ABSTRACT:
A control apparatus for an active matrix liquid crystal display device is fabricated with the active matrix as a single integrated SOI circuit. The control apparatus and the active matrix are lifted from a silicon substrate and transferred to a glass substrate as a single piece. The control apparatus comprises a video interface, a column driver, and dual row drivers. The video interface operates the active matrix as a multiple-frequency scanning display device. The polarities of the display pixels are reversed on every frame by a polarity switch coupled to a video signal amplifier. The control apparatus further comprises sensors for generating a gray-scale feedback signal to adjust the gain of the video amplifier. User control of the display is provided by a user interface.
