Application Case of Kyocera TCG121XGLPBPNN-AN40 in Rail Transit Cockpit Display
News 2026-05-13
The driver’s cab display in rail transit plays a crucial role in displaying operational status, providing fault alarms, and showcasing vehicle control information and diagnostic data. As a vital interface between the driver and the train system, the display must maintain stable operation in environments with high vibration, wide temperature ranges, and long-term continuous operation.
A rail transit equipment manufacturer, developing a new generation of driver display units (DDUs), sought a mature and reliable industrial LCD screen to meet the safety and stability requirements of domestic and international rail projects. After fully understanding the client’s needs, we recommended Kyocera industrial displays. Following evaluation and sample testing, the client ultimately adopted the Kyocera TCG121XGLPBPNN-AN40 as the core display solution.
Project Background
The client primarily supplies cockpit electronic equipment for subway, intercity trains, and light rail vehicles. The products must meet the following requirements:
1024 × 768 XGA resolution
High brightness, adaptable to various lighting environments
Wide operating temperature range
Long-term stable supply
Good vibration resistance
Support for 24-hour continuous operation
