A reflector includes a reflective film and a substrate, wherein the reflective film is attached to the substrate. Also, an optical system of an LCD (liquid crystal display) projector includes a first reflector, a second reflector, an LED (light emitting diode) light source, a condenser, a collimating lens, an LCD light valve, a field lens and a projection lens, wherein the LED light source, the condenser, the first reflector, the collimating lens, the LCD light valve, the field lens, the second reflector and the projection lens are set in sequence according to a direction of light. The reflector is significantly improved in the reflection efficiency while maintaining the low cost, or the reflector is significantly reduced in the manufacturing cost while achieving the high reflection efficiency, so that the output brightness and the photoelectric efficiency of the projector including the reflector with low cost, which has a very positive effect.

The invention relates to electronic engineering, more specifically to displays on a car windshield, even more specifically to projection IA qui d crystal displays with biologically adequate backlighting based on semiconductor light-emitting diodes (LEDs) for displaying augmented reality images on a car windshield. The display on the windshield of a car includes LED backlighting arranged in series along the optical axis, Consisting of at least one LED with a peak blue radiation wavelength of 475-490 nm, an optical film system including diffusely scattering and raster prismatic films designed to ensure uniformity illumination radiation, and a composite (zoned) composite photoluminescent film containing photoluminescent substances in a transparent base for converting blue LED radiation into green-blue radiation for the augmented reality display area and red radiation for the warning information display area, monochrome liquid crystal display, a Fresnel lens that magnifies the image formed on the liquid crystal display into the space in front of the windshield of the vehicle. The technical result consists in reducing the harmful effects of display radiation on the body of the driver and passengers of the car, simplifying the design, increasing the reliability and efficiency of the display on the windshield of the car.
