DETAILED DESCRIPTION - The system comprises ink jet printer, light emitting device and conductive ink nanosilver. The ink jet printer comprises input control system, output control system, ink supply device, micropiezoelectric spray head and infrared solidifying device or photon sintering solidifying device. The input control system processes the electronic graphics file into the data signal identified by the output control system of the inkjet printer. The output control system is used for receiving the data signal and supplying the data to ink supply device, micropiezoelectric spray head, and infrared solidifying device or photon sintering solidifying device corresponding to the specific ink supply control work instruction, ink jet work instruction and curing work instruction. The ink supply device is used for analyzing the ink supply control work instruction, obtaining the image image data quantity, and providing constant voltage and constant current and nano-silver of the conductive ink to the micropiezoelectric spray head. The micropiezoelectric spray head is used for analyzing the ink jet working instruction, and accurately ejecting the nano-silver conductive ink to the specific position to form image information. The infrared solidifying device or photon sintering solidifying device is used for analyzing the curing work instruction, post-processing and curing the printed ink image nano-silver. The light emitting device comprises light emitting paper, conductive layer and power supply driver. The light emitting paper comprises substrate layer, light emitting layer and insulating layer. The substrate layer is a transparent conductive film and used as the first electrode of the light-emitting paper. The light emitting layer comprises light emitting powder and binder, and the printing thickness is 30-40 m. The mixing ratio of the light emitting powder and binder is 1:1.2-1.8:1. The insulating layer is formed by mixing insulating dielectric material and organic polymer, and the printing thickness is 20-30 m. The mixing ratio of the insulating dielectric material and organic polymer is 1:1.2-1.8:1. The light emitting paper is sequentially coated with luminescent powder and insulating dielectric material on the surface of the transparent conductive film to form a material with a standardized paper size. The conductive layer comprises nano-silver conductive ink jet ink printed on the surface of the insulating layer by post-processing and curing, and is used as the second electrode of the light-emitting paper. Simultaneously, the ink-jet printing nano-silver ink can realize the patterning preparation of the light-emitting image. The power supply driver can load alternating current (AC) voltage between the first electrode and second electrode. The working voltage is 80-120 V. The working frequency is 800-1400 Hz. The printed nano-silver conductive ink pattern can be lightened. The luminous image shape of the light-emitting paper is consistent with the image shape of the printed nano-silver conductive ink. An INDEPENDENT CLAIM is included for ink jet printing direct light emitting imaging process using the ink jet printing light emitting imaging system.
