The traditional screen in industrial quality inspection has many limitations, one of which is the lack of color reproduction affects the detection accuracy. Ordinary LCD screen NTSC color gamut only covers about 70% of the human visible spectrum, resulting in some of the red and blue wavelength signal distortion, color gamut coverage limitations. In the semiconductor wafer surface defect detection, the traditional screen can not accurately present the 0.1μm level of fine scratches in the metal reflection difference. In addition, there are dynamic contrast defects, low brightness areas (such as shadows) and high light areas of the color ratio is less than 1:500, it is difficult to distinguish some color defects. Therefore wide color gamut screen technology is necessary.
So what are the advantages of wide color gamut screen technology?
1. Accurate color expression
Wide color gamut screen using DCI-P3 1.2 or Adobe RGB 98 color gamut standard, color coverage increased to more than 2 times the traditional screen. In the optical lens coating inspection, it can distinguish the difference in reflectivity within the 200nm wavelength range.
2.10bit color depth processing
Supports 1024 levels of grayscale output per channel, which improves the color level resolution to 4 times of the traditional 8bit screen. In circuit board solder paste printing inspection, it can clearly present the tiny difference of 0.5K color difference between 0.02mm wide lines.
3. Hardware-level calibration system
Integrated XYZ color sensor real-time feedback, combined with LUT algorithm correction, in the LED light source color temperature fluctuations ± 2000K range to maintain ΔE < 2 color consistency.
4.Application Scenarios of Wide Color Gamut Screen
It can be applied to precision optical components. By enhancing the UV band response (400-450nm), together with the multi-spectral imaging technology, it successfully identifies 23% of the nanoscale scratch defects missed by traditional equipment. On textile display equipment, sRGB and Pantone dedicated color calibration modes are used, combined with AI algorithm to automatically compare CMYK value deviation, and real-time deviation is realized on 400㎡ continuous production line. In food packaging printing can be configured with ambient light sensor linkage to adjust the screen color temperature, with HDR display technology to compensate for reflective interference.
