Display Color Analyzer CA-527
The Konica Minolta CA-527, the newest addition to the industry-standard display color analyzer series, delivers improved performance with a wide luminance and chromaticity measurement range, high-speed measurement capabilities, and improved Waveform measurement. Along with its new Variable Refresh Rate (VRR) flicker measurement feature, the Konica Minolta display color analyzer CA-527 is well-equipped to address the measurement requirements of the latest OLED and micro-LED display technologies.
Wide Dynamic Range Luminance and Chromaticity Measurement
The Display Color Analyzer CA-527 provides precise measurements for luminance ranging from 0.0001 to 10,000 cd/m² and chromaticity from 0.001 to 10,000 cd/m². It enhances measurement accuracy and repeatability, particularly beneficial for evaluating the latest OLED and micro-LED display technologies with superior contrast ratios and wider color gamuts.

High Speed Measurement at Low Luminance
The new optical design used in the Display Color Analyzer CA-527 enables much quicker measurement speeds, especially in low luminance conditions. Achieving a measurement speed of 1 second at a luminance level of 0.0001 cd/m2 in “Auto” mode, the Display Color Analyzer CA-527 enables faster and more efficient measurements, minimizing takt time in display production and research and development.

Improved “Waveform” Measurement
The Display Color Analyzer CA-527 offers the capability to measure lower-luminance regions with a higher sampling rate. This improved feature enables it to capture the emission waveforms of displays more accurately, especially with the advancements in display technologies like OLED screens moving towards higher contrast ratios or the latest micro-LED displays using dynamic drive systems.
Variable Refresh Rate (VRR) Flicker Measurement
The Display Color Analyzer CA-527 provides the latest Variable Refresh Rate (VRR) flicker measurement functionality alongside other techniques such as JEITA, VESA, and Flicker Modulation Amplitude (FMA). This distinctive blend of flicker measurement methods is well-suited for evaluating the quality of displays that aspire to achieve advanced video quality and energy-efficient capabilities or professionals looking to analyze displays using various flicker measurement techniques.

*1: Measured under Konica Minolta’s standard light source (6,500K).
*2: The luminance for monochrome is measured when reading of luminance for white is 100 cd/m2.
*3: Temperature 23°C/±2°C, relative humidity 40%±10%
*4: In NTSC synchronization mode using USB with one probe. Measured using a Konica Minolta-designated PC (with PC and probe directly connected, using the supplied measurement software).
*5: Reading fluctuation (compared to reference reading at 23°C, 40% RH): Luminance: ±2% for white; Chromaticity (at 100 cd/m2): ±0.002 for white, ±0.003 for monochrome.
*6: “Flicker (CA-310 Mode)” and “XYZ (Wide Frequency Mode)” are mode names for PC Software CA-S40.
*7: Measured under Konica Minolta’s standard light source (constant light). If the luminance momentarily greatly exceeds the upper limit, such as with a PWM light source with a small duty cycle, luminancses below the upper limit may be shown as too high.
