Product Introduction
Provide high-precision measurement for white balance adjustment of LCD displays with LED backlighting, greatly improving work efficiency
Using our existing color analyzer CA-210 to adjust the white balance of an LCD display with LED backlight, the measured chromaticity error will be within?? 2xy=0.010, if using the new model CA-310, the measurement error under the same conditions can be controlled within?? 2xy=0.003 or so, the color display is more natural and the picture feels more realistic.
Product Features
The measurement error caused by the deviation of LED emission radiation curve can be reduced to less than 1/3 of traditional models
Even the emission radiation curves of LED backlights from the same batch often differ, with a shift of about 10nm at the peak. If a traditional color analyzer is used to measure and adjust the white balance of this characteristic screen, the error caused by xy chromaticity may be close to 0.010. But if CA-310 is used, the chromaticity error under the same conditions will be reduced to about 0.003, which is about one-third of the original, greatly improving the measurement accuracy and stability.
Deviation phenomenon of LED backlight radiation curve
Measurement error of LCD backlight
*Using CA-310 to measure LED backlit displays with different peak values, after user calibration, screens with different offsets result in different measurement errors (differences from true values)
Even at extremely low brightness of 0.005cd/m2, high-speed measurement can be ensured
The application of signal-to-noise reduction technology enables a measurement speed of 4 times per second even at low brightness of 0.005cd/m2. This is very attractive for manufacturers who pursue a 100000:1 high contrast ratio (the direct effect of high contrast display is a more realistic and clear picture). In addition, when the brightness is greater than 2cd/m2, the measurement speed can even reach 20 times per second.
*When the maximum brightness is 500cd/m2
Probe Type Table
This table contains most common lighting modes for various display devices.
*Some displays with specific lighting modes cannot be measured. You can contact the nearest Konica Minolta representative office for more information.
For example, the following display devices cannot be measured using this model of instrument:
A display that uses PWM or other methods to control brightness
Display with intermittent backlight emission
Display with black every frame
