Demonstrates effectiveness in preventing bubbles in LCD displays. A de-bubbling autoclave device that is effective in reducing defect rates and improving quality in the manufacturing process.
The liquid crystal display used in the electronic device's display section may develop bubbles during the manufacturing process. These bubbles can be removed after the polarizing film is bonded by creating an appropriate temperature and pressure environment using an electric heating heater and pressurized air. Additionally, the adhesion between the polarizing film and the cell can be enhanced simultaneously, leading to a reduction in defect rates and an improvement in quality during the manufacturing process. The PTU series includes models such as the PTU-305VIII for small displays and research and development, as well as the PTU-507H and PTU-807H, which are equipped with an internal air circulation system. Furthermore, we can also accommodate requests for the design and manufacturing of large custom products with high capacity.
