GETTER CONTAINER FOR CRT

摘要

The container for preventing the evaporation of a getter (13) towards the shadow mask and improving the removing efficiency of the residual getter gas has an opened hole (13) on the side body. The getter filled in the container is evaporated and diffused towards the side direction so that the shadow mask is not coated by the getter. It also increases the diffusion efficiency of the getter because the opened hole size is expanded from inside to outside.
