PINS 1 & 2 (Vdd & Vss): J3 short, by adding a resistor on R9.

PINS 15 & 16: J4 short, by adding a resistor on R8.

NOTE: The brightness can be controlled by the value of R8 or R9.

3. Reference table for establishing the relationship between the temperature

range, viewing direction and type of polarizer:

4. Differences between a driver IC, a controller IC and a controller/driver IC:

Driver IC: There are two types of driver IC's. One is a "common" driver and the other

a "segment" driver. Common drivers output signals to create the rows or number of

lines while the segment drivers output the necessary signals to create the characters

or columns.

Controller IC: This IC receives data written in ASCII or JIS code from the MPU and

stores this data in RAM. This data is then converted into a serial character pattern and

transferred to the LCD driver IC.

Driver/Controller IC: It is most commonly found in a graphics module. It receives

data from the MPU and stores it in RAM. It accepts commands directly from the MPU

for both the common and segment drivers.

5. Following is the minimum dot size and pitch on the LCD, the ITO line on

the LCD and the elastomer (zebra) connector:
