Display type – definition


Today’s smartphones employ a variety of display/panel kinds.


  • LCD (Liquid Crystal Display)
  • IPS-LCD (In-Plane Switching Liquid Crystal Display)
  • OLED (Organic Light-Emitting Diode)
  • AMOLED (Active-Matrix Organic Light-Emitting Diode)

We go to great efforts when evaluating screens throughout our review process in order to determine a display’s quality by measuring Contrast Ratio, Color Calibration, Brightness, and Sunshine Legibility. The screen, when paired with the touch element, is “the” key part of the user interface.


A matrix of liquid crystals makes up LCD (Liquid Crystal Display) screens. Liquid crystal displays require some sort of backlight because they cannot produce light on their own. LCD screens may therefore be quite apparent in direct sunlight.

Our tests demonstrate the IPS-LCD matrix for the iPhone 8 Plus in great detail.

Due to the design of the LCDs itself, IPS-LCDs provide a wider viewing angle and greater colour reproduction than non-IPS-LCDs. For mid-range to high-end phones, this display style has grown to be ubiquitous.


OLED & AMOLED utilizes ‘organic’ LEDs which emits light and in the majority of cases does away with the need for the back-light of an LCD display resulting in a potentially thinner panel. It offers greater contrast ratio and less washed-out “blacks,” and it is quite noticeable in low light.

When magnified, the differences between panel types are clear

Compared to LCDs, whose backlight is always on, they use less energy. With an OLED/AMOLED display, a pixel that seems to be “black” is really off.
