Konica Minolta, Inc. (Konica Minolta) announced that it will launch the CA-410, a color analyzer for measuring ever-evolving displays such as OLED displays, on November 15, 2017.
The CA-410 is an optical measuring device used for inspection and adjustment of white balance1 and gamma2 at factories producing TVs, smartphone displays, etc. Designed as the successor of the CA-310, which is reputed for its rapid, accurate measurement, the CA-410 similarly offers high-speed, high-accuracy measurement of higher-dynamic-range (HDR) displays, including OLED displays.
CA-410 Provides New Values
1. Accuracy-Guaranteed Luminance Measurement Range 25 Times Wider Than the Previous Model for Higher-Quality HDR Displays
Recently, demands for higher-quality images and video have been growing among smartphone users, due partly to dramatic increases in communication speed. In response, manufacturers are accelerating the development of higher-resolution displays with improved contrast ratio and color reproduction, such as HDR displays. As a result, manufacturers of such displays require a color analyzer with a wider measurement range, from extremely low to high luminance.
2. Faster Measurement Speeds to Improve Productivity
The CA-410 can measure extremely low luminance levels of just 0.001 cd/m2 in one second, fast enough for integration into manufacturing processes. In addition, total measurement time is reduced by 30% compared to the previous model by improving sensor capabilities and CPU calculation speed3. This allows the CA-410 to contribute to higher productivity at factories producing high-resolution displays, such as by reducing the gamma correction process time.
3. Easy Integration into Automated Processes for the Digital Manufacturing Age
In anticipation of the needs of the digital manufacturing age, the CA-410 is designed as a sensor that can be easily integrated into automated manufacturing processes. It allows measurements to be started and performed without manual tasks, and the probe can be connected directly to the computer to save space.

1 White balance is the process of adjusting the light intensity ratio of light in the three primary colours – red, green and blue – for accurate reproduction of white.
2 Gamma is a measure of tonal response. Gamma correction makes the brightness and colour of the black and white halftone appear more natural and smooth to the eye.
3 Based on gamma measurement simulation compared to CA-310 under Konica Minolta’s test conditions (for 64 measurements). It excludes display startup time and wait time.
4 The values are when using a normal CA-P427 probe.
5 Measured under Konica Minolta’s standard light source (6500K).
6 Measured under Konica Minolta’s standard light source (6500K).
