Color analyzer

On April 3, 2024, Konica Minolta (China) Investment Co., Ltd. (hereinafter referred to as' Konica Minolta '), a supplier of optical and display, color measurement technology solutions in Shanghai, announced the release of its new generationColor analyzerCA-527， Can meet the measurement needs of constantly developing new displays such as OLEDs and microLEDs.

new productCA-527 is a device that can measure and adjust the white balance of a monitor*1Gray scale*2And flicker degree*3The optical instrument is suitable for the research and production scenarios of products such as televisions and smartphones.CA-527 is a monitor under the Konica Minolta brandColor analyzerThe latest flagship model in the series, renowned for its fast and precise measurements.

In recent years, with the rapid development of the display industry, researchers and manufacturers urgently need measurement equipment that is faster, more accurate, and applicable to a wider range of brightness.

ButCA-527 hasThe characteristics of low brightness and fast measurement are closely followed by the development trend of new display technology, and its measurement function is constantly updated. This product can meet the evaluation needs of the new generation of high-resolution displays, such as the increasingly popular high dynamic range（HDR OLEDs and microLED displays.

CA-527 monitorColor analyzerthe advantage of

1. Further expand the brightness range that ensures accuracy

traditionalCompared to the CA-VP427A model, the brightness measurement range of CA-527 has been expanded to 0.0001 cd/m2-10,000 cd/m2The lower limit of brightness at low brightness is one-third of the previous level, while the upper limit of brightness at high brightness is twice as high as before.CA-527 can ensure measurement accuracy and repeatability over a larger range, meeting the requirements of the new generation of high-resolution displays (such as OLEDs and microLEDs with higher contrast and wider color gamut) for brightness*5And chromaticity*6More accurate assessment of needs.

2. Measurement speed improvement

With excellent optical design principles,The measurement time of CA-527 is significantly shortened under low brightness, compared to traditional methodsColor analyzerThis is particularly prominent when comparing series. This not only helps with the development of displays, but also shortens the measurement time of display production lines*7.

3. Application function enhancement*8Keeping up with the technological development trend of modern displays

1) The performance of the display's luminous waveform measurement function has significantly improved

traditionalColor analyzercomparison,CA-527 is capable of measuring lower brightness displays at higher sampling frequencies. In recent years, the trend of display technology requires more accurate capture of the waveform of display light emission, such as OLED displays with higher contrast and Micro LED displays using time-division drive.

2) Newly added variable refresh rate (VRR) flicker measurement function

Apart from traditionalColor analyzerprovidedIn addition to the high-performance flicker measurement functions of JEITA, VESA, and FMA methods, a new flicker evaluation index, the Variable Refresh Rate (VRR) flicker measurement function, is also provided. CA-527, with its high-level flicker measurement performance in the industry, not only helps new displays achieve accurate evaluation between image quality improvement and power saving

Main specifications

*Measurement based on Konica Minolta's standard light source (at 6500K color temperature).

*1: White balance refers to the process of adjusting the ratio of red, green, and blue primary colors to accurately reproduce a white image.
*2: Gamma is an indicator that measures the color tone characteristics of a display. Gamma correction makes the brightness and color of black and white half tones appear more natural and smooth.
*3: Flashiness is a parameter that characterizes changes in the brightness of a display. Physically speaking, it is the flicker or fluctuation of light. Flicker also refers to a state that can be perceived by the human eye. Due to the inability of the human eye to observe high-frequency phenomena, flicker can be evaluated by the frequency perception of light through the sensitivity of the human eye.
*4: Triple stimulus color brightness meter (as of March 14, 2024)
*5: Brightness is the intensity per unit area of light emitted by a light source. It is the physical quantity of brightness perceived by the human eye. In the International System of Units, the unit is candela per square meter (cd/m2）.
*6: Chromaticity is the physical quantity of the color of a light source perceived by the human eye. The representative evaluation index is the XYZ color space (CIE 1931) established by the International Commission on Illumination (CIE) in 1931.
*7: Beat time refers to the time required to measure each screen during the production process. Improve measurement ability, reduce beat time, and thus reduce overall costs.
*8: The functions used by customers according to their respective needs
*9: HSI hyperspectral imaging technology is a method of identifying the substance being measured using a camera with a narrow bandwidth in a wide spectral range from visible light to mid infrared. It can be applied to waste recycling, material/impurity identification, food analysis, environmental safety, product surface condition analysis, and other applications.
