Abstract: Disclosed are a light-emitting device, a display panel, and a driving method of the light-emitting device. The light-emitting device includes: a base substrate, a first electrode on a side of the base substrate, a second electrode on a side, facing away from the base substrate, of the first electrode, and at least two blue light-emitting layers located between the first electrode and the second electrode. Different blue light-emitting layers emit light with different wavelengths. The first electrode and the second electrode are configured to be applied with different voltages. A voltage difference between the first electrode and the second electrode includes a first threshold voltage and a second threshold voltage, and under control of the first threshold voltage, one of the blue light-emitting layers emits light; and under control of the second threshold voltage, another blue light-emitting layer emits light.

Abstract: A light emitting device includes: a first electrode; a second electrode disposed opposite to the first electrode; and multiple emission layers stacked between the first electrode and the second electrode. The emission layers include at least one first emission layer and at least one second emission layer. The first emission layer includes a first luminescent material, and is configured to emit a first light when driven by a current or voltage; the second emission layer includes a second luminescent material, and is configured to emit a second light when driven by the current or voltage; a luminous efficiency of the first luminescent material is greater than that of the second luminescent material; and a luminance conversion rate when performing optical excitation on color conversion materials by the first light is smaller than that when performing optical excitation on the color conversion materials by the second light.

Abstract: An organic light emitting device, a preparation method therefor, and a display apparatus are provided. The organic light emitting device includes an anode, a cathode, and a light emitting layer and an electron transport layer arranged between the anode and the cathode. The electron transport layer is arranged between the light emitting layer and the cathode. The electron transport layer includes a first host material and a second host material. A mixing ratio of the first host material to the second host material of one side of the electron transport layer close to the light emitting layer is different from a mixing ratio of the first host material to the second host material of one side of the electron transport layer away from the light emitting layer.
