When an electric current is passed through these dots, they emit light of a specific color, resulting in a more accurate and vibrant color reproduction.
The quantum dots are arranged in a layer, which is then placed in front of a backlight. The backlight produces a white light, which passes through the quantum dot layer, creating the desired colors. This technology offers several advantages, including:
Better color accuracy: QLED TVs can produce a wider range of colors, resulting in a more lifelike viewing experience.
Improved brightness: QLED TVs can reach higher peak brightness levels, making them ideal for bright room viewing.
Wider viewing angles: QLED TVs maintain their color accuracy and contrast even when viewed from the side.
Diving into LED Technology
LED technology, also known as LCD (Liquid Crystal Display) technology, is a more traditional display technology. It uses a layer of liquid crystals to block or allow light to pass through, creating images on the screen. The liquid crystals are arranged in a matrix, with each pixel consisting of three sub-pixels: one for red, green, and blue. By combining these sub-pixels, the TV can produce a wide range of colors.
In an LED TV, the backlight is usually an array of white LEDs positioned around the edges of the screen or behind the panel. The light from these LEDs passes through the liquid crystal layer, creating the images on the screen.
