However, because OLED devices are very sensitive to water vapor and oxygen, if water vapor and oxygen penetrate into OLED devices, they will chemically react with organic materials, causing OLED devices to fail.
For example, when the OLED device is in working condition, if the device is infiltrated with water vapor, a miniature electrolytic cell will be formed inside the device, and an electrochemical reaction will occur, and the generated reaction gas will separate the metal cathode from the organic functional layer, resulting in device failure.

The invention discloses an electroluminescence display and an encapsulation method thereof. The electroluminescence display comprises a substrate, a cover plate and electronic devices. An encapsulation part is arranged on the surface of one side of the substrate. The cover plate covers the substrate. A first chamber and a second chamber are defined through the cover plate, the substrate and the encapsulation part. The second chamber extends in the circumferential direction of the first chamber. The electronic devices are arranged on the substrate and in the first chamber. The first chamber is filled with inert gas and the second chamber is filled with oil liquid. According to the invention, moisture and oxygen are prevented from entering the electronic devices; the whole system is high sealed; and the service lifetime of the electronic devices is greatly prolonged.
Description
technical field [0001] The present invention relates to the technical field of displays, and more particularly, to an electroluminescent display and a packaging method thereof. Background technique [0002] In the field of display, OLED devices have a bright future. However, since the OLED device is very sensitive to water vapor and oxygen, if the water vapor and oxygen penetrate into the OLED device, a chemical reaction will occur with the organic material, thereby causing the OLED device to fail. For example, when the OLED device is in working condition, if the device is infiltrated with water vapor, a miniature electrolytic cell will be formed inside the device, and an electrochemical reaction will occur, and the generated reaction gas will separate the metal cathode from the organic functional layer, resulting in device failure. It can be seen that water vapor and oxygen penetrating into the OLED device are the main factors affecting the life of the OLED device. Conte...
