Application Case Study of Hongchuan Technology LTC Series Spectral Confocal Sensors in UTG Flexible Screen Thickness Measurement
1. Industry Background and Core Pain Points in UTG Thickness Measurement Ultra-Thin Glass (UTG) is the core substrate for foldable screen terminals, with thickness typically controlled between 20-100μm (some high-end models can be below 10μm), combining flexibility, mechanical strength, and optical transparency. The uniformity of UTG thickness directly determines the bending life of the foldable … Read more
