2results about How to "Improve optical utilization" patented technology

The utility model discloses a car lamp lens module, including radiator, light source board, lens support and be located in the lens support's lens structure, the light source board is located on the radiator, and the lens structure sets up correspondingly the light source on the light source board, the lens structure is three piece type lens structure, and three piece type lens structure includes three lenses that set up in order along the light path, and one of them is double cemented lens. The car lamp lens module structure design is reasonable, and it adopts three piece type lens module structure, and one glass lens adopts double cemented lens, so that can realize four piece type lens module's optical effect, can also improve optical utilization rate, and simultaneously because has reduced the lens quantity more easily to assemble, has reduced the assembly tolerance, has improved the production consistency.

The invention discloses a backlight display system, an application method and a related product, and is characterized in that the backlight display system comprises a backlight layer, a metasurface micro-nano structure layer and a liquid crystal display layer; the backlight layer is used for providing a red light source, a green light source and a blue light source; the super-surface micro-nano structure layer is arranged between the backlight layer and the liquid crystal display layer and used for spatially separating a red light source, a green light source and a blue light source emitted by the backlight layer according to wavelengths and guiding the red light source, the green light source and the blue light source to a corresponding red sub-pixel area, a corresponding green sub-pixel area and a corresponding blue sub-pixel area in the liquid crystal display layer; and the liquid crystal display layer is used for regulating and controlling the light transmittance of the red sub-pixel region, the green sub-pixel region and the blue sub-pixel region so as to realize image display. Therefore, the optical utilization rate can be remarkably improved, the liquid crystal display brightness is further improved, the system power consumption is reduced, and meanwhile the high-precision color display capacity is kept.
