LOW VOLTAGE FRAME BUFFER FOR HIGH CONTRAST LCD MICRODISPLAY AND METHOD THEREFOR

摘要

A frame buffer coupled to a LCD pixel comprises a first storage stage and a second storage stage. The frame buffer stores video information to the first storage stage while the second storage stage outputs previously stored video information to the LCD pixel. Video information stored in the first storage stage has a first voltage magnitude. A voltage boost circuit increases the stored video information in the first storage stage to a second voltage magnitude when the second storage stage is coupled for receiving video information from the first stage. The video information of the second voltage magnitude is converted and stored in the second storage stage having the first voltage magnitude.
