Your Android headunit has a screen behind the touch panel and a display for those millions of colors and icons. The display will either be based on the TN technology or the IPS system.
But which is better? (TN vs IPS)
TN
TN is short for Twisted Nematic. These LCD panels have been produced in mass for many years, and the technology to produce cheap TN panels in quantity is with us.
Advantages
The advantages of TN panels in an Android headunit are, firstly, the low cost, and they are cheap to produce and work well in an Android headunit.
Disadvantages
The disadvantages of TN are the poor color rendering, and they don’t look as good as your phone when you put them aside. Secondly, the viewing angle isn’t great, which may be more noticeable to some than others, depending on where the headunit is mounted.
IPS
IPS is shot for In-Plane Switching. IPS is a different way of producing displays and an improvement over the earlier TN displays.
Advantages
The advantages of IPS are a much better color rendering than TN with a deeper black. Also, the viewing angle of IPS is much improved over TN, and with a broader angle, it is still possible to view the screen detail when glancing at a sideways look rather than having to view directly at the screen.
Disadvantages
The disadvantage of IPS screens in the Android headunit is the increased cost of production. The increased cost to produce the superior screens is passed on to the customer through a higher price tag.
You won’t find IPS screens on many Android headunits because the increased cost of production is passed on to the customer, and that cost seems to be a significant factor in the purchase decision.
LCD
LCD is a liquid crystal display, and TN and IPS screens are both types of LCD.
If the sales listing states the screen is LCD, you can be sure it is TN because this is the base technology, the lowest specification of screen technology.
LED, OLED, PMOLED, AMOLED & VA LCD
None of these modern display technologies have made their way into any Android Headunit due to the higher manufacturing costs of producing these panels and the reluctance of customers to spend more for better specifications.
