Potential, so it is expected to become the mainstream of the next generation of flat panel displays. An active organic light-emitting display has been actively developed in the prior art by sequentially forming an anode layer, an organic mantle layer, and a cathode layer on a substrate on which a plurality of thin film transistors have been formed. According to this, the organic light emitting element is driven by the thin film transistor. 1301728 13〇55twfl.doc/d 96/11/30 The formation of the above-mentioned organic functional layer is based on the selection of 'organic electroluminescent element according to the molecular weight of the organic functional material' (smaH mQlecule G p For the small molecule molecule organic "Qi Ke (p_er SM ~ G_ and Gao Qing two categories; for example, polymer organic functional materials; ink-jet print), the material is dissolved in the solvent, As the ink used for the inkjet Sit function, it is then subjected to inkjet printing to remove the solvent in the ink or to remove the solvent: only the steps of alignment, inkjet, and curing are required. Because Hemo printing uses less equipment and high material utilization rate, the cost of manufacturing is reduced in one step. This is more to say, in general, when it is difficult to ride an organic functional layer, it blocks the ink in each element. (Organic functional materials) will not interact with the stain = color, so the barrier layer of interstitial ink will be placed between m. See Figure i and Figure 2 'Figure! Green is the organic light-emitting halogen array base = ink: brush Schematic diagram of the process, Figure 2 is a single element of Figure i The inkjet printing process is carried out by spraying the ink in the direction of the arrow 1〇3 by using the inkjet head 1 filled with the hairpin 105 (105a, l〇5b, l〇5c) (105a, lG5b). , 105c) to the pixel 1〇6 on the substrate. Although there is a barrier layer (10) around each of the halogen (10), the ink (105a, l〇5b, l〇5c) is blocked from overflowing to the adjacent halogen 1 〇6, but in the process of ink printing 1301728 13055twfl.d〇c/d 96/11/30, the ink (105a, 105b, l〇5c) is sprayed in the pixel 106, It may be sprayed on the higher-level barrier layer 1〇4·: and these inks (i〇5a, i〇5b, 1〇5c) sprayed on the barrier layer 104: will easily follow the barrier layer 1〇4 flows into the adjacent pixel 1〇6. Therefore, the current inkjet technology to form the organic functional layer of the organic light-emitting pixel array substrate will cause the following problems: ·,,, When the ink sprayed in the pixel is an ink having the same luminescent material, for example, both red, green, or blue, the ink will follow the barrier layer during inkjet printing. Flowing into adjacent pixels causes the film thickness of the light-emitting material layer to be inconsistent. , , , 2 · If the ink sprayed in the adjacent two pixels is different ink of the light-emitting material, for example, red, green Or two of the blue, when inkjet printing, the ink will flow along the barrier layer to the adjacent halogen, causing the problem of mutual color mixing. A" [Invention] In view of this, the present invention The purpose of the invention is to provide an active organic spring light-emitting element to solve the problem that the ink overflow is easily generated when an ink-jet printing process is used to form an organic functional layer, and the film of the organic functional layer is uneven, or There is a problem of color mixing between adjacent pixels.

Referring to FIG. 3 and FIG. 4, each pixel 2〇6 of the active organic light-emitting pixel array substrate of the present invention comprises a thin film transistor/capacitor disposed on the US board 200, and a first electrode 210 and a resistor 202. The organic functional layer 212 and the second electrode 214. In a preferred embodiment, the substrate 200 is, for example, a germanium substrate, a glass substrate, a plastic substrate, or a flexible substrate. In addition, the thin film transistor/capacitor and the first pole 210 are disposed on the substrate 2, wherein the first electrode is connected to one of the thin film transistors. In a preferred embodiment, each element has a switching transistor 10, a driving transistor 2A, and a capacitor 3 (shown in Figure 6). However, the present invention is not limited to the form of the switching transistor 1A and the driving body 35, which may be an amorphous 7 thin film transistor or a polycrystalline thin film transistor. Similarly, the present invention does not limit the form of the capacitor 3〇, which differs depending on the process and design of the transistor. For example, if the transistor is a polycrystalline thin film transistor, the capacitor is under 3〇. The electrode is, for example, a stone material. FIG. 7 is a schematic cross-sectional view showing a thin film transistor connected to a first electrode, which comprises a thin film transistor 210b disposed on a substrate 200, and a first electrode 2i〇a connected to the thin film transistor 2i〇b. The sound insulating film 210b and the barrier layer 2〇2 of the partial first electrode 21〇a are covered. 1301728 13055twfl.doc/d 96/11/30 It is particularly worth mentioning that the number of thin film transistors and capacitors used in the present invention is the same as that used in the first element. And set. For example, the second material is used as an anode, and one of the materials and the indium oxide (4), and the oxidation can also be used as a cathode. The material thereof is, for example, i metal=pole 210a, and the succession is shown in FIG. 3, FIG. 4 and FIG. 7. The thin film transistor, the capacitor, and the second electrode of the respective layers 2G6 in the barrier layer are defined as an opening area on the first electrode 21A, and at least one around the first electrode. Part of the barrier layer 2〇2, /, has a groove 208. In the preferred embodiment, p and the opening area defined by the spacer 2〇2 are, for example, rectangular, elliptical or circular. In a preferred embodiment, the shape of the groove described by Ji is, for example, an elongated shape, and its depth is, for example, less than 0.3 μm. In the preferred embodiment, the thickness of the barrier layer 2 〇 2 where the recess 208 is not formed is, for example, less than 丨 micron. In addition, the material of the barrier layer 202 is, for example, a photoresist material (for example, polyammonium is in another
較佳實施例中,阻隔層202的材質例如是氧化物、氮化物 或是氮氧化物。 由上述之說明可知,由於阻隔層202中係形成有凹槽 208,所以當利用喷墨印刷製程以將有機官能層墨水喷著於 晝素206時,多餘的墨水會流進凹槽208並陷於其中,因 此可以避免墨水流到鄰近的晝素中。 當進行完喷墨印刷製程之後,所形成之有機官能層 212會覆蓋阻隔層202所暴露出之第一電極210上。之後, 所形成之第二電極214則是覆蓋在有機官能層212上,如 11 1301728 96/11/30 13055twfl.doc/d 此即構成完整之主動式有機發光晝素陣列基板之晝素,其 係包括發光二極體40(包含第一電極膜、有機官能層與第 二電極膜)、薄膜電晶體10、20以及電容器30(如圖5所 緣示)。 本實施例之另一種阻隔層之結構如圖8與圖9所繪 示’其係先前所述之圖3與圖4之晝素相似,唯一不同的 是在於阻隔層202表面之凹槽208之側壁係為斜坡狀。In the preferred embodiment, the material of the barrier layer 202 is, for example, an oxide, a nitride or an oxynitride. As can be seen from the above description, since the recess 208 is formed in the barrier layer 202, when an inkjet printing process is used to spray the organic functional layer ink onto the halogen 206, excess ink may flow into the recess 208 and become trapped. Among them, it is possible to prevent the ink from flowing into the adjacent halogen. After the ink jet printing process is completed, the formed organic functional layer 212 covers the first electrode 210 exposed by the barrier layer 202. Thereafter, the formed second electrode 214 is overlaid on the organic functional layer 212, such as 11 1301728 96/11/30 13055 twfl.doc / d, which constitutes a complete active organic light-emitting halogen array substrate, which The system includes a light-emitting diode 40 (including a first electrode film, an organic functional layer and a second electrode film), thin film transistors 10 and 20, and a capacitor 30 (as shown in FIG. 5).

FIG. 10 is a partial structural diagram of a halogen element of an active organic light-emitting halogen array substrate according to another preferred embodiment of the present invention, and illustrates an active organic light-emitting device according to another preferred embodiment of the present invention. A schematic cross-sectional view of one of the elements of the matrix substrate. The pixel illustrated in FIG. 10 and FIG. 11 is similar to the pixel of FIG. 3 and FIG. 4 previously described, except that the groove 2〇8 of the barrier layer 202 further includes another barrier layer 2〇. 4. In a preferred embodiment, the barrier layer 2〇4 does not fill the recesses 2〇8. In one example, the material of the barrier layer 204 is, for example, a photoresist material (for example, polyamidamine). As described above, since the barrier layer 2G2 is formed with a groove, it is recessed in the recess 208. The barrier layer 204 is not filled with the grooves 208, 206 ί, and the organic functional layer ink is sprayed on the halogen to prevent the ink tank 208 from being trapped therein. The same is formed after the inkjet printing process is completed. 1301728 13055twfl.doc/d 96/11/30 Π 覆盖 will cover, the second electrode 214 formed by the first electrode 210 κ ί exposed by the spacer 202 is covered by the organic functional layer The active organic light-emitting halogen array base i includes a light-emitting diode 4Q (including an anode layer:::, a thin film transistor 10, 2°, and a storage capacitor_'. As can be seen from the above, the present invention has the following advantages: In the active organic light-emitting halogen array substrate proposed by Jin, i is concave, so when ink is printed on the ink electrode by the inkjet printing technology, the excess ink will flow into the groove and be trapped in /, so Avoid ink flowing to adjacent pixels. Thanks to Ganben Another type of active organic light-emitting pixel array substrate, layer, 'design has _' and (10) is configured with a barrier: Shi Uli (four) ink printing technology will ink the ink nozzle into each groove will flow into the groove and Entrapped in it: the ink will be flown to the adjacent pixels. j Avoid the limitation: two = 2_ example disclosed above, but it is not used to and Fan Yuan; Therefore, the protection of the present invention [圏=;]_ is subject to the scope defined by the patent.
