Latest Patents

One of Taewoo Jeon's latest patents is an organic electroluminescence device. This device includes an anode, a cathode, and a light-emission layer. The light-emission layer consists of a stack of a blue light-emission layer and a red/green light concurrent-emission sub-stack. The red/green light concurrent-emission sub-stack features a stack of a red light-emission layer and a green light-emission layer. The red light-emission layer contains a red host compound that includes an arylamino group-substituted spirobisfluorene compound. Additionally, the green light-emission layer contains a green host compound that is a mixture of a first green host compound and a second green host compound. The first green host compound is based on a bis-carbazole compound, while the second green host compound is a carbazole-based compound.

Another significant patent by Jeon is for an organic light-emitting display device. This device provides an organic light-emitting element corresponding to each pixel region. The organic light-emitting element includes a hole transport layer, a first light-emitting layer, a second light-emitting layer, a third light-emitting layer, a fourth light-emitting layer, and an electron transport layer. The first light-emitting layer contains a first dopant corresponding to a first color and a first host. The second light-emitting layer includes a second dopant corresponding to a second color, which is different from the first color, and a second host that differs from the first host. The third light-emitting layer incorporates the first dopant and the second host, while the fourth light-emitting layer includes the second dopant and the second host.
