Abstract
A method for fabricating viewing screen (100) includes the steps of: adding to a black surround paste a ductile metal paste, adding to the black surround paste lead titanate particles, depositing the black surround paste on glass substrate (110), and heating the black surround paste and glass substrate (110) to affix the black surround paste to glass substrate (110), thereby forming black matrix (111). The ductile metal paste and lead titanate particles are added in amounts sufficient to realize an extent of cracking in black matrix (111) upon repeated heating to a temperature within a range of 450-600° C. that is significantly less than that exhibited by an unimproved black matrix, which is made only from the material of the black surround paste.
