A backlit display is a type of screen that uses a light source behind the display panel to illuminate the content. This technology enhances visibility, making it easier to see images and text, especially in low-light conditions. Commonly found in devices like smartphones, tablets, and laptops, backlit displays provide vibrant colors and sharp contrasts. The light source in backlit displays can be either LED (light-emitting diode) or LCD (liquid crystal display) technology. LED backlighting is more energy-efficient and offers better brightness control compared to traditional LCDs. This advancement has made backlit displays popular for both personal and professional use.
