Active matrix liquid crystal display incorporating pixel inversion with

Abstract

An AMLCD display and bootstrapped pixel drive method incorporating pixel inversion. Each of a plurality of pixel assemblies arranged in a matrix of rows and columns includes a display element having a display electrode, and a semiconductor device having a control port, an input port and an output port, with each output port connected to a corresponding display electrode. Each of a plurality of bootstrap lines are additionally connected to a display electrodes of a plurality of rows of pixel assemblies, and a data line connects each input ports of pixels arranged along a column. A plurality of gate lines is provided with each gate line associated with a row of pixels in the matrix and connected to control ports of pixel assemblies in the row for receiving gate line pulses. The control ports of semiconductor devices associated with pixels located on two adjacent rows are alternately connected to either one of two associated gate lines in an interleaved fashion. A bootstrap pulse in timed relation with gate line pulses applied to each of two gate lines associated with the pixels of two adjacent rows is applied to the bootstrap lines in a timed relation such that display electrodes of alternately connected interleaved pixels of two adjacent rows shift in voltage in a first time frame and successive time frames, and enables display electrodes of remaining alternately connected interleaved pixels of two adjacent rows of pixels to shift in voltage in a second time frame and successive second time frames.
