The objective of this study is to assess the potential applications of in-plane switching (IPS) liquid crystal displays (LCDs) in augmented reality (AR) systems, with a specific emphasis on their advantages in rapid switching performance. Owing to their exceptional wide viewing angle and superior color fidelity, IPS-LCDs have emerged as a prominent contender in the field of modern display technologies, exhibiting notable technical advantages in display design. The experiment utilized the nematic liquid crystal material ZLI-2293, and its switching performance between transparent and opaque states was further validated through voltage-varying transmission techniques. The results demonstrated that the IPS-LCD mode offer exceptional contrast and precise display control, which contribute to enhanced image realism. Furthermore, the wide viewing angle of this technology makes it particularly well-suited for AR applications, as it improves the user’s immersive experience by maintaining image consistency, especially during movement and when viewed from different angles. The findings of this study suggest that the IPS-LCD will serve as a critical driver in advancing future augmented reality devices, accelerating the development of next-generation immersive technologies. This progress is expected to lay a foundation for the creation of more realistic and interactive virtual reality environments.
