Panel Display

mini LED display as a kind of LED technology, its products have begun to be applied to super large screen high-definition display, such as monitoring and command, high-definition studio, high-end theater, medical diagnosis, advertising display, conference and exhibition, office display, virtual reality and other commercial fields.

Requirements: Measure the thickness of graphite under the film as shown in the above figure, first circle the measured area, the thickness of the ink on the film is measured, try to choose the ink near the graphite for measurement, because the measurement object is opaque, in order to ensure accuracy, the use of a dual-axis beam platform dual-axis beam platform, is the use of two side heads, through the way of the center, is the spot of the two probes overlap, Thus, the accuracy of the measured area is guaranteed. The regional accuracy of 4 products can be obtained from the above figure.

Scanning and measuring the height of 4 bottles of glue Liquid level height measurement First put the 4 bottles of glue to be measured neatly on the moving device, fix the 90-degree lens position, and use the height of the ceramic measuring block as a reference line. Liquid level height measurement This test adopts the full range controller of Vertical Technology H4UC, lens adopts D35A7R16 to scan the height of the glue level of the sample, lens dynamic scanning test, frequency 1000HZ to sweep the glue level height, non-contact liquid level measurement, non-destructive sample.

Detection requirements: To measure whether the glue in the sample gap is broken, the vertical instrument spectral confocal controller is used in this test, and the sensor D35A30R4 is used. The product is placed horizontally on the scanning platform of the profiler, and the product surface is scanned by the profiler. Apply glue to the area to be detected (as shown above), set the relevant parameters on the contour scan, and scan (as shown below), and then the data we want will appear. Lii Technology is a company specializing in the production and development of spectral confocal displacement sensors, laser displacement sensors, white light interferometers, film thickness meters, products are widely used in 3C, semiconductor aerospace and other high-precision detection. ...
