X ^ ^ 1〇 , ^ 下表所示：t 11 , ^ t , mM are supplied and directly applied to the surrounding portion 132, but the pressed substrate 11 and the cover plate 13 are mostly made of glass material, and often have different sizes, so mechanical pressure is applied. The mechanism must be very sophisticated and complicated, resulting in higher cost. The gas pressure shown in the front of η 1 is used to provide back pressure, but because the pressure piece is a thin plate, the process of applying gas back pressure is easy to cause. The cover portion 13 of the cover plate 13 is cut to a lower rigidity, so that the desiccant rate is IV. The reason for the analysis is mainly because when the gas back pressure is applied, in terms of structural mechanics, a pivoting (Hinge) phenomenon occurs in the area indicated by Fig. 1 Easy to bend down.

Therefore, the novel organic electro-optic device comprises: -w only to reverse '- ^ ic ^ φ ^ ^ ^ ^ , a - 1 t ^ # ^ ^ ^ ± square cover. The cover plate defines a recess for receiving the light-emitting unit, and the recess has a central portion and an edge portion, and the concave portion has a concave depth that is shallower than a concave depth at a central portion of the concave portion. The present invention utilizes the edge portion of the recess to increase the thickness of the corresponding portion of the periphery and the edge portion of the cover to improve the resistance of the portion 6 M320273. [Embodiment] The foregoing and other technical contents, features and effects of the present invention are coordinated in the following The detailed description of the preferred embodiment with reference to the drawings will be apparent. In the description, similar elements are denoted by the same reference numerals. I Referring to FIG. 2, FIG. 3 and FIG. 4, a comparative example includes a horizontal substrate 2, a cover 4 covering the substrate 2, and a substrate 4 and a cover 4 formed thereon. The light emitting unit 3 and a desiccant 5 formed on the bottom surface of the cover 4 are provided. The substrate 2 is made of a transparent material. In the embodiment, the substrate 2 is made of transparent glass, but the implementation is not limited to the material of the embodiment. For example, polycarbonate resin (p〇lycarb〇nate) Referred to as pc), and the material of the acrylic 2. A concave portion 4 凹陷 is formed on the bottom surface of the friend cover 4, and the concave portion Μ〇 has a central portion 4〇丨 and an edge portion 4〇2, and the concave portion 4 has a concave depth shallower than the concave portion 402 The concave portion 4 has a concave depth of the central portion 4〇1. The cover plate 4 has a horizontal plate body 41'' spaced apart from the substrate 2, and a surrounding portion 42 projecting downward from the periphery of the bottom surface of the plate portion 41 and having a bottom end abutting on the periphery of the substrate 2. The recessed portion 4 is formed by the surrounding portion similar to the panel portion 41. The surrounding part μ 7 M320273 4 ^ ^ 421, ^ 421 ^ ^ ^ 41 ^ # ^ ^ ^ ^ 40 ^ ^ ^ ^ ^ ^ ^ ^ ^ 422 〇 ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ϋ# ^ ^ 402 〇^ t ^ M t 〇Λ ί ^ 42241 ^ 4〇^ ^ 402 ^ £ P,^ 0 ^ |t^ ^ 5 4 the bottom surface 'and located in the central part of the recess 4〇4〇i Inside. In this embodiment, the total thickness of the cover plate 4 is T, and the side of the surrounding portion 42 is 421^^^a, ^b„ 422 b , which is like the vertical distance from the bottom surface to the bottom surface of the reinforcing region 422 (that is, the side ring region 421). The difference in thickness from the strengthened region 422 is e, the thickness of the desiccant is t, and the thickness a of the side ring region 421 is between the total thickness τ of the cover 4 and the thickness t of the desiccant, that is, T>a>;t, and the thickness difference c between the side ring region 421 and the reinforcing region 422 is greater than or equal to half the thickness of the side ring region 421, that is, C - 0.5a 〇 the light emitting unit 3 is formed on the top surface of the substrate 2 and located at The light-emitting unit το 3 can receive the external power source and the control signal to emit light, and the light is emitted to the outside through the substrate 2. The light-emitting unit 3 is a general photoelectric element EL or OLED, and is not implemented in this embodiment. The type of the example is limited. By this, the reinforcing region 422 is used to increase the overall strength of the cover plate 4, and when the back pressure is applied to the top surface of the cover plate 4 during the packaging process, the plate portion 41 can be prevented from being excessively bent downward. Folding and touching the light-emitting unit 3 causes the light-emitting unit 3 to malfunction 'to increase the production yield. In addition, the desiccant 5 The thickness is less than the thickness of the reinforcing region 422, t < b, to facilitate the attachment of the desiccant 5 to the bottom surface of the plate portion 41. 8 M320273 The following is a reinforced area 422 of the slab 4 The side ring region 421 cooperates to reduce the effect of the lower portion 41 of the plate portion 41. First, the total thickness of the cover plate 4 of the present embodiment is τ^ 〇 7 cm, and the thickness a of the side ring region 421 is 0.3 cm, and the reinforcing region 422 The thickness of the pad is 〇15 cm, and the back pressure applied to the cover plate 4 is 仙肸^ The experimental process is the deformation amount s of the lower portion of the plate 41 bent downward under different 422 4 f Μ plus back pressure, the strengthening region 422 ^ X .

0.0847 由上述之實驗結果可清楚看出強化區域422設置之後 ，板本部41之彎拆變形量s明顯減少，且當強化區域422 之寬度X增加時亦可逐漸減少板本部41之彎折變形量^， 由以上之測試結果證實，強化區域422的設置確實可以於 板本部41受背壓下減少板本部41之彎折變形量，以避免 封I過程中板本部41底面之乾燥劑5觸抵發光單元3，提 呵生產良率。也就是說，可以藉由該強北區域422之設置 確實可以強化板本部41之抗撓強度。 蒼閱圖5，本新型有機電激發光裝置之第二較佳實施例 之構造大致與第一較佳實施例相近，其不同之處在i該蓋 板4之凹部40邊緣部位402是呈複數階狀。亦即該強化區 9 M320273 ^ A22 ^ 41之鄰接處’以強化板本部41之抗撓強度1^^^^^^^^^^^^^^: 參閱圖6 ’本新型有機電激銳 之構足大致契第—較佳實施例相近，其不同之處在於該蓋 板4之凹部40的邊緣部位4〇2是形成斜角狀，亦即該強化 區域422是由該側環區域421往内斜上延魏 本部41底面上’致使該強化區域422於該板本部41底面 A#] ^^421 ^ φ ^ ^ ^ ^0.0847 It can be clearly seen from the above experimental results that the bending deformation amount s of the plate portion 41 is significantly reduced after the reinforcing region 422 is set, and the bending deformation amount of the plate portion 41 can be gradually reduced when the width X of the reinforcing region 422 is increased. ^, It is confirmed by the above test results that the setting of the reinforcing region 422 can reduce the bending deformation of the plate portion 41 under the back pressure of the plate portion 41, so as to avoid the desiccant 5 of the bottom surface of the plate portion 41 during the sealing process. Light-emitting unit 3, to produce production yield. That is to say, the flexural strength of the plate portion 41 can be surely strengthened by the arrangement of the strong north region 422. 5, the structure of the second preferred embodiment of the novel organic electroluminescent device is substantially similar to that of the first preferred embodiment, except that the edge portion 402 of the recess 40 of the cover 4 is plural.
