Abstract

The invention relates to an optical waveguide film, a head-up display with the optical waveguide film, a colored head-up display and a head-up display system. The optical waveguide film comprises a lamination surface and a function surface, wherein the lamination surface is used for being laminated with the surface of a base material through an adhesive; the function surface is opposite to the lamination surface, and comprises a coupling area for coupling light rays into the optical waveguide film and an outgoing area for outputting the light rays. The base material can realize full reflection; and an optical waveguide is formed between the base material and the function surface of the optical waveguide film.

Description

technical field [0001] The present application relates to an optical waveguide film, a head-up display with an optical waveguide film, a color head-up display, a head-up display system, and an aircraft, vehicle or ship with an optical waveguide film. Background technique [0002] The head-up display is an auxiliary instrument commonly used on aircraft at present. It projects information through optical components onto the optical / electrical display device on the combined glass directly in front of the cockpit. When the pilot observes the scene outside the cabin through the combination glass, he can see the characters, images and other information superimposed on the exterior scene at the same time. The projection focal length is located far in front of the imaging combination glass, and the pilot can easily check the flight parameters at any time without changing the focal length of the eyes, which is very beneficial to the flight work. Nowadays, the head-up display system ...
