Abstract: A non-direct electrical contact orientation ordered nLED light-emitting display device comprises 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 is further provided with an AC drive control module having two ends connected to the upper drive electrode and the lower drive electrode respectively. The nLED grain sheet is formed by a plurality of nLED grains that are arranged in order, so when the nLED grain sheet is disposed between the electrode substrates, a light-emitting layer of each nLED grain is parallel to the electrode substrates and perpendicular to the electric field. At least one of the upper drive electrode and the lower drive electrode is isolated from the nLED grains by an insulating dielectric layer. In presence of the AC drive signal, the nLED grains are lighted up through electromagnetic coupling.

Abstract: A light-emitting display device based on special-shaped nLED grains comprises an upper drive electrode substrate, an upper drive electrode, special-shaped nLED grains, a lower drive electrode and a lower drive electrode substrate that are sequentially arranged from top to bottom, and is further provided with an AC drive control module having two ends connected to the upper drive electrode and the lower electrode respectively. The special-shaped nLED grains are nLED grains each comprising a non-planar luminous layer. The drive electrode is isolated from the nLED grains by insulating dielectric layer. In presence of the AC drive signal, the nLED grains are lighted up through electromagnetic coupling.
