1. Product Characteristics


<Inside of Screen>	<Braun Tube>

Mask Frame is a component that connects the shadow mask and the inner shield inside a Braun tube. The metal properties are controlled to minimize the magnetic force so that low coercive force and high magnetic permeability can be attained.
Shadow Mask		It selectively transfers the three color electron beams from the electron gun to the screen to enhance clarity.
Inner Shield		It blocks outer magnetic field from interfering to protect the electron beams. It also safeguards the screen from diffused reflection of light and absorbs inner heat.
