[Previous technology] General organic electroluminescence device The basic structure, as shown generally in Figure 1, is a light-emitting unit 22 covered with a top surface of a substrate 21 made of glass or transparent plastic. The light-emitting unit 22 is an organic electroluminescent diode arranged in a matrix pattern. The body 221 (〇rganic Ught-Emitting Diode, abbreviated as 0LED), for the overall light-emitting device, each 〇LED is-can be controlled by day and night (pixel), because the basic structure of 〇LED has been related It is well-known in the industry 'the following will not be disclosed and explained in detail. Excluding that if the LED in the light-emitting unit 22 is affected by moisture, it will easily affect the operation function. Therefore, in order to prevent the light-emitting unit 22 from being affected by moisture, a (long) box-shaped rubber strip 23 is glued on the top surface of the substrate 21, The glue strip 23 is enclosed and surrounded around the light-emitting unit 22, and a cover 24 is used to join the top surface of the glue strip 23, so that the light-emitting unit 22 is closed in the enclosed space surrounded by the substrate 21, the cover 24 and the glue strip 23 Within 20. In addition, the light-emitting device further forms a cavity 241 on the bottom surface of the cover 24 facing the light-emitting unit 22, and installs a moisture-absorbing layer 25 containing a hygroscopic agent in the cavity 241. The moisture-absorbing layer 25 absorbs moisture to ensure light emission. The unit 22 is not affected by moisture. The structure design of the conventional organic electro-excitation light device equipped with a moisture absorption layer 25 can achieve the effect of preventing the light-emitting unit 22 from being wet, but because the σ of the moisture absorption layer 25 is placed again, it must be opened on the bottom surface of the cover 24 The recesses 241 and 1241860 are generally made of sand or _, which causes the flatness, light transmittance, and processing of the cover 24, and the moisture absorption layer 25 itself will block the light. These factors are not good for The light emitting unit 22 is issued from this side, that is, only the substrate 21 side is suitable as the light emitting surface, and the cover 24 side is not suitable. [Summary of the Invention] In view of this, the object of the present invention is to provide an organic electrical excitation device provided with a moisture-proof structure that does not affect the flatness, light transmittance and strength of the cover. ίο 15 Yu Li, the organic electroluminescent device of the present invention includes: a substrate, a cover located above the substrate, and a connection between the silk-bonded substrate and the cover: Zao Fan, "a light-emitting unit coated on the substrate And a main hygroscopic body for absorbing water vapor. The light-emitting unit is covered on the top surface of the substrate and includes an organic electroluminescent diode arranged in a matrix pattern. The bonding unit includes a fixed connection Fortunately, the main board seals the door of the substrate tray. + 7 The main seal of the package and the seal, the main seal is enclosed around the light-emitting unit. The cover is located at the light-emitting unit. Above, the cover and the base plate and the main sealing strip jointly define a closed space. The main suction unit H m and the wet body are fixed on the bottom surface of the cover, and are located in the space and surround the light. Around the unit. The effect of the present invention is that the main absorbent body is provided around the periphery of the light-emitting unit to provide a very good hygroscopic effect without affecting the luminosity and intensity of the cover. X, transparent [Embodiment], ~ / 入Six points of Liutazishu, pay a little bit of effect, In the following detailed description of the four light-duplex slave embodiments with reference to the drawings, 20 1241860 will be clearly understood. As shown in FIGS. 2 and 3, the embodiment of the organic electroluminescence device of the present invention includes a substrate 3 , Shibian + Lebananjia 4 peddle 3, a light-emitting unit covered on the substrate 3: a multi-port joint single Fan 5,-a sealing disc 6 fixed on the joint unit 5, and-for The main moisture absorbing body 71 that absorbs moisture. The sealing substrate 3 can be made of glass or transparent plastic. The finger light prelude 4 includes most of the organic electro-excitation light two-body body arranged in a matrix pattern and covering the top surface of the substrate 3. 41. These organic electro-excitation light-emitting diodes 15 1 are usually coated on the substrate 3 in a thorough manner. 5 Including—the main body glued to the top surface of the substrate 3 = 51. In this embodiment, the main body The sealing strip 51 is in the shape of a rectangular frame f: the thickness is much larger than the thickness of the light-emitting sheet & 4, and is spaced around the light-emitting element 4. The cover 6 is a main seal fixed to the joint unit 5. The top surface of the connection strip M is above the light emitting unit 4. The cover 6 and the substrate 3 and the main sealing strip 51 together define a — In the closed jade room 8. In addition, the cover 6 is flat and the side is flat, and the material of the cover 6 can be glass or ceramic: "or plastic and has a ring groove 61 recessed on its bottom surface, the ring groove It is not necessary for the niche to be continuous in the closed space 8 and surround the annular groove 61. The door ㈤ The main absorbent body 71 is fixedly received in the ring groove 61 of the cover 6 and surrounds the light-emitting single opening. The main absorbent body 71 is capable of absorbing water vapor by solid, two: large, and wet materials' to prevent the enclosed space from being wet by the light emitting unit 4 due to the water vapor. 20 ίο 15 20 1241860 By means of this, the distribution of the main absorbent body 71 in this embodiment is around the near edge of the closed space 8 and is located on the periphery of the light-emitting unit *, so it can be invaded by external moisture. When the air space 8 is absorbed by the main absorbent body 71 immediately, the light-emitting unit 4 can be more effectively prevented from being wet. 'Because the main moisture absorption body 71 is arranged around the periphery of the light emitting sheet S 4, that is, the bottom of the cover 6 corresponding to the light emitting unit 4 is not opened: it affects the flatness, light transmittance and intensity. It has a cavity structure, so not only Mao Guangdan 70 4 can emit light from the substrate 3 side down, but also upward from the cover 6 side, that is, the entire organic electrical excitation light I can be applied through this setting.

" As shown in FIGS. 4 and 5, the second preferred embodiment of the organic electro-optical excitation device of the present invention is different from the aforementioned first embodiment in that the bonding unit 5 further includes—bonded to the substrate 3 and the The strips M are joined within 6 of the lids. The main and inner joint strips 52 are in the form of -large-small (long) box-shaped bodies, and the strips 52 are closer to the two first than the main sealing strip 51 and the main absorbent body 71 ... The annular groove 61 on the bottom surface of the cover 6 is interposed between the main sealing strip and the inner joint strip 52, that is, the main absorbent body 71 is between the f strip 51 and the inner joint strip 52. With respect to the light emitting unit 4,. The main absorbent body 71 is also around the periphery of the light emitting unit it 4. With this, when external moisture intrudes into the light-emitting unit 4, the sealing strip 51 of the sealing strip 51 passes through the main body after passing through the main body ... When the moisture—through the main sealing strip Η, blocks; in the main: the main absorbent body 71 to absorb, and the inner jointing strip 52 inside the main absorbent body 71 'can further enhance the effect of blocking moisture. 24186〇, 7 of FIG. 6 " " " " " " " " " " " " " " " " " " " That is to say, the design / requirement / article 52 is not enclosed in the main absorbent body 7 丨 the inner circumference is absolutely 10 15 ^ As shown in FIGS. -7 and 8, the fourth preferred organic electroluminescent device of the present invention The difference between the first embodiment and the second embodiment lies in that: the organic electro-excitation light-emitting junction contains an auxiliary moisture absorbing body 72, and the bottom surface of the cover 6 is further recessed with a long box-shaped auxiliary ring groove surrounding the main sealing strip 51. 62. The auxiliary ring ^ is used to receive the auxiliary absorbent body 72. In addition, the bonding unit 5 ^ includes an auxiliary sealing strip ^ bonded between the substrate 3 and the cover 6, and the auxiliary sealing strip 53 surrounds the periphery of the auxiliary ring groove 62 at intervals. Assist 21b 7 The external moisture wants to invade the secret element 4, and it must pass through the auxiliary sealing strip 51 after the moisture. When the moisture passes through the auxiliary sealing strip 53 and the main sealing strip 51, it will pass through the auxiliary absorbent body 72 respectively. It absorbs with the main thirsty body '. Therefore, the design of this embodiment has a dual moisture absorption effect, and can significantly improve the moisture-proof effect of the light-emitting unit 4.
