Full-windshield HUD enhancement: pixelated field of view limited architecture

Abstract

A system projects graphics upon a transparent windscreen head-up display of a vehicle. The system includes a graphics projection system projecting light upon the transparent windscreen head-up display and the transparent windscreen head-up display emitting light in a limited field of view based upon the projected light. The transparent windscreen head-up display includes light emitting particles small enough that the transparent windscreen head-up display is substantially transparent.

Description

[0001] Cross References to Related Applications [0002] This application is a continuation-in-part of US Patent Application No. 12 / 417077, filed April 2, 2009, which is incorporated herein by reference. technical field [0003] The present disclosure relates to graphic imaging on windshields in motor vehicles. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] It is desirable to provide information to an operator of a vehicle in an efficient manner and to reduce operator fatigue. Display technologies are known in which light is projected onto a screen and the light is converted into a viewable display on the screen. Such displays for transportation use are known as head-up displays, where information is projected onto the sun visor, on a screen between the operator and the windscreen, or directly onto the windscreen. However, known systems that pro...

AI Technical Summary

Problems solved by technology

However, known systems that project light directly onto the windshield typically require coatings or materials that greatly reduce the transparency of the windshield

As a result, head-up displays are often restricted to a limited area on the windshield
