A display panel, a light-emitting device, and a driving method thereof are provided. The light-emitting device includes a substrate, and a first electrode, a first light-emitting unit, a connecting layer, a second light-emitting unit, and a second electrode stacked up sequentially on the substrate. Polarities of the first electrode and the second electrode are opposite and reverse periodically in order that the first light-emitting unit and the second light-emitting unit illuminate alternately.

Display panel, light-emitting device, and driving method thereof

A method of preparing a film and a light-emitting device are disclosed. The method includes: providing at least one gas-phase source above a substrate, the at least one gas-phase source made of materials comprising a perovskite material; and controlling an evaporation rate of the at least one gas-phase source to form a perovskite film. In the method provided by the present invention, a perovskite light-emitting layer is prepared by gas-phase source evaporation coating without an organic solvent, which avoids miscibility between the organic solvent and other layers and improves compatibility between the perovskite material and other film materials, thereby realizing the low preparation cost and the simple preparation process.

The light-emitting device includes an anode, a hole transport layer, a light-emitting layer, an electron transport layer, and a cathode all laminated together. The hole transport layer is treated with a high boiling point polar solution to reduce a Coulomb force of the hole transport layer. The light-emitting device of the present application can improve light-emitting efficiency of the light-emitting device.

Light-emitting device having surface-treated hole transport layer and manufacturing method thereof

The present disclosure provides a micro light emitting diode display panel, a method for fabricating the same, and a display device comprising the same. The micro light emitting diode display panel includes an active layer, a gate insulating layer, a gate electrode, a source electrode, a drain electrode, a pixel electrode, a micro light emitting diode, and a gate insulating layer covering the active layer, the gate insulating layer, the gate electrode, the source electrode, and the drain electrode. The light shielding layer blocks light emitted by the micro light emitting diode from being incident on the thin film transistor, thereby reducing influence of the light emitted by the micro light emitting diode light on the thin film transistor.
