Electronic apparatus for controlling passenger seat display and method of controlling passenger seat display

An electronic apparatus for controlling a passenger seat display of a vehicle, the electronic apparatus comprising:

• the passenger seat display arranged on a dashboard of the vehicle in front of a passenger seat, the passenger seat display comprising a backlight unit (BLU), a viewing angle switching element comprising a polymer dispersed liquid crystal (PDLC), and a liquid crystal display panel;
• a sensor configured to detect an operating state of the vehicle being driven by a driver;
• a power supply configured to supply direct current (DC) power to the passenger seat display and the sensor;
• at least one processor connected to the power supply, sensor, and passenger seat display;
• and
• memory to connected to the at least one processor, the memory storing one or more instructions executable by the at least one processor, wherein execution of the one or more instructions by the at least one processor causes the at least one processor to perform a plurality of operations:
• obtaining operating state information of the vehicle from the sensor,
• determining an operating mode of the vehicle, which includes a driving mode and a stop mode, based on the obtained operating state information, controlling the power supply to apply a driving voltage to the viewing angle switching element, based on whether the vehicle is determined to be in motion, and
• adjusting brightness or color coordinates of the passenger seat display to a predetermined target brightness value or a predetermined target color coordinate value, respectively, when the driving voltage is applied to the viewing angle switching element.
