Konica Minolta launches CA-410, a colour analyser for measuring a wide range of displays including OLED displays

Summary

Konica Minolta, Inc. (Konica Minolta) has launched the CA-410, a colour analyser for measuring ever-evolving displays such as OLED displays.

The CA-410 is an optical measuring device used for inspection and adjustment of white balance[1] and gamma[2] 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.

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 colour reproduction, such as HDR displays. As a result, manufacturers of such displays require a colour analyser with a wider measurement range, from extremely low to high luminance.

With its new sensor circuits, the CA-410 achieves an accuracy-guaranteed luminance range from 0.001 to 5,000 cd/m2, 25 times wider than the previous model. This increased measurement range will help manufacturers to control and improve the quality of high-resolution displays, enabling smartphones and TVs to show higher-quality images and videos.

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 speed.[3] 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.

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.

Seeking to capture a greater share for light-measuring products

The Color Analyzer series which the company has been offering and evolving over the past 35 years are now recognised as the de-facto global standard in the area of quality control of TVs and are used by the world’s major display manufacturers for a variety of purposes, including the inspection of smartphone and other OLED displays.

Konica Minolta seeks to capture a greater share for light-measuring products by capitalising on the growing demand for OLED displays and other market changes, and for colour-measuring products by developing new product applications for the automobile, food and building-material industries.

[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.
