Abstract: GL Studio is a professional simulation platform, it is very convenient to make use of GL Studio in the development of virtual models of mechanical instrument. But with the growth of electronic and information technology, more sophisticated and complex electronic display devices have been widely used in the field of machinery, electronics, aviation and military training, which left a difficult problem to the development of virtual instrument. LCD numeric display is a kind of familiar electronic display devices. Aiming at the characteristics of the LCD numeric display, a method to the development of the LCD numeric display virtual models based on GL Studio is put forward, and it is resulted to be available through an experiment. 

Key words: GL Studio, modeling, simulation, numeric display
