The invention provides a light-emitting device and a drive control method and lamp of the light-emitting device, and relates to the technical field of semiconductor lighting. The light-emitting device comprises a plurality of light-emitting units and insulating layers, wherein the light-emitting units are stacked together and can emit light of different colors; the insulating layers are arranged between every two adjacent light-emitting units; the anodes of the light-emitting units are connected with the same anode voltage control circuit, and the cathodes of the light-emitting units are connected with a plurality of cathode voltage control circuits in a one-to-one correspondence mode; or the anodes of the light-emitting units are connected with a plurality of anode voltage control circuits in the one-to-one correspondence mode, and the cathodes of the light-emitting units are connected with the same cathode voltage control circuit; or the anodes of the light-emitting units are connected with the anode voltage control circuits in the one-to-one correspondence mode, and the cathodes of the light-emitting units are connected with the cathode voltage control circuits in the one-to-one correspondence mode. The light-emitting device can emit the light with various colors and can switch the emitting colors.
Description
technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to a light emitting device, a driving control method thereof, and a lamp. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) generally includes an anode, a light-emitting layer and a cathode, wherein the light-emitting layer is formed of an organic semiconductor material, driven by an electric field, the anode injects holes into the light-emitting layer, and the cathode injects electrons into the light-emitting layer , holes and electrons recombine in the light-emitting layer to excite the material of the light-emitting layer to emit light. Because OLED has the advantages of planar light emission, ultra-thin, transparent, flexible, high efficiency and energy saving, green and environmental protection, it has great development potential in the two major application fields of display and lighting, and has received extensive a...
