Embodiment 1
[0086] Example 1: Reference Figure 22 , 5 , 12, 14, 15, 16, 20, 1, 9, 10, 21, 27, 32-inch LCD TV light guide plate and its LCD TV
[0087] Picture 10 It is a schematic diagram of the side structure of a 32-inch LCD TV honeycomb-shaped high-efficiency and energy-saving microstructure light guide plate. The light guide plate includes a colorless and transparent methyl methacrylate flat-plate substrate 1. A light-incident side end surface for receiving light into the interior 2 , The light-emitting plane 4 that is opposite to the light-incident side end face and intersects with the reflective side end face 5 coated with a reflective film, and the light that intersects the light exiting plane 4 from the inside, and the bottom plane 3 with the scattering microstructure pattern opposite to the light-emitting plane 4 Structure, wherein the microstructure scattering three-dimensional pattern layer on the bottom plane 3 is formed by coating the bottom plane of the substrate with a layer ...
Embodiment 2
[0096] Example 2, reference Figure 23 , 11 , 12, 17, 18, 19, 20, 3, 21, 27, 42-inch light guide plate and its LCD TV
[0097] Picture 11 It is a schematic diagram of the side structure of the honeycomb-shaped high-efficiency energy-saving microstructure light guide plate of a 42-inch LCD TV, including a colorless and transparent methyl methacrylate flat plate substrate 1, at least one light-incident side end surface for receiving light into the interior 2, The light exit plane 4 opposite to the light entrance side end surface and the other intersecting reflective side end surface 5 coated with a reflective film, and the light that intersects the light exiting from the inside, and a bottom plane 3 with a scattering microstructure pattern opposite to the light exit plane 4 , Wherein the microstructure scattering pattern on the bottom plane 3 is formed by coating the bottom plane of the substrate with a layer such as Figure 5 The distribution pattern shown is used to adjust the ov...
Embodiment 3
[0105] Example 3: Reference Figure 24 , 2 , 13, 14, 15, 16, 20, 21, 27, 14 inch light guide plate and its laptop
[0106] Figure 24 It is a 14-inch colorless and transparent PC wedge substrate 1 (such as figure 2 ) Is a schematic diagram of the side structure of a honeycomb-shaped high-efficiency energy-saving microstructure light guide plate for a laptop computer, the light guide plate includes a colorless and transparent wedge-shaped PC substrate 1, at least one light-incident side end surface 2 for receiving light into the interior, and a light-incident side end surface The remaining opposite and intersecting reflective side end faces 5 are pasted with reflective films, and the light exiting plane 4 from which the intersecting light exits from the inside and the bottom plane 3 opposite to the light exiting plane 4 with a scattering microstructure pattern are formed, wherein the bottom plane 3 The micro-structure scattering three-dimensional pattern layer on the substrate is ...
