    摘要: In an array of LEDs coupled between a transparent substrate and an electrode, a light emitting surface of each LED is in electrical contact with a region of acicular ITO. By contacting the light emitting surface of the die, the acicular ITO also provides light scattering. The contact regions are interconnected to form the array. The acicular ITO acts as a ballast resistance for each die and the resistance can be trimmed for more uniform current among the LEDs. Because each LED is individually ballasted, the LEDs in an array can be driven in any pattern or all simultaneously at a consistent brightness.
