Power supply for driving liquid crystal cells
This is a power supply unit that outputs (+) side pulses and (−) side pulses at the selected frequency. The voltage values of the (+) and (−) pulses, as well as the offset voltage on the low voltage side, can also be set. There are outputs for CH1 and CH2, which can be independently configured and driven.

Company information
Since our founding in 1972, we have supported engineers and researchers involved in displays. We manufacture and sell various glass substrates and world-standard EHC cells both domestically and internationally, which are the core of our business. In recent years, there has been a growing demand for diverse metal deposition substrates and high-resolution patterned glass substrates. As peripheral equipment, we provide custom small LCD panel assembly systems, wet process equipment, and measurement and inspection devices for organic EL and solar cells, either as dedicated systems or including simple jigs and other components.
