Disclosed herein are devices, methods and systems for implementing a dual image head-up display incorporating a single picture generating unit (PGU). The aspects disclosed herein obviate a blind wall construction and achieve the results created by systems employing two distinct PGUs. The aspects disclosed herein are also directed to an optimized backlighting system and construction for employment with the disclosed HUD systems.

Dual-image head-up display

A head-up display device for displaying a virtual image superimposed over a field of view to a viewer is provided. The head-up display device includes a picture generating unit having an illumination source, such as a laser, to generate a real image following a first light beam. A windshield of a vehicle engages the first light beam, either at an inclined angle or perpendicular, to reflect the first light beam away from the viewer as reflected images. A combiner disposed on the windshield including a holographic optical element steers the first light beam toward the viewer as a third light beam to present the virtual image within the field of view of the viewer. Mirrors may direct and magnify first light beam onto the combiner. A method for displaying a virtual image superimposed over a field of view to a viewer using a head-up display device is also provided.

Head-up display with holographic optical element

Disclosed herein are devices, methods and systems for implementing a beam-splitter with the deleterious effects of double images removed. The aspects disclosed herein are implemented with the introduction of a front and rear surface of the beam-splitter's transparent substrate being in a non-parallel fashion. The aspects disclosed herein may be employed with a head-up display (HUD), an augment reality (AR) HUD, or any implementation employing at least two picture generation units.

Beam-splitter with an angled rear surface

Disclosed herein is a thin-film transistor (TFT) liquid crystal display (LCD) employing an air flow system by the introduction of a gap. The gap may be formed by also introducing a housing portion for selective layers of the TFT LCD. Also disclosed herein is a method of implementing the same.

Thin-film transistor liquid crystal display with an air flow system

Disclosed herein are devices, methods and systems for producing hologram-based indicia for a vehicle dashboard/cockpit. By employing the aspects disclosed herein, indicia (electronically coupled to the vehicle's microprocessor), is lighted and projected in a three-dimensional virtual manner. The aspects disclosed herein may be embedded in various portions in the vehicle and thus, not consume extra space or area required to create virtual images through other techniques.
