Zusammenfassung:	The invention disclosures a packaging method of an LED display. The packaging method comprises the following steps: a. providing a packaging support or a base plate; b. die bonding; c. wire bonding; and d. sealing. The sealing comprises steps as follows: d1. a forming die chamber which is matched with the packaging support or the base plate is selected; d2. liquid epoxy resin is potted in the forming die chamber; d3. the packaging support or the base plate is filtered in industrial acetone; d4. the packaging support or the base plate is taken out and dried; d5. the packaging support or the base plate is slantwise put in the forming die chamber and is compressed; and d6. the packaging support or the base plate is baked to solidify the epoxy resin. The packaging method can effectively control the generation of gas bubble, and has the advantages of high operation efficiency and simple operation. LED displays packaged by the method provide uniform light.
