Title:
GATE DRIVER UNIT MONOLITHIC, GATE DRIVER MONOLITHIC AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/227909
Kind Code:
A1
Abstract:
A gate driver unit monolithic, a gate driver monolithic and a display apparatus. The gate driver unit monolithic is suitable for multi-stage connection to form the gate driver monolithic, and comprises a memory compensation module (05), wherein the memory compensation module (05) comprises a compensation sub-module (05A), a memory sub-module (05B) and a secondary memory sub-module (05C); at an early touch control detection stage, the memory compensation module (05) copies voltage information of a pull-up control node (netAn) and transfers same to a first memory compensation node (netCn) and a second memory compensation node (netDn); at a touch control detection stage, the voltage of the pull-up control node (netAn) is pulled down to a second stage voltage; and at the later touch control detection stage, the voltage of the pull-up control node (netAn) is pulled up to a first stage voltage. At a touch control detection stage, pull-up control nodes (netAn) at all stages are maintained at a low potential, thereby eliminating cross display stripes caused by the difference between characteristic drifts of thin-film transistors (M10) in a pull-up module (02).
