SCAN DRIVER AND DISPLAY DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17944044 titled 'SCAN DRIVER AND DISPLAY DEVICE

Simplified Explanation

The patent application describes a scan driver that includes several stages for controlling voltage signals. Here is a simplified explanation of the abstract:

  • The scan driver has an input block that changes the voltage of a first node based on an input signal.
  • A second node control block controls the voltage of a second node using a first clock signal and the voltage of the first node.
  • A scan output block outputs a second clock signal as a scan signal based on the voltage of the first node, and also outputs a gate off voltage as the scan signal based on the voltage of the second node.
  • A carry output block outputs the second clock signal as a carry signal based on the voltage of the first node, and also outputs a different gate off voltage as the carry signal based on the voltage of the second node.
  • A first node control block transfers the carry signal to the first node based on a next carry signal.

Potential applications of this technology:

  • Integrated circuits and semiconductor devices
  • Testing and debugging of electronic systems

Problems solved by this technology:

  • Efficient control of voltage signals in scan drivers
  • Accurate transfer of carry signals

Benefits of this technology:

  • Improved performance and reliability of scan drivers
  • Enhanced testing capabilities for electronic systems


Original Abstract Submitted

A scan driver includes stages including an input block to change a first node voltage to a gate on voltage based on an input signal, a second node control block to control second node voltage based on a first clock signal and the first node voltage, a scan output block to output a second clock signal as a scan signal based on the first node voltage, and to output a first gate off voltage as the scan signal based on the second node voltage, a carry output block to output the second clock signal as a carry signal based on the first node voltage, and to output a second gate off voltage different from the first gate off voltage as the carry signal based on the second node voltage, and a first node control block to transfer the carry signal to the first node based on a next carry signal.
