  • Publication number: 20240122069
    Abstract: The present disclosure relates to a plurality of host materials and organic electroluminescent devices comprising the same. The present disclosure may provide a plurality of host materials having a composition favorable to thermal denaturation due to a low deposition temperature, while improving hole properties and electronic properties of HOMO and LUMO, by comprising separate compounds represented by formulas 1 and 2 into a light-emitting layer. By comprising the plurality of host materials of the present disclosure, it is possible to provide an organic electroluminescent device having a lower driving voltage, higher luminous efficiency and/or longer lifetime.

  • Patent number: 8243755
    Abstract: Disclosed is an apparatus and a method for receiving and playing Digital Multimedia Broadcasting (DMB) data using a DMB package and a mobile terminal. The DMB package is separable from the mobile terminal and can be interfaced with the mobile terminal. The apparatus includes DMB package for receiving DMB data, converting data formats of the received DMB data into multimedia data formats which can be reproduced by the typical mobile terminal, and transmitting the DMB data converted into the mobile terminal reproducible data formats to the mobile terminal. Accordingly, even a mobile terminal, which does not have a function of receiving and reproducing DMB data, can reproduce the DMB data.

  • Publication number: 20050047417
    Abstract: A multimedia reproduction apparatus in a mobile communication terminal comprising: a data parsing section for dividing multimedia data into video data and other data and then parsing the video data and the other data; a video data processing section for decoding the parsed video data; a media delay output controller for delaying the other data parsed by and transmitted from the data parsing section according to buffering information of the video data processing section, for outputting the delayed data, and for generating a synchronizing signal; an audio data processing section for decoding and outputting audio data from among the other data output from the media delay output controller; a video data output section for reading and outputting the video data; and a synchronizing section for synchronizing and outputting the video data.
