ELECTRONIC DEVICE COMPRISING BOOST CIRCUIT, AND METHOD FOR CONTROLLING SAME ELECTRONIC DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18242356 titled 'ELECTRONIC DEVICE COMPRISING BOOST CIRCUIT, AND METHOD FOR CONTROLLING SAME ELECTRONIC DEVICE
Simplified Explanation
The abstract describes an electronic device that includes a display, a battery, and a boost circuit. The boost circuit receives power from the battery and supplies a driving voltage to the display. The circuit includes various components such as switching devices, an inductor, an output capacitor, a blocking device, and a control circuit.
- The boost circuit is designed to generate a DC overdrive voltage to power the display.
- The control circuit controls the overdrive voltage by managing the blocking device, based on the system voltage.
- The system voltage is the input voltage of the boost circuit and is equal to or greater than a threshold voltage.
Potential Applications
- This technology can be applied in various electronic devices that require a boost circuit to power the display, such as smartphones, tablets, and wearable devices.
- It can also be used in other devices that utilize displays, such as digital cameras, portable gaming consoles, and navigation systems.
Problems Solved
- The boost circuit efficiently generates a DC overdrive voltage to power the display, ensuring optimal performance.
- The control circuit helps regulate the overdrive voltage, preventing any potential damage to the display or other components.
- The blocking device blocks leakage current from the battery, improving overall power efficiency and extending battery life.
Benefits

Original Abstract Submitted
An electronic device includes: a display; a battery; and a boost circuit to receive power from the battery and to supply a driving voltage to the display. The boost circuit includes: a first switching device connected to a first node; a second switching device connected to the first node; an inductor between an input terminal of the boost circuit and the first node; an output capacitor to generate a DC overdrive voltage by smoothing an AC current generated by the first switching device and the second switching device; a blocking device to block a leakage current of the battery; and a control circuit to control the overdrive voltage by controlling the blocking device, based on a system voltage that is equal to or greater than a threshold voltage, and wherein the system voltage is an input voltage of the boost circuit.
