TouchGFX allows you to have high quality graphics on your devices without using external SD-RAM.
Users expect smartphone look and feel, not acknowledging the constraints of limited resources on microcontroller setups. The user expectations require 16-bit color depth normally pushing one to use external SD-RAM for two framebuffers. This requirement for external memory increases the complexity and cost of the hardware development and production cost. We experience a hard push from high volume product manufactures towards saving of external RAM, accepting only a minor UI performance limitation.
