To implement Fast Update (or Partial Update), you will need to send images continuously but most of the time the pixels to be changed are usually in small areas or from some fixed objects. If there is no graphic generating tool or image production engine to handle these small changes, the output effect will be greatly reduced and will increase the system load.

To improve system-level performance and enhance the visual experience for your IoT or smart devices, the best solution is to use an image library for graphics that are likely to be subject to fast updates. For example, if the application is an interactive user interface featuring some strings, value changes and button controls, the image library could contain fast update algorithm for each possible state of the elements. This also applies to common features, such as a radio buttons, progress bars, sliders or checkbox.
