Lumex's latest family of ezDisplay includes various displays such as RGB LED Dot Matrix Display, OLED module and Monochrome LCD Module. With the built-in UART interface or attached Lumex UART module, the experience of managing a LED Display, OLED or LCM is extremly smooth than it ever was. Drawing a triangle, rectangle or a circle is not a problem. Writing something is so simple and straight forward.

Lumex has integrated the control mcu, driver IC and communication interface together to provide the best user experiences. Benefit by the UART interface, Lumex ezDisplay products is able to be managed by only four wires and fit for single board computers such as raspberry pi and arduino. Besides direct attached by using the UART interface, it can be extended by attaching USB to UART, Bluetooth to UART and RF to UART moudule.

There is no limitation of programming languanges while using Lumex ezDisplay. Lumex ezDisplay works with C, python or micro.bit. Actually, ezDisplay can be done by using serial console software.

Furthermore, all displays are running the same commands; users can easily change from one to the other based on different application needs.

Lumex ezDisplay related product is desgined to simplify the barriers of managing multiple LEDs, OLED and LCM. There are two major parts in all Lumex ezDisplay related prodcts, the controller and the media. Lumex ezDisplay Controller is used to interpreter user commands to electronic signals, this is also the core of Lumex ezDisplay. There are several products currently available in this categories.
