LCD Basics
- LCD - Liquid Crystal Display:
An introduction to LCD technology. What is liquid crystal?
How the orientation of the its molecules are changed by electric field?
How characters and graphics are displayed?
- LCD Liquid Types:
TN, STN, FSTN or other types of LCD liquid. What is their
difference in terms of display quality and control strategy?
-
LCD Display Modes:
Dark image on light background, or vice versa. How to choose
between them in different circumstances?
-
LCD Polarizer Modes:
Reflective, transflective or transmissive. What is their
difference? How are they related to backlights?
-
LCD Viewing Direction:
6:00 o'clock, 12 o'clock or other directions? How is the
viewing direction defined? How to make the right decision that will suit
your application?
-
LCD Viewing Angle:
What is viewing angle vs. viewing direction? How viewing
angle is affected by the types of liquid and driving methods?
-
LCD Temperature Ranges:
LCD can work properly in a certain temperature range, which
is determined by the LCD fluid, polarizers, operational voltage, and
multiplex rate. LCD can also be optimized to work in certain temperature
ranges.
-
LCD Connection Types:
Elastomer (zebra strip), pin or heat seal are major types of
connection for LCD glasses to the rest of the circuitry. What is their
advantages and disadvantages?
-
LCD Backlighting:
