Types of Displays in Mobile Phones

While buying a mobile phone we might have heard these words – IPS LCD display, TFT LCD display, OLED display, Super AMOLED display, etc. We often get confused as to which is the best. So, let us explain each of the displays. Displays are mainly categorized into three types –

  1. LCD (Liquid Crystal Display)
  2. LED (Light Emitting Diode)
  3. Retina

These are explained as follows.

1. LCD (Liquid Crystal Display)

LCD means Liquid crystal display. In the LCD display, there is a light in the background of pixels which is called a backlight that provides light to the pixels for projecting the content. If there is no light in the background we could not able to see the content which is displayed on the screen. There are a few types of LCD panels. In the LCD panel, we have CCFL backlighting which means Cold Cathode Fluorescent Lamp. These are explained as follows.

As for mobile displays, we mostly see these three displays in LCD –

2. LED (Light Emitting Diode)

In the place of CCFL, we use LEDs. In LCD display we use CCFL as backlighting and in the LED display we use LED bulbs as backlighting.

There are so many types of LED displays. Generally, we may see these two displays in the flagship category mobiles. they are, OLED and AMOLED displays. Technology is almost the same, but OLED is developed by a company named LG, and AMOLED is developed by a company called Samsung.

  1. AMOLED (Active-Matrix Organic Light Emitting Diode) – This technology completely belongs to Samsung. They took patients also. The main function of the AMOLED display is the individual pixel act as an LED bulb. Which means they do not require backlighting. This technology helps in power saving and projecting true black colors. The pixels stop projecting light when the video has black color. The black portion in the video is projected like a true black color. So, it saves power when the content has black color. And we could enjoy true black colors. The main difference between AMOLED and Super AMOLED is like IPS LCD and SLCD. AMOLED has a gap between the glass and touch sensor. Super AMOLED has no gap between the glass and touch sensor (negligible gap).
  2. OLED (Organic Light Emitting Diode) – This technology belongs to LG. LG took patents on the OLED panel. It is like the LGs trademark. This display is also like an AMOLED display. OLED has a series of organic thin-film between two conductors. When the current is applied, light is emitted. These are more efficient than LCD displays.

3. Retina Display

Retina display is the trademark of the company named APPLE. Actually, the retina display is an IPS LCD display only. APPLE modified the IPS LCD display and renamed it. In retina display, we can more PPI (Pixel per inch) than IPS LCD displays. It is not a separate technology. It is a modification of the IPS LCD display. We can see retina displays in Apple mobiles.

Which is the best display?

Obviously, AMOLED and OLEDs are the best displays in the world.
