A low power display driver with simultaneous image transformation

Abstract

In this thesis, I designed, implemented, and evaluated the energy consumption of a system that uses a liquid crystal display to perform a one-dimensional transform. The RMS response of the liquid crystal elements themselves were exploited to perform a matrix multiplication (image transformation) over a single frame period. This image transformation was used as the last step of the decompression process in an image processing system. The system was implemented first in Matlab, then as a printed circuit board, and finally as an integrated circuit. While the initial Matlab and printed circuit board implementations looked promising, a number of practical considerations arose during the integrated circuit design that ultimately resulted in moderate performance: 14.3% energy savings.
