Electronic device and method of making thereof

There is provided a method of forming a light source, the method comprising providing a backplane comprising a backplane substrate and a semiconductor particle formed separately from the backplane substrate and then fixed upon the backplane substrate at a predetermined position. The semiconductor particle can be planarized to remove a portion of the semiconductor particle and to expose at a cross-section of the semiconductor particle a planar surface. Moreover, the backplane may comprise a controllable gated electronic component on or directly beneath the planar surface. The controllable gated electronic component may be configured to control an LED emitter. The method further comprises providing the LED emitter comprising one or more LEDs electrically connected to the backplane such that at least one of the LEDs is electrically connected to the controllable gated electronic component.
