The panel of the TV is Neo QLED. The main advantages of Neo QLED panels in TVs are higher brightness and color performance. This is achieved through Mini LED technology, which allows for the placement of hundreds of thousands of smaller LEDs on the back of the screen. This means that Neo QLED TVs can achieve higher brightness than previous generations of LED TVs while maintaining the vibrant and vivid colors provided by QLED TVs. Additionally, Neo QLED technology offers improved contrast and deeper black levels, as most of the smaller LEDs can be individually controlled, giving greater control to the TV for image presentation. Finally, Neo QLED TVs are thinner and lighter compared to older LED TVs, as Mini LED technology requires less space on the back of the screen.

As for HDR, it is equipped with HDR, HDR10+, HLG. High Dynamic Range (HDR) and its various types generally improve the image quality of televisions and other video playback devices. This is achieved by increasing the dynamic range of colors and the brightness of the images.
The advantages of HDR include more vibrant and natural colors, deeper blacks and brighter whites, more details in shadows and highlights of the image, and more accurate color reproduction. Additionally, movie producers can use 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 has a high refresh rate, 100Hz. Increasing the refresh rate results in smoother image motion and reduces blurry or hazy images during 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.
