The head-up display based on the thin-film field effect transistor has the advantages of rich display color and content, low technical requirement and low cost.
Description
Technical field
The utility model relates to field of display, particularly a kind of head-up display of based thin film field effect transistor.
Background technology
Along with the high speed development of automotive electronics, head-up display (Head Up Display), drive as a kind of collection auxiliary security, and the auto electroincs of the one such as Infotainment also more and more are applied on medium-to-high grade automobile.Concrete, looking squarely HUD can be incident upon virtual image on windshield, so that the running informations such as panel board state and drawn to obtain navigation information to be provided.
The general light source display technique of using of head-up display in the market is highlighted segment encode LED and highlighted VFD(Vacuum Fluorescent Display, vacuum fluorescent display screen) show, but highlighted segment encode LED and highlighted VFD can only show monochrome image, content is simply limited, power consumption is higher and do not support video input, is difficult to meet more and more abundanter demonstration information.In addition, also have laser projection, mainly be used in high-end car, it is expensive, but image resolution ratio is low, and the light path design complexity, and technical difficulty is high, is not suitable for the generally use of domestic depot.In addition, if utilize the windshield imaging monoblock windshield all need to be plated to one deck is special, transparent, the plated film of high index of refraction, increased the cost of car load.
Summary of the invention
In view of the above problems, the purpose of the utility model embodiment is to provide a kind of head-up display of based thin film field effect transistor, described head-up display has display color and abundant in content, and support video to show, can meet more and more abundanter information display requirement, simultaneously, technical requirement and cost are not high.
The head-up display of a kind of based thin film field effect transistor that the utility model embodiment provides comprises: microcontroller, TFT shield (Thin Film Transistor, Thin Film Transistor (TFT)), radiation shield, wherein,
Described microcontroller is used for meter information, navigation data information or multimedia recreation information are converted into to image information, and is transferred to described TFT screen,
Described TFT screen is used for receiving described image information and shows and the corresponding image of described image information,
Described radiation shield reflects for the described image that described TFT screen display is shown.
Alternatively, described microcontroller is also controlled the on off state of described TFT screen for the power supply by controlling described TFT screen.
Alternatively, described TFT screen comprises the high brightness backlights source, and described microcontroller is also be used to controlling the luminous of described high brightness backlights source.
Alternatively, on described radiation shield, be coated with anti-reflection film and reflectance coating.
Therefore, application the present embodiment technical scheme, owing in described head-up display, using described TFT screen to carry out the image demonstration, display color and abundant in content, and support video to show, can meet more and more abundanter information display requirement, simultaneously, process each data message by described microcontroller, be converted into image information, technical requirement is simple, and cost is not high.
The accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, below will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
The head-up display structural representation of a kind of based thin film field effect transistor that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making under the creative work prerequisite the every other embodiment obtained, and all belong to the scope of the utility model protection.
Embodiment:
The present embodiment provides a kind of head-up display of based thin film field effect transistor, as shown in Figure 1, comprising: microcontroller 1, TFT screen 2, radiation shield 3, wherein,
Described microcontroller 1 is converted into image information by the meter information in automobile, navigation data information or multimedia recreation information, and is transferred to described TFT screen 2.
Described TFT screen 2 is be used to receiving described image information and showing and the corresponding image of described image information.The color that described TFT screen 2 shows and abundant in content, and can support video to show, for example described TFT screen 2 can show reversing camera or night vision system CVBS video, has met more and more abundanter demonstration information requirements.
Described radiation shield 3 reflexes to human eye for the described image that described TFT screen 2 is shown, forms virtual image.Described head-up display is driven as a kind of collection auxiliary security, and the auto electroincs of the one such as Infotainment, in order to provide the running informations such as panel board state and drawn to obtain navigation information.
Can be, but not limited to, described microcontroller 1 is also controlled the on off state of described TFT screen 2 for the power supply by controlling described TFT screen 2.
Can be, but not limited to, described TFT screen 2 comprises the high brightness backlights source, and described microcontroller 1, also be used to controlling the luminous of described high brightness backlights source, specifically can be inputted by adjusting the luminance of the described backlight of pulse signal control of described backlight.In this programme, use the high brightness backlights source as light source, image information to be projected on described radiation shield 3 in full-color vehicle-mounted TFT screen, then reflex to human eye to form virtual image.Described virtual image has high brightness and high-contrast, and contrast can reach 3000:1, still can see image clearly when externally illumination is strong.
Can be, but not limited to, be coated with anti-reflection film and reflectance coating on described radiation shield 3.Described radiation shield 3 is independent of windshield 4, in use, without by the interior pressure anti-reflection film of windshield 4 and reflectance coating (being called for short wedge glass), has reduced cost.
Therefore, application the present embodiment technical scheme, described head-up display display color and abundant in content, and support video to show, and can meet more and more abundanter information display requirement, simultaneously, technical requirement is simple, and cost is not high.
Above-described embodiment, do not form the restriction to this technical scheme protection domain.The modification of doing within any spirit at above-mentioned embodiment and principle, be equal to and replace and improvement etc., within all should being included in the protection domain of this technical scheme.
