Viewing screen for a display device and method for the fabrication thereof

A method for fabricating a viewing screen for a display device and having a black matrix, the method comprising the steps of:

• providing a glass substrate;
• providing a black surround paste;
• adding to the black surround paste a ductile metal paste in an amount sufficient to realize elastic and non-elastic stress relief of the black matrix;
• adding to the black surround paste lead titanate particles in an amount sufficient to control the propagation of cracks in the black matrix;
• thereafter, depositing the black surround paste on the glass substrate;
• and
• heating the black surround paste and the glass substrate to a temperature and for a duration sufficient to affix the black surround paste to the glass substrate.

A method for fabricating a viewing screen for a display device and having a black matrix, the method comprising the steps of:

• providing a glass substrate;
• providing a black surround paste;
• adding to the black surround paste a ductile metal paste, wherein the black surround paste and the ductile metal paste together define a combined weight, wherein the black surround paste has a weight within a range of 75-85% of the combined weight, and wherein the ductile metal paste has a weight within a range of 15-25% of the combined weight;
• adding to the black surround paste lead titanate particles having a weight, wherein the weight of the lead titanate particles is within a range of 1-5% of the combined weight of the black surround paste and the ductile metal paste;
• thereafter, depositing the black surround paste on the glass substrate;
• and
• heating the black surround paste and the glass substrate to a temperature and for a duration sufficient to affix the black surround paste to the glass substrate.
