7. Comparison between TN, STN and FSTN technologies:

Remarks: with 1 being the best or most expensive and 3 the worst or least expensive.

8. Differences between reflective, transflective and transmissive displays

Reflective: Such display includes a diffuser. This layer reflects the light that enters the

front of the display. Reflective displays require ambient light for the light source since

there is no backlight.

Transflective: As type of backing which is bonded to the rear polarizer. Enables light

to pass through the back, as well as reflecting light from the front.

Transmissive: A type of LCD which does not have a reflector or transflector

laminated to the rear polarizer. A backlight must be used with this type of LCD

configuration. The most common is a transmissive negative image.

9. Considerations for attaining a 3.0 Volt LCD module:

IC: Choose the ICs that can be driven at 3.3V or less. Below is a list of IC's that can

accomplish this requirement:

Controller:

KS0066U 2.7 ~ 5.5V

KS0070B 2.7 ~ 5.5V

HD44780U 2.7 ~ 5.5V

Driver:
