As a highly innovative technological achievement, organic electroluminescent flexible transparent display screens are gradually changing our understanding and application of display devices.

Compared with traditional display screens, it not only has inherent advantages such as self-luminescence, high contrast, and wide viewing angle, but its unique flexibility and transparency have brought revolutionary breakthroughs to display technology. This flexibility enables the display screen to adapt to various irregular shapes of device surfaces, providing unlimited possibilities for the design of emerging products such as wearable devices and curved displays; while transparency further expands its application scenarios, such as in car windshield displays, building curtain wall displays, and augmented reality (AR) / virtual reality (VR) devices, greatly enriching people's visual experience and interaction methods.

[0003] However, in the manufacturing process of organic electroluminescent flexible transparent display screens, the feeding link has become a key factor restricting product quality and production efficiency. Due to the flexibility and transparency of display screen materials, it faces many technical difficulties in the feeding process. The fault detection and processing capabilities of feeding equipment are crucial to ensuring production continuity and product quality. Traditional feeding equipment often lacks a complete fault detection mechanism, and it is difficult to timely discover and accurately judge problems such as motor failure, blockage during material transportation, and material surface defects.
