POWER CONTROL DEVICE AND CONTROL METHOD OF DISPLAY - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240212630 titled 'POWER CONTROL DEVICE AND CONTROL METHOD OF DISPLAY
Simplified Explanation: The power control device of a display apparatus encodes control command data into a power control signal to adjust the source voltage level for the display panel and panel driver based on the data.
- The device includes a display panel with pixels, a panel driver, a power control unit, and a power source unit.
- The control command data consists of control pulses with alternating logic low and high periods, with varying lengths for the logic low period.
Key Features and Innovation:
- Encoding control command data into a power control signal for adjusting the source voltage level.
- Utilizing control pulses with alternating logic low and high periods to regulate the power output.
- Varying the lengths of the logic low period to achieve different power control effects.
Potential Applications:
- Display devices such as televisions, monitors, and digital signage.
- Mobile devices with display screens.
- Automotive display systems.
Problems Solved:
- Efficient power management for display panels.
- Precise control of the source voltage level.
- Enhanced performance and energy savings.
Benefits:
- Improved display quality.
- Energy efficiency.
- Extended lifespan of display components.
Commercial Applications: Power control devices for various display applications in consumer electronics, automotive, and digital signage industries.
