TFT liquid crystal display has a shift register that only uses a thin film transistor with the same type of channel and which acts as integrated circuit for shifting level

摘要

Liquid crystal display panel has a cell matrix, a command circuit for controlling scanning and a data generation circuit controlling the data lines of the display. The scanning control circuit has a first stage (ST1) comprising: a shift register equipped with an buffer output memory (54) controlled by the node voltages (QB); a second controller (52) for controlling the level shift (LS1); a third controller (58) and an output (60).
