Abstract: An OLED display system includes a display panel, a driving circuit, a voltage generator and a power management application circuit (PMAC). The driving circuit provides scan signals to the display panel. The voltage generator generates a negative voltage based on a first driving voltage having a positive level and a second driving voltage having a negative level and provides the negative voltage to the driving circuit. The PMAC includes a power management application circuit (PMIC) and an additional circuit distinct from the PMIC and disposed externally to the PMIC. The PMIC applies a high power supply voltage and a low power supply voltage to the display panel and generates the first driving voltage based on a battery voltage. The additional circuit generates the second driving voltage based on the battery voltage. The driving circuit generates at least one of the scan signals based on the negative voltage.

Abstract: Methods and apparatuses in a wireless communication system is provided. Configuration information for defining a downlink assignment for a bandwidth part (BWP) is transmitted to a user equipment (UE) by higher layer signaling. At least one BWP is configured in a cell of the base station and the higher layer signaling is UE specific. An activated BWP is identified. Downlink control information (DCI) is transmitted on the activated BWP. Data is transmitted to the UE on the activated BWP according to the downlink assignment for the activated BWP. The downlink assignment is defined on the activated BWP, based on both the configuration information by the higher layer signaling and remaining information by the DCI.
