LG Electronics developed a perfect flat color display tube which was named "FLATRON" . This tube provides ergonomic performances with perfectly flat face and innovative manufacturing process. Foil transfer is a new technology for manufacturing screen layer for Flatron. Its main features include several properties of film, releasing agent, adhesive, aluminum layer, holes after bake-out and foil transfer process. It will be used innovative and cost oriented process for FLATRON for in CRT mass production..

The vibration of a mask degrades the color purity in CRT. In order to reduce the vibration. a damping wire is put into contact with the mask in the Flatron. We analyzed the vibration of the mask considering the damping wire using FEM. The natural frequencies and mode shapes of the mask are calculated by modal analysis. And those are compared with the measured results to confirm our finite element model. The modal analysis of the wire is also performed to investigate resonance with the mask. Finally, the transient dynamic analysis of the mask contacting with the wire is performed. The vibration of the mask is measured to confirm our analysis, and the results are in good agreement with the analysis.

We developed the tension mask of which thickness increased from 25 urn to 50 urn to reduce the mask cost and improve the vibration property. First of all, the limitation by which rail structure can support is calculated and the optimal thickness of mask is determined. To prevent the reduction of brightness and brightness uniformity, the dimensions of mask was reassigned. As a result, the increase of mask thickness brought about a reduction in cost and improvement of howling property which had been a weak point of flat CRTs.
