Abstract
Official abstract text for this publication.
The present invention provides an OLED packaging structure and a packaging method thereof. The OLED packaging structure comprises a packaging board and an OLED substrate. At least one seal frame matching OLED in size is formed through painting glass frit seal on the packaging board at a position corresponding to the OLED. An initial painting point is at every seal frame with a protruding prominence. A recess is set up on the OLED substrate corresponding the initial painting point to accommodate the prominence. the OLED packaging structure and the packaging method thereof is to set up a recess on an OLED substrate to accommodate a prominence on the initial painting point due to accumulation of glass frit seal on a packaging board, so that when adhering the OLED substrate to the packaging board the seal frame is adhesive to the OLED substrate tightly without significant gap. Therefore subsequent laser melding is more successful, to prevent from forming gaps between a packaging board, an OLED substrate and a seal frame, and lifetime of OLED is lengthened.
