The patent application describes an electronic device featuring a rollable display integrated within two housings. The second housing is movable relative to the first, allowing the display to be rolled in or out. This innovation addresses the challenge of providing large, portable screens without sacrificing convenience. The device supports wireless charging, with a dedicated integrated circuit (IC) managing power received from external sources to charge an internal battery.
The device includes a processor that dynamically adjusts the charging current based on the position of the second housing—either slid in or out. This adjustment helps optimize charging efficiency and manage heat dissipation. An antenna connected to the wireless charging IC facilitates power reception, and a temperature sensor monitors internal conditions to ensure safe operation.
The processor determines two distinct current levels for charging: one when the display is rolled in and another when it is extended. The device can switch between these modes based on usage and temperature conditions. If temperatures exceed certain thresholds, the processor reduces current flow to prevent overheating, thus maintaining efficiency and safety.
The system includes a temperature sensor that feeds data to the processor, which then adjusts charging parameters accordingly. Notifications can alert users to adjust the housing position to manage heat effectively. This proactive approach helps maintain optimal performance and extends battery life by avoiding excessive heat build-up.
The device also incorporates a drive module for automatic movement between housing states when charging begins, enhancing user convenience. By intelligently managing power and thermal conditions, this design offers a balanced solution for modern portable devices requiring large displays without compromising on safety or functionality.
