Silicon-based OLED light-emitting device, display and preparation method

The invention discloses a silicon-based OLED light-emitting device, a display and a preparation method, and relates to the technical field of display devices. A silicon-based OLED light-emitting device comprises a substrate layer, the top of the substrate layer is provided with at least three anode units capable of generating different photon pixels, and the tops of the anode units are provided with cathode units matched with the anode units. At least one light-emitting component is arranged between the anode unit and the cathode unit, the light-emitting component can be driven by electric field force generated by the anode unit and the cathode unit to enable holes and electrons to interact to generate light beams, a light extraction layer is arranged on the cathode unit, and a packaging layer is arranged on the light extraction layer. The packaging layer is provided with color films which are opposite to the anode units in position and have the same color with the anode units, and the number of the color fil
