Difference between LCD and Amoled | what is best ?

Right now mobile comes with two type of difference display One is Amoled and Second is LCD .So here I have mention some brief information about both display panels. LCD. Stands for “Liquid Crystal Display.” LCD is a flat panel display technology and AMOLED is an ‘active-matrix organic light-emitting diode’. It adds a layer of semiconducting film behind the OLED panel which allows it to more quickly activate each pixel. LCD displays rely on a backlight as the sole light source, positioned from the side or back. When AMOLED displays are made up of a matrix of Organic LED (OLED) “pixels” which create light.

Difference between LCD and Amoled

Round 1: Contrast

LCD displays often look more dull and muted compared to AMOLED. Because they use a single screen-wide backlight, they cannot produce “true black”, but are capable of producing more realistic on-screen colours than AMOLED.
AMOLED displays can produce deeper blacks compared with LCD by switching off individual “pixel” lights. A black AMOLED screen pixels produce no light whatsoever, meaning you technically get an “infinite” contrast ratio.

Winner is AMOLED!

Round 2: Light Output

Because of its screen-wide backlight, screens using LCD display technology can be much brighter.
For the same reasons, current LCD screens also tend to have whiter whites.So LED have this advantage much brighter. Some disadvantage also
AMOLED cannot produce a full screen with as much brightness as LCD as its light is produced from individual pixels which lack the power of a screen-wide LCD backlight. These displays may also be hard to view in sunlight because of their rela­tive lack of brightness.


Round 3: Viewing Angles

A big downside of LCD screens is a change in picture quality if you’re viewing the screen from an angle. However, a lot of moder n LCD screens use IPS (in-plane switching) providing much better colour performance and dramatically improved angled viewing.
AMOLED enjoys good display performance even with off-centre viewing angles due to the fact that its light “pixels” are thin and close to the display surface – OLED panels also emit their own light, so aren’t prone to changes in picture quality when viewing angle changes

Winner is AMOLED!

Round 4: Energy Consumption

The display on phones or tablets tends to account for the vast majority of their power consumption. When LCD-based devices are on, the entire backlight is also on, so keeping brightness at the lowest acceptable level is essential to optimise battery life.
AMOLED pixels are responsible for producing light, so a black pixel is ‘off’, and doesn’t use any power.
However to make the most of this feature, apps must support displaying true black – anything else will activate the pixels and consume power.


Summary of this comparison

ContrastAMOLEDIndividual light pixels that can turn off for true black
LightLCDBrighter Light Output Due to Backlight
Viewing AnglesAMOLEDAMOLED light pixel thin and close to the screen surface
Energy UseAMOLEDBlack(Off)c Pixels don’t use any power

So here you can see AMOLED is clear winner but other side AMOLED price to high then LCD so phone with AMOLED price is little bit higher then LCD Display phone .
