DC drive high-precision lifetime testing device for 32CH to 128CH. High-precision current output, element voltage measurement, and brightness measurement using PD.
1. High-precision current output. Correction through current value monitoring is unnecessary. 2. High-precision voltage measurement. High-precision measurement is possible to detect voltage fluctuations caused by a 1°C temperature change in the element. 3. Four-terminal connection. Voltage drops due to connection cables to the DUT are compensated. (For example, a voltage drop of 1Ω for a round trip at 10mA can result in a significant error factor of 10mV.) 4. Noise countermeasures enabling high-precision measurement. By synchronizing the power supply for photometry, suppression of noise from indoor fluorescent light flicker and AC power is achieved. 5. Fully automated lifetime testing is possible with control software for Windows. Measurement values for all 128 channels are collected at 2-second intervals, and the measurement interval can be set in five stages from 2 seconds to 24 hours. (Example: the first 5 minutes at 2-second intervals, the next hour at 30-second intervals, the next 12 hours at 5-minute intervals, the next 24 hours at 10-minute intervals, followed by 60-minute intervals.)
Inquire About This Product
basic information
The Model2805B is a high-precision lifetime testing device specialized for DC drive, with a range of 32CH to 128. It provides constant current output with high resolution and stability, allowing for highly accurate measurement of the voltage of OLED elements. It has a built-in photodiode amplifier, enabling simultaneous measurement of luminous intensity from a photodiode placed close to the OLED. The Model2805B can be controlled from a Windows PC using dedicated software, allowing for fully automated lifetime testing at user-specified time intervals.

Company information
San Water Co., Ltd. designs all of its current products in-house, based on high-speed, high-precision analog circuit technology cultivated over a quarter of a century of IC tester design and manufacturing, without relying on external contracting, outsourcing design, ODM, or OEM. Additionally, we do not adopt a distributor system and sell everything directly. As a result, we can directly reflect customer requirements in product development and improvements.
