What is an AMOLED DISPLAY | How it’s working pro’s and con’s | Where it can be use

Amoled Display

AMOLED technology was probably a few years ago on a high-end smartphone promising a bigger, more color-rich display. Now you’re hearing about AMOLED laptop screens and PC monitors. But what is AMOLED? How does it make screen viewing a better experience?

Benefits or advantages of AMOLED display screen

Following are the benefits or advantages of AMOLED display screen:

➨It offers more colors and true color re-production due to direct pixel to pixel illumination control. Moreover it offers greater contrast ratios.

➨It consumes less power especially while displaying dark screens.

➨AMOLED display screens are lighter and thinner than ordinary display screens.

➨It offers wider viewing angles which is about 170 degrees.

➨It offers super flexibility.

➨These screens are brighter than LED screens.

➨It is easy to produce and can be made in big sizes for example, laptop and PC monitor screens.

➨It resists instant pressure and it is brakeless when it falls from certain height.

AMOLED is a display technology that is used on many screens. Most of them are usually found on smartphones, so if you have been looking for a smartphone, from brands like Samsung or Google Pixel, you might have stumbled on some that brag about having AMOLED displays

LCD displays explained

LCD stands for Liquid Crystal Display and reproduces colors quite differently from AMOLED. Rather than using individual light-emitting components, LCD displays rely on a backlight as the sole light source. Although multiple backlights can be used across a display for local dimming and to help save on power consumption, this is more of a requirement in larger TVs.

Scientifically speaking, there’s no individual white light wavelength. White light is a mixture of all other visible colors in the spectrum. Therefore, LCD backlights have to 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.

Pros & Cons  LCD and AMOLED displays are fantastic technologies that continue to push forward the standard for Mobile Displays.Considering that the AMOLED display as we know it in Smart Phones is only a few years old, it is exciting to see what kind of innovations we can look forward to in the future.

LCD Pros

• Bright whites – LED backlights push lots of light through the pixels to make it easier to read in bright light

• Accurate True to Life Colors – This can vary from one to the other, however as a general rule, LCD Screens have colors that more accurately reflect those of objects here in the real world versus through a viewfinder.

• Reliable – LCD technology has been around for a while, and the technology is well into the refinement stage of development.

• Great Viewing Angles – Most high quality Phone LCD displays use IPS technology to offer 178 degrees of view without any color shifting or color distortion.

• Inexpensive – LCD Technology has been around for quite some time, and with that, the manufacturing process has been perfected in the mobile sphere, allowing massive volumes of screens to be produced at very cost effective rates.

LCD Cons

• LCDs cannot achieve deep blacks – The presence of an always on backlight to illuminate a screen regardless of how much of the screen is black means that it will never get as dark as an AMOLED screen can.

• LCDs cannot be made flexible – The Galaxy Note Edge turned heads in 2014 when Samsung unveiled a curved AMOLED display. LCDs are rigid and cannot be bent or molded into a curved design, limiting the form factors it can fit into.

• Thickness – Because the LCD also requires a backlight behind it, the screen will always take up more internal volume of a phone, limiting how thin and light designs can be.

AMOLED Pros

• Amoled Screens have the most vivid colors – Ever want your movies or pictures to pop like they haven’t before? AMOLED screens can make that happen with amazing contrast ratios(distance in color from darkest to lightest).

• True Black can be truly achieved – Because no backlight assembly is needed, the display can power off pixels that are to display the black portions of an image, meaning the black is as dark as it can be. That means looking at a Zebra uses less energy than a polar bear on your Galaxy.

• Energy Efficiency – Because the display can individually light pixels, and likewise leave some pixels turned off entirely, this means the screen can achieve levels of power efficiency rarely seen on smartphone displays, leading to better battery life.

• Flexible, Curvable, Adaptable – Flexible AMOLED Displays are present in the Samsung Galaxy, the Galaxy Gear uses a curved display, and nearly every other smart wearable uses a circular AMOLED display. LCD’s would not be able to work in any of these scenarios. AMOLED is the screen tech for wearables(Apple Watch, Moto, Gear S etc.)

AMOLED Cons

• Cost– Right now, the typical cost on the repair market for an AMOLED screen is double that of a comparable LCD (in some cases it can be even more). This is tied to higher manufacturing costs, and the fact that the technology is younger, and less refined compared to their LCD counterparts.

• Less Durable – Much like old strings of Christmas lights, if a single pixel is damaged, it can cause the entire screen to stop displaying altogether. In many cases, the AMOLED display will crack or break before the glass on top of it does.

• Burn in – This is an issue that was present on old Plasma Televisions. Over time the pixels can get “stuck” showing a specific image or color, meaning that over time as the screen gets older, it can show a shadow of an icon. A good way to mitigate this is to move your icons around every once in a while.
