Nextion HMI TFT LCD Display:A Basic Introduction

Nextion Hardware

Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube. Available from 2.4″ to 7″ models, Nextion provides an analog touch screen operator interface with programmable function buttons, gauges, progress bars…etc., Nextion is an interface solution designed to complement your application needs.

Nextion Display has so many goods, you may not have a thorough understanding for it. In following blog series, I will give a comprehensive introduction for Nextion. If you are a green hand, these blogs are just the things to help you get started.

This blog will talk about Nextion hardware, product competitive advantages and model guide particularly.

Firstly, let’s learn basic structure of Nextion. Although there are some differences among the models, below image is for your reference.

There are 6 sizes of Nextion available for your selection: 2.4″, 2.8″, 3.2″, 4.3″, 5.0″ and 7.0″. Users can see the overall detailed parameters from the below table:

Nextion Competitive Advantages

Nextion TFT display uses only one serial port to do communication which helps users get rid of the wiring trouble. We notice that most engineers spend a lot of time in application development but get unsatisfactory results. In this case, Nextion editor has provided mass components, such as button, text, progress bar, slider, instrument panel etc. to enrich your interface design. And the drag-and-drop function ensures that users will spend less time in programming, which will reduce your 99% development workloads. With the help of this WYSIWYG editor, GUI designing is a piece of cake.

Nextion display is just the choice to solve your programming problems with the minimum of time and effort. Nextion is a better solution than ever, as users can see its competitive edges as below, not to mention its good price:

1. Provide some small size TFTs that absent in the market.
2. Character string commands, reduce debugging difficulty.
3. Objective-oriented controlling method. Nextion supports the commands not only to draw points or lines, but also to control most attributes of the components and materials.
4. Users can control the objects in a demo through serial port commands by external MCU even the demo has already been downloaded and demonstrated on Nextion screen.
5. Fully functional software.
*A WYSIWYG editor. Users can drag-and-drop any component in the editor to simplify their interface design.
*Rich set of components. Many general elements in HMI design have been packed into controls. Users can evoke them directly.
*Custom component. Users can design their own components to meet their demand.
