FIG. 1.

Structure of the proposed PRLCD.

FIG. 2.

Details of operation of the PRLCD: (a) OFF state, the DDLC cell is homogeneously aligned, and (b) ON state, the sample is written as a TN cell. POL, DDLC, QWP, and TRM are linear polarizer, dye-doped liquid crystal, quarter-wave plate, and transflective mirror.
