This paper analyzes the performance of a pixel-level three-dimensional local dimming backlight unit. The illuminance distribution function based on the double-layered structure is derived and simulated by using MATLAB. A 5-inch LCD screen is tested, and the dark brightness and contrast of the single-layered structure and the double-layered structure are compared.
