Abstract
A display screen includes a backplane, an array of light-emitting diodes electrically integrated with the backplane, the array of light-emitting diodes configured to emit UV light in a first wavelength range, and a plurality of isolation walls formed on the backplane between adjacent light-emitting diodes of the array of light-emitting diodes with the isolation walls spaced apart from the light-emitting diodes and extending above the light-emitting diodes. The plurality of isolation walls include a core of a first material and a coating covering at least a portion of the core extending above the light-emitting diodes. The coating is an opaque second material having transmittance less than 1% of light in the first wavelength range.
