The screen is an important part of a device, whether it’s a smartphone, tablet, laptop, or even AIO. Currently there are two most popular screen technologies, namely AMOLED and IPS LCD. So what’s the difference between the two, and which is better, AMOLED screen or IPS LCD? For those of you who are curious, let’s look at the following reviews:
• IPS LCD
LCD (Liquid Crystal Display) has existed for a long time and is still widely used in smartphones, tablets, TVs, and the majority of computer monitors. In essence, LCD uses liquid crystals, where one LCD pixel is made of one liquid crystal as a point of light. Behind this liquid crystal arrangement there is a backlight which is the light source. The light that passes through the liquid crystal is then polarized, controlled by horizontal and vertical filters on the side of the crystal arrangement, so that some colors will be transmitted and other colors will be filtered out.
The most widely used LCD technology today is IPS (In-Plane Switching) LCD. IPS LCD screens have various advantages and disadvantages, including:
Advantages of IPS LCD
a) Production costs are cheaper than AMOLED
b) Have a good color gamut
c) Produces a more natural color appearance
d) The color is brighter when under direct sunlight
e) Does not have a burn-in effect like AMOLED, so it can last a long time.
f) The resulting image is sharper
Disadvantages of IPS LCD
a) Color contrast ratio is not as strong as AMOLED (Black is not 100% black, white is not 100% white)
b) More energy consuming than AMOLED
c) Refresh rate and response time is lower than AMOLED
d) Because it is equipped with backlight, IPS LCD is thicker than AMOLED
• AMOLED
AMOLED (Active Matrix Organic Light-Emitting Diode) is a newer technology than IPS LCD. In essence AMOLED uses anode and cathode to flow electrons through a very thin film layer. Brightness is determined by the strength of the electrons flowing, while the color is governed by the red, green, and blue emitting diodes embedded in the screen.
AMOLED technology that is often used today is Super AMOLED. Super AMOLED screens have various advantages and disadvantages, including:
AMOLED advantages
a) Has a higher contrast ratio than IPS LCD
b) More efficient in power consumption, even up to 10x more than IPS Display
c) Can update the pixel color independently, in contrast to IPS which updates the entire pixel every time there is a color change. The result is AMOLED has a faster FPS and response time.
d) Since each pixel is an independent RGB LED, to display black color the screen will turn off the pixel, so the black color is really black, and this cannot be achieved by IPS LCD screen.
e) White color is also better represented by AMOLED than IPS LCD which tends to be bluish.
Disadvantages of AMOLED
a) It is prone to screen burn-in, so if for a long time you often use the WhatsApp application, for example, the WhatsApp icon/design will be left on the screen.
b) Production costs are much more expensive than IPS LCD, especially for large screens. So devices with AMOLED screens are often expensive too.
c) If you use black wallpapers and themes, AMOLED is indeed more battery efficient. But if on the other hand, you use white or bright wallpapers and themes, AMOLED can also be more wasteful in power usage than IPS LCD. So whether or not the AMOLED screen is wasteful depends on how you use it.
• AMOLED vs IPS LCD, Which is Better?
From the comparison above, it is clear that both AMOLED and IPS LCD have their own advantages and disadvantages. You can decide for yourself which one is the best according to your individual needs.
For example, the average AMOLED screen smartphone has a higher price range than the IPS LCD screen smartphone because the AMOLED screen itself is more expensive than the IPS LCD. (Except for the iPhone, which even though until now still uses an IPS LCD screen, but the selling price is priced very high by Apple). So if your budget is limited, you can choose an IPS LCD screen smartphone.
Or if you want to maximize the durability of the smartphone battery, then you can choose an AMOLED screen and then use a black dominant theme and a black dominant wallpaper, then the power usage by the AMOLED screen will be much more efficient than if you do it on an IPS LCD screen that wants black or not bright will impact any difference in power usage.
Another example if you are a photo editor or video editor, you can choose a laptop / AIO with an IPS LCD screen because it gives a natural color display and is closer to the original, rather than an AMOLED screen which provides colors with higher saturation.
So both AMOLED and IPS LCD both have their respective advantages and disadvantages, and each can be better than the other, depending on the needs and desired needs.
