Embodiment Construction
[0038] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0039] refer to figure 1 and figure 2 As shown, a substrate for improving the brightness of a backlight disclosed by the present invention is provided with a plurality of raised three-dimensional patterns 2 on the surface of the substrate 1, and on the surface of the substrate 1 between the plurality of raised three-dimensional patterns 2 The recessed three-dimensional patterns 3, so that a plurality of recessed three-dimensional patterns 3 are arranged on the surface of the substrate 1. The substrate 1 is preferably a sapphire substrate, and may be other substrates.
[0040] A plurality of recessed three-dimensional patterns 3 are arranged on the surface of the substrate 1, which increases the reflective area of the substrate 1 and effectively improves the luminous efficiency of the light-emitting diode; the use of the recessed three-di...
