Detailed description of the invention
In order to more specifically describe the present invention, below in conjunction with accompanying drawing and instantiation, technical scheme of the present invention is described in detail.
The system architecture diagram of present embodiment as shown in Figure 1.Native system mainly comprises: image source, reflective display module and optically functional film.Described image source comprises GPS navigation signal, the speed of a motor vehicle vehicle condition signal of gauge panel, the signal of smart mobile phone and other signals, as the electronic chart etc. of prestrain.Described reflective display module comprises central controller, reflected displaying device, ambient light detectors, front light-source and loud speaker.Image source sends image signal to central controller by wireless or wire transmission mode.Central controller carries out process conversion to the image signal received, and exports inverted image signal of video signal to reflected displaying device.The image projection that reflected displaying device shows is on optically functional film.Ambient light detectors is used for real-time detection external environment condition luminance brightness, and when it detects environmental light brightness lower than setting threshold, described front light-source opened automatically by central controller is reflected displaying device illumination, to ensure to show brilliant image.Loud speaker is used for the sound signal in image output source.
As shown in Figure 2, its detailed description of the invention is as follows for the system works schematic diagram of present embodiment: signal of video signal, as image source, is transferred to reflective display module by wireless WiFi signal by smart mobile phone.Display module is placed on installation frame below Windshield, and the position of installation frame along overall width direction parallel motion within the specific limits, and also can regulate pitch angle so that chaufeur is observed on instrument desk.Optically functional film is pasted onto inside Windshield car.In the present embodiment, the telltale of described reflective display module adopts E-ink e-inks formula telltale, this telltale is not containing backlight, and external environment condition light transmission Windshield irradiates over the display, and the image on telltale reflexes to chaufeur eye position place through optically functional film.The display effect of present embodiment as shown in Figure 3, reflective display module displays be inverted real image, after optically functional film mirror-reflection, chaufeur is it is seen that the upright virtual image.
Reflected displaying device does not have backlight, and when environmental light brightness is lower, the brightness of image of display is lower, and chaufeur is not easily seen clearly.For addressing this problem, need, above reflected displaying device, front light-source is installed.As shown in Figure 4, described front light-source is white light LEDs, one row LED light source and corresponding light diffusion system are respectively installed in reflected displaying device both sides, when ambient light sensor detects environmental light brightness lower than setting threshold, LED light source opened automatically by central controller is reflected displaying device illumination.In another kind of scheme, the irradiation of the homogenizer launched to make LED light source is on reflected displaying device, holding plane light guide plate above reflected displaying device, as shown in Figure 5, the irradiation of the homogenizer that LED light source is from the side injected by light guide plate is on reflected displaying device.
Shield glass is curved surface, and the image therefore on reflected displaying device can produce certain distortion after Windshield reflection, not easy to identify.For addressing this problem, above front light-source, thin film lens can be installed, as shown in Figure 6.Described thin film lens can be special Fresnel Lenses, and these lens can revise the pattern distortion that Windshield causes.In addition, because Windshield has certain thickness, as shown in Fig. 7 (a), image on reflected displaying device reflexes to behind chaufeur eye position through windshield b face, some residual light beam can reflect in a face outside Windshield, be transmitted through chaufeur eye position place through b face, now chaufeur can observe the image of ghost image.In order to alleviate or eliminate ghost image, optically functional film can be sticked in Windshield b face.As shown in Fig. 7 (b), paste in Windshield b face and increase counter-function film, because the reflectivity of described increasing counter-function film is 15% to 26%, image on reflected displaying device reflexes to behind chaufeur eye position through Windshield b face, when some residual light beam reflexes to b face through Windshield a face, can again be reflected back toward a face, thus alleviate ghost image; As shown in Fig. 7 (c), paste anti-reflection function film in Windshield b face, because the transmitance of described anti-reflection function film is higher than 99.5%, most of light beam incides Windshield a face through Windshield b face, reflex to chaufeur eye position through Windshield a face, thus alleviate ghost image; As shown in Fig. 7 (d), at Windshield b face affixing holographic film, because holographic film is only to special angle beam reflection, therefore by regulating the angle of installation frame, image on reflected displaying device reflexes to behind chaufeur eye position through Windshield b face, residue light beam a face outside Windshield can not reflex to chaufeur eye position place, thus eliminates ghost image.
Limited in Auto Instrument desk depth installation dimension, in order to show more information content, can take the form that multiple reflective display screen combines, as shown in Figure 8, different viewing areas simultaneously or side by side can not show much information.As the display block of information 1 in chaufeur dead ahead can display automobile navigation map information; The display block of information 2 of midway location can show chaufeur scheduling information; The display block of information 3 in copilot front can show the free information of passenger.It is pointed out that described reflective display module can be arranged on Auto Instrument desk by the additional after sale installation frame of automobile, also can as shown in Figure 9, be pre-installed in Auto Instrument desk in car production process.
