INSTRUCTIONS: [Technical field to which the invention pertains] The present invention relates to organic | _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Robust and easier to handle OLED devices. [Prior Art] Traditionally, it has been placed on a thin or ultra-thin glass substrate, which is particularly suitable for forming displays and flexible devices, such as wafer cards. However, the thin glass substrate is fragile and susceptible to damage during manufacture or final assembly of the 〇led devices. U.S. Patent No. 6,66, 547 describes a method of using one of the other types of materials that can be positioned on the upper, lower or both surfaces of a substrate and bonded by epoxy, adhesive or other types of materials. The edges are supported to stabilize the substrate. 〇LED displays on ultra-thin substrates, integrated in wafer cards and other flexible applications can be enhanced by covering the cover as described in U.S. Patent 7, 〇26,758. SUMMARY OF THE INVENTION One object of the present invention is to provide an OLED device that is stronger and easier to handle during manufacturing and final assembly. The spectroscopy is solved by a device formed on a substrate and comprising at least one layer of luminescent material disposed between the first and second electrodes, wherein the substrate has a thickness greater than about 5 mm. Currently, OLEDs are fabricated on thin or ultra-thin glass substrates. Therefore, larger xenon LED devices (e.g., lamps) are typically covered by hardened or safety glass to make them suitable for external applications, security applications, or public spaces, which increase the thickness of such devices to a few centimeters. Because the first 127442.doc 200904243 μ-produced a thin and expensive substrate and then used - thick glass to cover it to meet customer specifications is clearly devious, so the other aspect of the present invention provides a OLED device In accordance with one aspect of the present invention, an LED device is provided that allows for a more robust manufacturing and assembly process. In another aspect of the invention, a method for fabricating a robust and easy to assemble OLED device is provided. In another aspect of the invention, a "LED" device is provided that can be used for illumination, such as public space lighting, exterior lighting, interior lighting, home lighting, or ambient lighting. In another aspect of the invention Providing an OLED device in which no additional protective hard glass coverage is required. This not only reduces production costs but also improves the optical performance of the final product. These and other aspects of the present invention will be described and understood with reference to the following specific embodiments. [Embodiment] In an embodiment of the present invention, a device is provided, wherein at least one layer of luminescent material disposed between the first and second electrodes may be Formed on a substrate having a thickness greater than 5 mm. When compared to a conventional OLED device (a) as shown, for example, the tantalum LED device is stronger and easier during manufacturing and final assembly. In Fig. 1, the luminescent material (e) disposed between the first and second electrodes is deposited on a glass substrate (b) which is usually a 0.7 mm thick soda lime glass substrate. The thin substrate (b) is damaged, a hardened or safety glass thick protective sheet (d) is placed on the OLED device. 127442.doc 200904243 Figure 2 shows one of the inventions according to the invention 眚# η ^ πτ·, " A device (1) can be provided, for example, from a glass (e.g., glass or glass). Other transparent materials (e.g., polylithic households) Acidic or polyethylene terephthalate is also suitable. In an example of the invention: In the embodiment, the substrate is a polished glass. The thickness of the substrate is greater than about 5 millimeters, for example from about 5 millimeters. To 1 mm, or from twentieth to 80 m For example, about 50 mm. f. At least one layer of luminescent material (g) disposed between the first and second electrodes may be formed on the substrate (1) by a conventional method. Usually, the anode may be thin, for example, by The translucent indium tin oxide (ITO) deposited by particle beam sputtering can be deposited on the coated substrate by, for example, evaporation, sublimation or spin coating. Finally, usually by suitable The cathode metal is thermally evaporated or splashed in a vacuum to deposit a cathode layer on the organic layer. The material of the cathode layer may be a non-transparent metal or a transparent material, such as ιτο. In this case, the 〇LED can pass through The two electrodes emit light. Further, the xenon LED device (e) can be sealed by a cover plate (h) to prevent oxygen or moisture from penetrating into the luminescent material. The germanium LED device can be sealed by a cover plate (h) which can be made, for example, of the same material as the substrate (f). This will result in a transparent substrate and electrodes in the OLED that are illuminated on both sides. Such OLEDs can also be used as windows in buildings, facades of buildings, shelves, office partitions, and the like. Such OLEDs can also be used as display devices with structural electrodes and/or one or more light-emitting layers.
