The present disclosure proposes an OLED pixel compensation circuit and an OLED pixel compensation method. The OLED pixel compensation circuit includes an OLED, a driving transistor, a first TFT, a second TFT, a third TFT, a fourth TFT, a first capacitor, and a second capacitor. The present disclosure adopts 5T2C structure and the driving transistor is a double gate TFT to compensate the variance of the threshold voltage such that the luminance evenness is raised and the lifetime of the product is extended.

OLED pixel compensation circuit and OLED pixel compensation method

An electricity transmission sending device includes: a transmission circuit and a coil, where the transmission circuit includes a signal sending unit and a controlling unit, and the coil includes at least two mutually perpendicular subcoils. The signal sending unit is configured to receive a required power signal and an actually received power signal that are sent by the electricity transmission receiving device; and the controlling unit is configured to adjust a magnetic field direction in which wireless electricity transmission to the electricity transmission receiving device is performed and control the coil to transmit electric energy to the electricity transmission receiving device in an optimal magnetic field direction, where the optimal magnetic field direction refers to a corresponding magnetic field direction when a power value of electric energy actually received by the electricity transmission receiving device is maximum in a case of specific output power of the coil.
