Low power strategy for a TFT controller

In this paper a low power strategy for a TFT controller is described. The design is based on a general controller for high resolutions graphic display data. The main improvements introduced concerns not only an effective power reduction of about 65.42%, compared with the original module, but also the new feature that allows one to choose among six different functional configurations. The new TFT controller works also with the new display generation such as organic LED (OLED) type, in this case we introduce the possibility to power down the backlighting neon. Measures are made with design compiler (Synopsys) to compute the TFT controller power consumption and the total cell area before and after our modifications.
