Hud car display
As a rule, the HUD system contains three main components: the accumulator, which is the surface on which the image is projected (usually the windshield with the coating); a block design, which is usually an LED or LCD display; and the control module that produces the image and determines how it should be projected. The first displays on the windshield use ELT displays to project the image on the windshield. They were replaced by systems that use LEDs or LCD displays. External light sensors detect the amount of light that falls on the windshield from the outside of the car and regulates the intensity of the projection, respectively.
