Abstract
A tension mask frame assembly for use in a cathode ray tube is provided. The tension mask frame assembly includes a substantially rectangular mask support frame, having a first coefficient of thermal expansion. The frame is formed of a pair of opposing long sides being joined to a pair of opposing short sides wherein one of these pairs has an attachment zone. The tension mask, having a second coefficient of thermal expansion, is supported by the frame at the attachment zones along the opposing sides. The attachment zones are formed of a material having a coefficient of thermal expansion which is approximately the same as the second coefficient of thermal expansion in order to be matched with the tension mask.
