Abstract: To solve the problems of low reliability and instability of the display in the process of military operations due to the complexity of the external environment and the strong electromagnetic pulse weapons, a design scheme of LCD which uses congenital reinforcement and optical fiber transmission instead of electrical transmission is proposed. Based on the idea of “modular design”, this paper introduces the circuit framework, hardware design and software design in detail. Finally, the performance and environmental adaptability of the whole machine are tested. The results show that the display performance is good in different input signal sources, and the stress screening and electromagnetic compatibility tests are met the requirements of the test outline. The feasibility and practicality of the design scheme are verified.
