- 3.1: Whenever there is a screen change, the processor generates new data for the changing screen pixels and stores them into the framebuffer. This implies a higher energy consumption with increased temportal changes in the screen. Meanwhile, to maintain a screen on the LCD, the LCDC must sequentially read screen data from the frame-buffer and refresh the LCD pixels even when there is no screen change.
- 3.1: The display itself consists of several parts: LCD power circuitry, a front light, and an LCD. The LCDs used in the systems we studied are color active thin film transistor (TFT) LCDs. In such LCDs, each pixel has three comonents: R, G and B, signifying red, green and blue, respectively. Liquid crystals for each component are independently oriented by two polarizers, which are connected to a storage capacitor. The capacitor is in turn charged and discharged through a TFT to accommodate screen changes. Moreover, the capacitor must be refreshed at a high rate to maintain an appropriate voltage across the polarizers so that the corresponding liquid crystals remain properly oriented.
