The Evolution of 3D Televisions

Stereoscopic Televisions: Past & Present

Visual depth. That's what today's televisions offer as opposed to their "flat" 2D counterparts. And it didn't seem too long ago either when 3D TVs went mainstream. In reality, it's been almost three years since the first consumer 3D TV was announced. It is debatable, but Hyundai's 46-inch E465S may well be the first 3D screen to land in the consumer space. Since then, 3D televisions have evolved into variants with differing technologies, such as alternate-sequencing (or active-shutter) and polarized forms we see in electronics stores today. Such variety can mean two things - more options for the consumer, but on the contrary, it also hinders standardization efforts with regards to the unification of 3D display technology.

According to sentiments gathered from industry insiders, the current fleet of 3D televisions will find it hard to establish a niche in the consumer market due to their eyewear dependency. To answer that call, Toshiba came up with 12-inch and 20-inch lenticular models back in 2010. By implementing a parallax-barrier approach, both Regza models enabled a user to experience 3D visuals without the need for glasses. Sadly, they failed to take off in terms of sales numbers, due to their tiny screen estate, steep price tags and tight viewing angles. The 20-inch GL1 demanded US$2,900 when it was first launched. Today, 3D TVs are mostly a mix of active-shutter types plus the newly introduced passive flavor by LG. There's more on these in the following pages (you can use the jumps below).
