A "full-array" display refers to a type of LED television that uses a grid of LEDs placed directly behind the screen. This setup allows for more precise control of brightness and contrast in different areas of the image. By adjusting the light in specific zones, full-array displays can produce deeper blacks and more vibrant colors compared to edge-lit displays, where LEDs are only positioned around the edges. Full-array technology often includes features like local dimming, which enhances the viewing experience by dimming or brightening specific sections of the screen. This results in improved picture quality, making it a popular choice for home theaters and gaming setups.
