SCAN SIGNAL DRIVER AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240194146 titled 'SCAN SIGNAL DRIVER AND DISPLAY DEVICE INCLUDING THE SAME
The patent application describes a scan signal driver that sequentially outputs scan signals during an active period and selectively outputs sensing signals during a vertical blank period.
- Sensing control circuit supplies gate-on voltage to a sensing control node in response to a holding control signal during the active period.
- Output node control circuit supplies gate-on voltage to a pull-up node when the gate-on voltage of the sensing control node is output during the vertical blank period.
- Output circuit outputs a scan clock signal as a sensing signal to one of the scan signal lines when the gate-on voltage is supplied to the pull-up node during the vertical blank period.
Potential Applications: - This technology can be used in display panels, medical imaging devices, and industrial automation systems.
Problems Solved: - Efficiently outputting scan and sensing signals in different periods. - Controlling the voltage supply to specific nodes for accurate signal transmission.
Benefits: - Improved signal accuracy and timing. - Enhanced performance in devices requiring precise signal control.
Commercial Applications: - Display panel manufacturing for high-resolution screens. - Medical imaging equipment for accurate diagnostics. - Industrial automation systems for efficient operation.
Questions about the technology: 1. How does the sensing control circuit determine when to supply the gate-on voltage? 2. What are the specific advantages of using this scan signal driver in medical imaging devices?
Original Abstract Submitted
a scan signal driver includes: stages to sequentially output scan signals in an active period, and to selectively output sensing signals in a vertical blank period. at least one of the stages includes: a sensing control circuit to supply a gate-on voltage to a sensing control node in response to a holding control signal during the active period, and to output the gate-on voltage of the sensing control node in response to a selectively input line select signal during the vertical blank period; an output node control circuit to supply the gate-on voltage to a pull-up node when the gate-on voltage of the sensing control node is output during the vertical blank period; and an output circuit to output a scan clock signal as a sensing signal to one of scan signal lines when the gate-on voltage is supplied to the pull-up node during the vertical blank period.
