Description

technical field

[0001] The invention relates to the technical field of rail transit train information display, in particular to an adaptive intelligent adjustment outside LED display system for improving the comfort of rail train passengers. Background technique

[0002] In conventional rail transit train applications, LED dot-matrix display screens outside the train are installed on the front of the train and on both sides of the train body, providing passengers on the platform with information such as train number, train number, starting station, terminal station, current station, guidance information, smoking ban, etc. Logo and other text, icon information.

[0003] At present, the external LED displays commonly used in rail transit trains use constant current to drive high-brightness or ultra-high-brightness single-color or two-color LED dot matrix methods. The display brightness cannot be adjusted, and the brightness setting of the external LED display only considers th...
