If you want to experience a more pleasant screen visual experience, you should choose a device that offers an OLED panel.
OLED panels have a myriad of advantages, such as higher power efficiency, a wider color range, and unmatched contrast ratios.
Find sales of phones with Super AMOLED screens here.
OLED screens also have several choices, namely AMOLED, Super AMOLED, Dynamic AMOLED, and also LTPO AMOLED.
So, each type of OLED panel has unique and diverse characteristics.
Here are the different types of OLED, AMOLED, Super AMOLED, Dynamic AMOLED, and LTPO AMOLED screens:
1.OLEDOLED stands for Organic Light Emitting Diode.
Unlike IPS LCD panels which require a backlight as a light source, the pixels on an OLED panel can emit their own light when powered.
The OLED panel itself consists of a layer of organic semiconductor material located between two electrodes.
OLED can also be interpreted as an organic light diode that transforms as a semiconductor to emit light.
Thanks to its ability to emit light organically without the aid of a backlight, OLED panels are also considered more energy efficient than IPS LCDs.
The advantages of OLED panels also lie in their production costs, which tend to be cheaper than AMOLED or other types of OLED derivatives.
OLED panels provide wider viewing angles than LCDs, are flexible, and are capable of displaying true blacks resulting in high contrast ratios.
Despite its advantages, OLED panels have the potential to experience burn-in or image retention.
When displaying static visual elements in the same place for a long duration, they will disappear over time and permanently imprint them on the screen.
2. AMOLEDCompared to OLED, you can enjoy the advantages of AMOLED, such as a longer lifetime, more resistance to extreme weather and higher levels of brightness or luminance.
Just like OLED, AMOLED also doesn't need a backlight so it can maintain battery life so it doesn't run out quickly.
AMOLED contrast ratio is also very good, being able to reach the lowest luminance level at 0 nit (true black).
3.Super AMOLEDIf AMOLED is an enhanced form of OLED, then Super AMOLED can be said to be an enhanced form of AMOLED.
Just like regular AMOLED, Super AMOLED can display an infinite contrast ratio because there is no backlight layer in it.
So each pixel displays its own light.
When there is no power (when the screen displays black bars), then the pixels really don't light up.
That's why cellphones with IPS LCD or TN TFT panels cannot implement the AOD (Always On Display) feature.
Compared to regular AMOLED, you can expect a 20 percent increase in terms of power consumption and screen brightness.
Super AMOLED is also allegedly able to reduce the reflection of sunlight by up to 80 percent compared to AMOLED, as claimed by Samsung.
Super AMOLED is the tier version that combines the touch sensor with the screen itself instead of being layered on top of it.
Therefore, Super AMOLED is also thinner when compared to regular OLED panels.
4. Dynamic AMOLEDThe Dynamic AMOLED panel is an improvement over Super AMOLED.
All the properties of Super AMOLED are also owned by this Dynamic AMOLED.
The difference is that SAMSUNG provides additional HDR10 + certification so that the color levels, contrast and brightness are even better.
The Dynamic AMOLED panel also supports the DCI-P3 color gamut so that the screen will always display striking colors at any brightness level.
As for other advantages, Dynamic AMOLED tends to produce fewer blue light emissions, so the user's eyes don't get tired easily.
Dynamic AMOLED also often has an extra "2X" behind it, indicating that the screen has a refresh rate of double that of 120 Hz.
Apart from Dynamic AMOLED, SAMSUNG also released another panel variant called E4 AMOLED.
In short, this is the next generation of Super AMOLED which was released in 2020.
Like Dynamic AMOLED, E4 AMOLED also supports HDR10+ certification and DCI-P3 color gamut.
E4 AMOLED has also received a Display Mate A + certificate, carries a delta E color accuracy below 1, supports a refresh rate of 120 Hz and also a touch sampling rate of 240 Hz.
5. LTPO AMOLEDLTPO AMOLED is a technology panel manufactured by Apple. (oppo.com)
LTPO AMOLED is a technology panel produced by Apple.
LTPO stands for Low Temperature Polycrystalline Oxid which is specifically designed to be able to set the lowest possible refresh rate when no activity is detected on the screen.
LTPO AMOLED was originally used by Apple for its smartwatch product, which was named the Apple Watch.
Smartwatches need the highest possible power efficiency in order to last a long time without overcharging.
With the use of LTPO AMOLED, the refresh rate on the Apple Watch screen can be lowered to 1 Hz when displaying a static image, and back to 60 Hz when the screen is used (swipe).
Thus, the battery can last longer than it should.
As technology develops, LTPO AMOLED is also used on high-end smartphones, such as Oppo Find X3 Pro, Oppo Find X5 Pro, SAMSUNG Galaxy Z Flip3, and many more.
The drawback is that the production of these display panels is very expensive so only flagship phones have them 276
