Custom 4.7" TN TFT Display for Genset Controller | MIPI Interface Solution

12.03.2025

In generator set (Genset) control systems, the display screen needs to remain stable and reliable under high vibration, temperature rise, and long-term operation. To meet the client's needs in the controller project, we customized a 4.7-inch, 720x1280 resolution, MIPI interface TN TFT display screen, achieving clear data display, fast response speed, and flexible structural adaptation.

 

This article will guide you through the background of this project, client requirements, customization highlights, and final results.

 

01 Project Background

 

The client is developing an upgraded version of the Genset controller and needs a display solution that can withstand the test of industrial environments while offering high cost-effectiveness.

 

Traditional displays often encounter the following problems in such scenarios:

 

Insufficient brightness, difficult to adapt to complex lighting conditions

 

Slow dynamic refresh rate, unsmooth pointer or number changes

 

Interface incompatibility, increasing hardware costs

 

Unstable screen lifespan, prone to aging under long-term operation

 

The client wanted to find a... High-resolution, fast-response, stable, and perfectly compatible TN TFT display with the main controller.

 

02 Customer Core Requirements

 

1) Higher resolution for enhanced interface detail

 

A 720x1280 resolution provides a more refined instrument UI, especially suitable for displaying information such as speed, voltage, and temperature.

 

2) Seamless MIPI interface integration with the main controller

 

The customer's main controller uses MIPI DSI, therefore the display needs to support high-speed transmission, low power consumption, and smoother animation.

 

3) TN screen, a cost-effective solution

 

Compared to IPS, TN offers a cost advantage while maintaining stable performance in industrial controllers, meeting the customer's overall budget.

 

4) Industrial environment stability

 

For Genset controllers operating for extended periods, the display needs to possess:

 

Stable driver IC

 

Enhanced backlight lifespan

 

Vibration-resistant FPC structure
