Abstract:
A flat panel display apparatus comprising:a) a display panel on the front face of said display apparatus, said display panel having an inner surface with a target area for receiving a cathodoluminescent screen, said display panel being composed of a glass having a predetermined coefficient of thermal contraction; andb) a backplane on the rear of said display apparatus, said backplane having an inner surface reflective to electrons, said backplane being composed of a glass having a predetermined coefficient of thermal contraction; andc) a spacing component secured to the inner surfaces of said display panel and said backplane by devitrified solder glass, said spacing component forming a sealed envelope within said apparatus, said spacing component having a net coefficient of thermal contraction which is lower than said predetermined coefficients of thermal contraction of said display panel and said backplane such that after devitrification of said solder glass at an elevated temperature to affix said spacing component to said display panel and said backplane, and subsequent cool-down, said display panel and said backplane are placed under predetermined significant compression.
