What is the difference between PMOLED, AMOLED, and TFT displays in smartphones? Which one is better? Why?

 

In smartphones, there are various types of displays available in the market. Three of the most common types are PMOLED, AMOLED, and TFT displays. Each of these displays has its own set of advantages and disadvantages that distinguish them from one another. In this article, we will explore the differences between these displays and determine which one is better.

 

PMOLED

 

PMOLED stands for Passive Matrix Organic Light Emitting Diode display. It is a basic type of OLED display that uses a simple matrix of pixels to light up. The pixels in a PMOLED display are arranged in rows and columns, and each pixel is individually controlled by its own transistor. PMOLED displays are relatively inexpensive to manufacture, making them a cost-effective option for smaller devices like smartwatches and fitness trackers.

However, PMOLED displays have some drawbacks. They are not as bright as other OLED displays and have relatively low resolutions. PMOLED displays also consume more power when displaying bright colors.

AMOLED

 

AMOLED stands for Active Matrix Organic Light Emitting Diode display. It is a more advanced type of OLED display that uses a backplane of thin-film transistors (TFTs) to control each pixel individually. The backlighting in an AMOLED display is turned off on a per-pixel basis, allowing for deeper blacks and better contrast. AMOLED displays are known for their vibrant colors, high resolutions, and excellent viewing angles.

AMOLED displays are typically more expensive to manufacture than PMOLED displays, but this cost is often offset by their superior performance. They are commonly found in high-end smartphones and tablets.

TFT

 

TFT stands for Thin-Film Transistor display. It is a type of LCD display that uses a TFT active matrix to control each pixel. TFT displays are often used in smartphones because they are relatively inexpensive to manufacture and have excellent color reproduction and high resolutions.

However, TFT displays have some drawbacks. They consume more power than OLED displays, have lower contrast ratios, and can suffer from limited viewing angles. They also have a slower response time, which can result in motion blur during fast-moving scenes.

Which one is better?

 

When it comes to PMOLED, AMOLED, and TFT displays in smartphones, there is no clear winner. Each type of display has its own set of advantages and disadvantages, and the best choice depends on the user's needs.

 

PMOLED displays are a cost-effective option for smaller devices like smartwatches and fitness trackers. They consume less power than AMOLED displays and are easy to manufacture. However, they have lower resolutions and are not as bright as other OLED displays.

 

AMOLED displays are known for their vibrant colors, high resolutions, and excellent viewing angles. They offer superior performance compared to PMOLED displays but are more expensive to manufacture. They are commonly found in high-end smartphones and tablets.

 

TFT displays are often used in mid-range smartphones due to their relatively low cost and excellent color reproduction. However, they consume more power than OLED displays, have lower contrast ratios, and can suffer from limited viewing angles.

 

In conclusion, while AMOLED displays are generally considered to be superior to PMOLED and TFT displays, the choice of display type ultimately depends on the user's individual needs and preferences. Each type of display has its own strengths and weaknesses, and users should choose the one that best suits their requirements.
