Why AMOLED for your wearable device

AMOLED displays have become increasingly popular on wearable devices due to their many benefits over traditional display technologies like TFT LCDs.

One of the most notable benefits of AMOLED displays is their deep black levels. This is because each pixel in an AMOLED display is lit independently, meaning that when a pixel is turned off it appears completely black. In comparison, traditional displays use a backlight that illuminates all pixels at once, leading to gray levels even when a pixel is turned off. This results in better contrast and more vibrant colors, making for a much better viewing experience.

Another benefit of AMOLED displays is their lower power consumption. Since each pixel is lit independently, the display only uses power when displaying content. This is in contrast to traditional displays that consume power even when displaying black. This means that AMOLED displays can greatly extend the battery life of wearable devices.

In addition, going into a little more technical speak, AMOLED displays have their driver ICs on the flex cable rather than on the glass which reduces the overall "hard" dimensions. This is especially important for devices such as smartwatches and fitness trackers, which need to look aesthetically pleasing with more screen real estate ratio to the entire device on the wrist when worn.

Finally, AMOLED displays also have fast response times, making them ideal for displaying fast-moving content such as video and animations. This means that users can enjoy a smooth and fluid viewing experience, even on small wearable devices.

Overall, AMOLED displays offer many benefits over traditional display technologies and are a great choice for wearable devices. Whether you're looking for better contrast, longer battery life, or a more screen form factor, AMOLED displays are the way to go.

With the touch layer being in cell or on cell, the overall thickness is also reduced over adding an external touch panel sensor layer.
