Abstract: Provided are pixel circuits using organic light emitting diodes (OLEDs) and a driving method thereof, and an organic light emitting display including the pixel circuits. The OLED is driven to emit light by a drive transistor generating a drive current compensated with respect to a threshold voltage difference and mobility deviation. The drive transistor may receive reference voltage and data signals in response to separate scan signals supplied to the pixel circuits via different scan lines. As a result, a threshold voltage compensation time, which may include the time during which a reference voltage is supplied to the drive transistor in response to a particular scan signal, may be set long enough regardless of a time during which the data signal is supplied to the pixel circuits located in respective rows of the organic light emitting display in response to a separate scan signal.

Abstract: An electronic apparatus is provided. The electronic apparatus includes an ultra-wideband (UWB) sensor, a memory storing at least one instruction, and a processor. The processor, by executing the at least one instruction, is configured to transmit a radar signal through the UWB sensor and receive a signal reflected by a user, acquire first information on the user's movement based on the reflected signal, acquire second information on the user's movement by performing a Fourier transform on the first information, acquire first feature information corresponding to the first information and second feature information corresponding to the second information by inputting the first information and the second information to a first neural network and a second neural network, respectively, acquire information on the user's sleep by inputting the first feature information and the second feature information into a third neural network, and provide information on the acquired sleep.
