Embodiment Construction
[0030] The present invention will be described in detail in conjunction with accompanying drawing now. This figure is a simplified schematic diagram only illustrating the basic structure of the present invention in a schematic manner, so it only shows the components relevant to the present invention.
[0031] Such as Figure 1-2 As shown, an optically controllable quantum dot backlight of the present invention includes sequentially stacked blue light source components 1 and an optical plate 2, a quantum dot layer 21 is provided on the light incident end surface of the optical plate 2, and the optical A microstructure 22 is provided on the light emitting end surface of the plate 2, and the microstructure 22 is a convex lens structure. The microstructure 22 performs primary light mixing, and has the functions of light guiding and light concentrating. The blue light source assembly 1 also has multiple implementations. In this embodiment, two types of structures are provided: di...
