In the realm of home entertainment, 3D movies on TVs have become increasingly popular. Modern TVs utilize a variety of technologies to project stereoscopic images, creating a sense of depth and immersion for viewers. The primary methods include active shutter glasses, passive 3D technology, and autostereoscopic displays. Active shutter glasses synchronize with the TV's refresh rate, alternately blocking each eye's view to create a 3D effect. Passive 3D technology uses polarized glasses and alternating polarized layers on the screen to achieve the same effect. Autostereoscopic displays, on the other hand, use lenticular lenses to project different images to each eye simultaneously, eliminating the need for glasses. According to a report by Grand View Research, the global 3D TV market size was valued at USD 6.1 billion in 2020 and is expected to grow at a CAGR of 11.5% from 2021 to 2028.

The choice of technology depends on various factors, including the viewer's preference, the type of content, and the TV's capabilities. Active shutter glasses provide the most immersive experience but can be uncomfortable for some viewers due to the alternating blackouts. Passive 3D technology is more affordable and less likely to cause eye strain, but it may not offer the same level of depth as active shutter glasses. Autostereoscopic displays are still in the early stages of development and are not widely available in the consumer market. However, they have the potential to revolutionize the way we watch 3D content by eliminating the need for glasses altogether.

The rise in popularity of 3D TVs can be attributed to several factors. Firstly, advancements in display technology have made it possible to produce high-quality 3D images with minimal crosstalk and ghosting. Secondly, the availability of 3D content has increased significantly, with many studios releasing movies in both 2D and 3D formats. Lastly, the cost of 3D TVs has decreased over time, making them more accessible to the average consumer. According to a study by IHS Markit, the number of 3D TVs sold globally reached 100 million units in 2019, and this number is expected to grow as more consumers adopt 3D technology for their home entertainment systems.
