How is the imaging device applied to the field of LCD screens?

. Inspection in the field of LCD display screen production and manufacturing

Nowadays, LCD screens are often seen, such as on computers and televisions. Mechanical devices such as LED/VFD are gradually being replaced by LCD screens on displays. In the production process of LCD screens, inspection is crucial for product quality control. At present, the inspection of defects in LCD screens is mainly based on manual service, which relies on human visual impact to distinguish the quality of the product. This will result in a high level of subjective discrimination, promoting the identification of high-precision professional ultrasound that is not precise enough, with significant changes and differences. This leads to several difficulties for enterprises:

1. In terms of manual service inspection, there are high requirements for the staff, and the training and learning time can last up to two months.

2. The high turnover rate of employees will continue to pose a threat to their vision.

3. The low accuracy of manual service inspection leads to a high number of customer complaints.

4. Labor costs are becoming increasingly prominent, and enterprise costs are increasing.

. Research status

With the rapid development of information technology, fluorescence penetration assembly line detection machine vision technology and electronic technology, a new non-destructive testing technology has emerged this morning: "visual inspection technology". Visual inspection technology is based on images as media, processing image information through specific methods to obtain reasonable information within it.

Machine equipment visual inspection integrates the technical aspects of mobile bridge coordinate measurement machine vision technology and the basic concepts of optoelectronic device inspection, and then reconstructs it into a new non-destructive testing technology. It is based on electronic optics technology, combined with electronic information technology, image processing technology, electronic information technology and other technological innovations today, resulting in the integrated detection instrument of light, electricity, and computer - the imaging instrument.
