SCAN SIGNAL DRIVER AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18347489 titled 'SCAN SIGNAL DRIVER AND DISPLAY DEVICE INCLUDING THE SAME
The patent application describes a scan signal driver that outputs scan signals during an active period and sensing signals during a vertical blank period.
- Sensing control circuit supplies gate-on voltage to sensing control node in response to holding control signal during active period
- Output node control circuit supplies gate-on voltage to pull-up node when sensing control node's gate-on voltage is output during vertical blank period
- Output circuit outputs scan clock signal as sensing signal to scan signal lines when gate-on voltage is supplied to pull-up node during vertical blank period
Potential Applications: - This technology can be used in display panels, image sensors, and other electronic devices requiring precise signal control. - It can enhance the performance of devices that rely on accurate timing and signal transmission.
Problems Solved: - Provides a method for sequential output of scan and sensing signals, improving signal processing efficiency. - Enables selective output of sensing signals during specific periods, enhancing overall device functionality.

Questions about the technology: 1. How does the sensing control circuit determine when to supply the gate-on voltage to the sensing control node? 2. What are the specific advantages of selectively outputting sensing signals during the vertical blank period?
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.
