Problems solved by technology

Since the transparent reflective film will reflect part of the light and cannot pass through, this will reduce the brightness of the HUD itself, so that it is difficult to use in a high-brightness environment

Abstract

The invention relates to an HUD luminance improving device, namely, a high-luminance HUD optical system based on laser micro projection. The HUD luminance improving device comprises an image analysis system, an image receiving system and an eyepiece system. The HUD luminance improving device is characterized in that a red laser device, a green laser device and a blue laser device are used as signal light sources; an optical thin film is introduced into the eyepiece system, so that corresponding red light, corresponding green light and corresponding blue light are reflected, and light with other wave lengths directly penetrates through the optical thin film or part of the light penetrates through the optical thin film, wherein the corresponding red light, the corresponding green light and the corresponding blue light are emitted by the laser devices. The HUD luminance improving device has the high-luminance information display effect and enables a high-definition external environment display view to be obtained.

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...
