Taking over the duty of displaying content and respond to touch event, Topway launched Smart LCD module couple years ago. Smart LCD is a TFT LCD display module embedded with MCU, display engine and touch controller.
Simple serial commands are all that needed to interact with the screen, no more pixel programming.
Using Topway smart LCD module is very simple. It can be summarized as 5 steps:
Smart LCD module is between traditional TFT LCD module and HMI device. HMI device works as a standalone unit with higher cost. Topway smart TFT LCD provides a cost effective way to quickly implement human - machine interface.
- Graphical UI Editor, enables quick user interface construction, speeds up product's time-to-market
- Preloaded UI design in smart LCD, provides speedy showing and updating
- Embedded display engine, reduces main board workload and over-all cost
- Built-in Lua Script language engine, empowers rich and friendly user interface
- RJ45 port, supports long-distant update and easy expansion
