Abstract: The present disclosure relates to an organic electroluminescent compound, a plurality of host materials, and an organic electroluminescent device comprising the same. By comprising the compound according to the present disclosure or by comprising a specific combination of compounds according to the present disclosure as a plurality of host materials, it is possible to produce an organic electroluminescent device having improved driving voltage, luminous efficiency, and/or lifetime properties compared to the conventional organic electroluminescent devices.

Abstract: Disclosed is a high voltage output device having a serial-parallel stack structure of capacitors. The high voltage output device includes a substrate includes a capacitor element and a pillar structure provided on an upper surface of the substrate. The substrate includes a first electrode and a second electrode, which have different potentials from each other. The capacitor element is connected to at least one of the first electrode and the second electrode.

Abstract: The authentication method of a block chain authentication module includes: receiving an authentication preparation request; configuring a channel and generating a channel key allocated to the channel; generating a block including an authentication comparison data, the block further including a block key allocated to the block; commonly transmitting the channel key and the block key, and dividing and transmitting the authentication comparison data; transmitting an authentication preparation completion message including the channel key and the block key; receiving an authentication request message including the channel key, the block key, and authentication target data; dividing and transmitting the authentication target data; receiving a result of comparing the divided and transmitted authentication comparison data with the divided and transmitted authentication target; and determining whether the authentication of the terminal succeeds.
