The TV panel is OLED. The OLED panels in televisions have many advantages over other types of panels, such as LCD and LED. Some of the advantages of the OLED panel are as follows:

1. Absolute black: The pixels of the OLED panel can turn off completely, allowing for the most absolute black in scenes. This creates an impressive contrast in images and adds depth and realism to the appearance of colors.

2. Wider color gamut: The OLED panel allows televisions to display a wider color gamut compared to other types of panels. This means that OLED televisions can display more natural, vibrant, and accurate colors.

3. Excellent viewing angle: OLED panels exhibit extremely wide viewing angles, unlike other types of panels that may deliver lower image quality when the viewer is not directly in front of the screen.

4. Response to fast-moving scenes: OLED panels have the ability to respond to fast-moving scenes with greater accuracy and without color "fading" that can occur in other types of panels.

5. Slim design: OLED panels are very thin, allowing for the creation of slimmer and more elegant designs for televisions.

Regarding HDR, it is equipped with Dolby Vision, HDR10, HDR10+, HLG. High Dynamic Range (HDR) and its various types generally improve the picture quality of televisions and other video playback devices. This is achieved by increasing the dynamic range of colors and brightness of images.
The advantages of HDR are more vivid and natural colors, deeper blacks and brighter whites, more details in the shadows and highlights of the image, and more accurate color reproduction. Additionally, filmmakers can utilize HDR to produce movies with more natural and realistic images.
Finally, devices with HDR support can play content that is encoded with HDR, offering a more impressive viewing experience for the user.

It features a high refresh rate, 120Hz. Increasing the refresh rate results in improved image smoothness and reduced blur or ghosting during the dynamic presentation of fast movements or high-motion scenes. This makes the experience of watching movies, series, sports events, and games more realistic and impressive.

Smart TVs represent an evolution in television technology, as they incorporate Internet functions, allowing web browsing and the use of online applications (e.g., Netflix, YouTube, Spotify, etc.). They are, in other words, an example of technological convergence between computers and televisions.
