  • Publication number: 20190131567
    Abstract: The present application provides an encapsulation method for an OLED and an encapsulation structure of an OLED. In the encapsulation method for an OLED of the present application, by disposing the UV light absorbing layer on the surface of the OLED device, in one aspect, the UV light absorbing layer has a low UV transmittance. Therefore, UV light can be blocked from being directed to the TFT during UV curing of the encapsulation material and the sealant to reduce or eliminate the influence of UV light on the TFT; on the other hand, the UV light absorbing layer has high visible light transmittance and therefore does not reduce the light intensity of the OLED device. The encapsulation structure of the OLED of the present application is fabricated by the above encapsulation method. The TFT has excellent electrical performance and the OLED device thereof has strong light intensity.

  • Patent number: 10181579
    Abstract: The present disclosure relates to an OLED encapsulation method and an OLED encapsulation structure. The OLED encapsulation method combines the frame glue encapsulation technology and the thin film encapsulation technology. By adopting the frame glue to block the organic layer and to limit the dimension of the organic layer, each of the organic layers can be completely covered by the inorganic layer arranged thereon. At the same time, the inorganic layers may be manufactured by the same mask, which reduces the number of the mask so as to reduce the cost.
