In the world of display technologies, businesses must decide which technology best fulfills their needs.
In this article, you will discover the unique differences between two popular ones – Thin Film Transistor (TFT) and Active Matrix Organic Light Emitting Diodes (AMOLED). This will assist you in making decisions for your business.
What is TFT Display?
TFT is a type of display that uses an inorganic thin film transistor to improve the quality of images.
It is made with several layers that control each pixel. These layers include (1) backlight (2) color filter, and (3) liquid crystal layer.
Each pixel has four transistors which form colors red, blue and green. These transistors are lit when the electrode in the liquid crystal layer is activated. The fourth transistor is for brightness.
What is AMOLED Display?
AMOLED uses organic materials that give out light when current flows through it. Unlike TFT, you don’t need a backlight for AMOLED displays. Each pixel can generate light on its own.
AMOLED displays have several layers: (1) anode (2) organic middle (3) cathode (4) substrate layers.
The anode discharge electrons. The organic layer activates the pixels. Electrons are inserted by the cathode layer. The substrate layer is the foundation’s base.
AMOLED displays are energy-efficient. Thus, they are flexible for use in wristwatches and outdoor signage.
Key Differences in TFT vs AMOLED
Use of Power
TFT: It consumes a lot of power because it requires a backlight. As a matter of fact, it still consumes power when the color black is off.
AMOLED: It saves energy as each pixel can discharge light itself.
Color Performance
TFT: Its color performance is poor. It produces quality images, but does not produce deep blacks. It also gives distorted images when viewed from a distant angle.
AMOLED: It gives brighter and higher contrast images. It also displays deeper blacks, giving you minimal distortion.
Price and Availability
TFT: Displays are affordable and widely available. Hence, if your project is budget-conscious, this is a good fit.
AMOLED: The cost is higher than TFT. You can go for this if you choose premium over price.
Refresh Rate
TFT: Displays may take a longer time to update what is on its screen. Some only have about 50-60 Hz.
AMOLED: Displays can update its content quickly and smoothly. You can find most to have 144Hz.
Lifespan and viewing angle
TFT: It is very durable, with an extended lifespan. But, its viewing angle is not wide.
AMOLED: It is not as durable as TFT. The organic materials depreciate with time. But, it has a wide viewing angle, up to about 160 degrees.
Applications
TFT: It is applied in technologies that hit on image quality. Computer monitors, cell phones, tvs, cameras are good examples.
AMOLED: It is used in technologies that priorities energy efficiency. Smartwatches are good examples.
TFT vs AMOLED: Which one is Better?
No digital technology is best, just find the one that fulfills your business needs. If you prioritize high-color performance and have the money to spend, you can choose AMOLED. If you are considering cost and image quality, you can choose TFT.
You should note that TFT displays have been around more than AMOLED so you can easily get access to them. But the final decision resides with you so think carefully.
Conclusion
The difference in tft vs amoled is clear. Your choice should depend on your business’ budget, needs as well as features. Invest in the right one as it will help you make good and strategic decisions.
