AMOLED – What is it?

AMOLED stands for (active-matrix organic light-emitting diode). It is a display technology used in mobile phones, watches, laptops and televisions. It uses a thin film display technology in which organic compounds from electroluminescent material is brought into the action, along with it active matrix technology is used to address the pixels.

This concept was used in mobile phones in the year 2008. And in the same year it found its place in digital cameras and other media devices and further it continued to made progress in an efficient way, by making efficient power control, low cost and large-size applications.

The main fabricators of this technology are AU OPTRONICS and SAMSUNG. SAMSUNG has marketed this by the name “SUPER AMOLED”.


The major disadvantage is related to the life span of the OLED films used, that is the red and green OLED films have longer life spans when compared to the blue OLED films. And the major effect of this is the variation in color as the color shifts as a particular pixel fades faster than the other pixels.

Another disadvantage of AMOLED displays is the SCREEN BURN IN issue, which leaves an imprint of the overused colors which in turn is caused due to over used images.



AMOLED displays provide higher refresh times which mainly reduces the response time to less than a millisecond, and this technology consumes less power. This advantage makes the active matrix OLED’s very well suited for electronics, where power consumption is always an issue related to the battery life. AMOLED display has higher contrast ratios than that of the LCD; the main reason for this is the black pixel turn off completely due to the above matrix technology used.


Below is a mapping table of marketing terms versus resolutions and sub-pixel types. Note how the pixel density relates to choices of sub-pixel type.
