  • Patent number: 11282985
    Abstract: The present invention discloses a flip-chip LED chip used in a backlight and a producing method thereof. The flip-chip LED chip used in the backlight comprises a substrate, an epitaxial layer, a transparent conductive layer, an insulating layer, a first reflecting layer, a second reflecting layer, a first electrode, and a second electrode. In the present invention, the first reflecting layer and the second reflecting layer are formed on both sides of the substrate. By adjusting the reflectance of the first reflecting layer and the second reflecting layer, the light emitted by the epitaxial layer is reflected by the first reflecting layer and the second reflecting layer, resulting in 20-40% of the light being emitted from the back of the chip, and 60-80% of the light being emitted from the side of the chip. This increases the light uniformity of the LED backlight.
