The invention discloses a method and device for improving OLED display brightness uniformity, relates to the technical field of organic light-emitting devices, and aims to solve the problems that the display brightness of the device cannot be freely adjusted in the using process of the existing organic light-emitting device, and the overall uniformity of the light-emitting surface of the device is poor. The method comprises the following steps of: 1, connecting a power box to a circuit of a small transformer and a control switch, respectively connecting the small transformer and the control switch to an outer shell of a device and an input end of an electric push rod, and starting a power supply switch of the power box to supply power; and 2, after electrification, holes generated by the anode plate and electrons generated by the cathode plate move under the action of an electric field and are injected and migrated to the light-emitting layer to the HIT cave injection layer and the ET electron transport layer respectively, when the HIT cave injection layer and the ET electron transport layer meet each other in the light-emitting layer, energy excitons are generated, light-emitting molecules are excited to finally generate visible light, and the visible light is emitted to the device. Visible light is emitted through the glass base.
Description
technical field [0001] The invention relates to the technical field of organic light-emitting devices, in particular to a method and a device for improving the uniformity of OLED display brightness. Background technique [0002] OLED, also known as organic electric laser display, organic light-emitting semiconductor, OLED is a current-type organic light-emitting device, which is a phenomenon of luminescence caused by carrier injection and recombination. The luminous intensity is proportional to the injected current. OLED Under the action of the electric field, the holes generated by the anode and the electrons generated by the cathode will move, inject into the hole transport layer and the electron transport layer respectively, and migrate to the light-emitting layer. When the two meet in the light-emitting layer, energy excitation will be generated. molecules, thereby exciting the light-emitting molecules and finally producing visible light. [0003] Existing organic light...
