Konica Minolta Launches the CA-527, a Next-generation Display Color Analyzer Offering Industry-leading Ultra-low Luminance Measurement and High Speed

Quickly Meeting the Needs of Development and Production Sites of Evolving Next-generation Displays

ca-527Ramsey, New Jersey (4/1/2024) – Konica Minolta Sensing Americas is pleased to introduce the launch of the CA-527, a color analyzer that meets the needs for evaluating ever-evolving cutting-edge displays, such as OLEDs and microLEDs.

The CA-527 is an optical measuring device used for inspection and adjustment of white balance,*1 gamma,*2 and flicker*3 at sites that develop and produce displays for TVs and smartphones, among others. This is the latest flagship model of the Display Color Analyzer series, which is reputed for its high-speed, accurate measurement.

The CA-527 offers industry-leading*4 low luminance measurement and high speed. The application function has also been enhanced in line with the technology trend of cutting-edge displays. The product meets the latest evaluation needs of high-resolution next-generation displays, such as increasingly higher-dynamic-range (HDR) OLEDs and microLED displays.


Value Provided by the CA-527 Display Color Analyzer

  1. Further expansion of the accuracy-guaranteed luminance range

Compared to the conventional CA-VP427A model, the measurement dynamic range has been expanded to cover from 0.0001 cd/m2, which is one third the brightness in low luminance, up to 10,000 cd/m2, which is twice the brightness in high luminance. The CA-527 guarantees the measurement accuracy and repeated measurement performance over a wider range, meeting the need for more accurate evaluation of luminance*5 and chromaticity*6 of high-resolution next-generation displays, such as OLEDs and microLEDs, with their ever-higher contrast ratio and wider color gamut.

  1. Increase in measurement speed

Thanks to the state-of-the-art optical design, the CA-527 significantly reduces the measurement time at low luminance in particular compared to the conventional Color Analyzer series. This is not only useful for R&D on displays but also reduces the takt time*7 during the manufacture of displays.

  1. Enhancement of the application function*8 that meets the technology trend of cutting-edge displays

1) Significant performance improvement of the display light-emitting waveform measurement function

Compared to the conventional Color Analyzer series, the CA-527 can conduct measurement in the lower luminance ranges at higher sampling frequencies. This can more accurately determine the display light-emitting waveforms, which are becoming increasingly complex, in line with the recent trend of display development technology, including OLED displays, toward higher contrast ratio, and cutting-edge microLED displays, which use the time-sharing drive method.

2) New implementation of the variable refresh rate (VRR) flicker measurement function

The function to measure the flicker that could be caused by the variable refresh rate (VRR), which is becoming a standard feature of cutting-edge displays, has been newly implemented in addition to the high-performance flicker measurement function, including the JEITA method offered by the conventional Color Analyzer series. The CA-527 aims to become the new de facto standard with industry-leading*4 flicker measurement performance for evaluating the quality of the latest displays which offer higher video quality and consume less power.

*1:White balance is the process of adjusting the light intensity ratio of light in the three primary colors – red, green, and blue – for accurate reproduction of white.

*2:Gamma is a measure of tonal response. Gamma correction makes the brightness and color of the black and white halftone appear more natural and smooth to the eye.

*3:Flicker is a visible change in brightness on a display. Physically, it is the blinking or fluctuation of light. Flicker also refers to a state that can be perceived by the human eye. Because the human eye cannot observe high-frequency phenomena, flicker may be evaluated by taking into account the frequency characteristics of sensitivity.

*4:As a luminance colorimeter of the photoelectric tristimulus colorimetry type as of March 14, 2024

*5:Luminance is the quantified brightness per unit area of light emitted from the light source. It is the psychophysical quantity of brightness perceived by individuals. In the International System of Units, the unit is candela per square meter (cd/m2).

*6:Chromaticity is the quantified color of the light source perceived by individuals. The most typical evaluation index is the XYZ color space (CIE 1931) defined by the International Commission on Illumination (CIE) in 1931.

*7:Takt time is the operating time required until one product is manufactured in the production process. Reducing the takt time improves production capacity, and thus generally reduces cost.

*8:The application function is used by users depending on the purpose.

*9:HSI is a method that uses a camera with narrow bandwidth over a wide spectral range from the visible to mid-infrared wavelength region to identify substances in an area. It is expected to be used for applications such as recycling, material/resource identification, food analysis, environmental safety, product surface condition analysis, etc.
