Modularity

That is what our smart displays are all about. You can easily choose the type of touch panel, mounting frame, or graphics controllers you want, and have the display perfectly fit within your project.

More about

Mechanics / Housing

When you’re thinking about the housing and mechanics your display needs, you need to take into consideration in what kind of environment and in what kind of way it’s going to be used.

For example, if you need a TFT display for your smart home application it’s best to choose something that can be easily mounted to the wall so that the user can quickly and efficiently control the temperature and lighting in their home, over the touch panel.

More about

Graphic and Touch Controllers

Our mission of building intelligent display solutions means that we also offer the best graphics controllers on the market to run them.
