AMO-LED display mobile explained

We’ll start alphabetically with AMO-LED display mobile, although to be a little broader we should probably start with a little background about OLED technology in general.

It’s hidden in the name, but the key component in these display types is a Light Emitting Diode (LED). Electronics hobbyists will no doubt have played around with these little lights before. In a display panel, these are shrunk down dramatically and arranged in red, green, and blue clusters to create an individual pixel that can reproduce white light and various colors, including red, green, and blue.

The arrangement of these sub-pixels alters the performance of the displays slightly. Pentile vs striped pixel layouts, for example, results in superior image sharpness, but lower pixel life spans due to the smaller pixel sizes.

The O part in O-LED display mobile stands for organic. Simply put, there are a series of thin organic material films placed between two conductors in each LED display mobile, which is then used to produce light when a current is applied.

Finally, the AM part in AMO-LED display mobile stands in for Active Matrix, rather than a passive matrix technology. This tells us how each little O-LED display mobile is controlled. In a passive matrix, a complex grid system is used to control individual pixels, where integrated circuits control a charge sent down each column or row. But this is rather slow and can be imprecise. Active Matrix systems attach a thin film transistor (TFT) and capacitor to each LED. This way, when a row and column are activated to access a pixel, the capacitor at the correct pixel can retain its charge in between refresh cycles, allowing for faster and more precise control.

One other term you will encounter is Super AMO-LED display mobile, which is Samsung’s marketing term for a display that incorporates the capacitive touchscreen right into the display, instead of it being a separate layer on top of the display. This makes the display thinner.

The major benefits from O-LED display mobile come from the high level of control that can be exerted over each pixel. Pixels can be switched completely off, allowing for deep blacks and a high contrast ratio. Great if you want a display capable of playing back HDR content. Being able to dim and turn off individual pixels also saves on power ever so slightly. The lack of other layers on top of the LEDs means that the maximum amount of light reaches the display surface, resulting in brighter images with better viewing angles.
