The screen is an important part of the device, whether it is a smartphone, tablet, laptop or monoblock. Two display technologies are currently popular: AMOLED and IPS LCD. Let’s see what is the difference between them.

IPS

LCD display with IPS technology is widely used in smartphones, tablets, TVs and most computer monitors. The technology is based on the use of liquid crystals, where one pixel consists of one liquid crystal.

A backlight behind the liquid crystal system is used as a light source. Light passing through the crystal is polarized by horizontal and vertical filters. Thus, some colors are transmitted, while others are filtered out.

Advantages and disadvantages of IPS matrices:

AMOLED

The technology uses two electrodes, one of which is transparent. Between them are layers of organic semiconductors. When current flows through the electrodes, the semiconductor layers glow, and the strength of the current controls the brightness of this glow.

Each OLED is independent, so a single pixel serves as its own light source. To display black, the screen turns off the corresponding pixels completely.

Advantages and disadvantages of AMOLED displays:

Other Technology Differences

Since the display technologies in IPS and AMOLED are fundamentally different, the technical characteristics of the panels also differ.

energy efficiency

In AMOLED, images with predominantly bright colors consume 0.7 watts, while a picture with predominantly dark hues consumes about 0.3 watts.

IPS panels deliver a constant output of 0.35W, no matter what is displayed on the screen.

Response and viewing angles

The response time of a typical AMOLED panel is 1 ms, for IPS it is multiple times higher: from 5 to 8 ms. This affects the smoothness of the picture and the speed of interaction (especially in video games).

As for viewing angles, AMOLED also has a slight advantage here. However, the difference can only be seen with a detailed comparison – the average user will not notice it.

The viewing angle is similar in both versions: technologies are able to maintain decent off-axis image quality. For smartphones and tablets, this means that devices can be held at different angles and at any eye level. In televisions and computer monitors, a wide viewing angle enhances the visual experience.

Life time

One of the reasons why IPS technology, despite the shortcomings described above, is considered more advanced than the AMOLED matrix.

AMOLED panels used in premium smartphones show signs of degradation after 2 years. The display technology is designed so that blues and whites fade faster than reds and greens. Over time, the decrease in brightness, color change and fading become too noticeable.

Both technologies have a right to exist, but AMOLED is not the best option for use in work laptop or desktop monitors. The images on these devices are often static. Reading documents, browsing websites practically do not require changing the picture: the white background dominates. For an AMOLED panel, this will speed up pixel burn-in.

In addition, organic AMOLED materials are susceptible to water damage, unlike the inorganic crystals used in IPS panels. Submerging an AMOLED panel in water will definitely break it – no chance.

Choosing the Right Display

Price category

The average smartphone with an AMOLED screen is more expensive than a smartphone with an IPS screen because the prime cost of the former is higher. iPhone is an exception to the rule, but there is a different pricing policy. The use of IPS technology does not reduce the cost of Apple products.

For the rest – with a limited budget, preference should be given to IPS-screens.

Professional tasks

Photo and video editors, graphic designers should choose a monitor with an IPS matrix, because the color palette of the display is closer to the original. AMOLED screens over-saturate hues.

But if security issues come to the fore, then you need to remember: at present, you can install an integrated fingerprint scanner only on AMOLED displays.

Leisure

Bright and saturated colors, wide viewing angle and deep blacks – all this makes AMOLED panels an ideal option for multimedia entertainment: watching videos and photos.

Manufacturers of some AMOLED panels have, of course, introduced a number of innovative solutions to increase the brightness of displays. In particular, the gaps between the matrix layers were reduced and a special coating was applied to reduce external reflection. As a result, the difference has become less noticeable, but still it is.

AMOLED technology delivers smooth moving images to reduce eye fatigue. The pixel response speed makes it superior in terms of display type for fast-paced gaming. Panel IPS smears the dynamic picture a littlewhich makes it less suitable for cyber-competitions.

Mobility

AMOLED has become an ideal solution for use in wearable gadgets. In addition to smartphones and tablet computers, this display technology is used in digital cameras, portable music players, portable game consoles, and smart watches.

If the energy efficiency of the device and the longest possible battery life are important, choose AMOLED.
