Abstract
The invention discloses a combined automotive navigation projection display comprising a double processing unit and a projection unit. The double processing unit is used for receiving two video signals and transmitting the two video signals to the projection unit. The projection unit projects the video signals to an automotive windscreen. During running of an automobile, the double processing unit detects contents of the two video signals received, distinguishing a navigation video signal and an entertaining content video signal and controlling the projection unit of multiple angles to project the navigation video signal to the automotive windscreen in front of a driver; the entertaining content video signal is projected to the automotive windscreen in front of a passenger seat. The combined automotive navigation projection display according to the technical scheme has the advantages that the navigation display content and the entertaining content can be projected to the automotive windscreen at the same time, and by adjusting the visual angle, the driver is never interfered by other irrelevant traffic contents.
Description
Technical field
The present invention relates to a kind of composite automobile navigation projection display screen.
Background technology
Along with constantly popularizing of embedded navigation, increasing vehicle starts to install embedded navigation, in process easy to use, also bring corresponding problem, such as: in night running process, the brightness of display is too high, the normal line of sight of driver can be disturbed, easily the normal form of interference.
Present HUD system by displaying contents, can project on the windscreen in front, but has a problem that cannot avoid, and strictly must control brightness and the content of projection exactly, otherwise can cause severe jamming to driver, cause traffic hazard.
Summary of the invention
The present invention is directed to the proposition of above problem, and a kind of composite automobile navigation projection display screen of development, have:
Two-way processing unit, receives two-path video signal, two-path video signal is sent to projecting cell simultaneously;
Described projecting cell, is incident upon vision signal on automotive windshield;
In vehicle travel process, described two-way processing unit detects the two-path video signal content received, and distinguishes navigation vision signal and entertainment content vision signal, controls multi-angle projection unit and is incident upon on the windscreen in driver front by navigation vision signal;
Entertainment content vision signal is incident upon on the windscreen in copilot front.
Be provided with the angle control film controlling projection ray's reflection angle at described copilot front windscreen, this control, film receives the entertainment content vision signal projecting and come, and shows.
Described projecting cell is also connected with light perception unit, detects surrounding enviroment monochrome information; During work, light perception unit is sent to described projecting cell by detecting the ambient brightness signal obtained, and projecting cell controls the intensity of the light projected.
Owing to have employed technique scheme, a kind of composite automobile navigation projection display screen provided by the invention, navigation displaying contents and entertainment content can be projected on the windscreen of vehicle simultaneously, simultaneously, by the adjustment of visual angle, can ensure that driver can not be bothered by the content that other irrelevant traffic are driven.
Accompanying drawing explanation
In order to the technical scheme of clearer explanation embodiments of the invention or prior art, introduce doing one to the accompanying drawing used required in embodiment or description of the prior art simply below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is module map of the present invention
Embodiment
For making the object of embodiments of the invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, clear complete description is carried out to the technical scheme in the embodiment of the present invention:
As shown in Figure 1: a kind of composite automobile navigation projection display screen, mainly comprises: two-way processing unit, receive two-path video signal, two-path video signal is sent to projecting cell simultaneously; Described projecting cell, is incident upon vision signal on automotive windshield; In vehicle travel process, described two-way processing unit detects the two-path video signal content received, and distinguishes navigation vision signal and entertainment content vision signal, controls multi-angle projection unit and is incident upon on the windscreen in driver front by navigation vision signal; Entertainment content vision signal is incident upon on the windscreen in copilot front.
In order to avoid driver receives the impact of the irrelevant entertainment content driven, as a preferably embodiment, be provided with the angle control film controlling projection ray's reflection angle at described copilot front windscreen, this control, film receives the entertainment content vision signal projecting and come, and shows.
In order to control projection display contents, do not cause visual impact to human pilot, described projecting cell is also connected with light perception unit, detects surrounding enviroment monochrome information; During work, light perception unit is sent to described projecting cell by detecting the ambient brightness signal obtained, and projecting cell controls the intensity of the light projected.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
