ELECTROLUMINESCENT DEVICE USING THE ELECTROLUMINESCENT COMPOUNDS
摘要
<p>The present invention relates to an electroluminescent device which improves light emission efficiency by improving electron density distribution by showing an efficient energy transfer mechanism between a host and a dopant. Moreover, the device can overcome the early efficiency degradation and short life span of an existing material and can obtain improved light emitting properties with high efficiency and long life time per each color.</p>
