Abstract

The invention provides a specific structure of an OLED illumination panel. In the technical scheme, on the basis of the prior art, a dispatching lead is disposed in a non-effective light emitting areato introduce an electrical signal in a binding area into an effective light emitting area. Preferably, a PWM wave generated by a single chip microcomputer in a printed circuit board is input into a driving chip, and modulation waveforms with different pulse widths can be output through the scheduling lead. Finally, the on-off control of the effective light emitting area of an OLED screen body isrealized by introducing the modulation waveform on the effective light emitting area of the OLED screen body, and in addition, the brightness uniformity of the screen body is adjusted by adjusting theduty ratio and the amplitude of the modulation waveform.

Description

technical field [0001] The present disclosure generally relates to the technical field of organic electroluminescent devices, and specifically relates to an OLED lighting panel. Background technique [0002] OLED devices usually have a sandwich structure, and a glass substrate or a flexible substrate is covered with an anode with good light transmission, such as indium tin oxide (English full name is Indium Tin Oxide, referred to as ITO), and a hole injection layer is sequentially deposited on the ITO anode. , hole transport layer, organic light-emitting layer, electron transport layer, electron injection layer and other functional layers, then vapor-deposit cathode metal materials, and finally package. [0003] Traditional OLED lighting modules are mostly in the form of an OLED screen plus an FPC, that is, the lighting and brightness adjustment functions are realized through an external control board to achieve the purpose of lighting. However, in the prior art, when the l...
