In the field of professional communication equipment, the display screen not only serves the function of information presentation but also directly affects the usability and reliability of the equipment in complex environments. To meet the project requirements of our German client, we custom-developed a 7-inch high-brightness TFT LCD display module with integrated capacitive touch (CTP), specifically designed for industrial-grade communication equipment.

Project Background

This German client specializes in the research and development and manufacturing of communication equipment. Their products are typically used in outdoor or semi-outdoor environments, placing high demands on the display system:

Moderate screen size, convenient for integration into the equipment panel

High-brightness display, ensuring clear readability in bright light environments

Sensitive touch operation, supporting stable human-machine interaction

Wide temperature range and environmental resistance, meeting industrial-grade usage scenarios

Compliant with European environmental and regulatory standards
