Display devices and related methods involving patterned phase retarding are provided. A representative display device includes: a backlight unit, having a light source and a color conversion layer having an alignment direction, the light comprising a first light exhibiting a first upstream polarization ratio, a second light exhibiting a second upstream polarization ratio, and a third light exhibiting a third upstream polarization ratio; and a patterned phase retarder positioned to receive the light, having a plurality of half-wave regions to alter polarization of light passing therethrough, and a plurality of free regions to pass light without altering the polarization; wherein polarization ratio (PR) is defined by PR=(I&#x2212;I)/(I+I); and wherein the first upstream polarization ratio exhibits a first sign, and both the second upstream polarization ratio and the third upstream polarization ratio exhibit a second sign opposite the first sign.

Liquid crystal display (LCD) systems and related methods with pixel elements driven at different frequencies are provided. A representative LCD system includes: a plurality of pixel elements arranged in an array, each of the plurality of pixel elements having a first sub-region and a second sub-region; a low-frequency driving circuit operative to drive each of the first sub-regions; and a high-frequency driving circuit operative to drive each of the second sub-regions at a driving frequency different than a driving frequency of the low-frequency driving circuits; wherein the first sub-regions exhibit a different size than the second sub-regions.
