For the emissive layers, which must be patterned, the company developed a nozzle printing process that simultaneously prints the red, green, and blue layers.
The transport and emissive layers are the organic equivalentof the indium gallium nitride (In-GaN) thin films used in blue and green LEDs.
The organic films consist of a hole-injection layer, a hole-transport layer, an emissive layer and an electron-transport layer.
The Pure Crystal Emissive Layer sandwiched between the plasma glass and the individual light cells conducts energy more efficiently so each cell is charged and discharged at a faster rate, improving contrast and brightness while using less energy.
A Crystal Emissive Layer sandwiched between the plasma glass and the individual light cells that helps conduct energy more efficiently so that each cell can be charged and discharged three times faster than before.
Material categories covered include the functional OLED materials in the emissive layer and hole/electron transport/injection/blocking layers as well as substrates, electrodes, and encapsulation technologies.
A newly designed Crystal Emissive Layer combines with Pioneer's PureDrive II circuitry to deliver improved contrast ratios that create the best black levels ever seen in a Pioneer plasma television.
In this program entitled, "High Efficiency White Mesh Phosphorescent OLEDs," the Company will work to increase OLED efficiency and brightness by employing novel emissive layer architectures that are enabled through the use of its proprietary OVPD process technology.
For example, in our new patent, 'Azlactone-Related Dopants in the Emissive Layer of an OLED,' the color tuneable azlactone derivatives are distant cousins of the emitting materials used by jellyfish.
The thickness and competition of each LED's emissive layer remains the same.
