POWER MANAGEMENT DRIVER AND DISPLAY DEVICE HAVING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18397128 titled 'POWER MANAGEMENT DRIVER AND DISPLAY DEVICE HAVING THE SAME
Simplified Explanation
The patent application describes a power management driver and a display device that includes a controller to control the timing of voltage output during different periods in response to a sensing control signal, and a fault detector to detect faults in the power line based on current flow.
- First power supply supplies different voltages to a pixel through a power line during sensing and display periods.
- Controller controls timing of voltage output during transition periods between display and sensing periods.
- Fault detector detects faults in the power line based on current flow during sensing period.
Potential Applications
The technology described in the patent application could be applied in various display devices such as smartphones, tablets, and monitors to efficiently manage power consumption and ensure proper functioning of the display.
Problems Solved
This technology solves the problem of inefficient power management in display devices, as well as the issue of detecting faults in the power line that could affect the performance of the device.
Benefits
The benefits of this technology include improved power efficiency, better display performance, and enhanced reliability by detecting faults in the power line.
Potential Commercial Applications
The technology could be commercially applied in the manufacturing of display devices for consumer electronics, medical devices, automotive displays, and other industries where efficient power management and fault detection are crucial.
Possible Prior Art
One possible prior art could be the use of power management drivers in display devices, but the specific implementation described in the patent application may be novel and inventive.
What is the specific technology used in the fault detector to detect faults in the power line?
The specific technology used in the fault detector to detect faults in the power line is not detailed in the abstract. Further information on the sensing mechanism or methodology employed would provide a clearer understanding of how faults are detected.
How does the controller precisely control the timing of voltage output during transition periods?
The abstract mentions that the controller controls the timing of voltage output during transition periods, but it does not specify the exact method or technology used for this precise control. Additional details on the control mechanism would be necessary to understand the specific implementation of this feature.
Original Abstract Submitted
A power management driver and a display device having the power management driver are provided, including a first power supply configured to supply a first voltage to a first driving power terminal of a pixel through a power line during a sensing period, and supply a second voltage to the first driving power terminal of the pixel through the power line during a display period; a controller configured to control timing at which the first voltage is output and timing at which the second voltage is output during a transition period between the display period and the sensing period in response to a sensing control signal; and a fault detector configured to detect a fault in the power line based on a current flowing through an output terminal during the sensing period.
