1. A non-direct electrical contact orientation ordered nLED light-emitting display device, comprising an upper drive electrode substrate, an upper drive electrode, an nLED grain sheet, a lower drive electrode and a lower drive electrode substrate that are sequentially arranged from top to bottom, and being further provided with an AC drive control module having two ends connected to the upper drive electrode and the lower drive electrode respectively, wherein the nLED grain sheet is formed by a plurality of nLED grains that are arranged in order;
the nLED grain sheet is disposed between the electrode substrates, a light-emitting layer of each nLED grain of the plurality of nLED grains is parallel to the electrode substrates and perpendicular to a electric field;
and at least one of the upper drive electrode and the lower drive electrode is isolated from the plurality of nLED grains by an insulating dielectric layer.
