Types of Displays Explained with Pros and Cons!

There are different kinds of displays in the market available for mobiles phones, TVs, and Laptops. It is important to know about them before buying one. In this post, I will talk about some of the displays currently available in the market that help you decide which one to go for.

Types Of smartphone Displays:

1. TFT-LCD – TFT-LCD stands for Thin Film Transistor LCD (Liquid Crystal display). It is an improvement in the LCD Displays available before. Each pixel in the TFT-LCD Display has its own transistor on the glass itself, which offers more control over the images and color that it renders. This display is found on lower end smartphones, TVs and Monitors.
   
   
   Pros:- Better Image quality, higher Resolution compared with earlier generation of LCD, low Cost, Performs better in direct sunlight.
   
   
   Cons:- Poor viewing angle, consumes more power and hence are not battery friendly.
   
   
2. IPS-LCD – IPS-LCD stands for In-plane switching LCD. It is an improvement over TFT-LCD displays. It delivers better color reproduction and wider viewing angles. It does this by using two transistor for each pixel combined with more powerful backlight. It has a better viewing angle, which is an improvement over TFT.
   
   
   Pros – Wider viewing angle compared to TFT, Lower power consumption, Brilliant picture display, better color reproduction.
   
   
   Cons – Slightly costlier than TFT and hence found on mid-range smartphones.
   
   
3. OLED- OLED stands for an Organic light emitting diode. OLED technology is recently used in mobiles and computers. In OLED displays, a thin carbon film is sandwiched between two conducting layers of anode and cathode. This whole portion is sandwiched between two glass plates. When an electric pulse is applied between two conducting sheets; electro-luminescent light is produced directly from the carbon switched between them. As opposed to LCD displays, which are always backlit, OLED displays are switched off until individual pixels are electrified.
   
   
   Pros:- Faster response times, wider viewing angles, higher brightness, lightweight design, brilliant color reproduction, better battery life.
   
   
   Cons:- does not perform better in direct sunlight due to absence of backlight.
   
   
4. AMOLED- Active matrix OLED is a type of OLED displays that are specifically designed for smartphones. Active matrix means each pixel is attached to a transistor and capacitor individually. This way, when a row and column is activated to access a pixel, the capacitor at the correct pixel can retain its charge in between refresh cycle, allowing for faster and more precise control.
   
   
   Pros:- Higher refresh rate, contrast ratios are greater than LCD screens, Thinner screens.
   
   
   Cons:- Not quite visible in direct sunlight (same as OLED).
   
   
5. Super AMOLED- Super AMOLED is an advanced version of AMOLED displays developed by Samsung. Super AMOLED displays have capacitive touchscreen right into the display, instead of having a separate layer on the top of the display. This makes them thinnest in the market.
   
   
   Pros:- Higher contrast, thinner, more Vibrant color display, more sensitive to touch, higher refresh rate.
   
   
   Cons:- shortened battery life when using vibrant colors.
   
   

This was just an overview of displays present in the market. I will try to explain the working of LCD and LED in a separate post. Please, comment below if you come up with any suggestion. Finally, thank you.
