1. PINS 1 & 2 (Vdd & Vss): J3 short, by adding a resistor on R9.
2. 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:
: There are two types of driver IC's. One is a "common" driver and the other
Driver IC
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.
: This IC receives data written in ASCII or JIS code from the MPU and
Controller IC
stores this data in RAM. This data is then converted into a serial character pattern and
transferred to the LCD driver IC.
: It is most commonly found in a graphics module. It receives
Driver/Controller IC
data from the MPU and stores it in RAM. It accepts commands directly from the MPU
for both the common and segment drivers.
