“…The Berreman method is widely used due to its simplicity while the FDTD method compensates its difficult implementation by producing more accurate results in textured LCs. In this section, the relevant features of the two optical methods are discussed; details are found in the literature [32][33][34][35][44][45][46][47][48][49][50][51][52][53][54]. The discrepancies, advantages and disadvantages of the two methods has been discussed in our previous work [36][37][38].…”

“…For example, the cholesteric liquid crystal (CHLC) can reflect one component of circular polarization, and the multi-layer polymer film with birefringence can reflect the light in different amounts with respect to the two linear polarizations [2,3]. The wire-grid polarizer also belongs to the reflective polarizer and finds its use frequently in micro-wave applications.…”

Numerical calculations were carried out to find the mechanisms of a nanofiber based reflective polarization sheet (RPS) using the finite-difference time-domain (FDTD) method. The simulation showed that the birefringence of nanofiber layers can make a reflective polarizer with small energy loss. In addition, the simulation demonstrated that the diameter of nanofibers and the spacing between them affected the extinction coefficient of RPS depending on its polarization. According to the calculations with various diameters of the nanofiber, there exists an optimum diameter of the nanofibers for maximum extinction coefficient.

“…There are three types of reflective polarizers: the multilayer type [1], the wire grid type [2], and the cholestericliquid-crystal (CLC) type [3]. Among these, the multilayertype reflective polarizer is the most widely used in the LCD technology.…”

The correlation between the optical performance of the reflective polarizer, which is a key optical component for the brightness enhancement of the liquid crystal display (LCD), and the configuration of optical sheets was investigated in a direct-lit CCFL (cold-cathode fluorescent lamp) backlight. The optical gain of the reflective polarizer, the polarization state of the light emitted from each film, and the loss factor for the polarization conversion process occurring in the lower part of the backlight were determined using a phenomenological approach for the polarization recycling process. The present study suggests that the correlation between the optical performance of the brightness enhancement films and the backlight configuration should be carefully considered in the optimization of the backlight structure.
