Abstract

An organic inorganic hybrid light emitting diode device includes an inorganic light emitting diode die capable of emitting light of a first wavelength range, and an encapsulating material containing an organic material capable of emitting light of a second wavelength range after being excited. The light emitting diode die is encapsulated inside the encapsulating material. Light in the range of the second wavelength is generated when the organic material in the encapsulating material is excited by part of the light in the range of the first wavelength transmitting through the encapsulating material. Light range of the third wavelength is generated when the other part of the light in the range of the first wavelength emitted by the light emitting diode die is transmitting through the encapsulating material and mixed with the light in the range of the second wavelength.

Description

461125 V. Description of the invention (1) Field of the invention The present invention relates to a light-emitting diode, especially to an organic hybrid light-emitting diode, and particularly to an organic-inorganic light-emitting diode device. Description of related technologies Light-emitting diodes are widely used, such as display devices, traffic signs, data storage devices, communication devices, and medical devices. Potential demand for light-emitting diodes The main one is a white light-emitting diode. If it can reduce the production cost of white hair and increase its service life, it may replace white fluorescent tubes or lamp pain. At present, the most common white light-emitting diode system on the market is a combination of a diode and a phosphorescent material. The principle is to use the blue light emitted by the blue body grains to excite the fluorescent material, so that the latter produces a mixture of the original blue light and becomes white light. . One of the main disadvantages of this prior art white light-emitting diode is that before the light-emitting diode grains are mounted, the fluorescent material must be combined with the individual crystal grains', which results in a complicated manufacturing process and thus production costs. Another disadvantage of this prior art white light emitting diode is that a part of the blue light emitted by the crystal grains of the body does not pass through the fluorescent light and is emitted from the thick side of the light emitting diode crystal, so the yellow light cannot be completely emitted. Now, there is a lack of uneven light mixing. SUMMARY OF THE INVENTION A hybrid white with Qin and non-light is used for optical display, the largest and heaviest light-emitting diode. The blue light-emitting color light-emitting diode produces yellow light. : Luminous Diode in Fengbei leads to a high price: Luminous Di (material, while straight with fluorescent material dots.

Alq3 produces yellow ★, the blue ^ light _ = out of blue ★-partly excite the ^ Wang Xingyuan. The 1-color hair first issued by a polar crystal blue 弁 卩 弁 卩 is through the packaging material and the yellow light Mixing and combining, so the manufacturing process is simple 'and thus can reduce production costs. The body group is another object of the invention is to provide a white light emitting suppressor. The packaging material of Guangzhong is made of epoxy resin and stimulated jealous earth = A: 3, and is packaged with this packaging material. Conventional: ^ :: = bulk crystal, this blue light emitting. The blue light emitted by the diode crystal ^ emits yellow light at one pole, the blue light emitting diode crystal by the blue. Color emitting diode crystal All the blue light emitted by the granules are transparent: It can be emitted, so it can avoid the disadvantages of uneven mixing of light in the previous technique. Materials: Inorganic components: Included in the desires of the mountain. Inorganic hair-producing diodes can be emitted. Monitoring light; and a packaging material, which is a mixture of Alq3 that can emit yellow light, and the light emitting diode 2 is excited and loaded into the packaging material, and the blue light passes through the packaging: material: crystal :: seal One part stimulates the Alq3 to produce yellow light, and the other part of the blue light emitted from the blue light emitting medium is mixed with the i light through the encapsulating material. The invention is issued by the particle. Fat. Ming's Order: Shizheng's Batu Duxin This invention provides a White hair first diode device 'forlorn wherein the encapsulating material present by a majority Long Xi A] nq ,? In addition, 糸 糸 is made of epoxy resin and A 1 q3 which can emit steam after being stimulated. This kind of seal is used to seal #-to identify Yuele, μ „, custom blue used in village packaging. The first light-emitting diode is pulled, the blue light-emitting diode is called the eight, Hong Yixi A 1 Q Ben Λ 4 but one of the blue light emitted by the sun-grain is blue, and the blue light-emitting diode is blue. The ί: ϊ ϋ: ϋ mixed with the yellow light to produce white ": 二" is not limited to the use of white ★, and it is also used to produce _ other colors of mixed light. Nothing is impossible. The inventive concept described in the previous paragraph, according to an organic-inorganic hybrid light-emitting diode device according to a preferred embodiment of the present invention, as shown in FIG. The die 20 includes a gallium nitride-based stacked structure formed on a substrate 21, a p-type electrode 28, and an n-electrode 29. The p-type electrode 28 is connected to a first conductive element U through a wire 3 On a protruding portion 11a, the n-type electrode 29 is connected to a first conductive element 12 through a wire 3, and the packaging material 14 is made of epoxy resin and excited. A 1 q 3 of the light emitted from the page is mixed. Obviously, the manufacturing process of the blue light-emitting diode grains is simpler than that of the previous artist, and all the blue light emitted by it is emitted through the seal 1 material. It can avoid the disadvantages of the complex manufacturing process and the uneven mixing of light and light in the prior art.
