This invention provides a direct-lit
fiber optic backlight module, including a light-emitting component and an
optical fiber. The light-emitting component's light-emitting end is connected to the light-input end of the
optical fiber. The
optical fiber includes a core, an outer sheath, and multiple exposed sections with the sheath removed. Each exposed section of the core has multiple
light emission points. A semi-transparent layer covers the
light emission points on the exposed sections of the core, and a light diffusing agent is placed within the semi-transparent layer. The outer surface of the semi-transparent layer has a textured surface. This invention not only significantly reduces the backlight thickness but also provides excellent
light emission, improving the overall performance of the backlight.
