Recently, I have seen a lot of people in social communities expressing keen prejudice towards AMOLED displays, justifying even the back draws in many cases. Let’s dive in for a more detailed review of AMOLED vs LCD, how this actually works, and which aspect of it contrasts more for you.




LCD Panels

First, let’s discuss LCD panels. LCD stands for liquid crystal display. These displays have super thin adhesive layers which help cling to filtering liquid encompassing a big mass of electrodes.

A bright source of light contrasts these crystals individually thus projecting differentially contrasted spectrums in space, which is yet again managed by the second last film layer which narrows out a specific range depending on the voltage supply and hence displays that particular thing on the panel (as per the signal).

LCD panels are of various types depending on how the electrode mnemonics, exempli gratia, IPS (in-plane switching), TN (twisted nematic), and VA (vertical alignment). The focus is on IPS, and how is it different/superior (if so) from the rest of the LCD panels.

IPS Panels

In IPS panels, the crystals are oriented horizontally in the same concurrent plane as the adhering layer, unlike TN panels, which show abrasions over time, as well as have micro-twisting as the present crystals have 3-dimensional shifts. IPS panels have the crystals with a varying specific gravity throughout the length of individual crystals as well as varying refractive index. This helps the applied voltage rotate the crystals hence letting out certain amount of light in a particular spectrum.

TN Panels

TN panels, on the other hand, showing 3-dimensional orientation show compromise on color accuracy to provide extremely fast-moving crystals with the help of evaporative condensers that help with as fast as signal switches of frequency as little as 10 microseconds.

VA Panels

VA panels allow only vertical alignment (as the name itself suggests) of the crystals. This causes the crystals to stand perpendicular to the adhering layer – thus lowering the time period for individual shifts. This significantly reduces the response time of any panel using LCD VA logics.

Evaporative condensers cannot be used as there will be considerable signal losses, and the excessive torque produced in the crystals might cause a huge conglomerate of dead pixels in a very short amount of time of usage. This gives the best color accuracy, but by sacrificing color accuracy. In some cases, even the viewing angles are compromised a little, still better than TN panels.

This puts IPS panels as the best choice unless gaming is a necessity (TN panels), or you’re a pro display freak (VA panels). IPS panels maintain the perfect balance between viewing angles, refresh rate, and color accuracy, hence widely popularized in mid to high range consumer line products.


Another technique is DC dimming. In this case, the power supplied to the whole circuit is controlled by varying either of the direct inputs irrespective of their frequency. Although this technique is widely used in LCD panels due to the only backlight controller there is, it’s recently being seen added to AMOLED displays too.

The defect however is, at lower inputs, the colors are either not contrasted at all, or just seem to lose gamut highlights. This is one of the major reasons why most of OLED displays are advertised to have as high as 1000 nits or nearly 3150 lux of brightness. Also, a majority of OLED displays are advertised with larger color space controllers.

This is not a luxury the manufacturers are providing you for extra cost. It’s actually the mandation, otherwise, the display would look horrible than a TN panel. And because of this, the displays are actually charged more. A way to convert a curse to a boon. Click!


Hence, IPS or AMOLED. Here a few key points that might matter for the final call/judgment (depending on whether you’re purchasing stuff or in an argument with someone else).

IPS Panel


  • Long-lasting
  • Much subtle and contrasted whites
  • Better color reproduction
  • Comparatively fast response time


  • Limited Contrast Ratio
  • Loss of color vibrancy
  • Higher power consumption even on the dim backlight


Advantages :

  • Consumes less power
  • Vibrant Colors
  • Blacks are effectively off pixels, thus increasing immersiveness
  • Provides amazing color accuracy and contrast (only when color spaces are higher)

Disadvantages :

  • Loses a certain fraction of luminosity over time
  • Since individual pixels’ capacitors (usually the cheap ones) might use paper filtering for charge bypasses, it often leads to impression persistence, also known as pixel burns, especially when used with higher input supply.
  • Since the majority are still using PWM, so harmful to the human eyes, might cause eye strain, headache, even color blindness (not official, but reported)

Well, hope this solves the AMOLED vs LCD feud.
