Embodiment Construction

[0007] Head-up display systems use various projection schemes to direct virtual imagery into the user's field of view. For example, a display image can be generated by a micro-projector, focused and expanded into the field of view. For applications where images are projected into multiple or extended fields of view, one approach is to provide multiple discrete micro-projectors, each serving one field of view or a portion thereof. Examples include stereoscopic near-eye display devices and fixed-reference head-up display systems, as well as systems that direct imagery into forward and peripheral fields of view. A significant disadvantage of this approach is the increased size, weight, cost and power consumption of the redundant micro-projectors and associated optical components. Another disadvantage for wearable stereoscopic display devices is that precise relative alignment of two independent optical systems is required in order to provide a convincing 3D display and prevent e...

Abstract

A heads-up display system includes a micro-projector, first and second viewer optics, redirection optics, and an electronic controller. Redirection optics electronically switchable between a first optical state and a second optical state, the redirection optics being configured to receive a display image from the microprojector to transmit the display image in the first optical state to the first viewer optics, and transmits the display image to the second viewer optics in a second optical state. The electronic controller is configured to switch and maintain the redirection optics in the first optical state during the first interval and cause the micro-projector to form a display image based on the first image data. The electronic controller is also configured to switch and maintain the redirection optics in the second optical state during the second interval and cause the micro-projector to form a display image based on the second image data.

Description

Background technique [0001] Head-up display (head-up display) technology has developed rapidly in recent years. Compact, fixed-reference head-up display systems are now installed in cars. Virtual reality (VR) and mixed reality (MR) eyepieces for the consumer market are also available. However, various barriers to user-friendly HUD technology remain. In fixed-reference heads-up display systems or wearable display devices, one challenge involves the increased size, weight, cost, and power consumption of redundant optical components. Contents of the invention [0002] One embodiment provides a heads-up display system. The display system includes a micro-projector, first and second viewer optics, redirection optics, and an electronic controller. Redirection optics electronically switchable between a first optical state and a second optical state, the redirection optics being configured to receive a display image from the microprojector to transmit the display image in the fi...
