Abstract

The invention discloses a head-up display optical device comprising a display unit, a reflector, a polarization beam splitter, a wave plate, a beam combiner, and a windshield. The display unit is used to provide first light, and the reflector is disposed on the transmission path of the first light, and is used to reflect the first light to second light. The polarization beam splitter is disposed on the transmission path of the second light, and the second light passes through the polarization beam splitter. The wave plate is disposed on the transmission path of the second light, and is used to receive the second light of the polarization beam splitter, and the second light passes through the wave plate. The beam combiner is disposed on the transmission path of the second light, and is used to reflect the second light passing through the wave plate, and is used to emit third light to the wave plate. The third light passes through the wave plate, and is project toward the polarization beam splitter, and the polarization beam splitter is used to reflect the third light. The windshield is disposed on the transmission path of the third light reflected by the polarization beam splitter, and the third light is reflected by the polarization beam splitter to eyes of a user.

Description

technical field [0001] The invention relates to a head-up display optical device, in particular to a head-up display optical device capable of reducing glare. Background technique [0002] In recent years, with the development of high-tech products, the public's demand for vehicles has gradually changed from the performance of vehicles to the requirements for vehicle safety equipment. Therefore, in order to ensure that the driver does not need to move his eyes to the dashboard to obtain driving information in a complex traffic environment, the setting of the Head Up Display (HUD) can make the driving information appear in front of the driver's sight, so as to Prevent drivers from ignoring external road conditions and affecting driving safety. [0003] see figure 1 , figure 1 It is a schematic diagram of an existing head-up display. The conventional head-up display 100 includes an image generating device 102 , a diffusion unit 104 and an imaging unit 106 . The image gene...
