Claim Text:
1. A method for manufacturing an organic light-emitting diode (OLED) display panel, comprising: placing a base substrate provided with pixel electrodes of pixel units into an evaporation chamber; electrically charging pixel electrodes of pixel units, required to be deposited with a material, on the base substrate, electrically charging electrodes disposed at an evaporation source in the evaporation chamber, and forming an electric field; placing an evaporation material corresponding to the material required to be deposited into the evaporation source, ionizing the evaporation material, and depositing the ionized evaporation material on the base substrate under the action of the electric field; and etching the base substrate provided with the ionized evaporation material by an etching process, and retaining the evaporation material only on the previously charged pixel electrodes on the base substrate.
