Abstract
An electronic device may include a display panel and a display driver. The display panel may include multiple pixels each receiving a supply voltage and a respective data voltage to emit light. The display driver may include a low drop-out regulator (LDO) to provide the supply voltage to the pixels. The LDO may operate in a normal operation mode and a hard park mode. In the normal operation mode, the LDO may generate the supply voltage based on receiving a reference voltage and a bias voltage within a bias voltage range to operate in the normal operation mode. In the hard park mode, the LDO may become idle (e.g., shut-down mode) based on receiving a hard park mode voltages from dedicated replacement circuits. For example, including the dedicated reference voltage replacement circuit with the display driver may improve reliability and efficiency of the electronic device when de-energizing the LDO.
