The effect of temperature on optical performance of a dual‐layer liquid crystal display (LCD) is investigated by considering LC material parameter and structural deformation of LC panels simultaneously. First, the optical anisotropy of LC material under the influence of temperature is calculated theoretically. Then, the thermal deformations of the dual‐layer LC panels caused by temperature are simulated. Combined with the two factors, the change in optical performance of a dual‐layer LCD under the influence of temperature can be analyzed. In white state, the color in the central area of a dual‐layer LCD is shifted towards blue, and a yellowish border in the edge area may appear. In gray or black state, there may be a light leakage in the edge area of a dual‐layer LCD under the influence of temperature.

A simple model for investigating the optical performance of LCDs with respect to external forces is presented in this paper. Based on the continuum theory of a liquid crystal (LC) under an electric field, the simple model is established by adding the stress energy density term to Gibb’s free energy density. Besides, the change in cell gap due to external forces is also considered. The parameters in the model are determined by comparing the calculated results with the vertical tensile experiment data. After then, the tilting tensile experiment is performed to verify the simple model. In addition, the LC director distribution and optical performance changes are further discussed. The proposed model can help predict the possible change in the optical performance of LCDs in complex environments and save the product costs.
