Title:
LIQUID CRYSTAL DISPLAY PIXEL DRIVE CIRCUIT AND TFT SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2018/184258
Kind Code:
A1
Abstract:
Provided are a liquid crystal display pixel drive circuit and TFT substrate. The liquid crystal display pixel drive circuit comprises: a plurality of subpixels (10) arranged as an array, each subpixel (10) comprising: a primary region thin-film transistor (T1), a primary region charge-sharing thin-film transistor (T2), a secondary region thin-film transistor (T3), a secondary region charge sharing thin-film transistor (T4), a primary region storage capacitor (C1), a secondary region storage capacitor (C2), a primary region liquid crystal capacitor (C4), and a secondary region liquid crystal capacitor (C3); The secondary region charge-sharing thin-film transistor (T4) and primary region charge-sharing thin-film transistor (T2) access a first and second array-substrate common voltage (Acom1, Acom2) and, by means of adjusting the magnitude of the first and second array-substrate common voltages (Acom1, Acom2), regulate the common voltage of the display; thus the difficulty and accuracy in adjusting the optimal common voltage of the liquid crystal display are reduced, improving the optimal common-voltage adjustment efficiency and display performance.
