Organic materials are rapidly being developed for a wide range of markets from commercial electronic displays (TVs, PCs, cell phones, tablets), to home, commercial, vehicle and street lighting. These materials are extremely thin offering much reduced product thickness and weight, require much less power (extended battery operation), and are relatively easy to manufacture. They can be used for flexible electronic devices and even for transparent displays (head-up automotive display panels). These materials produce bright displays with high contrast ratios making them useful for outdoors applications.
New technologies, including OLED, are being developed to replace the incandescent light bulb by more efficient and longer lasting light sources, allowing more varied control of room lighting and colors, with the new technologies extending to automotive and street lighting applications.
Solartron Analytical provides the following test systems for the characterization of organic electronic materials:
- The ModuLab XM MTS Test System provides complete time domain and AC device characterization using a wide range of “Plug and Play
- The Model 1260A Impedance Gain Phase Analyzer is widely referenced in publications and is able to test capacitance / C-V / impedance / Mott-Schottky from 10 µHz to 32 MHz (over 12 decades of frequency), enabling full characterization of dielectric materials.
- The Model 1296A Dielectric Interface System extends the impedance range of the 1260A to over 100 TOhm for testing ceramic insulators and dielectrics in addition to providing greater magnitude and phase accuracy by use of sample/reference techniques, reducing errors due to cables.
- Temperature control options including Cryostats and Furnaces are available with all of the above measurement systems that provide automatic PC control of the sample temperature and allow complete material characterization
Glass and polymer dielectric materials used as display substrates and touch panels can also be tested using the above equipment
