What is AMOLED?
AMOLED is Active Matrix Organic Light Emitting Diode. Its core part is still LED.It’s very common to see LED in daily life.There are many small size of LEDs on the screen,and they are divided into three sub-pixels of red, green and blue. Then different colors are combined, and the arrangement of sub-pixels will directly affect the whole display effect.The “O” of AMOLED stands for Organic, which means a series of organic thin film materials are used between the positive and negative electrodes to achieve the purpose of luminescence.

The advantage of OLED screens is pixels can be highly controlled, each of them are independently controlled to achieve better contrast ratio. In addition, turning off unnecessary pixels when show the picture,also could get lower power consumption.Further,simple structure and good transparency,which are conducive to OLED achieve higher brightness and wider viewing angle.

Contrasting with LCD,OLED screen can be produced as more thin,it’s ideal for mobile devices like mobile phones.Along with the mature technology of flexible plastic substrates to replace hard backlight OLED will have great advantage in flexible screen,which makes the devices shapes can be customized in the future.

What is LCD?
LCD, is Liquid Crystal displays, its luminous mode is different from AMOLED.Unlike AMOLED,all pixels on an LCD screen rely on a uniform backlight layer.Some large LCD screens for TVs, also will use multiple light sources to reduce power consumption.As there is no corresponding wavelength of white light and this kind of white light is just a mixture light from other colors,LCD screen need to produce white through the combination with backlight and phosphor powder.

The white light is generated by the backlight layer and convert the fully polarized light into linearly polarized light at the first polarization layer, then through the liquid crystal molecules layer, according to the different voltages, normally liquid crystal molecules present different torsion angle, and then through the red, green and blue filters generate different colors, and then by the second polarization layer (perpendicular to the first layer), realize the control of light intensity, ultimately realize different color requirements through the light intensity combination of three different colors of red, green and blue.

LCD vs AMOLED

LCD
AMOLED
The obvious difference between AMOLED and LCD screen is that AMOLED has wider color gamut.The more colors are displayed, the more delicate the picture will be.In addition, AMOLED screens are highly saturated when showing blue and green, in early times,AMOLED screens were often criticized for inaccurate color and excessive color.LCD overcompensate red and suppress green,and its color gamut is smaller, but are actually closer to the standard RGB gamut used in video and image editing.
The color level is the other very important evaluation index. According to the test data, the color level performance of AMOLED screen is better, especially when it is really white, while LCD screen is usually a little blue or green. Considering that LCD screens usually use a blue backlight, it is not a surprising result.
In addition, weight is one of LCD disadvantages, the other one is using backlight layer,resulting light-leaking and low contrast ratio. Short lifetime is the problem of AMOLED, which can lead to color drift with the using time increased, while LCD don't.

The Characteristics Of AMOLED

Wide Color Gamut
Wide range of gamut is more colors can be showed on the screen,industry standards include NTSC gamut values, sRGB gamut values, and Adobe RGB gamut values.In terms of sRGB color gamut, iPad Air can show 96% of sRGB range.The Super AMOLED screen show color gamut is close to 100% NTSC,has exceeded the sRGB category,closer to the higher Adobe RGB standard.
High Contrast Ratio
Compared with traditional TFT screens, the black color is thick and pure black which is showed by AMOLED, TFT is close to dark gray. AMOLED white is pure white, good to achieve a more transparent effect.
Ultra-Thin Design
AMOLED are thinner than LCD screens. LCD contain backlight,color filters, backlight modules and liquid crystal materials,but AMOLED do not need those parts because of its self-luminous mechanism. Integrated touch technology also promote AMOLED more thinner and lighter.
Sunlight Readability
It's possible to see maps or addresses on your phone under bright light. Sunlight readability is proportional to chroma multiply by brightness, while OLED's chroma is 1.7 times than LCD.The AMOLED screen has good sunlight readability, making colors to be clear under bright sunlight, providing a better perspective for outdoor reading.
Low Power Consumption
AMOLED is significantly use less power contrasting with traditional LCD because each pixel of AMOLED can be independently controlled without constant backlight, saving energy for the device. Even if you watch video or enjoy multimedia, there is no significant loss of battery life.

Technical Advantages

01
AMOLED screens are very thin, and can be integrated in the screen touch layer, It is more easy to make ultra-thin machines.
02
High resolution AMOLED use PenTile to make the picture look brighter.
03
Both AMOLED and Super AMOLED have a wide color range.
04
AMOLED has a certain flexibility,LCD screens are easy to damage than glass substrates.
05
AMOLED is self-luminous, when showing black, Individual pixels do not work,when dark color,it is Low power consumption.So AMOLED is energy-saving in the dark color status.Contrasting with traditional LCD,its contrast ratio is better as hundreds of times,and would not light leak.
