Contrast
LCD Glass
Although contrast is heavily dependent on the light source available and the multiplex mode, it
also varies with the LCD voltage levels. As previously seen, a potentiometer is used to control
the contrast of the LCD panel. The potentiometer sets the separation between each of the LCD
voltages. The larger the separation, the better the contrast achievable.
The characteristics of the LCD glass vary depending on the materials used.
