It can be divided into J, knife organic electroluminescent display according to the molecular weight of organic functional materials. Small Molecule OLED Display; SM-OLED Display) and Polymer Light_Emitting Device (PLED Display) are two major categories. The light-emitting structure is composed of a pair of electrodes and a layer of an organic functional material. When a current is passed between the transparent anode and the metal cathode, the electrons and holes are combined in the organic functional material layer to jump to the excited state, so that the layer of the functional material of the j can be made different according to the energy level characteristics of the material. The light of the light. Existing organic electroluminescent display devices generally use a cover to protect the organic material layer of the organic material B, and the cover will be made with a moisture absorbent (1). In this way, the above-mentioned moisture absorbent can absorb the water or other substances harmful to the components, thereby increasing the service life of the organic electroluminescent display. However, as the display area of the organic electroluminescent display is gradually increasing, but the thickness portion is gradually thinning, this practice will face many challenges of the 200826727 mountain. For example, when the cover is subjected to an external force, it is easy to cause the moisture-absorbing agent to crush the organic functional material layer because the cover is too large. Therefore, how to provide an organic electroluminescent display to solve the above problems is a desire of manufacturers and users in the field of organic electroluminescent display. SUMMARY OF THE INVENTION Accordingly, one aspect of the present invention is to provide an organic electroluminescent display.

On the other hand, this embodiment also discloses a package structure suitable for an organic electro-active bamboo shoot light display, which is composed of a cover 13 〇 and a reinforcing member 15 。. The cover 130 is disposed on the substrate ιι of the organic electroluminescent display, and the organic electroluminescence of the organic electroluminescent display is between the substrate 11 and the package i i30. The iridium reinforcing member i 50 W is disposed on the side of the cover 130 facing the substrate 11 , and extends from the center of the sealing cover 13 至 to the edge of the cover 130. In the present embodiment, the material of the reinforcing material 150 may be the same as the material of the sealing material. More specifically, the cover 130 can be integrally formed with the reinforcing material 15〇, :: manufactured. For example, the material of the cover 130 and the reinforcement 150 may be glass, metal or plastic. It should be understood that the cover == the material of the strong material is the same, and the material of the cover and the reinforcing material may be not limited to the above, and the skilled artisan should flexibly select it at that time. Tian Ding 200826727 In Fig. 1A, the reinforcing material ι5〇 can be substantially covered with the moisture absorbing agent ι4〇 to cover the surface of the substrate facing the substrate 11〇, thereby filling a large amount of the moisture absorbent 140 as much as possible to extend The lifetime of an organic electroluminescent display. Of course, the selected moisture absorbent has a better moisture absorption effect. The reinforcing material and the moisture absorbent may not cover the surface of the substrate facing the substrate. For example, the above-mentioned moisture absorbent may be a solid moisture absorber (Solid Getter), a slurry moisture absorbent (Geuer) or a liquid moisture absorbent (Liquid Getter), and each of the moisture absorbents has a different suction. The wet effect and the manner of use, the skilled artisan will practice the invention flexibly according to actual needs. Referring to Figure 2A, there is shown a perspective view of an electromechanical excitation light display in accordance with another embodiment of the present invention. As shown in the figure, the reinforcing member 150 of Fig. 2a may further have a ventilation duct 17 through which the reinforcing member 15 is passed. More specifically, the above-described ventilation duct 17G penetrates the reinforcing member 15A to connect the recess 32 and the recess 134 of the adjacent reinforcing member 150. (4) If the moisture absorbent and the reinforcing material are not covered with the surface of the cover facing the substrate, a portion of the organic electroluminescent display will have no moisture absorbent to absorb moisture (for example, the groove 134). The venting duct is capable of conducting moisture in this area to the absorbent. Referring to Figure 2B, there is shown a perspective view of an organic electroluminescent display in accordance with still another embodiment of the present invention. Although in the above embodiment, the gas passages are all linear, the present invention is not limited thereto. In Fig. 2B, the passage pipe 170 may also be curved. Of course, the venting duct can also be in the form of other suitable fields, and the water vapor of the recess 134 can be connected to the moisture absorbing agent 〇4 〇, and FIG. 3, which is still in accordance with the present invention. A schematic cross-sectional view of an organic electroluminescent display of an embodiment. Although the thickness T of the reinforcing member 15 ′ shown in FIG. 1B is smaller than the edge thickness Te of the cover 13 。, as shown in FIG. 3 200826727, the thickness TR of the reinforcing member 150 may also be substantially equal to the cover 13 . The edge thickness TE of the crucible. In the present invention, "substantially" is used to modify the amount of any slight change, but such slight variations do not change its nature. For example, in an embodiment of the present invention, the thickness of the reinforcing material may be substantially equal to the thickness of the edge of the cover. This description is not limited to the thickness of the cover except the thickness of the cover. The organic electroluminescence unit is crushed, and the thickness of the reinforcing material can also be slightly larger than the thickness of the edge of the cover. (:: Referring to Figure 4, there is shown a cross-sectional view of an organic electroluminescent display according to still another embodiment of the present invention. In this embodiment, the organic electroluminescent display further has an edge at the edge of the cover 130. The buffer zone 180 between the grooves 132 (or the moisture absorbent 140) may require two processing steps due to the manufacture of the cover 13 of the present embodiment, and the buffer 18 〇 is able to change the margin between the two machining programs. Large, reducing the difficulty of alignment. Referring to Figures 5A and 5B, respectively, a perspective view of an organic electroluminescent display according to another embodiment of the present invention is shown. The shape is a cross shape, but as shown in FIG. 5 and FIG. 5, the shape of the reinforcing material 15〇 may also be a shape, and the length direction of the reinforcing material 15〇2 may be perpendicular to the longitudinal direction of the organic electroluminescent display. (as in Figure 5) 'or parallel to the length direction of the organic electroluminescent display (as shown in Figure 5). The following is a non-limiting example of the invention to illustrate the efficacy of the invention: Figure 6 and Figure 7 Figure 6 is a schematic perspective view of an organic electroluminescent display without reinforcement, and Figure 7 is a perspective view of an organic electroluminescent display with enhanced 200826727. The edge of the cover 730/830 is first compared. The depth of the groove in which the moisture absorbent is placed 74 〇 / 84 定义 is defined as the groove depth Dc, and the center thickness of the cover 83 加 after the reinforcing member 85 is added is defined as the thickness TR, and the center thickness of the cover 730 Defined as the thickness Tc. In this example, whether it is an organic electroluminescent display with a reinforcing material, or an organic electroluminescent display without a reinforcing material, the groove depth Dc is 〇·25 mm, and the moisture absorbent The distance Rg of the 740/840 from the organic electroluminescent unit is 0.1 mm. Referring to Fig. 8A, a graph of the attractive compressive stress-deformation curve of the vacuum excitation test of the organic electroluminescent display according to an example of the present invention is shown. Curve 910 shows the attractive compressive stress-deformation curve of the organic electroluminescent display with reinforcing material, and curve 920 and curve 930 respectively show the organic electroluminescent display without reinforcing material at different times. The compressive stress-deformation curve of the vacuum suction test is performed, and the curve 94〇 is also the attractive compressive stress-deformation curve of the organic electroluminescent display without the reinforcing material. It is worth noting that the organic electroluminescent light is shown by the curve 910. The cover and reinforcement of the display are made of soda lime, and the cover of the organic electroluminescent display shown by curve 92〇 and curve 930 is also made of a material with limestone. The cover of the organic electroluminescent display shown by curve 930 is made of a material that is free of alkali free. It can be seen from Fig. 8A that the cover is made of a material having a limestone base. Or an organic electroluminescent display with a reinforcing material made of a material that does not have an alkali metal, the central deformation of the cover is significantly less than that of an organic electroluminescent display without a reinforcing material under the same attractive compressive stress. . Referring to Fig. 8B, there is shown a pressure-deformation curve of the organic electroluminescent display after being subjected to vacuum deformation by the vacuum 11 200826727. Among them, the curve 950 shows the pressure-deformation curve of the organic electro-excitation light with the reinforcing material under the attractive compressive stress of -30 Kpa, and the curve 960 shows the reinforcing material. The electromechanical excitation display shows the pressure-deformation curve under the compressive stress of -20 Kpa, and the curve 970 shows the organic electroluminescent display without reinforcement under the attractive compressive stress of -20 Kpa. The pressure deformation curve obtained by the down-pressure deformation test is performed, and the curve 98〇 shows the pressure under the compressive compressive stress of the _2〇Kpa without the reinforcing material's organic electroluminescence display. - Deformation curve. It is worth noting that the cover and reinforcing material of the organic electroluminescent display shown by the curve 95 〇 and the curve 960 are made of a material having a ash talime, and the curve 97 〇 shows that The cover of the electromechanical excitation display is also made of a material having a limestone base, and the cover of the organic electroluminescent display shown by curve 980 is made of a material that is free of alkali. As can be seen from Fig. 8B, regardless of the stress of the suction, the organic electroluminescence display with the reinforcing material has a central deformation amount of the cover which is significantly smaller than that of the organic electroluminescent display without the reinforcement under the same downward pressure.

The experimental data in Table 2 is obtained by applying a load to the organic electroluminescent display and measuring whether the organic electroluminescent display exhibits a dead pixel after the load. Type indicates whether the organic electroluminescent display being tested has a reinforcement. The cover (and reinforcement) of the organic electroluminescent display that was tested by the private test was made of a material with a soda lime or a material that was not tested with Ulkah fVee. The thickness of the center of the cover indicates the thickness of the center of the cover of the organic electroluminescent display to be tested. For example, if tested = organic electricity, the illuminated display is an organic electroluminescent display without reinforcement, and the middle to thickness of the cover refers to The thickness of the cover TC shown in Fig. 6 is the organic electroluminescence display of ς K. The organic thickness of the cover is the thickness of the cover. The thickness of the cover is the thickness of the reinforcement shown in Figure 7 R. He said that the organic electroluminescence light tested showed that the enthalpy produced a dead spot when the weight was 13 200826727. As shown in Table 1, there is a German-made organic electroluminescence display that produces a dead pixel at a load of up to 60 kg. However, the organic electroluminescent display state without the reinforcing material, regardless of its material, causes a bad point when the load is 5 kg.
