Description

technical field [0001] The invention relates to a human-computer interaction unit display device, in particular to a human-computer interaction unit display device applied to railway locomotive vehicle digitization and graphic display processing, and the invention can also be used in similar field human-computer interaction unit electrical products. Background technique [0002] At present, with the development of railway locomotive equipment, the human-computer interaction unit equipment has developed from the initial digital tube display to the stage where LCD liquid crystal screen displays are widely used. The liquid crystal screen display has richer information, and provides a good human-computer interaction interface in the form of graphics, curves and text, and is very popular among users. LCD screen display instead of digital tube display has become inevitable. [0003] There are usually two technical solutions for the circuit design of LCD screen displays in existin...
