AMOLED vs LCD Difference Explained.
                     AMOLED VS LCD: 
DIFFERENCE EXPLAINED
INTRODUC
TION
Mobile display technology is firmly 
split into two camps, the AMOLED 
and LCD crowds. There are also 
phones sporting OLED branding, 
which is essentially the same tech 
as AMOLED.

AMOLED 
AND LCD
AMOLED and LCD are based on 
quite different underlying 
technologies, leading 
manufacturers to tout several 
different benefits depending on 
which display type they’ve opted 
for.

AMOLED 
TECHNOLOGY
• It’s hidden in the name, but the 
key component in these display 
types is a Light Emitting Diode 
(LED). 
• In a display panel these are 
shrunk down dramatically and 
arranged in red, green and blue 
clusters to create an individual 
pixel that can reproduce white 
light and various colors, 
including red, green, and blue.

ORGANIC 
MATERIAL
• The O part in OLED stands for 
organic. Simply put, there are a 
series of thin organic material 
films placed between two 
conductors in each LED, which is 
then used to produce light when 
a current is applied.

ACTIVE 
MATRIX
• The AM part in AMOLED stands in 
for Active Matrix, rather than a 
passive matrix technology. This 
tells us how each little OLED is 
controlled.

MAJOR 
BENEFITS
• The major benefits from OLED 
type displays comes from the 
high level of control that can be 
exerted over each pixel. 
• Pixels can be switched 
completely off, allowing for deep 
blacks and a high contrast ratio.

LCD 
TECHNOLOGY
• LCD stands for Liquid Crystal 
Display and reproduces colors 
quite differently to AMOLED. 
• Rather than using individual light 
emitting components, LCD 
displays rely on a backlight as 
the sole light source.

LCD 
BACKLIGHTS
• LCD backlights must create a 
pseudo white light as efficiently 
as possible, which can then be 
filtered into different colors in the 
liquid crystal element. 
• Most LCDs rely on a blue LED 
backlight which is filtered 
through a yellow phosphor 
coating, producing a pseudo 
white light.

OLED 
DISPLAYS
• OLED displays are known for 
additional green and blue 
saturation, as these tend to be 
the most powerful colors in the 
sub-pixel arrangement and very 
little green is required for white 
light.

LCD 
DISPLAYS
• LCDs typically tend to 
overcompensate further into the 
reds, with more subdued greens. 
Although not possessing quite 
such a wide gamut, LCD displays 
typically offer a very close match 
to the Standard FBG color gamut 
profile used by image and video 
media.
