OLED lighting

OLED lighting process in addition to evaporation technique, this year has seen much progress in the solution coating process technology.Actively develop the solution coating type OLED lighting technology include Philips / Konica Minolta, LG Chem, UDC and other companies.

Introduction to the OLED package type

Relatively cheaper cost Higher material utilization rate.Solution containing a combination of multi-

component material

The reason why the development of solution coating process OLED lighting technology reasons (control evaporation technique) mainly due to ：

Small molecule materials commonly used in light-emitting materials system (control light-emitting polymer materials system) ：Higher luminous efficiency.Materials easily purified.Batch mass production of materials quality

is good reproducibility.After the coating process, the drying

process, the solvent removed quickly and solvent residual problems.

Paints viscosity stable and solvent combination of design control coating solution viscosity required.

The status of the coating type OLED device performance

Konica Minolta, solution coating process the lifetime of the OLED lighting device has reached 80% of the level of the vapor deposition process.

UDC hybrid OLED lighting device structure (3 layer solution coated with a layer deposition) red, blue, green, yellow light color of the light emitting efficiency technology evolution.

UDC Hybrid OLED lighting device structure (3 layer solution coated with a layer deposition) red blue green yellow light color component life.

Conclusion

Because the long life of blue light materials is still to be the efforts of the various manufacturers, blue light materials development are recognized as one of the most important key technologies of Konica Minolta’s development of OLED lighting.
