    Available measurement methods and the settings that must be made are explained below. <Measurement by Konica Minolta’s Calibration Standard> With this method, measurement is performed using Konica Minolta’s calibration standard without calibration. Even if you are setting the target color to the memory channel CH00, measurement must be performed as ex- plained below.
  • Page 49 <Measurement by Analyzer Mode> With this method, the measured colors are expressed in emission intensity of each R, B and G monochromatic light based on the display’s analyzer mode RGB emission characteristic (which is input to the instrument’s memory channel) and the target color (W). Since the target color is also set, the analog display section can show the deviation of the measured values from the target color.

  • Page 53: User Calibration

    ● When this instrument is used for the first time since shipment from the factory, measurement will be performed based on the calibration carried out by the Konica Minolta’s calibration standard. This applies to all the memory channels. Once user calibration is performed, the following correction will be made when measurement is performed using the obtained correction factor.

    5. Optical System of Measuring Probe The optical system consists of an objective lens and optical fiber. Among the lights emitted from the LCD under measurement, only the lights that are emitted at within ±2.5 degrees and LED Flicker Measuring ø10 Probe(CA-PS32/35) : ±5 (LED Universal Measuring ø10 Probe(CA-PSU32/35) degrees) perpendicular to the LCD are guided by the objective lens to the fiber.

    Two kinds of quantifying measurement methods are available: contrast method and JEITA method. With the CA-310 with LED Flicker Measuring ø27 Probe(CA-P32/35) or LED Flicker Measuring ø10 Probe(CA-PS32/ 35) alone, the contrast method is possible. Use of the software supplied with the instrument also allows JEITA method.
  • Page 99 (2) JEITA Method With the contrast method, the amount of flicker does not depend on its frequency, and is calculated based on the AC and DC components of the measured luminance. However, human sensitivity to flickering starts to drop gradually at about 30 Hz, and when the frequency exceeds 60 Hz, it is no longer possible for humans to sense it.
  • Page 100 As shown in Fig. 4, when two or more frequency components (P0, Px1, Px2) exist, the maximum value among all the frequency components (Px1, Px2 in the case of Fig. 4) except for P0, that is the component of frequency 0, will be set as Px.

  • Page 102 LED Flicker Measuring ø27 Probe(CA-P32/35) or LED Flicker Measuring ø10 Probe(CA-PS32/35) the CA-310 is limited to be used only for measuring displays whose intensity does not vary in a frame scanning period as shown in Fig. 5-3. So inaccurate measurement data is sometimes obtained for CRT or PDP with the CA-P32/35 or CA-PS32/35.
