    摘要: A simplified means for supporting the components of a high resolution CRT assembly without utilizing a separate rigid metal frame is disclosed. The components including the CRT, coils and coil positioners are supported by the magnetic shield thereby eliminating the necessity of the intermediate rigid frame without impairing the precision and performance of the CRT function.
