Binocular display system and onboard head-up display system

Abstract

The invention discloses a binocular display system and an onboard head-up display system. The binocular display system comprises two imaging devices separated by a set distance, a beam splitter and areflector, wherein the two imaging devices are used for displaying a left eye image and a right eye image respectively; the beam splitter is used for receiving the light emitted by the imaging devices, transmitting the light to the reflector, and reflecting the reflected light of the reflector to a set position; the set position and the exit pupil position of the imaging devices are symmetrical about the beam splitting plane of the beam splitter; and the reflector is used for reflecting the incident light back to an original path. By virtue of the beam splitter and the reflector, the system exit pupil distance of the binocular display system is increased. A viewer can view a binocular display image of the imaging devices at a position symmetrical with the exit pupil position of the imaging devices about the beam splitting plane of the beam splitter without the need to get close to the exit pupil position of the imaging devices. Thus, the binocular display system can be applied to a wide application field such as onboard head-up display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a binocular display system and a vehicle-mounted head-up display system. Background technique [0002] Virtual reality (Virtual Reality, referred to as VR) technology is an emerging display technology in recent years. It is a technology that uses computers to simulate the real world so that participants can interact with the virtual environment. All VR display technologies used at this stage need to be combined with optical systems for imaging to show special display effects. These display devices often integrate lenses or lens groups for optical imaging. The left and right eyes of the viewer watch different signal sources through optical components such as lenses, and the brain fuses the pictures seen by the left and right eyes to see a three-dimensional picture. [0003] VR display technology is a near-eye display technology that can provide viewers with a large viewing angle...

Problems solved by technology

Although the current VR display technology has many advantages, it cannot get rid of the limitation of wearable devices, which makes it unable to be applied to applications such as vehicle display.
