SCAN DRIVER AND DISPLAY DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 17847732 titled 'SCAN DRIVER AND DISPLAY DEVICE INCLUDING THE SAME
Simplified Explanation
The abstract describes a scan driver that consists of multiple stages, each with its own controller and output circuit. The controllers control the voltage levels of different control nodes and generate carry signals. The output circuit includes pull-up and pull-down transistors that output a scan signal based on the voltage levels.
- The scan driver includes multiple stages, each with its own controller and output circuit.
- The controllers control the voltage levels of specific control nodes and generate carry signals.
- The output circuit consists of pull-up and pull-down transistors.

Original Abstract Submitted
A scan driver includes a plurality of stages, each of the plurality of stages including: a first controller to control voltage levels of a first control node and a second control node in response to a first start signal and a second start signal, and to output a first carry signal; a second controller to control voltage levels of a third control node and a fourth control node in response to the first start signal and the second start signal, and to output a second carry signal; and an output circuit including: a pull-up transistor having a gate connected to the first control node; and a pull-down transistor having a gate connected to the third control node. The output circuit is to output a scan signal based on an on voltage output through the pull-up transistor and an off voltage output through the pull-down transistor.
