Tuesday, May 17. With the feud still simmering between Samsung and LG over active vs. passive 3D glasses, Dr. Min-Sung Yoon, Chief Research Engineer, 3D Technology at, LG Display pulled no punches at his presentation yesterday at the SID Business Conference co-sponsored by Display Search.
The afternoon session by Dr. Yoon focused on his company’s insistence that its version of passive 3D using film patterned retarders (FPRs) truly does represent “A New Paradigm in 3D Display,” with technology advancements that virtually eliminate flicker and cross-talk, and include viewer-friendly features such as light, brightness, and very low-cost 3D glasses.
The technology even supports 3D viewing with your head tilted, or lying down—a claim that two months earlier, prompted a public war of words between rival TV maker Samsung (primarily in the active 3D glasses camp), which publicly announced, “There’s no 3D that works while you are lying down sideways!” A subsequent war of words played out in the Korean media this past March.
The issue gets down to LG’s circular polarization (in FPR approach) versus the linear polarization used in traditional liquid-crystal module (LCM) and shutter glasses. For LG, the string of benefits goes well beyond consumer preferences of low cost, comfort, and simplicity of specifications with the promise of no flicker, low cross talk, enhanced brightness, and frame rate and freedom of motion that includes head tilting while viewing.
We think LG is demonstrating thought leadership in this field, with its consumer preference approach—that may just lead to the next standard (passive shutter glasses) in the 3DTV at home space. Time will tell. -- Steve Sechrist
