FSTN vs HTN vs DSTN Who is the best？
TN is an abbreviation of Twisted Nematic. TN display mode is the first active display developed and used. TN LCD has a relatively simple structure and uses 4mask technology, so the cost is lower. However, due to the structure and circuit design, TN displays have lower resolution, especially those of small size. The highest resolution is FW (480×854). TN LCDS have poor viewing angles and low contrast due to the arrangement of liquid crystal molecules. TN displays also have the advantage of low cost and high response speed due to the thin liquid crystal layer.
Principle of TN mode liquid crystal display
Display white when not working
Black is displayed in working state
TN type display is also in continuous development, such as DSTN LCD display and FSTN LCD display technology
1.DSTN display structure and principle
DSTN is double Twisted Nematic, which uses two TN LCD superimposed to achieve better display effect
2.FSTN display structure and principle
FSTN(Film compensated STN) represents the black and white display on the TN display by adding a compensating film to the polarizer.
Comparison of DSTN LCD display and FSTN LCD display
| Advantages | Disadvantages | |
| DSTN | 1.Negative and positive Mode 2.Transmissive and transflective Mode 3.Duty Ratio: 1:8 to 1:64 4.High reliability 5.Automotive compensation(-30°C to +85°C) 6.Colour neutral 7.Excellent performance with all backlight systems | 1.Temperature compensation necessary 2.Response time increased at 3.lower temperature 4.Higher cost 5.Too Heavy |
| FSTN | 1.Positive Mode 2.Transmissive, transflective and reflective Mode 3.Duty Ratio: 1:8 to 1:240 4.High reliability 5.High contrast 6.Colour neutral 7.Light | 1.Temperature compensation necessary 2.Response time increased at lower temperature 3.Colour changes vs temperature 4.Colour changes vs viewing angle 5.Consumer compensation(0° to +60°C) |
