13.3: Using New Driving Method to Reduce Data IC Heat, with the Single Scan Mode, in a 50-In Full HD PDP

In order to improve image quality, there is a need for high definition, which is an increase in vertical lines. However, with such an increase, the data IC heat becomes an issue. The data ER circuit is used to solve this problem. We can eliminate the data ER circuit that is used by using a linear-subfield driving, a new data switching algorithm, and a new subfield mapping in a 50-in full HD PDP with single scan mode.

Synthesis and Electroluminescent Properties of Novel Emissive Iridium Complex with Phenyl-isoquinoline Ligand

ABSTRACT Novel red phosphorescent iridium complex with two phenyl-isoquinoline ligands and one 2-acetyl-cyclopentanone ligand (IR-PIQCP) was designed and synthesized. The electroluminescent (EL) characteristics of IR-PIQCP were evaluated in the EL device. The three kinds of EL devices were fabricated by the vacuum deposition method, and the layer-structures of the devices were ITO/NPD/IR-PIQCP (5%), IR-PIQCP (10%) or IR-BTPAC (10%) in CBP/Balq/Alq/LiF/Al. Emission characteristics of the IR-PIQCP (5%) and IR-PIQCP (10%) devices were about 570 cd/m2 and 550 cd/m2 at 11 mA/cm2 at the same current density respectively. The EL spectra of the IR-PIQCP (5%) and IR-PIQCP (10%) devices were detected at about 627 nm and 629 nm as the maximum peak with red phosphorescence.
