The TV backlight setting controls the intensity of the light source behind the screen.
Understanding the Backlight Setting
Based on the provided information, the backlight refers specifically to the intensity of the fluorescent lamp behind the screen. The primary function of this backlight is that it "makes the picture more intense".
Adjusting the Backlight for Picture Quality
The way you set the backlight can significantly impact the appearance of the image on your TV. According to the reference, this setting "should be set low to get realistic blacks." This suggests that a lower backlight intensity helps achieve deeper, less washed-out black levels, contributing to a more realistic picture.
By adjusting the backlight, you control the overall brightness originating from behind the display panel itself, influencing how bright the brightest parts of the picture can appear and how dark the darkest parts can be rendered, particularly when aiming for accurate black tones.
