Abstract
A field emission display ( ) having an anode plate ( ) that has phosphor channels ( ). The phosphor channels ( ) are formed by depositing a first layer of photosensitive film ( ) on a substrate ( ). Stripes are patterned into the first layer photosensitive film ( ) using ultraviolet light. A second layer of photosensitive film ( ) is formed on the first layer of photosensitive film ( ). Stripes are patterned into the second layer of photosensitive film ( ) using ultraviolet light. The stripes in the second layer of photosensitive film ( ) are substantially perpendicular to the first layer of photosensitive film ( ). Both layers of photosensitive film are developed to form channel structures. Phosphor is formed in the channel structures to form the phosphor channels ( ). The anode plate ( ) is coupled to a cathode plate ( ) to form the field emission display ( ).
