Why are manufacturers using AMOLED Screen Display more frequently? What are the pros and cons of AMOLED Display Screens? And what is concealed beneath the word AMOLED? Let’s find the answers to your questions.
A few years ago, the mere presence of an AMOLED display on a smartphone indicated that it was a flagship or near-flagship device. But as technologies evolved and became more affordable, this type of display became increasingly popular, and it is now simple to find inexpensive devices with AMOLED.
What is an AMOLED Screen Display?
Let’s begin by establishing that the terms AMOLED, Super AMOLED, P-OLED, and other OLEDs all refer to the same technology with minimal distinctions when discussing smartphones.
Such matrices always employ organic LEDs, which do not require backlighting, unlike IPS and other types of LCD panels. Each display pixel can emit light independently when an electric current travels through it. And in this aspect of AMOLED, all the benefits and drawbacks of this screen type reside.
Advantages of AMOLED Display
Beautiful Contrast: We have previously stated that AMOLED screen pixels can light up when a current travel through them. Therefore, the black colour of such matrices corresponds to a pixel entirely off.
And what could be even darker than a pixel that emits no light? IPS panels cannot achieve AMOLED’s profound blacks due to their continual glow, even when displaying a black tint.
Wide View Angle: Besides having the highest contrast and the deepest black colour, AMOLED displays have the widest viewing angles. Even if you view such a screen from a very acute angle, you won’t observe any significant colour distortion or loss of luminance.
Always on Display: When an IPS display is turned on, its full backlighting is activated, regardless of the image displayed. AMOLED does not have this issue. The ability of each pixel of the matrix to illuminate independently enables you to “turn on” each pixel individually, significantly reducing the screen’s overall energy consumption.
For instance, if you display the clock numbers on a black screen, only the pixels that display the current time will consume power, while the remaining LEDs will remain off. Thus operates the Always On Display function.
Backlight: The backlight of IPS displays cannot be precisely homogeneous because they employ individual LEDs, the light transmitted under the entire matrix employing a unique light-conducting film.
Consequently, the illumination appears more intense near the LEDs and progressively decreases as it travels through the film. In AMOLED, each pixel is illuminated. Such a matrix does not necessitate an additional illumination layer, and uniformity issues do not arise by definition.
Disadvantages of AMOLED Displays
Screen Flickering: The primary disadvantage of any AMOLED display is that it flickers when the luminance is decreased. This effect may be more substantial or lesser depending on the cost and quality of the display, but it will only dissipate partially.
Display Burnout: The luminosity of AMOLED displays depends on the pixels’ flickering speed: the brighter the display, the quicker the pixels pulse, and the slower the flickering speed. When the pulsation rate falls below a certain threshold, some users become uncomfortable and experience eye fatigue.
The problem of burn-in is notably prevalent in previous generations of AMOLED displays. It is less prevalent now, but it has not entirely disappeared. If a static image with high luminance is displayed on the screen for an extended time, it will be permanently “imprinted” on the AMOLED display.
Price: The price of AMOLED displays is progressively declining, which explains their emergence in inexpensive handsets, but it is still more expensive than comparable IPS matrices. For the average consumer, this translates to a higher price for an AMOLED smartphone and a replacement display that is considerably costlier.
AMOLED displays have numerous benefits and are favoured by many users due to their excellent contrast with deep black colour, wide viewing angles, uniform illumination, and the ability to utilize the highly convenient Always On Display function. However, asserting that they share the same advantages is incorrect. When its luminance is decreased, flickering is the primary flaw of any AMOLED matrix, which some users may observe.
