Control system for display panels

A control apparatus for driving an active matrix liquid crystal display in response to a stream of video signals from a video source, the display having an array of pixel transistors in between a substrate and an opposing substrate, the array being in a single crystal silicon layer of a silicon-on-insulator (SOI) structure, the pixel transistors addressed by a plurality of row lines and column lines, the apparatus comprising:

• an adhesive layer bonding the single crystal silicon layer to a substrate;
• a first select scanner and a second select scanner in the single crystal silicon layer and coupled to the video source and the row lines for addressing a select row of pixel transistors, each select scanner coupled to each row line at opposite sides of the active matrix region with each select scanner generating a simultaneous drive signal on the selected row line wherein each pixel transistor on the selected row line receives a portion of the drive signal from each select scanner;
• a data scanner in the single crystal silicon layer and coupled to the video source and the column line for driving the pixel transistors on the select row of pixel transistors in response to the video signals;
• and
• a temperature sensor formed with the single crystal layer between the substrate and the opposing substrate for sensing the temperature of the active matrix liquid crystal display.
