The digital product design platform of liquid crystal display module was established. The construction method of design platform was made clear， and the standardization and universality of product design were improved. The example showed that this design platform construction method could improve the borrowing rate of mature design scheme and data model， shorten the design cycle， improve the reliability of products， and was testified to be feasible and practical， which had certain reference significance for the design and development of liquid crystal display module with different shapes for mass customization.
