Shadow mask frame structure with long-sides having higher mechanical
strength
摘要:
In a color cathode ray tube apparatus, a shadow mask is fixed on a frame with a predetermined tension for cancelling a thermal expansion of the shadow mask during normal operation of the color cathode ray tube apparatus. The mechanical strength of the longer sides on the frame is higher than that of the shorter sides of the frame by fixing reinforcing plates or ribs on the longer sides in order that the tension of the shadow mask not become uneven.
