A method to make a polished lens-less light emitting diode array entails adhesively mounting light emitting diodes to an etched circuit board. Each diode has a cathode and an anode connected to the diode. A clear polymer is added to the top of each diode and allowed to harden. A black polymer is added to the circuit board to fill the space between the diodes. The black polymer hardens and then is polished to provide a polished, lens-less light emitting diode array with a uniform, level, non-light-scattering surface. |
