The features of 3D TVs are designed to provide an immersive viewing experience, enhancing the sense of depth and realism. Key features include:

1. Stereoscopic Display: 3D TVs use two separate images, one for each eye, to create a stereoscopic effect. This is achieved through active shutter glasses or polarized glasses, which alternately block the left and right eyes to view the separate images.

2. High Resolution: To maintain image quality, 3D TVs typically have high-resolution displays, such as 1080p or 4K, to ensure that the 3D effect is clear and sharp.

3. Motion Control: Many 3D TVs incorporate motion control technology, allowing users to navigate through menus and select content using hand gestures or voice commands, reducing the need for traditional remote controls.

4. 3D Content Compatibility: To fully utilize the 3D feature, 3D TVs must be compatible with 3D content. This includes support for 3D broadcasts, 3D movies, and 3D video games.

5. Built-in Speakers: Many 3D TVs come with built-in speakers, providing a surround sound experience that complements the 3D visuals.

According to a report by Statista, the global 3D TV market size was valued at approximately $11.6 billion in 2020 and is expected to grow at a CAGR of 5.2% from 2021 to 2028. This growth is driven by the increasing demand for immersive entertainment experiences and the advancement of 3D technology. The report also highlights that the rise in 4K and 8K resolution 3D TVs is contributing to the market's growth, as these higher resolutions provide a more realistic 3D experience. Additionally, the availability of a wide range of 3D content, including movies, sports, and video games, is further fueling the popularity of 3D TVs.
