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 column driver comprises dual shift register arrays, one array coupled to the even columns and the other array coupled to the odd columns. The even and odd columns operate at opposite polarities. The respective polarities are reversed on every frame by a polarity switch the polarity switch coupled to a video signal amplifier. The control apparatus further comprises sensors for generating a gray-scale feedback signal to adjust the amplifier gain. The sensors comprise a temperature sensor within the active matrix and a light sensor measuring light transmission through the liquid crystal material.
