A composition, an OLED device and an OLED display panel. The composition includes a low-mobility metal complex material of bias-electron-transport-type in a mass percentage of 1% to 99% and an organic electron transport material in a mass percentage of 1% to 99%, wherein an electron mobility of the low-mobility metal complex material of bias-electron-transport-type is less than 1*Ecm/Vs. The influence of the electric field and the temperature on the electron mobility in the electron transport layer can be reduced, the balance of a carrier system in a high temperature environment is better, and the service life in the high temperature environment is long.

Composition, OLED device and OLED display panel

A voltage regulating module includes a fine regulating charge pump and a voltage-multiplying charge pump. The first output voltage of the fine regulating charge pump is V=m*V, a second output voltage of the voltage-multiplying charge pump is V=n*V, and a total output voltage of the voltage regulating module V=V+V. Vis an input voltage, a value of m ranges from 0 to 1, and n is an integer greater than or equal to 1.

Voltage regulating module and implantable nerve stimulation system

Provided is a stimulation source generation circuit for a nerve stimulator. A power module supplies an input voltage. A boosting module boosts the input voltage and generates a stimulation source. A charge branch of the boosting module includes an inductor and a first MOS tube. A discharge circuit includes a second MOS tube and an output branch for outputting the stimulation source. An adjustment module outputs an operating frequency according to a magnitude of the stimulation source. The adjustment module is further connected to control ends of the first MOS tube and the second MOS tube and adjusts on or off of the first MOS tube and the second MOS tube according to the operating frequency. The first MOS tube and the second MOS tube cannot be turned on at the same time.
