ 件130 U面圖，有機發光二極體ELI〜EL3設置於— 基底13上，在本例中’如第1B圖所示之 ' 電極40係由遮光導電材料構成，同時，作為陰極之j 極6〇則由透明導電材料構成。因此從有機發光二極^ EU〜EL3發出之光線會從上部方向射出。 — 光寺徵在於以例如沈積之方式於有機發 先-極體EU〜EL3上形成照光後之感光層34，此 在不同區域具有不同之光穿透率以 光心 如〜犯所發出非均勻光線之發光強度，藉此可^兀 實質均勻之光線輸出Lg。另在本财，所形成產生 係用以覆蓋照光後之感光層心有機發光二二0 0773-A31770TWF;P93096；Chad 10 丄The light transmittance is not changed, and the photosensitive layer 3〇 after illumination has a higher light transmittance in the second region 3〇b. Therefore, since the light L1 having a higher luminous intensity passes through the first region 3 〇a having a lower light transmittance, the light L2 having a lower luminous intensity passes through the second region 30b having a higher light transmittance. The light rays LI, L2 output by the light-emitting units EL1, EL2 are compensated to different degrees. Secondly, the photosensitive layer 30 after illumination is fixed with different light transmittance characteristics in different regions. For example, the light transmittance characteristics of the photosensitive layer 30 after illumination can be obtained by a developing and/or fixing step. Fixed down. As described above, by using the illuminating photosensitive layer 3 〇' having different light transmittances as the compensation layer, the light beams L1 to L3 having the non-uniform hook strength from the light-emitting units Eu to EL3 can be adjusted to produce uniformity or The output light and line L0 are substantially hooked. Here, the substantial average sentence means that the light intensity deviation of the entire display panel is about ± 1Q%, preferably the light intensity deviation is about 5%, and the best one is that the light intensity deviation is about ±. In some embodiments, the photosensitive layer 30 can be any material that can be irradiated with light and has a higher transmittance. In particular, any light that can be irradiated with light of different illuminance changes or reduces the light transmittance. Different light 0773-A31770TWF; P93096; Chad 1332276 ... material of penetration, such as negative film, conjugated polymer material, or silver-containing compound such as silver halide. Further, in a preferred embodiment, the light-emitting units ELI to EL3 comprise an organic electroluminescent device comprising an organic material for generating light. Here, the term organic may be both pure organic material and organic metal material, and the light-emitting layer 50 may be a single pure material layer having high luminous efficiency, such as Alq3 (Tris-(8-hydroxy quinolinol). Aluminum) produces excellent green excitation light. > In this example, the substrate 10 is used to hold the light-emitting units ELI to EL3 and the wires connecting the light-emitting units to the power source. Cathode 60, or anode 40 and substrate 10, may be a transparent material to allow electrical excitation light to penetrate and be visible. The term transparency here means that the transmittance with respect to the illuminance of the motor is substantially no less than 80%. Further, in a structural embodiment, the cathode is disposed on the substrate instead of the anode, and therefore, whether the anode or the cathode and the substrate, the light is permeable to the electroluminescent light. When the cathode and anode > are connected to the power source, the electric excitation light can be generated by the complexing of the electron holes in the light-emitting unit. Referring to FIG. 1B again, in an embodiment of the present invention, the electroluminescent device 〇〇 can be an active matrix OLED display element (AMOLED), which is composed of a plurality of halogens, thereby achieving substantially uniform light. Output, each of the light-emitting units ELI ~ EL3 can be regarded as a secondary element of a single pixel unit. Furthermore, the principles described above in the embodiments of the present invention can also be applied to an upper illuminating organic electroluminescent display element or a bottom emission type organic galvanic 0773-A31770TWF; P93096; Chad 9 1332276 illuminating display element. For example, 'the second picture shows the bottom-emitting organic electroluminescence light', and the cross-sectional view of the non-clamping element 120, similar to the first 1B picture, ~ this is mailed to the transparent substrate 12:=: - layer 80 covered 盍' In this example, the electrode 40 is made of a transparent conductive material as shown in Fig. 1B, and the electrode 6 of the upper layer is made of a light-shielding conductive material. Therefore, from the organic hair-emitting body ELI to EL3 The emitted light will be emitted from the bottom direction. One of the important features of this example is that the photosensitive layer 32 is formed on the upper surface by, for example, bonding, and the sense (4) has a light transmittance of = in different regions to adjust the light emitting unit. The luminous intensity of the first line of the non-equal sentence issued by EU~EU, which can produce a substantially uniform light output L. Elemental lung side upper illuminating energy electromechanical excitation light display 130 U-face diagram, organic light-emitting diode ELI~ EL3 is disposed on the substrate 13, and in this example 'as shown in Fig. 1B', the electrode 40 is composed of a light-shielding conductive material, and at the same time, the j-electrode 6 as a cathode is made of a transparent conductive material. The light emitted by the two poles ^ EU ~ EL3 will go from the upper direction The light temple is formed by, for example, depositing a photosensitive layer 34 on the organic hair-polar body EU~EL3, which has different light transmittances in different regions to be emitted by the light center. The luminous intensity of the non-uniform light can be used to output a substantially uniform light output Lg. In addition, in the present fiscal, the formed light is used to cover the photosensitive layer of organic light after exposure to light 2280773-A31770TWF; P93096; Chad 10丄

Another = is two! 2 or Figure 4, when the first layer of two excitation light: dry: 8 ° or the outer surface of the substrate 12, the entire organic electricity,, ', can be together with this light The photosensitive layer was placed together in a developing 0773-A31770TWF; P93〇96*Chad 11 1332276 liquid tank for development. The use of the illumination light-sensing layer having the T and the fixed light transmittance of the above embodiment allows the light output of the organic electroluminescent display element to be uniformized. - Another alternative embodiment of the present invention is shown in the diagram of Figure 5, which shows a cross-sectional view of an image display system comprising an electroluminescent device 300. In this example, the % of the photosensitive layer after illumination having different transmittances as shown in FIG. 1B has been removed, and the substantially uniform light of the output is replaced by the light emitted by each of the light-emitting units EL 1 to EL3. The difference between L1 and L3 has been converted into the corresponding digital compensation value. The digital compensation value can be stored in a compensation unit of 370 t. For example, the essence of the output can be calculated first: uniform light L0 and each illumination The difference between the luminous intensity of the light emitted by the unit EL i~Eu is converted, and the difference of the luminous intensity is converted into a bit compensation value for the library. Referring to FIG. 5, the electroluminescent element 3 includes a plurality of The pixel unit 31 is arranged in an array form. In this example, • ' contains sub-pixels EL1 to EL3. However, it should be noted that the parent-word refers to the smallest address unit in the display panel, for monochrome display. For the sake of the device, there is no difference between the element or the secondary element. The term secondary element is mainly used on the color display panel. It is generally defined as a part of the element, which can be independently addressed and emit a specific color of light. '- a single color display in a full color display There are three main color sub-tenucins, namely blue, green and: color secondary. For example, the compensation unit 370 includes one for storing the digital supplement 0773-A31770TWF; P93096; Chad 12 1332276. The memory 330, and a display control unit 350 coupled to the memory 330. The sub-pixels ELI to EL3 are addressed by the row driver 320 and the column driver 340, and the row driver 320 and the column driver 340 are complement units. The display control unit 350 controls the display unit 350 to control the line driver 320 to adjust the illumination intensity and output a signal to the secondary ELI to EL3 display image. 5 is the manufacturing method of the electro-optic element 300, except that the photosensitive layer 30' is removed after illumination and is compensated for the single Luyuan 370, and the rest is similar to the electroluminescent element of the first embodiment 1A to 1B. As described, by using the digital offset value, the compensation unit 370 can control the row driver 320 to adjust the illumination intensity of each sub-pixel as shown in FIG. 1B, specifically, the digital compensation value stored in the memory 330. It is used to reduce light with higher luminous intensity or to increase light with lower luminous intensity. Therefore, the overall light output L〇 of the electroluminescent element 300 can be adjusted to be uniform or substantially uniform. Another embodiment of the system can be processed as a display panel 400 or an electronic device 600. The electroluminescent device 100, 200 or 300 shown in Figures 1B to 5 can be incorporated into a display panel. For example, an OLED panel. Referring to FIG. 6, the display panel 400 includes an electroluminescent device 300 of FIG. 5, such as an active electroluminescent device. The display panel 400 can be implemented as part of various types of electronic components (e.g., electronic components 600). In general, the electronic component 600 includes a display panel 400 and an input unit 500. Further, the input 0773-A31770TWF; P93096; Chad 13 1332276 - the input unit 500 is coupled to the panel 400 and provides an input signal (eg, an image). The signal is generated by the display panel 400. The electronic component 600 can be a personal digital assistant (PDA), a notebook computer, a desktop computer, a mobile phone, a car TV (car TV), or a digital camera.
