Abstract

The invention relates to a HUD brightness improvement device: a high-brightness HUD optical system based on laser micro-projection. The device includes an image analysis system, an image receiving system and an eyepiece system, and is characterized in that red lasers, green lasers and blue lasers are used as signal light sources in the image analysis system; an optical Thin film, so that the corresponding red, green and blue light emitted by the laser is reflected, while the light of other wavelengths is directly transmitted or partially transmitted. The HUD brightness improving device disclosed in the present invention has both high brightness information display effect and high definition external environment display field of view.

Description

technical field [0001] The invention relates to the display field, in particular to a HUD brightness improving device. More specifically, it relates to a device for improving HUD display brightness by introducing laser micro-projection and optical film. Background technique [0002] HUD is the abbreviation of Head Up Display (Head Up Display), which first appeared on military aircraft. Head up means that the pilot can see the important information he needs without looking down. HUD uses the principle of optical reflection to project important flight-related information on a piece of glass. This piece of glass is located at the front of the cockpit, and its height is roughly at the level of the pilot's eyes. The projected text and images are adjusted to the infinite focal distance. When the pilot looks forward through the HUD, he can easily compare the outside scene with the HUD. The displayed data are fused together. The purpose of the HUD design is to prevent the pilot f...
