The invention relates to a non-direct electrical contact orientation ordered nLED light-emitting
display device. The device comprises in order from top to bottom: an upper driving
electrode substrate,an upper driving
electrode, a nano LED
crystal grain sheet, a lower driving
electrode and a lower driving electrode substrate. The device further comprises an alternating-current driving control module, the two ends of the alternating-current driving control module are respectively connected with the upper driving electrode and the lower driving electrode, the nano LED
crystal grain sheet is formed by orderly arranging a plurality of nano LED
crystal grains, so that when the nano LED crystal grain sheet is placed between the electrode substrates, and the light-emitting layer of each nano LEDcrystal grain is parallel to the electrode substrates and is perpendicular to the direction of an
electric field; and at least one of the upper driving electrode and the lower driving electrode is isolated from the nano LED crystal grains through an insulating
dielectric layer, and the nano LED crystal grains are lightened through
electromagnetic coupling under an alternating driving
signal. According to the invention, an indirect electrical
contact method is adopted to achieve ordered nLED light-emitting display, a huge transfer process of micron-scale and nano-scale LEDs can be omitted, andthe process cost is effectively reduced.
