NEXTEYE Registers 11th Core Patent, Enhancing Optical Inspection Efficiency

with Innovative Film Holding Technology

South Korea’s leading machine vision technology company, NEXTEYE, announced today (July 8, 2025) that its independently developed technology — the "Film Holder for Inspection Devices" — has officially been granted a patent, marking yet another breakthrough in overcoming long-standing technical barriers.

This newly granted patent marks NEXTEYE’s 11th core achievement, following its seven domestic patents — including technologies for polarizing film inspection devices, LED modules, backlight unit inspection systems, and foreign substance detection in instant rice containers — and three overseas patents such as those related to LCD panel inspection systems.

It represents a significant milestone as it not only raises the bar in the field of high-precision optical inspection, but also further solidifies NEXTEYE’s technological leadership and dominance over key industry innovations.

Overcoming Technical Barriers

Conventional film-holding methods have long faced two major technical limitations due to the use of opaque suction plates. First, the blocking of backlight illumination leads to image distortion; Second, the exposure of suction holes in the imaging field introduces a high risk of false detection. As a result, these limitations have continuously hindered overall inspection accuracy in optical systems.

This newly patented technology achieves two simultaneous breakthroughs through an innovative structural design — all while maintaining the suction functionality:

1. Hidden Airflow System: By placing the suction holes on the sides, an internal air channel is formed, allowing the film to adhere closely to the base. This effectively suppresses curling and deformation of the film during inspection.
2. Fully Transparent Glass Base: Designed to allow unimpeded backlight transmission, this structure eliminates visual interference, enabling high-precision inspection of transparent films and glass substrates.

The innovative value of the "Film Holder for Inspection Devices" extends far beyond conventional inspection settings, offering broad applicability across diverse high-tech fields.
This technology holds strong potential for deployment in industries requiring ultra-precise optical inspection, such as display panels, semiconductors, and biosensors.
It not only enhances inspection accuracy, but is also expected to deliver significant improvements in efficiency and cost-effectiveness by reducing inspection time and operational overhead.

“This is not merely a hardware upgrade,” emphasized Vice President Yang Ki-il of the Vision Inspection Division.

“It represents a core solution to enhancing optical inspection efficiency in machine vision — and more than that, a fundamental evolution in the principles of optical inspection itself.”

He added,
“While the industry continues to explore ‘how to see,’ we have already moved a step further — solving the challenge of ‘how to see with precision.’
This patent will accelerate the adoption of machine vision technologies across a wide range of emerging fields and will further strengthen NEXTEYE’s competitive edge in the machine vision industry.”
