Abstract

The present application provides a specific structure of an OLED lighting panel. This technical solution is based on the prior art, and dispatching leads are arranged in the non-effective light-emitting area to introduce electrical signals in the bonding area into the effective light-emitting area. Preferably, the PWM wave generated by the single-chip microcomputer in the printed circuit board is input into the driver chip, and then different pulse width modulation waveforms can be output through the scheduling leads. Finally, by introducing a modulation waveform into the effective light-emitting area of ​​the OLED screen, the switch control of the effective light-emitting area of ​​the OLED screen is realized. In addition, the brightness uniformity of the screen is adjusted by adjusting the duty cycle and 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...
