AMOLED vs IPS LCD | Difference between AMOLED and IPS LCD
This page compares AMOLED vs IPS LCD and mentions difference between AMOLED and IPS LCD. The comparison between AMOLED vs IPS LCD has been done based on various parameters.
Introduction:
AMOLED works on principle of "Electroluminescense" which states material emits light in response to an electric current passed through it
or to a strong electric field.
IPS LCD stands for In Plane Switching which is a TFT-based technology introduced by Hitachi. It is also known as
Super TFT.
AMOLED
In AMOLED, active matrix of OLEDs are deposited on TFT plane. These OLEDs are activated when electric current is applied. The TFT array functions as switches for each pixel. It uses storage capacitor. Typically, OLED display with back panel consisting of TFTs (Thin Film Transistors) is known as AMOLED.

The TFT layer provides greater control over the light emitted by OLEDs. As shown, AMOLED consists of four layers viz. anode layer, organic middle layer, cathode layer and Substrate layer.
The benefits of AMOLED display are as follows.
• It offers true color re-production and greater contrast ratios.
• Consumes less power
• Lighter, Thinner than other display screens
• Offers wide viewing angles.
• Super flexible
• Brighter than LED screens
• Can be made in big screen sizes.
• It can resist instant pressure.
The drawbacks of AMOLED display are as follows.
• Easily damaged by water.
• Higher in cost
• Shorter lifespan than LED/LCD screens
• Due to direct pixel by pixel illumination some OLEDs are used for more duration and hence their performance degrades faster over time. This results into "burn-in effect" in which very brighter screen elements never disappear completely.
IPS LCD
IPS LCD stands for In Plance Switching LCD in which backlight passes through liquid crystals in order to create different colors. In this type of display, black crystals also transmit light and hence they may not be dark. Due to this, contrast ratio is not high as observed in OLED display type. It has been developed to overcome limitations of TN ( twisted nematic field effect ) matrix LCD display type.

The figure depicts working of IPS LCD display. IPS LCD technology has gone through many advances which include S-IPS, AS-IPS, E-IPS, H-IPS and P-IPS ( Professional IPS ).
The benefits of IPS LCD are as follows.
• It offers better color accuracy and image quality.
• It offers longer lifetime than AMOLED.
• It is cheaper in cost.
• It generates very less heat and hence consumes low power.
• It ensures zero color shift.
• It offers wide viewing angle of about 178 degrees.
The drawbacks of IPS LCD are as follows.
• IPS LCD display panel require 15% more power compare to TN panel.
• It has longer response time than TN panel.
• Static contrast ratio is below the average value.
• Motion blur is higher than TN display
Tabular difference between AMOLED and IPS LCD
Let us compare AMOLED vs IPS LCD to derive difference between AMOLED and IPS LCD in following table.
Parameters | AMOLED | IPS LCD |
---|---|---|
Full Form | Active Matrix Organic Light Emitting Diode | In-Plane Switching Liquid Crystal Display |
How it is for eyes ? | Good, AMOLED causes eye strain. | Better |
Contrast ratio and brightness | Blacks are pitch black | Each black pixels emit light and they are not as black as in AMOLED, Hence contrast ratio/brightness is better than AMOLED. |
Power consumption | Less, It uses more power when it uses white display than IPS LCD. | More than AMOLED |
Color accuracy and image | Blacks are better | Whites are better |
Cost | Expensive | Cheaper |
