FSTN vs TN LCD Technology
When deciding between FSTN vs TN LCDs, the decision comes down to lower cost vs sharper contrast and wider viewing angle. This is the choice to make when ordering a Liquid Crystal Display from FocusLCDs.com.
Note: LCDs are not the same as TFTs or OLEDs. LCDs have one color background and a different color character/segment. There are many advantages of LCDs over other display technologies, but I will not cover that in this article since I want to keep it short and I am almost about out of coffee.
Fluid used in Liquid Crystal Displays
LCDs are built with a fluid placed between two pieces of glass. There are three types of displays available: TN, STN and FSTN. Your choice of fluid determines how the display will look cosmetically.
LCDs with TN Fluid
TN types of displays are used in gas pumps, digital clocks and pagers
Quick facts about TN (twisted nematic) fluid.
- Lowest cost of the three: TN, STN and FSTN
- Better at colder temperatures
- Has a smaller viewing angle than FSTN
- Contrast is not as sharp as FSTN
Twisted Nematic [See photo below] was one of the first fluid technologies incorporated in LCD technology. The viewing angle is not as wide as STN or FSTN. Examples of TN LCD displays can be seen in pagers and gas pumps.
TN Benefits
- The best in colder temperatures since it has the fastest response time.
- Provides short response times.
- The lowest cost fluid available.
- Draws less power than the other fluid types.
