Sheet pinhole inspection systemThe system evaluates pinholes on a long-length sheet, in high speed and high precision.
|Characteristics||The large image data (about 37 million pixels per second) which multiplies 7,400 pixels by 5,000 lines, is processed at high speed by parallelizing photographing and image signal processing.|
|Inspection items||Detection of pinholes, diameter of a pinhole, area of a pinhole, position coordinate of a pinhole, periodic pitch of pinholes||Inspection target||・Separator for a secondary battery
・Inspection of a hole shape for a perforated film
・Defect detection for a film sheet and a metallic thin film
|Basic specification||・Line scan camera: 3 cameras, high-resolution 7,400 pixels
・Measuring resolution of pinhole diameter: 5um
・Minimum diameter size of detected pinhole: 10 um
・Measuring speed: 60 seconds for a sample size, 100 mm×1200 mm
Inspection system for automotive
This system for automotive LCD modules detects point defects, such as a blight spot pixel and a black spot pixel. The system works up to 10.25-inch display, and detects defects only 50 seconds par a display.
Point defects: bright and black
Bright and black point defects of a LCD module are detected.
・Bright point A bright point (emitted pixel) is viewed in the black display when the sub-pixel of the display always is in ON-state.
・black point A black point (unemitted pixel) is viewed in the white display when the sub-pixel of the display always is in OFF-state.
Black Mura inspection
Black Mura inspection evaluates the luminance uniformity and quantify the luminance gradient to prevent the deterioration of appearance caused by the defect display unevenness or the defects.
