摘要：
We propose a new transtlective liquid crystal display with two microlens arrays and a transtlective plate. In this study, with a minimal transmission area on the transflective plate and using two microlens arrays, high light efficiency can be obtained for both the reflective and transmissive modes. In the transmissive mode, square- and cone-shaped microlens arrays are utilized to concentrate the light from a backlight unit. In the reflective mode, reflectance increases due to the enlarged reflective region. From the simulation results, compared with the conventional structure, the light efficiency increased to 97 and 80% in the transmissive and reflective modes, respectively.
