-
How do I contact Sumation?
You can contact Sumation by phone, in writing or by email. Please see the "contact us" page for more information.
-
How do I obtain samples of material for evaluation?
Small samples of R&D materials can be obtained for evaluation by contacting our sales staff at info@sumation.co.jp. A Non-Disclosure Agreement (NDA) must be signed before materials can be provided. Please click here to view Sumation's standard NDA.
-
What is the lead time on samples?
If materials are in stock they can be provided in approximately 2 weeks. Actual delivery times are dependent on shipping route and custom procedures. If materials are not in inventory and have to made, then typical lead times are 6-8 weeks.
-
Does Sumation provide materials for passive matrix and active matrix displays?
Yes, Sumation provides different materials optimised for these applications.
-
How much do Sumation Light Emitting Polymers cost?
Prices depend on material type, ink concentration and volume ordered, please contact us for a quotation.
-
What lifetime and efficiencies can I expect using Sumation materials?
Lifetime and efficiency can depend on how materials are processed and the exact device architecture employed. Sumation technical staff can advise on how to get the best performance from Sumation LEP materials. If similar process conditions and device designs are used to those at Sumation, results similar to those quoted on this website will be obtained.
-
Are lifetimes and efficiencies quoted by Sumation for ink jet printed devices or for spin processed devices?
The performance data for Sumation materials are typically obtained from test cells made by spin processing. Ink jet print lifetimes can differ from the spin processed results. Ink jet print lifetimes can be shorter or longer depending on the ink formulation and print process conditions used. Please contact Sumation for additional information on optimum ink selection and processing details.
-
Does Sumation have materials available for lighting, OSC or PV applications?
