- Section 3. To compensate for the leakage current, the storage capacitor must be very large; here, the capacitance is 34 pF. A polysilicon TFT is preferable to an amorphous silicon TFT for the switching transistor, because the large capacitor must be charged during the short pixel selection period.
- EPD driven to produce greyscale
- I. ...we have reported the world's first active-matrix EPD at an international electron device meeting (IEDM 2000)[12]. Since then, a few displays combining TFTs and microencapsulated electrophoretic materials have also been introduced [13]-[16].
- I. Microencapsulated electrophoretic material in this EPD was driven by poly-Si TFTs fabricated with a low temperature process...

- 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.
